Cam Chain Tensioner rebuild

[trdhrdr007]

I've got the typical leak at the cam chain tensioner that I was going to put off fixing until the winter. My throttle cable broke this morning, so I have to order one, & thought I would get cam chain seal & orings now instead of paying postage twice. Anyway, I'm having a hard time finding the oil seal for the rebuild.

I've got a 1980 GS850GT & will be following the instructions on BWringers site. I've looked on the fische at Bike Bandit & can't find the seal. I've also used the parts numbers from BWringers site to try & cross reference the seal without any luck. Can anyone point me in the right direction?

Have you tried torquing the bolts holding the cam chain tensioner in place? O-rings are fairly forgiving, providing they are made from the right material. If you take the old one to a jobber, and tell them that the ring seals oil, chances are good that you will get something that fits and works. But do follow the procedure in the manual for torquing those bolts and adjusting the cam chain tension before you invest in another o-ring.

i'm confident that brian got his numbers right, so i'd just order the parts as per the part numbers on his site

Bikebandit doesn't use suzuki part numbers so you won't be able to do a part number look up without bikebandit part numbers.

The seal to the engine is a gasket. There are a couple seals inside the tensioner that dry out and lose their shape badly. The torque on the bolts won't help if the tensioner is leaking from the seals. Bwringer's Writeup is excellent!

Thanks,

The leak is from the seal or the interior o-rings, not the gasket between the tensioner & engine.

I'm not doubting Brian's parts numbers. I have put those part numbers into a couple of different websites, the o-ring numbers work fine. When I input the number for the seal it says the part number has changed. I don't have a problem with that, but the description reads "o-ring" & the price is what I would expect for an o-ring. I guess I'll try the local Suzuki shop for the seal.

I just punched 09284-10006 (the part number for the oil seal) into Flat Out's fiche, and it came back:

.OIL SEAL (09284-10006 ) $1.49

It also works as expected on a couple of other parts sites I tried, including BikeBandit's part number search. (It's $1.85 at BikeBandit)

So I'm not sure I understand why you're having a problem, or what isn't clear.

One of the reasons for the web page is that the parts fiches do not include this seal for many GS models. If you're looking on the fiche, you won't find it. You have to punch in the part numbers for the seal and sometimes the o-rings as well.

If your cam chain tensioner is leaking, the majority of the oil is coming from this seal, so it's not optional. Replacing the o-rings only won't do much.

I see what the problem is. The first 5 digits for the o-rings is 09280, & is 09284 for the oil seal. I didn't pay enough attention to the first 5 on the oil seal when I copied the numbers. I'll try to get my act together this time, thanks.
