Oil leaking from cam belt cover

Postby sfruechte » Thu Jul 01, 2010 8:55 am



Does anybody have any experience with replacing the cam oil seal on the timing belt side of the cam? I have oil coming out of the cam belt cover and it appears to be coming from the cam side pulley.

I got my Seals from a local bearing and seal Shop... Just be careful with your cam timing when finished..

If the seals are available at a bearing shop, is there any special requirements like heat or pressure or just be concerned with the size.

I haven't started the repair yet, I am also going to get new belts. My bike still has the originals at 216,000 miles. I've retensioned and inspected them many times but have never replaced. I tried to get the Goodyear Gatorbacks at Autozone as mentioned on Randakk's sight but the local Autozone says they have no such belt.

This from the NGW site:

Timing Belts
GL1000 & GL1100 (requires 2)

Honda part #14400-371-04/14400-371-14
Gates #T274
NAPA #250274
Goodyear Gatorback #40274 (AutoZone & ??)

There are some other numbers, but you will have to hunt for them.

Are there any gaskets involved next to the camshaft oil seals between either the timing belt pulley or the point cover? I cannot see any gaskets in the parts diagrams but my Clymer manual mentions them in the reasembly instructions.

You can make your own from the air tubing for aquariums. At any Wally World pet section. :D :mrgreen:

Forgive me, bad day.

These are for the timing belt covers.

Any tips for removing the left side timing belt pulley? When I try to loosen the bolt, the engine wants to turn over, even in gear.
Thanks.

Got me.
Book says to remove the two bolts under the cam sprocket, then the points plate and the bolt holding the point cam, then the six bolts holding the rocker arm assemblies which will make it so you can lift the whole thing off the head. Rockerarms, camshaft and all. Then you remove the bolt holding the cam sprocket to the cam.

You should be able to but some kind of small pry bar through one of the holes in the cam sprocket to hold it in place while you loosen the bolt. You DO have to remove the timing belt first.

And if you have no idea how old those belts are, then replace them both now, cause you have already got them off!

A screwdriver in the sprocket holes worked. I was leary of prying on the pulley. Thanks for your help.

Is it necessary to remove or loosen the cam tower to get the seal out? It looks like it rides totally in the head and removing the cam tower won't really help. Can it be pulled out with a pick or sheet metal screw and a pliers? - Thanks.

Just an update, I completed the job a week ago. It was not necessary to loosen the cam tower bolts to get the seal out. It came out very easily with a long narrow regular screwdriver. I was also able to gently tap the new one in with a large deep socket that fit over the seal and the protruding shaft for the timing belt pulley. I lubed up the new seal with Marvel Mystery Oil and about 1000 gentle taps later it was in. And no leaks so far.

Thanks for all the help.
