 |
|
Hi guys,
I am currently doing a straight axle swap on my 65 splitbus
When i took off the nosecone on my splitty transmission i saw it was all oil that was in there:
But when i took off the nosecone on my beetle transmission i saw it was all grease and no oil:
Everything is greasy in the beetle gearbox:
did VW changed it after some years?
Is this normal and can i just fill it with the correct oil?
Thanks! |

no vw did not switch to grease .  not normal . use normal gear lube.
was there any gear oil in it? does not look like it. too clean. odd.
looks like it was re-built greased up and not run? that's a new one.
Steve.

That middle photo looks like brand new grease was put on it for the photo.

| It is not uncommon to have a builder use grease on the main bearing since not a lot of gear lube gets to the nosecone. |

I bought it from a guy which didn't know the condition it was in.. (he bought it in a clean up sale)
I bought 3 gearboxes from him so i think i have got myself a rebuild one,
Nothing is worn, there was no oil in it and the grease looks like brand new indeed..
But no what? Can i just fill it wil oil and wil the grease an oil 'mix'? |

That's an old trick to quiet a gear box noise

I would imagine the whole gear assemblies internally are grease coated too...
You can reassemble, add gear oil and run it, the gear oil will eventually break down the grease... But all will still be lubricated .... I would be inclined to change gear oil after the first 500 miles or so in any case.... Real question may be the quality of the actual rebuild and not the grease...

I paid 230$ for 3 gearboxes including axles and tubes so if it breaks down i still got 2 left  |

I'm surprised MCMSCott hasn't chimed in to mention what kind of Hack puts grease in their trans.
No grease. oil only.....
Grease will get throw off real fast never to return. |

Maybe it was shipped in assembly grease, and expected to be filled with oil by the installer?
Hopefully? |
Yeah that's what i think also.. but i realy dunno what to do right now,
Fill it with oil and hope they will mix? |

Now that I'm starting to dig into transaxles it would be fun to see the results of an experiment like this.
I'd imagine if you filled it with oil to the level plug with the grease there like it is,
That the level would go up as the grease dissolved into the oil.
Pull the level plug before you drain it, as I'm curious to see..!
Also,
Would be fun to only put like a hundred miles on then pull the nose cone.
See if there is enough oil to the mainshaft bearing to wash the grease away..
Bet you the mainshaft bearing would be the last place where oil would dissolve the grease.
People do this kind of thing with motors all the time.
Why not to a transaxle?

Looks like moly grease.
Moly grease is good for gears, acceptable for precison ball bearings but not ideal, potentially bad for syncros.
Packing bearings with grease is often a good idea, but be careful to use the right kind of grease. needs to be compatible with the oil. |
