What is this part called and does it have an O-ring that is leaking?

TIA,

Sorry :o It is on my GS1000S engine.
It has a metal clip that goes over it to hold the wire loom that is not in the picture.

That's just a rubber plug. You should be able to pull it out and press in a new one...I think.

Is it at the end of the oil galley?
The second pic with the "River" was only after a couple of seconds! :(
First noticed it after a trip to Renobruce's a couple days ago.
Cannot seem to find a picture of the part @ Bikebandit.

Eric that part is the countershaft LH plug. As Ed says just pull it out. Drill a couple of small holes, a couple of wood screws turned into the rubber and pull it out. Replace with a new one. It sits up against the left hand ball bearing on the countershaft. There is a diagram on '79 GS1000S under Transmission heading on microfiche.

It's a metal press in plug that covers the LH bearing on the transmission main shaft. There's no O ring under there, nor an oil gallery, just a bearing holding the shaft

The only advise I can give is to pop it out and see why it is leaking. I hate to say it, but it may be a sign of bearing failure. I can't think of any other reason for the oil to pour out like that, other than the shaft suddenly moving laterally

I checked and the plug is about $12

Been doing hi PRM shifts lately?

Me??? NEVER! I try to keep them under 10,000 rpm. :-\\\
So it is the transmission end cap and bearing that I am after?

TIA,

Eric
 
Thanks Don. We were both typing and sending at the same time.
So, tomorrow, I'll get a new bear and seal!
Thanks GUYS!!! ;)

You can't change the bearing without splitting the cases. All you need is a new plug.
 
Oh great. :(
I like to do it right! Drat's!
I'll check the damage, in the morning. :mad:

Eric
 
The bearings have an oil jet that injects oil right into the bearing. Oil leaking out of this does not indicate a bad bearing just the fact you have oil pressure.
Replace the cap. Smear silicone around the edges and get it in before it dries. It will act as a lube and sealer.
Check and make sure your case bolts are tight. Do this after putting in the cap.
 
That's pretty much what I planned on doing if the dealer has the part and I do not see any damage to the case.
Thanks!
BTW, how is your missile running?

Just got the Wiseco 1230 pistons to the machine shop with the cylinder and the head is getting worked so maybe a couple of weeks out on assembly.
Then on to a race motor.
I have a couple of those plugs but they are off an 1100. They are also in Tehachapi which is not hard to get to. ;)
 
Chef, I still have a new set of .424/.424 cams, if you really want to make it crazy!
Still not sure if I will use them on the next build or put them in this engine. :confused:
