Bosch SDS Drill - top end maintenance
 

Hi,

I have a small sds drill that's given me good service over the years,
but now it seems to be getting difficult to get into its "Hammer
Action" without "pushing it around" against a wall/object (sorry for
non-tech term!).
I was in a Bosch dealer today and he said it needed a top end overhaul
(replacing rubber o-rings and re-greasing, cost about ££2 + vat.

Can this be done easily or are special tools required?
Do bosch sell repair kits (the bosch man said I could not do it!)?

Anyone attempted to do this overhaul?

Thanks

Bosch SDS Drill - top end maintenance
 

I rebuilt my Bosch GBH 2-24DFR and found 2 faults - the mains lead had
an intermittent connection near the drill and the drill/hammer/
rotation-stop switch was dodgy (on my drill this is a purely
mechanical switch sliding an internal cam around).

I found a schematic of the drill internals here http://www.raidiy.com/
(under "spares") though they have recently changed the design of the
website.

I didn't need any specialist tools - but the mechanical internals
weren't the simplest to get back together.

In fact, I've just remembered I wrote this up properly when I did the
repair - see last post in the thread:

I found another site but the workings seem a bit to involved for me to
attempt a service!

I will wait till it gets really bad then pay the money.
