M42 Cam Gears NLA

[ThatOneEuroE30]

M44 engines are going to be the (now current) and future donors for us m42 guys. Best way to go here would be to find a local m44 and grab the whole timing case. Deflection wheel for m44 is better and the updated case will direct swap right over.

If only the internals were as good

+1 for the M44 timing case conversion. The 1994-1995 M42 timing case also has the updated guide which replaces the (awful) deflector sprocket. The M44 case differs in that the oil pump rotor is 11mm thick instead of 9mm thick (or something to that effect) so it can provide a higher volume of flow. However, it has no provision for holding the crank position sensor, so you will need a machined adapter. Metric mechanic sells one, I think.

Is the ebay link that someone provided legit? It says they have 5 left. Are those a direct bolt-on for the E30 M42?

See my earlier post in this thread, I called Pelican on this and they insisted they are unavailable. Post back if you get something different please.

Sorry if this has been mentioned before but has anyone tried ordering direct from their dealer yet?

[e30s50dan]

Yes. Couple dealers!.mine checked to see if by chance any other dealers happened to have them in stock.........



..nothing!!

[J0dylan]

Yup NLA from pelican just got the email, I was hoping it was the other part number posted at the beginning of this thread they had said was out of stock. Guess they leave the part listed just to mess with us ahah.

Just out of curiosity has anyone actually had a chain skip teeth or other timing issues due to just the cam sprockets being worn, and not due to a worn tensioner, chain, and/or guide being the real problem? My pulleys are pretty sharp looking but the tips are all oil varnish, no wear has happened there in a long time, as in the chain doesn't make contact with the top 1/3 of the sprocket teeth, making me wonder how it could have worn down so much or if the wear stops once it gets to a certain point? Obviously they are NLA so i'm going to have to run it as-is anyhow but it seems unlikely a properly tensioned double row chain would skip teeth on what is still left of the sprocket.

doubt it. Sounds like someone should look into machining these if they have a cnc machine ;D

Maybe when they're completely unavailable or ridiculously expensive otherwise, because they will be a seriously expensive part machined in small numbers.

[ThatOneEuroE30]

Does anyone make an adjustable cam gear for these? Could always use those and just degree them to stock or use it as an excuse to get some cams lol

[TobyB]

...the stock gear is adjustable...

Didnt know that it was. That explains why i didnt find any.

IIRC it's a 3 degree total adjustment.

Just contacted my local BMW dealer and they stated the part is on back order, but will be in between 7-15 days if ordered.

Going to place an order now to see if they do in fact come in, or if they come back and say they are no longer available.
