Rear oil seal mandrel


Recommended Posts

Gents, does anyone know of an alternative to the steel real oil seal mandrel ? I'm looking at something similar to the clutch plate centering tool made of plastic. Want to check before going for 3D printing or machining my own...

 

cheers

Hi Stef,

 

As far as I know all these mandrills have been made in steel, hopefully NOT to the dimensions shown in the WoM cos it's wrong ! being too large. Easily remedied but a pain after going to the trouble of machining it.

Which is probably why original oil seals are not sealing properly...

Doing a bit of research i found the correct dimension (in red).

I’d be surprised if you could get accurate dimensions using 3D printing, without machining the finished piece on a lathe.

Surely the plastic, being soft when applied, will “Squidge” slightly. Plus as it cools it will shrink.

 

Or can you take those things into account with the software?

I machined one from aluminum for the mad Marx seal, no leaks after almost 5 years and must be 8000miles ( the odometer does not work so guessing)

I have an aluminium Marx type mandrel and an original factory steel one if anyone needs
