Oil leak from neutral switch

Postby 808johnb1962 » Fri Jun 10, 2011 11:04 am



I have a 1980 Gl1100I with 14,000 miles on it. I have an oil leak that appears to e coming from where the neutral switch goes into the cylinder block. The location is extremely tight and in line with the frame (maybe 1/2" clearance). I'm not sure how to get at this area, or what may be the cause of the leak (stopper?). Any help would be much appreciated. John

There's three possible causes of oil leaking from the switch. The first is that the small clamp, which is held by a bolt to the rear of the switch body, may not be tight. The clamp forces the switch body to squeeze an O ring between it and the the crankcase.
The remedies for both other problems needs the switch to be pulled out of the crankcase.
There are two schools of thought on getting it out.
First is to loosen the bottom engine bolts and use a wedge between the frame and engine to spread the frame. Hmmm... :roll: .
Second is to bite the bullet, support the engine, loosen ALL the engine bolts and anything else enough to move the engine over in the frame. If the switch is corroded into the crankcase like the one in the link below, you will have no choice but to pull the engine out to get at it.
Once you have access, remove the switch clamp and bolt. Laughingly, he now says,' pull the switch body out'. Well, easier said than done but it does just pull out; I mean by that there is nothing else holding it in.
There is a large O ring (18mm x 3mm) on the switch body that can perish over time. Replace it, use rubber grease on it and stick the switch back in.
The other possibility is leakage from the switch body itself. The centre section is a resin? or plastic moulding which is screwed into the steel part ( see the separate parts in the link). It may have become loose in the body. Strip the switch down, degrease everything and re-assemble it with some Locktite or similar on the threads. Clean the contacts while you are at it.

I have replaced this switch before on a GL1000. Its not difficult and there should be a write up on the site-Try a search on Neutral switch.
Its imperative that a new "O" ring is fitted and it does not normally come with the new switch!!!

That's a very true remark. Always get as broad a view as possible. I say that because in fact, I don't always believe me either!
