GL1500 clutch slave cylinder service.

Post by virgilmobile » Mon Jun 29, 2015 6:00 pm



It happend...I started to loose clutch action at the end of the driveway...Hmmmm...Panic sets in...I read that if the clutch slave cylinder leaks on the 1500...it leaks the fluid into the engine...a real bad thing to have brake fluid in the engine oil.
Well almost all my fluid was gone from the master....I prepared for the worse...Bought a kit from a local supplier and got ready to get it done.
I was supprised how easy it was to do the job...Center stand the bike and just a couple of wrenches and it was in my hand.
Suprised again..the slave is vented to the rear of the engine...The pushrod at the engine has its own seal...Just scrape off the gunk and put it back..Bout a hour and a half..
Now,do the year models 90 and up have the same setup.?
No pictures of the finished job,not necessary....I just cleaned it up and put in new seals..a bit of grease on the pushrod for good luck.

You dodged a bullet there.
Good to know that it might be an easy fix, but hope I never have to find out. :D

All the 1500's have the notch on rear cover to drain out clutch fluid in case of slave seal failure, the guys designing these things weren't stupid to not foresee that eventuality. You can see the flaking on your rear cover where the fluid was seeping out. Some drip with large seal failure others just weep and evaporate before hitting the ground but the evidence is always flaking from the brake fluid on the cover.

I see that.
I just thought I read somewhere that the 1500's could leak slave cylinder fluid into the crankcase.
Just wondering if the later models are the same as my 88.

We had two people report that they had clutch (hydraulic) fluid leak into the engine - and one of them had to scrap the engine as a result. I don't recall the years of the bikes involved. From what you have posted, it looks like the engine seal would have to be compromised, as well as the drain possibly plugged, which I suppose is possible. Glad to see that the job is not a big one.

This might be a good preventative maintenance project. If it ain't broke fix it before it does break.

You said you "got a kit form a local supplier" Can you tell us where you found them??

Do those always leak and need rebuilding?

On my 96 Aspy, at about 125, 000 miles I started to get a leak dripping off from the master cylinder. I went ahead and ordered rebuild kits for both the master and slave cylinder. I believe I got them from Amazon and E-Bay. While the slave wasn't actively leaking, there were signs that it had leaked in the past before I owned it.

I rebuilt both at the same time and did not have any trouble bleeding them. When I rebuilt the master I bled the system, got everything working properly and then rebuilt the slave and then bled again. I wanted the system working properly when I rebuilt the slave and i wanted to be able to pump the handle and force the slave off of the housing it is mounted to. Everything worked as advertised and there was not any problems bleeding either time with a mighty vac.

It's rare to read the master clutch or slave needs tending to other than yearly bleeding.

I also had high miles before issues started... around 160K miles.

I've wrenched all my vehicles and others. From bicycles to semi's, not much I can't mechanically do and I'm not a real fan of all this electronic stuff. Personally I believe the electronics should be OEM free (or always available at a reasonable cost) when needed, it's propitiatory and near impossible to fix.
What I mean is, the purchaser CAN DO there own repairs like replace brakes and/or do an engine rebuild etc., but simply can't repair electronics. If the main PC took a dump and it's not available anywhere, that $200 to $800 part will ACTUALLY cost you 25 GRAND to replace. :evil:

ONE COULD make the same argument about electric vehicle batteries.
You ever looked into their replacement cost? :shock:

Good to know it is not a bad job to do. I may have to rebuild mine one of these days. Thanks for the info!
