900ss 1992 Rebuild - Progress And A Rear Brake Caliper Question

Hi All

Great progress on the 900SS rebuild over the last few weeks (snow permitting). We're about 95% and she starts and runs! Whoop!! I'm itching to post pictures on here but want to wait until it's complete andd functional before I do.

It's not perfect (yet) though and there are still a few finishing off jobs to do, one of which is brakes.

I bought new genuine seal kits all round from a vendor on eBay, quite some time ago (probably just under a year), but it's taken this long to get round to this part. Fronts went in fine, but the rears appear to be the wrong size.

The pistons are 32mm diameter, and I suspect he's sent me the set for the 34mm which I believe was fitted to some 900SS, perhaps later than 92...?

The code on the kit he has sent is 98.5032.60. Can anyone confirm what code should be for a 32mm piston set up? And is that called a P32F caliper?

Thanks, and if he won't take them back (I suspect not as it's been a while), I've a set for a 34mm caliper going cheap!

Cheers

Thanks guys, front calipers are gold. Bike is 1992 (white frame/black wheels, first registered in March 92, though interestingly the registration document say it was manufactured in 1991.

It looks like mine has got a 32mm rear caliper and the seal kit I got was for a later 34mm bike.

I'm in touch with the vendor now and he's going to get me a 32mm set, hopefully!

Cheers

Seems there are two types of 32mm rear caliper, an earlier one with a 2mm width seal and a later one with a 3mm seal, and they swapped sometime around 1992. Mine is an earlier one (P32F) with the narrower seal. I didn't get anywhere with my original vendor, but Powerhouse were knowledgeable and efficient and sorted me out with the right kit from a photo of the caliper and £32.49.

If anyone has a later 32mm caliper and wants a seal kit, PM me.

Cheers

Thanks guys, seals are now sorted... but on to the next issue!

 

Be boring if it all went smoothly...
