Hi all, I'm looking to fit a new crank in my engine after the flywheel decided to make an early escape from the crank nose.

cam 6232 is std A+ crank and also fitted to some tubro engines. Cam 6581 is another A+ crank only fitted to some turbo engines. On 15th May, 2009 TurboDave said:

6232 is the standard A+ crank. Some turbo's got 6581.

12G1505 (or 1505A) is the early (pre A+) 1275 crank.

you must have a special crank if the flywheel is fixed to its nose On 26th Oct, 2004 TurboDave16v said:

To be honest I would use the new crank, but cross drill and harden it. Job done! On 7th Oct, 2010 5haneJ said:

BUT, there are quite a few threads on whether this makes any difference, ie, should the main be cross drilled if used with the plain bottom shell. Yes, cranks fitted with these bearing (plain lower) should be cross drilled even for moderate use. I cannot understand why this was not done in the factory. whats is moderate use, the standard metro turbo had 90 hp and was caned mercilessly by its owners for many a mile, yet these cranks come out of high milage engines with perfect bearings nine times out of ten, maybe one day i'll try crossdrilled mains and see if it makes any difference but as of now its big ends only for me, carl |

Yes, cranks fitted with these bearing (plain lower) should be cross drilled even for moderate use. I cannot understand why this was not done in the factory. In theory, all A+ engines with plain bearings should have failed their big-ends. This does not seem to happen, and I cannot understand why. I've NEVER seen a factory crank with crossdrilled main either. (Apart from Cooper S ones) However, I would always use the grooved main bearing i f I had the choice. The 1505 would be fine for turbo use. Carls says it pays to have it hardened, so this is sound advice. On 13th Jul, 2012 Ben H said:

Without wanting to sound asif I'm ignoring replies, I'm just after a deffinate answer (I have taken on board the replies, and I will be having the crank hardened/crossdrilled).

No, use the groved bearing is NOT crossdrilling and cross drill if using the plain bearing. Unless you listen to Carl (which is good advice) and use the plain bearing on the mains and DON'T cross drill.

Unless you listen to Carl (which is good advice) and use the plain bearing on the mains and DON'T cross drill. Only crossdrill the bigends. For what it's worth, can you even get main bearings with a groove for A+ fitment? I don't think you can. Rich keep telling me that it will be more and more difficult to get regular bearings in the future as well.. When using the plain main bearings, it's the mains that should be crossdrilled. The 1505 will be fine. Don't worry about it at all. It's of the same material as the 6232. On 13th Jul, 2012 Ben H said:

You don't need to crossdrill big ends because of the plain mains. It's the supply to the BEs which is cruical, and the plain mains prevents this half of the time.
