Stator housing oil leak

#1 PostAuthor: Tonka » Mon Dec 26, 2011 6:04 pm

I have an oil leak coming from the stator housing on my Z1a where the wires come out and wondered what the most effective solution or sealant Is to stop it - fed up of getting my boot covered in oil :shock:

Any advice appreciated

did you change the seal of the housing? if so, you replaced it wrong side up.

Not done anything to it as yet. I was told just fitting a new seal without using some sort of sealant will not stop it leaking. Only want to fix it once :D

take the seal out, clean the wires and the casing with brake cleaner then fill it with black sikaflex, job done :D

Possibly worth 'roughing up' both rubber & casing to provide a good 'key'.
I have used Threebond 1211 in the past, with exceptional results. The important thing is to remove all oil/grease from the surfaces to be sealed, and as already said, brake cleaner is a good way to do this.

Threebond 1211, ain't the cheapest. But your Zed deserves the best. Do it properly & you'll only do it once.

One thing is to make sure that it aint leaking from the actual wires that pass through the rubber .
I fitted a new rubber & it leaked even with kawabond.

Found out after that the wires had been replaced previously with a slightly smaller gauge and therefore not making a tight seal.

As others have said, the real key to getting an effective seal is to make sure that the area, rubber seal and wires are completely degreased. I personally have used cellulose thinners to degrease, then used black silicone sealant- ensure that when applying sealant you get it all around the wires. I usually cut back the braided outer of the wires to expose the plastic insulation , this gives better results too.
