Caliper seals and replacements !

[2strokepowerhouse]

Evening all, I'm after a bit of help as I'm at a loose end with this Now. Iv tried two different suppliers now for a couple of sets of replacement caliper seals for a 3tj2 sp and both time they have been wrong. I then sent then the correct sizes needed by measuring the original seals and apparently the seal manufacturers don't make them!! Has anyone else had an issue with this ? Does anyone know which specific model r6 calipers I need to upgrade the originals on the bike and where to source the adapter kits from. Thanks.

All the "spot" callipers are the same bolt spacing and piston diameter ; blue,silver and gold
It is the piston material apparently that is different on the colour reference.
The Thundercat ones have a external link pipe rather than an internal drilling and are not so much desired and hence cheaper.
This opens up more options for a search.
Someone once stated that the bleed nipple was in a different position on various models; I have blue/silver spot
callipers on 8 different bikes, all bought s/hand and the nipples are all in the same position so I do not know how right that info is !

Are the adapter brackets not a one off item ?
I have not seen a manufacturer advertising them.

There is a thread here;

Someone may chime in with the seal kit info.

If you go the blue spot route a compatible master cylinder is advised.

Try a place called Powerhouse automotive the guy is really helpful just give him the piston size and he should be able to hook you up!

According to the parts manual the larger caliper seals are 3GM-W0047-00 and the smaller seals are 3MA-W0047-10.

I would imagine they are still available from Yamaha - if costly.

They come in pairs I think but you would still need 4 sets of each. If you search ebay for the part numbers they do come up. Try ebay.de too!

Well I can tell you straight off, with that info from Chris;

3GM are Yamaha FZR 1000r parts and 3MA are TZR 250 ; both circa 1989 so will still be readily available.

i bought some off ebay - they were wrong but the guy was keen to get the right ones and did.

if you are still looking let me know and i will try to find out where i got them.

Hi yes mate I'm still looking for some, if you could help that would be good. The part number also brings up seals for the fzr 1000 are these the same caliper size ?

I already stated the 3GM prefix seals are from the Fzr 1000.

Your calipers have 2 different sized pairs of pistons;
The larger piston seals originated on the FZR 1000 and the smaller from the 3MA TZR 250.

Your caliper has parts from both models.
If you ordered a pattern seal kit from the 1000; you will only have half the seals you need; the other two will not fit .
If you order genuine parts from a dealer using the two part numbers they will be correct.
If you can find a seller of pattern parts that knows dimensions or what fits what ; he may cobble a full set up as happened with Mang.

The FZR 1000 caliper is not the same as the 3TJ ;only 2 of the pistons and 4 of the seals are.

Edited for clarity.
