You didn't mention brands of engines but odds are good you could buy a
new crank for your good engine, piece the whole thing together. The bolt
pattern on the block is pretty standard.

Beware; I bought an Onan 180 amp welder/5000watt generator years back,
the thing spun with no compression, price was dirt cheap. I figured I
could redo the tecumsa engine with no big deal. Got it home, freed up
the valves, started right up. Ah, ha!!! but no welder/generator output.
Some dollars later I discover that half of the stator windings are
completely burnt out. Onan wanted $1700 for a new stator. Thats what I
get for assuming there is only ONE THING wrong with the unit.

For what it's worth, the motor is long gone, the stator is still going
up and down as a counter weight in my garage.

Ok its home, I see what you mean with the location issue. I will have to
look atthe motor to see what it needs. The motor is torn down and looks to
be done good. the crank is fine it will just take some time to put together
a motor that I didn't take apart. The welder section "LOOKS" good but that
means nothing.

Are these good welders? I have a good Idealarc 300 TIG and a 175 lincoln
mig, so I don't need a welder but it would be nice to have a good
gen/welder. I would think this has to be a better generator than my cheap 10
HP unit fron costco. How well does the CV work for mig welding?

And both the location and angle of the taper are pretty fussy. The angle
of the taper is what keeps things from slipping, the location will
determine the position of the welder armature which will include the slip
rings.

You might look into just buying a new crankshaft. Not cheap but the result
would be a nice running Bobcat

How is the motor connected to the welder? I have the chance to pick one
up cheap but the motor is toast. Just wondering how its joined, I have a
24 HP v twin doing nothing, its not the same brand motor but is it
possible to use a standard motor.


Welder engines like generator engines use a tapered output shaft. On
the Bobcat there's a short taper on the rather short output shaft one
which a plate about 8" diameter is places. The plate bolts to the
cooling fan which is on the armature.

In order to use any engine not built as a welder or generator engine
you'll have to remove the crank from the engine and machine the proper
taper on the end of the crank shaft.
