Fitting WAB28162GB/01 Shck absorber

[Twoten]

I have to replace a pair of 00659070 shock absorbers for the above machine.
The old shock absorbers were fitting when the tub was assembled so can not be easily removed
his machine is similar to the earlier machine where you had to drill out the original shock absorbers and then use a kit consisting of metal plates to strengthen the tub when fitting the replacements.
The tub on this machine already has a couple of holes on the outside of the original shocks and no centre where to drill the hole, also the kit doesn’t have any additional strengthening plates. Just the shock absorber with the push pin and a bush are supplied.
I assume the original shock absorbers should be cut off close to the tub and the new shocks fitted in the spare holes alongside.
Can someone confirm I’m correct about this?
Oddly, BSH hasn’t supplied any tech sheet with the new ones which is unusual when modification needs to be carried out.
Thanks,
Keith.

Yes you drill them out and fit the suspension peg that is supplied

Thanks for the info Kaibart,
Why do BSH no longer supply the tech sheet if this is necessary? They usually supply info even when something is obvious.
On earlier models it came in kit form with instructions giving drill size, strengthening plates plus nuts and bolts.
On this machine, I couldn’t see a centre point in the moulding to drill, so thought it might be a bit hit & miss to drill accurately. This is why I thought the spare holes on either side of the original dampers might be used instead.
Any idea what size drill is required to drill these out?

I manage with a 13mm (biggest size on most chucks) and wobble it a bit as the rear hole is correct size your just drilling the front one. can be a bit fiddly gatting it to break off if you not in the middole sometimes. bosch state 13.2mm

I went on ebay and bought a 13.5mm Blacksmith Drill Bit, these have a reduced shank so will fit a 13mm chuck, typically I have only had to do one since but it made it easier.

Just an update.
I went armed with my 13mm wobbly drill bit as suggested by Dave
I drilled the centre of the peg out and found the peg is a male and female system that locates together as the tub is assembled. This means that after drilling the front of the peg out, the remaining peg can not be punched through a hole in the back, you would have to drill all the way through both brackets which, unless you have an extra long drill bit, you can’t drill straight enough as the drill chuck catches the tub.
Unlike the one in the image, this tub has a second set of holes adjacent to the original damper fixings.
In the end, I felt it would be better to utilise the spare holes for the new dampers. It appeared to be OK on testing.
In the photo, the R/H hole is the drilled hole, and the L/H one is the spare which I’ve used.
Note: The spare holes look like they’re in the same position as the original holes as in Dave’s pictures

If this works, I think it would be far easier to cut the peg on the inside of the supports with a small bladed Multi-tool.

the outer holes look too big to hold the pin , Are they ?

I tried the pin before fitting and it felt OK.
I couldn’t feel any movement between the damper and tub after fitting.

ok
be interesting to find out if this is the bosch answer too
