Well yesterday I spent all day fixing the Rex. I chased an oil leak which turned out to be from the water pump. After that I chased a reverse box leak to the outer seal, I changed all of them. I then had to fix my line lock, radio and then installed a 12 volt plug in the dash. Then I went to change the fluids while the nose was off. I have been having problems with the cluth and with the nose off I noticed that every time I pushed the clutch the rod would return out of the rubber boot covered in wet fluid. My question is if I need to buy the whole master clutch set up or can the cylinder be broken down and re-built. Is this a Kawaski part or a Trex part. Can you buy just the seals? If anyone has messed with this before I would appreciate any suggestions. I think I am lossing pedal pressure and the clutch is not fully engaging.
Thanks

Hey I found a master cylinder. It is a Girling with the 5/8 bore. They are $164.00 at NAPA or on ebay there are two race shops that have them for way less. I looked for the repair kit and the price for a new one was the same as the repair kit.

Just in case anyone else was looking for one.

It would be nice to have a list of part numbers for parts available at US Part stores like NAPA that fit as a replacement for OEM parts on the T-Rex. I have started a list and probably should post. Any Interest Question

The NAPA part number I was given was UP39113. I brought my old one down and the guy went to the stock room and came back with the exact one. I left it there when I was told the price of $164.00 and went on ebay and typed in Girling 5/8. I will try to post the ebay link below of the speed shop I bought it from.

PostPosted: Tue Mar 19, 2013 12:12 pm    Post subject: What about the brake master cylinder Reply with quote

Does anyone know if it's the same m/c for the brakes?

I have a leaking seal in one of the brake master cylinders on my 2004.

I leave the T-Rex in Nth GA, so I can't just go out and check the partnumbers.

If any one knows, I would appreciate the information.

I think I have answered my own question.

From the parts list, it looks like the brake master cylinders are Wilwood combination remote mount kits with 3/4" bore.

P/N: 260-3374
Rebuild kit: 260-3880 according to Willwood site.
Rebuild kit 260-3881 according to Summit Racing.

I will add these to the Parts sticky once I confirm they are the correct units.

Correction to the Rebuild kit P/Ns in my last post:

The correct number for the 3/4" bore is: 260-3881

260-3880 is for the 5/8" bore as in the clutch master cylinder.

PostPosted: Mon Mar 25, 2013 10:57 am    Post subject: More on Brake Master cylinder Reply with quote

When I actually took a look at the brake master cylinder on the weekend, I discovered it is a Girling .75A and not Wilwood.

That is, a Girling remote resevoir unit with a 3/4 inch bore.

The Wilwood unit might work as a replacement, but I went ahead and ordered a new Girling from Averill Racing Stuff Inc. (racing-stuff.com) for $99 and a rebuild kit for $21.99, which seemed pretty reasonable.

I will install the new one and rebuild the old one as a spare.

I will post again once I recieve them to let others know how Averill Racing Stuff works out.

Received M/C and Rebuild kit from Averill Racing Stuff (racing-stuff.com) within two days.

Shipping was reasonable at $9.99. Parts were as advertised. The guy seemed to be friendly and knowledgeable, so I would recommend them to anyone who needs a new master cylinder.

Replaced the rear M/C with the new one and spent hours bleeding the darn brakes, trying to get a firm brake pedal.

When all else failed, I sent a text to Wayne, who responded within minutes and gave us the needed tip. rock

Apparently we had air trapped at the top of the rear caliper that even a power bleeder could not dislodge. Wayne told us to remove the caliper and position it so the bleeder was at the top. A couple of minutes later we had a firm brake pedal. cheers

By the way, if you find one of your brake master cylinders leaking, you might want to consider replacing both. After re-assembling everything, I immediately discovered that the front M/C also has a very slight leak. It was hard to notice while the rear was leaking so much faster, but with the new rear cylinder in place, it became more noticable. I suppose it makes sense. They are identical cylinders with the same amount of use. (I have about 45K on my 2003 model and about 95% of that is mountain riding)

I have installed the Rebuild Kit into the old cylinder and will use it to replace the front one next weekend.

Hopefully it will be time to ride then!!!

Huge thanks to Wayne for his help.
