GL1100A Head oil seal R/Hand rear end

Postby Dale Landan » Mon Sep 30, 2013 1:25 pm



On the 82 GL1100 right hand head tac drive end: Is there an oil seal that goes their or does the fuel pump do the job of sealing any chance of an oil leak. I don't remember if the rear uses an oil seal or if the pump handles the sealing there? The manual is not to clear on this issue, it does show a nice picture of the head break down for the left side with both oil seals shown , but the left side is different due to the tac drive. dplandan@gmail.com

If you are talking about where the tach cable goes in down by the fuel pump there is a small shaft seal there. I had oil leak in that area on my 1980 GL1100, replaced the seal no more oil leak.

The seal I need to find out about would be located on the cam back end of the head. If looking at the left hand cam there are two seals one on the fore end of the cam and one on the aft end that gets covered by a boot and then the cover plate (breaker points are located there on the 79 models). just in front of the tac drive gear spline L/H is where I am in doubt about. Went to my friendly dealer this morning to look at all the parts alas no seal on the aft end of the right hand head sooooooo, I will see what happens when I install the engine and hopefully start it up. Thanks for the info on the tac cable though, I will certainly watch there.

HI all,

this is an old thread but but relevant to what I am doing. I have a few problems with my fuel pump and in the end i've replaced it is an electric job which seems to work very well.

In the process of fitting the old fuel pump flange, I've found that the cam space contained a lot of oil. This was not so always.

In a search for a seal I've found that there are 3 seals in the kit and none to fit the R/H side fuel pump drive end. If one looks in the hole where cam comes out there is a metal seal. I've taken the head apart before some time ago and can't remember what is in there internally to stop the oil leaking out.

Anyone remember?

Finally, I can stop the oil loss, but is the oil supposed to flood the tacho and fuel pump drive space?

No, that space should be dry, and lubricated with some lithium grease. Have a look here: viewtopic.php?f=11&t=161
