Hi Brian, its Thread size.
The connecting rods which came out were M15, I gave up trying to find a repair set/bolts etc for the damaged rod. So purchased 1 replacement connecting rod, then discovered it is completely different to the rest which was part no. 366 030 35 20 80
The 376-030-71-20-40 Connecting Rod For OM352 HMMH were cheaper to buy as a set from America...
Attached should be piccys of the old and replacement part..

Also a note for the sump bolts, be very careful tightening these as the sump is very easily distorted and then leaks like a sieve.
if your sump has m6 bolts tighten to 8Nm, if it has M8 bolts tighten to 9Nm

Hi Oliver,
Are you going of the head size or the thread size when you say M12? according to my literature they should be M15 for the main bearing cap and M14/M15 for the connecting rod bolts.
The main bearing caps should be tightened initial torque (Nm) 50+10 and then final torque 90degrees + 20degrees
the connecting rod bolts tightened initial torque(Nm) 100+10 and then final torque 90degrees + 20degrees
cheers, Brian

Not as much as I'd like, but....
I've been hidden away in the shed getting the engine up together.
I have a set of replacement connecting rods as the threads in one of the originals were a bit knackered! (appears its been apart before..)
376-030-71-20-40 Connecting Rod For OM352 HMMH
They are M12 bolts. The om352 manual specs 90Nm, does this sound about right?
They appear to be the same as 366 030 3520.
Thinking the part number 366 is for the om366 series engine (longer stroke?)The internet says step 1: 40-50 Nm then step 2: 90 degrees

Any news on this?
-
Nice! She's looking good
-
I've most of the bits up together now....
Haha, yep lots of scouring of the web. My best find has to be +.5 pistons with rings, 40 quid each!! :D
-
Back to the bare bones eh, do you have all the components needed to completely finish or are you going to have a fair bit of time on the internet sourcing parts

Tim, I did the same. The mog had been sat in a barn for nearly 14 years before I got hold of it, deffinatly get it up and running to start with. You'll soon find out what needs doing. I'd been driving it around for nearly 3 years before a broken spring and leaky hub seal finally made me start the rebuild!
I'll find a pic. The metal work wasn't too bad under the various layers of paint! :D
The usual, under the headlights, roof hatch, under the window rubbers and the passenger side floor (Windscreen leak..) have all had new bits welded in. The roof was full of filler, allot of the dents pulled out quite nicely...
Hmm, that is only the etch primer, and under seal. A lap of primer then top coat to go!
Next will be the engine, I've a re-honed block in the boot of the car!
The list goes on and on from there.. :)

That looks amazing. I have a little way to go before I am removing the cab. I think by now having been fiddling with the electrics, I may just remember how they go back. I need to get my Mog mechanically sound and roadworthy first as I need to use it to move some kit to be restored before I can turn my attention onto sorting out the cab and doing a final paint job. Looking forwards to seeing more from the restoration. Must have been so satisfying to get the paint on.

Looks like a good start! What's on the list next?
-
That is looking really good, have you any pictures of it before you started.

Finally something to report!!
:D
