M40 Cambelt DIY Replacement Guide

[spannerrash]

Hi guys,

Check out this extremely detailed guide on changing the cambelt and doing a full service on an M40 engine: https://www.spannerrash.com/m40-timing- ... e-bmw-e30/

That should come in very useful to many, I found the guide on the wiki to be a bit vague.

Cheers!

All that farting about with the viscous fan. 32mm spanner on the nut, sharp whack anti clockwise and it’s off.
It’s worth mentioning that later cars from December 1990 used the E36 main tensioner pulley so you’ll need an E36 belt kit.

Depends on who fitted it the last time! Hammer whack doesn't work if it's Loctited and torqued up like the crank pulley.
Good info. about the E36 kit.
