Nice pictures

MDTM, could you do me a strange favour? Measure (roughly) how long the 'fingers' on your engine stand are (or can spread at max spread)?

I bought a Sealey ES550 only to find that it's fingers don't go nearly wide enough to reach the bellhousing bolt holes on the 390 (it has a huge bellhousing, admittedly) and apparently the next size up Sealey stand is even smaller Undecided

I'm struggling to find one that'll reach.

I will try

I have an ES350 (Clarke one but its exactly the same and from the same factory) and I had the opposite problem as I have no bell housing adaptor plate fitted at the moment so its a bit narrow!

Cheers

The length of a 'finger' and the width between the widest point of the mounting slots on the back plate would be perfect actually - then I can just compare that to mine

Failing that I suppose I'll just have to get some longer fingers made up and hope it doesn't all collapse under the weight Grin

(Mind, that tractor engine must weigh at least what the 390 does? About 350Kg?)

I couldn't quite believe the size of the bellhousing on the 390 though - biggest flywheel I've ever seen!

Mar 2011 at 12:14 Its about 300Kg without the flywheel and adaptor plate (which wont be fitted until its suspended from a crane shortly before mating to the gearbox)

Reply #17 - 22. Mar 2011 at 12:39 Cool - at least I know (if necessary) the 'littler' engine stand will hold the weight, then

Ok, the distance between the hole centres on the fingers is 115mm and max distance the slots will set to is 185mm

So max width would be 415mm.

A few more pics here:

The machined main bearing cap with the thrust bearing placed in position:

And fitted:

I also fitted the crank sprocket (having found the missing Woodruff key) and the crank seal (which was a right pain to do)

Watch out for excessive crankshaft end float on those.
