Clutch Housing Oil Leak

Post by hcgonzalez »



I finally got my 1978 GL1000 running however I have had a hard to find oil leak. It seems to be coming from the clutch housing in the back of the engine and running down. Is there a seal in the housing that may be the cause of the leak?? The service manual does not show any seal.

Yes. It sounds like the leak is coming from a weep hole in the area of the clutch adjustor cover (it's stamped sheet metal and round) and there isn't supposed to be oil behind it. The leak is most likely coming from the clutch actuator rod seal #11 here. The hardest part is getting your eyes in there to see what you're doing. The round stamped inspection cover is held on by two bolts. Take that off and see if there's oil running down from the clutch adjustor nut that's in the center of the clutch cover. If there is, then you will have to pull the clutch cover to replace the seal. You'll also need a clutch cover gasket. Have fun. ;)

Sounds like a Pita with the engine in the frame, but Placerville can it actually be done in the frame? Maybe just removing the rear wheel?

I saw someone do it at the NGW with the engine in place. But, you're right, Fred. Removing the rear wheel would make it a lot easier.

It can be done both ways. The advantage in removing the rear wheel is a long extension,and a universal 10mm socket. If you choose to not remove the rear wheel,a stubby 10mm combo wrench makes easier.

Thanks for the help. It was the seal from the clutch adjuster. A hassle to change but worth not having a puddle of oil on the shop floor. Now if I can get rid of this snow!!

Does the oil need to be drained from the bike to remove the clutch cover? If there's oil behind that little gasket and getting through, it would seem reasonable that there's a lot of oil inside the clutch cover and thus it needs to be drained prior to removing the cover. I'm having a very similar leak and I'll be removing the cover plate tomorrow to see if the leak is from that seal. If so, I'll probably order the two gaskets (#2 and #11) and do the job as well but I want to make sure I do it right and don't dump oil all over my garage floor if possible...

After reading up on it some more, it doesn't look like I need to remove the clutch cover but mainly the lifter door, disengage the cable, remove the lifter retaining bolt and the seal should be behind that. Pull the seal, put a new one in, replace lifter, reengage cable, tighten it all up and replace the lifter door.

Does that sound about right? If I don't have to drain the oil and remove the actual clutch cover, that would make things a lot easier. Although that usually means that there's a lot more to it because nothing is ever that easy. Even if the space is tight and I have sausage fingers. Surely there will be more to it than that...

Hey Guys,

I'm after the Clutch Housing Cover. Not the Larger cover but the one on top. As described by Placerville (below): the clutch adjustor cover (it's stamped sheet metal and round)

The **** I bought the bike from left it off and now can't find it. :roll:

Are they a commonality part on other Hondas, does anyone know?

Appreciate your help!
