M30 5spd

[Pinepig]

I ended up ordering std. rod and main bearings since everything is apart anyway. Tips on replacing rod/main bearings such as torque #s and order of things?

I only have an e30/e36 bentley manuals, I need to pick up an e34 (535i) manual I guess.

I got you covered on both.

Did some clean-up today on the block/head. Replaced the front/rear seals on the timing/crank covers. Just waiting on new rings and main bearings to arrive now and then it's just bolting everything back, I am going to remove the crank and clean/paint the block to make it look nice.

Wow your really doing a thorough rebuild Jean, that head looks in excellent shape.

[Jean]

Plan on getting another head once this swap is done to add some porting/polishing+cam and a correct chip :)

The cam makes the engine more responsive plus a lighter flywheel, what flywheel do you have?

[Jean]

Getting a 533 flywheel locally. Can these be safely re-surfaced by any machine shop? nothing special about them?

Regular E34 (535) clutch kit will work plug-and-play or do I need to order something specific to make it work with 533 flywheel?

Providing the flywheel is "single mass" you should have no troubles having it properly machined by a shop.

The BMW "duel mass" flywheels are not able to be machined because they can't be taken apart (It's all one piece)

That's my experience anyway.

[Jean]

It is single mass. I am still not sure on what clutch I need to order to make it work w/o having to modify anything... as I understand it OEM e34 535i clutch kit won't be the right one to get as it never came with 533 flywheel.. the guy I am buying a flywheel from is saying that I need to make sure the clutch needs to have a sprung hub?

"You need to make sure the clutch you put in has a sprung hub since its a single mass flywheel, e28 535i"...

True?

Yes.

I paid 50 to get my 533 wheel trimmed down and resurfaced. Call around, BMW specific shops will want to gouge you.

[Jean]

Yes.

Thank you. Other than e28 535i, what other options do I have if you happen to know?

[Lurker27]

E28 M5 spec stuff will work - I've got a stage 3, 6 puck for mine. It's worth mentioning that mye28 is THE PLACE for these niggling M30 questions :)

Someone on the e24 forum had this to add:

"The clutch used on the 260/5 trans (US 533, 633 and 733) has a lower profile to clear the bellhousing on that trans. If you are using the 260/6, 265 or 280 trans then it is preferrable to use the clutch set for the US 3.5l or even better, the M series products. As euroshark mentioned, they work fine with the 533 flywheel (which is the same part as the M series). The lower profile set from the 3.3l will work."

I am going to go ahead with an e28/e34 535i clutch kit since it's complete and I don't have to piece it together.

Sounds good, keep us updated on how it went.

[Jean]

Manifold has been painted, block and valve cover is next. Fingers crossed on rings arriving before saturday.





Picked up a 533 flywheel today as well, I guess the starter that I have is the "bigger" one, not sure if makes any difference to swap for a smaller B35 starter... any thoughts on that?
