Gearbox Identification

[WNX700H]

Hi,

I have a gearbox with casing number 22G1832 rod change with 3.44 diff can someone tell me if it is pre A+ or what it is out of.

Thanks

The 22G 1832 came out at the beginning of 1973.
Should have a small Idler bearing and yes, it is a pre A+.
1982 was when the A+ gearboxes started appearing.
Not sure what it's off though, sorry.

These boxes where used in basically all Mini's between 1973 and about 1980ish (there where some intermediate casings before the change over to A+ was completed). What is the number on the laygear? 22G927 or 22G1040?

OK so what is DAM5626 ??? a+ ?? what was it fitted to?

Thanks

DAM5626 is a rod change A+ gearbox and has a 3 bolt bearing retainer which is stronger than than it's predecessor DAM2866.
The 5626 appeared about 1984 and was fitted to just about every Mini from there on, i think.
Oh, and the 5626 box had a stronger idler housing as well.

The DAM5626 is the very latest A+ type gearbox.

DAM2886 is basically for A type gears but A+ type drop gears. It's one of those casings used during the change-over from A to A+. In terms of DAM casings, there are also the DAM4818 and DAM3220. All of these three are replaced by the DAM5626.
