Bosch SDS Drill - top end maintenance

[Peter Hemmings]

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

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

"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.
