Oil Leaking

Hello Everyone,

I recently changed my mechanical and oil seal because the bike was leaking coolant by the water pump. I successfully changed everything and now the bike is leaking oil from the same area. Any idea what might be happening? Is it possible I didn't put the oil seal in correctly? Or is this something else possibly?

Did you install the lip seal toward the pressure ? or facing toward the engine

Yes thats the seal, but it can be installed backwards, the lip that hugs the shaft must face the engine

Yes I installed it with the side showing in the picture towards the engine. The side with the copper pieces.

The picture is useless, all black, Do you understand the lip side ? this is important as the pressure forces this lip to contact the shaft snugly . copper or bronze means nothing

No I don't understand what lip side means. I'm assuming you mean the side shown in the picture. The side that's not completely flat but has a hollow opening like a dug out circle.

Also, is using silicone necessary when putting everything back together?

Thumbs up

I can see your picture, the copper side is the lip side. Your picture is lip side up. Edit: Most members use rtv silicone on the gaskets, I like to just use regular gasket sealant.

I opened it up and it was set in the correct position however it did have a tear in it. Not sure if it happened because of overtightening or because I damaged it sliding it on the shaft.

I opened it up and it was set correctly however it was torn. Not sure if I overtightened the impeller or damaged it sliding it on the shaft.

Will I need new gaskets also or can I just reuse the ones I just put on??

Just want to make this is right. Should there be a tiny gap in between where the oil seal sits? I guess the question is, is the seal low enough?

Looks good to me, no excessive force needed when installing that seal. Have you seen this thread? DIY: Replacing Balancer Shaft Seal AKA - small oil leak on right side seal

ok thanks. Yeah I did however some of the instructions are not detailed about putting in the seal and how far down it should sit. Thanks though
