oil leak around shift knob

Postby Jd1985 » Thu Aug 25, 2016 6:58 am



I just joined the Goldwing family. I purchased a 1988 Honda GL1500. While I was going through it I recently noticed what appears to be a small oil leak from where the shifter knob mounts into the motor. Is there an adjustment to make to tighten that up or a easy fix to this or what exactly? I appreciate in advance any info!

If you are in fact referring to where the shift shaft actually enters the motor then yes, there is something you can do. There is a shift shaft seal right there where the shaft enters the motor. It needs to be replaced with a new seal. Not a hard job if you want to learn to do stuff on the bike.

There is an article in the "How To" section I believe to walk you through it step by step.

Good luck and let us know how you did.

Also read this regarding the shift shaft brace. Add on that will stabilize the shaft and help keep the seal from wobbling out again.

Yup, flyinrob & dingdong nailed it.
We don't care for oil dripping "harley imitators" around here. 8-)

That seal will take a first timer about 45 to 90 min. to do.

On my last trip, my '94 SE started leaking oil. Today I was in the shop working on the bike. Its apparently leaking oil on the right side of the enging. My drive shaft housing is covered in oil. Anyone care to venture a guess as to where the leak is?
The swingarm on the left side was just dusty. If that helps any. ;)

Pictures would be most helpful. Is the leak forward of the u-joint boot, or aft of the boot? From the engine aft towards the final drive, where is the oil? Is it on the side of the engine, underneath it?

Need a bit more help here with the location. Good pictures will help us...

It's dark now. I'll get out there in the morning and get a better look at what's going on.
I was removing my pre-muffler making a true dual exhaust system when I noticed all the oil. I'll pull some panels and try to give a better description tomorrow.
(Its almost my bedtime now. Getting old you know. :lol: )

No. I'm going to bed now. Don't want to listen to two people telling me how bad Trump and Clinton are for America. :evil:

Finally got out to the shop. Storm came through last night and left a lot of dead limbs in the yard.
My right side valve cover gasket is leaking. Will see if I can just tighten it up a little bit after lunch. ;)

Well I got the engine case guard all loosened up and all those allen head bolts are tight.
The worst part of the leak seems to be right up on the front behind the timing belt cover.
I decided to button it all back up and when the winter months arrive, just replace all those gaskets on both sides.
It hasn't used a quart in over 4,000 miles so I'll just keep an eye on it and ride til winter. ;)

To s--l--o--w down that leak, use some 90w gear oil. :D

Stock up on brake cleaner as parts cleaner, lately it's been cheaper.
I got 14-18 spray cans... goes on sale and I JUST GOTTA get more. :oops:

Good idea about the brake cleaner. It's going to take a bit to clean up that mess. :lol:
Now, about the 90 weight oil. Are you serious, and if so, how much? :roll:

BEFORE you go buying gear oil, let me get some STOCK SHARES first. :twisted:

IF you open that oil leak area again before winter layover you might try this.
After it sat for a night you could use compressed air to push the brake cleaner into the leak several times (dozen?). This cleans out that open oil leak somewhat. Then use tape on both sides of the crack to keep control of the mess, then thumb push black butyl rubber into said leak. IF it don't seal perfectly, it will slow the leak down considerably.
High temp silicone works also but is usually orange color.

I've done this OOdles of times on engine blocks with porous oil and water jackets using 2 part epoxy.

Okay. If I decide to get into it again before winter, I'll keep your idea in mind.
