Ok I have a 250s with a m129 engine, same bolt pattern as a m130 and I think all the om60x engines.
I want to plan upgrading the gearbox and rear diff, as currently running a 4.08.
The question is, will a 716.630, etc fit the m129? I'm aware that it'll need bell housing work to make the starter able to be install- its on the other side.
Thanks!

The 6 speed wont bolt up to your engine, the bolt pattern is different. It's the m103 that shares it's bolt pattern with the om6xx engines.
If you really want the 6 speed, cut the bellhousing off and weld your old one to it.

You make it sound so easy! I'm glad at least I know what I have to do, luckily the bellhousing on the 4 speed unbolts from the gearbox easily, so I may be able to get it all mocked up out of the car.
Thanks chap!

No worries, let me know if you need any other info.
As long as you get it all lined up perfectly it's easy to do, I did it to get a 716 behind the m117. so far no problems.
The 716 is meant for a daul mass flywheel, so you'll want to shorten the bellhousing anyway.

Yeah there is also a sprinter single flywheel conversion kit too.

Sadly those don't fit the m129/130. They have 8 bolts holding it to the crank, you should have 6.
Just a quick question, have you considered just dropping in an m103 engine? It would make life easier for what your trying to do.

I've just put a deposit on a m104 320 24valves.... just need the flywheel gearbox and I've got a line on a better rear end ratio

Once you have the flywheel, you can get the correct gearbox to work with it.

Yeah, seems it needs to be a dual mass at that.
Just need to find a scrap yard with one to use next time I am in the UK, seems little chance I'll find one over here.

this engine is the KE_Jetronic, or CIS-E

this engine is the KE_Jetronic, or CIS-E Ah, so you've bought the 300-24. In that case you don't need to worry about the cps magnet, either flywheel will bolt up and work. Just be wary of the ezl ignition module, they are a known weak point of that engine and very expensive to replace. One thing I will advise is not to use the normal 5 speed box on this engine, the ratio's don't suit it. Either use the getrag from the 190 cosworth, or get the 6 speed bolted to it.

Yeah, I'm with you on that, 6 speeds are in my future.
The CIS-E is a known problem, however I have a plan for it's eventual demise.
1) keep out an eye in junk yards for spare units, 2) aftermarket control
Ice also got a line on a 4.5 v8 rear axle, trading a drive shaft for one with a much better gear ratio.

Looking at your location, I'm going to assume that there is nothing in LC hughes near bicester any longer?

Can you confirm that the OM606 and the M104 engines share the same flywheel mounts? if so there is a place that makes sprinter single mass flywheel conversions (9in) that bolt to the OM606. I think this is hte case but before I go ordering....

I think this is hte case but before I go ordering.... They do indeed share the same flywheel bolt pattern, and I have one of the valeo solid flywheel conversion kit's bolted to my om606. BUT the diesel flywheel's don't have any ignition pickup points on them, so although it will all bolt up perfectly it wont run. I also have one of the valeo kit's on an m104 twin turbo, but that is running a standalone ecu so doesn't have the problem you will encounter. Where are you based?

Massachusetts, but I lived in bicester, Aylesbury and northchurch, worked in thame for some years.
There is a used DMF for a m103 on German eBay, I might get that and work out a second solution with a valeo and custom pick ups. I'm sure a decent machine shop could fab them in.

If it is from an m103 that will work perfectly, you wont need to play about with the sprinter conversion then. Unless you want to eliminate the dmf? Another idea would be to fit the auto flex plate complete with it's pickups behind the sprinter conversion flywheel. You would need to do some machine work to the sprinter flywheel, mainly removing the sprinter trigger wheel setup and machining circ 5mm from where it bolts to the crank.

Long term I think that is the plan, or similar. I know i much prefer the single mass but a used DMF will get the show on the road as it were.
A better condition M104 spec DMF has just cropped up on the Ebay I may pick that up as well, just to be safe in the short term.
I'll pick up a new clutch and cage, need to get my hands on the gearbox but that's relatively easy here in the northeast. All the cars dissolve leaving just the mechanical parts.
