Tell me how the plate is centered.
And it is possible to obtain a drawing of the plate. Thanks in advance.

Hi Exscom

We made a complete drawing and later CAD-drawing of the crankshaft, engine block, oil pump and the crankshafts movement. From that we step by step searched the position for the oil pump by calculating the length of the chain, circumference of the gear wheels, available space and found a position were the pump could be located without colliding with other moving parts. At the end we put shims in step of 0,10mm between the plate and the screws for the main bearing caps to adjust the tension of the chain.

I will post some more pictures of the plate to give you a good idea about how we did (not today). But I do not want to send CAD-drawings that we made/use. Mostly out of respect to the work producing them, we put down about 3 months of work before we had the final plate and CAD-drawings.

As you can see already in the previously posted pictures we made several versions of the plate for the testing and adjustments. The first pictures posted shows the first version, this was only a plate with 5mm thickness for finding the correct position of the gear wheel. After the correct position was found we made another plate that could handle the transportation of oil, had space for the crankshaft/connecting rod and hole for the oil dipstick. I believe we made 3 different plates for testing before we had the final product. The final plate was then anodized into black. Both to have a harder surface but also so that if any crack occur it shall be easier to find.

I'm glad that you like the pictures from the project and find them inspiring.

Ok.

Hi again

Oil is feed from the pump through channels inside the plate. Oil exits from the plate and are feed into the main oil channel of the engines. Tight to build but working very well.

After final testing and adjustments the plate anodized in black for reason described in previous post.

Thank you.

Wow, that's really good work!
You guys know what you to do!
From first pictures I didn't understand how the plate works, but now I understand it.
I think there's no way to do it better!

Big respect!

[jeandersson]

Thank you Steffen!

I'm glad to hear that you like what you see.

Hopefully it will be a good inspiration if someone is considering to rebuild their car/engine.

Unfortunately I'm about to run out of pictures to post. I have been focused on rebuilding the car and wasn't as good with the camera.

Hi Guys,

The posts are now up to date. You will get some pictures as the project goes along. First up is some pictures from the past weekend.

Any guessing on what we are up to?

No idea, it looks like a new version of your Oil pump-plate.... But let me know!

Hi Steffen

Same material as the oil pump-plate... But this one is bigger and not for the engine. Unfortunately I didn't have any smaller piece of material so there is plenty of wasted aluminum for this piece. I think the pictures below will give a better idea about what's being produced this time

Aha... Looks like an oilpump - Plate for dry sump lubrication....for "outsourcing" the Oil

Also eine Adapterplatte für Trockensumpfschmierung!

This hobby is so much easier, if you have suitable machinery!

Hi.

Sollte der Deckel fürs Diff sein mit Anschluss für Ölkühler.


Gruß Thomas

[Steffen102992]

Stimmt, jetzt wo du es sagst sehe ich es auch.... Es fehlen noch die äußeren Löcher um den Deckel festzuschrauben....
Boah, was ne Arbeit, aber das hätte man doch auch aus dem alten Deckel bauen können.... So ist es natürlich professioneller.

Hi Guys

You are correct it's the cover for the differential. It's an adapter to make the larger ASD-differential from SL300 (in this case) fit with the W201 rear sub-frame. I also took the opportunity to add some connections for the possibility to install an oil cooler later on (if needed).

Almost finished now. In the background you can see the original cover that came with the ASD-differential. Sorry for the old bolts, they will be replaced

I'm also about to install a setup with a 722.634 gearbox. Plan is to run it with a high RPM converter and stand alone controller. More about that will follow.

The plate is quite interesting, since the original differentials can't take much more power (torque) as the stock engine delivers.
I already wreckted 2 "small" differentials, but since these custom parts are hard to get or have to be paid with gold... I guess I have to put myself some more 3.07 into the rack.

We have the exact same experience. The original differential seems to break once the torque is increased. What we seen is that first the plastic washers inside the differential gets squeezed, which results in a increased backlash and then the gearwheel breaks. From what I seen in other projects the bigger ASD-differential that we are installing now are not affected by the same problems (cross my fingers).

I do not know the original differentials, just W124 ASD, but wouldn't it be possible to replace the plastic washers with selfmade parts made out of metal or a stronger polymer?

I never had a complete broken one, but strong abrasion on the wheels and the diff became louder than my exhaust. We removed the ASD sensor once and it hat lots of metal sticking on it. Not sure if the plastic part is really the problem.

Suppose it should be possible. Is there someone who have tried? I hope my problems shall be over now so that I can just forget about the differential
