When the pressure plate is tightened in place, the clutch disc is held
very firmly in place.* Without aligning the splines first, you will
likely have a very difficult time inserting the transmission shaft
through the clutch disc and into the flywheel.


Most DIYs seem to gloss over this step.

As an example, this DIY at time 331 seconds, simply shows the bright red
centering tool already in place! :(

That same video, shows at time 352 seconds, a *different* centering tool.

It's one of those things you don't necessarily think about that screws
up someone without experience in the job. It's like the whole angle
discussion. They might show sliding the transmission back in place like
a stick of butter in a hot frying pan but after you've laid on your back
sweating and cursing trying to rattle a heavy chunk of metal just right
to get it started in the splines you realize the importance of being
able to line everything up nicely.

Amen to that.

This video, at time 92 seconds, says what you say, which is that the
"crankshaft and topshaft" must be aligned "along the same axis".
https://youtu.be/S5xSOy03NAg?t=92

They show that procedure of aligning the two shafts at time 409 seconds:
https://youtu.be/S5xSOy03NAg?t=409

. Tip the front down an twist the front of the transmission to the
driver side
. Lower the transmission (most seem to do it by hand even when they
have a jack???)

Depends on how strong/old you are.


This video, at time 62 seconds, shows a guy wrestling a Toyota
transmission
up but then using a regular floor jack to hold it there (but he has to
adjust it a lot).
https://youtu.be/NcTmlO9XN1E?t=62


Yup. Been there, done that, but without the dog... There seems to be
audio so that guy is very self controlled. Generally you last there
screaming "F**k! F**k!" like some New Age mantra. Then when your well
meaning, nice old lady neighbor wanders over to ask if you're all right
you sort of have to come up with a polite reassurance through gritted
teeth hoping she'll go back to her soap opera.


Any mechanic who doesn't swear like a trooper hasn't been there, done that!

It's really fun when the transmission is heavy enough to challenge your
bench press capabilities and you realize you've got one more rep left
before it's going to come down on you.

A hex bolt that screws into a threaded hole is a *set screw*.
If it has a recessed hex, then it's a cap screw.
But it does depend on which part of the world you're in too.

It is remarkably easy to do on the BMW 2002.... you can have one person
lifting it on a couple 2X4s while another person rocks it back and forth
until it slides right in. The five-speed Getrag on the E28 isn't that
much worse. You can drop the damn transmission in the driveway without
a lift and have it back in the same afternoon. Part of this is because the
manual is very good, part is because the transmission is light, and part
of it is because you can actually see the thing well enough to see that it's
lined up or not.

On the other hand, you couldn't pay me enough to do a Ford Econoline again.

I love the little toolkits you can now buy very cheaply for that sort of

That's the limit of adjustability.

How do you measure that the engine is "level"?
I have levels, of course.

In fact, I "tried" to measure the level of the transmission when I did the
lube change a few days ago. Here is a picture that I didn't put in the DIY
of me trying to figure out if the tranny is level.
https://s26.postimg.org/d5pocivnt/level.jpg

I gave up because I didn't have a good flat spot.

I knew the garage floor was level though.
https://s26.postimg.org/d53ughagp/00...uid_Change.jpg

So how do you check the level of the engine?
Do you just try what I tried with the transmission and look for a suitable
flat spot?

Leveling the engine has NOTHING to do with it. The vast majority of
light/medium duty vehicles have the bell housing integral to or
dastened to the transmission, and without dropping the back of the
transmission the bell housing will hit the firewall before the
transmission can come out. Therefore the engine and transmission MUST
be able to tilt - and often quite a bit - to come off of the engine in
a straight line, and to go back onto the engine.

It is the *critical spec*. Without it you can easily end up with a
buckled clutch plate or difficulty getting the shafts aligned. The
tractor I did recently had a dual clutch, one plate was for the PTO, so
there were two splines to line up plus a pilot shaft. Flexibility is key.


Well, then, I'm officially edified that tilt *is* the spec!
https://www.harborfreight.com/automo...ion-jacks.html

How much is the "minimum" tilt needed in degrees?

This $160 transmission jack, for example, says:
Saddle tilt backwards (deg) 8°
Saddle tilt forward (deg) 55°
Saddle tilt side (deg) 30°
https://www.harborfreight.com/800-lb...ack-60234.html

But this $100 one says:
Saddle tilt forward (deg) 5 deg.
https://www.harborfreight.com/automo...ack-39178.html

This $300 one says:
Saddle tilt forward (deg) 55° forward, 10° back, 12° side
https://www.harborfreight.com/automo...ack-60240.html

Obviously more is better in most cases, but what is a minimum required?
Forward = ?
Back = ?
Side = ?

I think they have the directions mixed up unless they are talking
about a front drive. The side to side isn't terribly critical in your
application, and the rear tilt needs to be more than the front - As I
said before, a bare minimum of 15 - 20 more likely - and if it can
tilt 30, so much the better. The adapter saddle previously shown
spec'd 30 forward and back - perfect. For heaviuer transmissions - and
4X4 with transfer case, the side to side tilt ispretty handy. For a
relatively lighr RWD, not so much.

This is really good to know for a whole bunch of reasons.

One is that the saddle will be easier to store and less money than a
complete transmission jack.

The other is that the floor jack is the beefiest one that Costco sold years
ago (maybe ten years ago?) where the only thing I would change if/when it
breaks is I'd go to aluminum instead of the heavy steel.

How does this "Floor jack transmission adapter" model 39152 look?
http://images.harborfreight.com/manu...9999/39152.pdf

Unfortunately, it looks like it's no longer sold though.

Looks decent. General generic adapter sold by many importers under
many brands.

A friend's wifes BMW snapped an aluminum bolt on a motor mount,

he took it apart and was able to remove the threaded portion of the

mount that fastens the engine to the chassis - and I believe it was
the bolt that fastened the mount to the engine block.


MAYBE they had this there as part of crash protection... IDK why they would

I hesitated when I wrote that. The axis of the engine's crankshaft when
it is supported has to be the same as that of the transmission's input
shaft. The whole lashup could be at a 20 degree angle relative to the
floor as long as both match.

Another way to look at is the perpendicular mating surfaces need to have
matching angles.


Thanks for clarifying that the engine needs to be in line with the
transmission shaft, where they look (to the naked eye) parallel to the
garage floor that the vehicle will be parked on.

They are pretty close untill you remove the rear mount and pivot the
engine back to slide the transmission out from under the floor -
without the bellhousing hitting the floor.

Pressure plate bolt torques? As critical as flywheel bolt.


Thanks. I appreciate your advice because most of the DIYs I read were just
words, where the words meant something only to someone who has already done
it.

For example, I didn't even know the pressure plate had bolts.
The DIYs I found just said "remove pressure plate" so I assumed there were
no bolts.

I added an empty spot for the pressure plate bolt torque, which I will fill
in when found!

Learn to differentiate between pedal free play and release bearing free
play - you should be able to feel two (2) distinct steps - pedal play,
then release play.


I admit, the whole "clutch pedal adjustment" procedure is a fog to me at
the moment. I can only distinguish, when pressing a clutch pedal, the
distance that nothing happens, versus the distance that something happens.

Some systems work on zero free play at the release
bearing (e.g. carbon thrust block types) but, in the case of hydraulic
systems, there is *always* a need for free play at the master cylinder
end. This is to ensure correct operation of the MC hydraulics.


I need to study that further to understand it better.

No mention of what you should be inspecting for, both on bits you intend
to replace and those you intend to refit. Flywheel face, for instance.


That is a good point that I don't know what to look for.
In the case of the DIYs, everyone shows a picture of a chewed-up clutch,
but I'm expecting to replace the clutch, so that won't matter much.

Also most expect to resurface the flywheel.
And most expect to replace the two "bearings", the throwout & pilot.
And they expect to replace the "rear engine seal".

I'm not sure of what else that people routinely inspect to replace.
In my case, I'm not expecting any "damage" since the transmission is
essentially working fine (the clutch is merely "due" for a change based on
time and miles).


Like a said, "time" or "mileage" to replace a clutch is generally BS.
It is "on condition" - meaning dependent on operation.
No mention of cleaning and safety precautions associated with same.


I'm not sure what 'cleaning' is needed other than wiping off old grease.


You will soon find out. every bit of what USED to be the clutch plate
(friction material) is now dirty, sticky, black dust fouling
everything in sight!

. It is said to put it in gear when aligning splines (allows output & input shaft to turn)

Top gear always.


The thing I didn't get is how I'm supposed to put it in gear when it's
already removed from the vehicle?


Thke it OUT in gear.

Is it easy to put a transmission in top gear when it's just sitting there
on the garage floor without a shifter mechanism?

Sometimes. Generally not. REMOVE the transmission IN GEAR.

We had such a generic alignment tool available. The issue was that it

need to pack it up with tape. Coupled with 4 alignment dowels, made out
of bolts with heads removed, fitted into the block, the mating up
process was the smoothest I'd ever encountered.


What I don't understand, since I don't even know why this "alignment tool"
is needed, is what happens if I don't have this special alignment tool?

The air will turn VERY blue before the transmission gets back into
place. The clutch disc needs to be installed virtually 100% concentric
with the crankshaft/pilot beating/ flywheel, and the ONLY way to do it
easily is with a dummy spline - AKA a clutch alignment tool. You can
make one if you can't buy one - I've made them from a broomstick in a
pinch - I've also used a deep socket wrapped with tape - but I've
worked in the "bush" in central/east and west Africa where you end up
making more than you buy - - -

Personally, I use bolt when it's threaded into something that has matching
threads (these are generally relatively shallow angle threads).

I use screws for when it's a steeper-angled thread that "bites" into the
material (often with a sharp point).

Bolts generally have hex heads (for sockets) but not always.
Screws generally have screwdriver notches but not always.

The difference is, to me, in two things mainly:
. The angle of the threads (screw threads are steeper)
. The mating material (screws make their own mating threads)

I might be wrong though as I don't follow the McMaster definition exactly.

So what about a "cap screw" or a "grub screw" or a "machine screw"
or a "set screw" - all od which are ":technically" bolts by your
description ???. There are other examples.

Because you can't just wiggle it back and forth until everything slides into

than one person can lift it becomes a problem. So you have to line everything
up so it's all straight in a line and then push it together straight. It's

Maybe brutal but Fiat vs Mechanic is a death match.

Try Moscavitch or Lada Vs Mechanic on for size. Or Peugeot - or old
Jag.


+1 Indeed.

I did defeat a Simca, making it actually drive away, against
its nature. That was touch and go for a while.

How hard is it to replace a clutch in a 5-speed manualtransmission?

The owners manual says the car must be level when you check the oil.

That direction is for people who are unable to make mental allowances
for situations that aren't 100% spot on.

We had such a generic alignment tool available. The issue was that it
didn't handle the dual clutch system on the tractor at all well. The
local dealer didn't have a *factory one* for the tractor but he lent us
one he'd made up on a lathe. It wasn't a firm fit however, hence the
need to pack it up with tape. Coupled with 4 alignment dowels, made out
of bolts with heads removed, fitted into the block, the mating up
process was the smoothest I'd ever encountered.


What I don't understand, since I don't even know why this "alignment tool"
is needed, is what happens if I don't have this special alignment tool?

The air will turn VERY blue before the transmission gets back into
place. The clutch disc needs to be installed virtually 100% concentric
with the crankshaft/pilot beating/ flywheel, and the ONLY way to do it
easily is with a dummy spline - AKA a clutch alignment tool. You can
make one if you can't buy one - I've made them from a broomstick in a
pinch - I've also used a deep socket wrapped with tape - but I've
worked in the "bush" in central/east and west Africa where you end up
making more than you buy - - -

You too huh? In my case it was the jungles of SE Asia. The *buy* was
never an option. A warehouse restock took 8 months. Air freight a
slightly more convenient 3 months. Did I mention the locals knocking off
all the tools? They could give the Romany lessons.

Personally, I use bolt when it's threaded into something that has matching
threads (these are generally relatively shallow angle threads).

I use screws for when it's a steeper-angled thread that "bites" into the
material (often with a sharp point).

Bolts generally have hex heads (for sockets) but not always.
Screws generally have screwdriver notches but not always.

The difference is, to me, in two things mainly:
. The angle of the threads (screw threads are steeper)
. The mating material (screws make their own mating threads)

I might be wrong though as I don't follow the McMaster definition exactly.

So what about a "cap screw" or a "grub screw" or a "machine screw"
or a "set screw" - all od which are ":technically" bolts by your
description ???. There are other examples.

Yes, literally hundreds of different types. ;-)

Because you can't just wiggle it back and forth until everything slides into
place. Well, you CAN do that with a VW bug, but once the thing gets bigger
than one person can lift it becomes a problem. So you have to line everything
up so it's all straight in a line and then push it together straight. It's
not as hard as some people are making it out to be.... unless you have one
of those vehicles where it is.

except leveling has NOTHING to do with it. it is just lining both
the engine and tramsmissin on the same plane.


Once again I phrased it wrong. Theoretically if the transmission
assembly and floor were both dead level you wouldn't need any tilt in
the jack. The greater the angle respective to the floor, the more tilt
required. I did not mean to suggest leveling the transmission was
necessary or even possible in many cases.

XK120, shudder. But they were so classy... Never heard of a Moskvitch
but from some of the photos it looks like a rebranded 1962 Rambler Classic.

Okay, you've mentioned them. Read on......

Here is my tentative DIY (composite from a few non-correct-truck DIYs):


Why not just use the correct DIY, from the place you mentioned?

You could sign up (it's free), and access info on manymanymanymany cars + trucks.
(Lemme guess... you didn't know they had repair info?)

I didn't but then, it's a different country to the one I live in.

What I saw as being useful was they give a good rundown on all things
you need to think about when removing the gearbox. A lot of people, when
removing a gearbox, pay scant consideration to the effect that
engine/gearbox tilt have on underhood bits and pieces; top radiator
hose, wiring, linkages, etc.
