Title: Location of rear end number and ratio on 230?
Post by: twistedtree on February 10, 2010, 23:14:57

Hi,

I've been able to find the rear axle number and gear ration stamped on the rear end in my 280SL.  It's on the under side on a rib that goes forward from the pumpkin towards the input shaft.  But I can't find it on the 230's.  Is it in the same place?  I don't know if there's just a ton of crap the scrape my way through on the older axles or if I should be looking somewhere else.  I saw one diagram that suggested it should be on the side of the pumpkin (left side I think) around the 1:00 position.

Any guidance would be welcome.

Peter

Hello Peter,

It is on the back side of the main gear casting on the 230SL. In other words on the gas tank side.
There is a semi circular area machined smooth and the number is stamped on it.

Many thanks.  I'll go scraping and digging.  I'm curious to see what ratios I've got.

Probably 4.08 on a US car. Most owners seem to think they're a little low-geared - to the point where stick shift drivers start in second! Mine is 4.08 but I've only ever driven it round the block so don't really have an opinion yet.

I found them.  The '64 has a 3.75 and the '65 has a 4.08.  Plus I have another 3.75 on a pallet in the shop.

Thanks again for the help.
