Gearbox code .

Had a scratch away at a spare gearbox and wondered if anyone recognizes the code ??
I THINK it reads CE (1600 71-75) but can't find anything else relating to the rest ...

Any gurus out there , possibly @busmonkey ??

CE is the boggo 1600 box.

 

CE: Standard gearbox for 1.6l/50hp engine from 9/71 and 1.7l engine, up to 7/73 gear ratio 5.375 (8:43), from 8/73 gear ratio 5.428 (7:41)

See http://www.michaelknappmann.de/bulli/michaelk/vw_bus_d/getriebe.htm

 

Just snapped a pic which I should have done in the first place !!

Not very visible but probably CE or CF also any idea about the numbers ?? possibly factory serial refs ??

Are you looking in the right place? From memory, the code is stamped on a flat, machined bit, not the case.

 

Just below the filler ...

Got me thinking now , I might nip up and have another look tomorrow. Certainly rings a bell being stamped on a machined plate - this is definitely on the case , possibly not even from a bay ??
Came with an engine I bought and sold years ago but never tried bolting them together !

Not so much a plate, rather an oblong bit on the casting machined flat so they can stamp the gearbox code on it. Stuff moulded into the casting itself tends to be the part number etc eg "091..."

Then like engines, if you send a gearbox in for refurbishment, your 002 gearbox comes back with some of the improved parts of the 091 but not the plastic bit of the 091 that melts if you let the oil get low..

 

Which bit is that?

 

Maybe the cage for the bearing you see under the nose cone? (pure guess).
I know when I revved my fast engine to 6,000+ rpm the (1968 box) "some sort of metal" cage disintegrated so maybe that got changed to something tougher. That bearing had as much space between the balls as balls. That's speculation BTW, just to be clear.

 

But doesn’t a 002 have the same, or similar, bearing cage as the 091?

 

I don't know, I'm guessing.
A game until Mike let's us know.

 

I always thought the 091 (6rib)was a specific gearbox for just the 2ltr ? Never realised it was used on the very late 1600 bays .

 

Same here

 

It appears that it was on the later boxes (CU, CV, etc which my '78 would've had originally)...in 3-rib guise. So, 3-rib 091s appear to exist.

 

I don't think 091 = 6 rib. hence the confusion.

 

So later 3 rib boxes have the same ratios as the 6 rib bs fitted to the 2 litre engines?

 

No.
