If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

Help splitting crankcase needed

I am ready to split the crankcases on my 1982 550m and would like to know how many bolts should have come out particularly the top case.

On the top case I took one bolt (m6) out near the oil pressure thingy and a nut of a stud next to the drive shaft (see attached pic) are there any more I have missed on the top?

On the bottom case I have taken out 29 bolts altogether m8 & m6

If I have got them all out anyone know the safest way to seperate the two cases experienced hands required.

To split, I tapped mine around the edges, then hit it firmly a few times at the front. Came right apart. It helps to put it on the bench so it's upside down and pull off the bottom case first.

Clean/paint the bottom case, then transfer the internals as necessary from the top to the bottom until your ready to put the bolts back in.
 
Have you removed the starter motor? There are two bolts under it. To split the cases I used a broad bladed (4") paint scraper, gently worked it into the joints all the way around; this also assured me all the bolts were out, then I slowly pried the cases apart with the scraper so theforce was spread out.

Thanks for the replies guys,

I have looked on one of the parts fische and looks like that is all there is in the top case. I,ll go and give it a Knock with a piece of wood and hammer.Not going to resort to the paint scraper method just yet but you never know.
 
Take lots and lots of pics when you take it apart. I did my engine not long ago but took a month to get the needed parts. When it was time to put things back together the pics came in handy as I forgot where a lot of parts went.

Well split the cases without hammering or prying to see how take a look at the pics. Hope this is a really top tip and not just something an idiot would do. I bow to you to judge my actions.\\:D/

Now why did i split the cases?
