Magy oil seal

Well i have decided to live with the gearbox sprocket oil leak about one drop every half hour. Next job replacing magy oil seal. The first seal i bought was an original bakelite type thing that had shrunk and would not fit i replaced it with a modern type that fitted a spare pinion i had.Today i removed timing cover and the pinion all went well until i tried the seal in the casing recess but the recess has been floged out the seal just floats in the recess so that stuffs that i put it in anyhow. There was no seal in it at all when i stripped it. I cant see it doing any harm hopefully.

If the slop is not tremendous, you can usually save the day with some 'Loctite' Bush and bearing retainer. If it's loose in the housing, it will undoubtedly spin with the pinion and make the matter worse. Ron

Re: Magy oil seal

You might also get away with Araldite or 'liquid metal'...However, the problem is to position the seal more or less concentrically to the mag armature...The housing usually wears well 'out of round'...

I made a jig to pick up on the original centre which enables me to carry out a machined repair to the casing that restores both size and centrality...

Unfortunately that can only be carried out with the engine fully stripped...

If you use Araldite or 'liquid metal' thoroughly clean the case with paint thinners or similar...Apply the 'glue' and then position the seal centrally by eye before allowing the 'glue to harden...Ian

Yes araldite the journel is well worn oval shaped. if i study the fitment and use the pinion to press on the seal it will be centred. ill try it first with witness marks.
