Test Drive / W116 S270 CDI
Last post by Jackhammer - 02 April 2024, 10:03 AMHi everyone!
This forum helped me A LOT with my W116, so i finally decided to share with you all my project.
I bought mine W116 300SD in 2018. It sat since 2005 in a garage, and was in a quite sad condition. Many parts missing, interior was dirty, all seat springs were shot. Brakes seized, shocks non-existent, half of the ac components non existent etc. But the worst crime,- engine converted to naturally aspirated om617, with 4 speed manual box.
Since it wasn't nowhere near it's original state, I was inspired to make something interesting out if it, Over the years I sourced most of the missing parts, completely overhauled braking system, as well as suspension and interior. I always had another mercs, and did engine conversions for my self and other people,- mostly to om60x engines, with performance injections pumps. But I personally don't like the powerband of IDI engines, so om612 CDI was chosen. I chose om612 instead of om613 mostly due to space constraints.
I started with the conversion in July of 2023. My goal was not to hack up the chassis and/or body, and to look as original as possible from the outside to the untrained eye. After lots and lots of fabrication, trial and error, as well as tinkering with the wiring, - engine is in the place, mated to 6 speed manual gearbox, powering the 2.47 rear end.
It's not done yet, I still need to clean up the wiring, hide the ecu, connect the AC system, and a sea of other bits and pieces, (interior and exterior wise) but it's finally coming together.
I will deliver some high quality photos, as well as videos,- as soon as i have it registered and pretty much complete

I have about 6 sets left.
Another member sells the front cups.

If you have an extra main valve, please PM me. Post some pictures if you want on this thread, or any pictures regarding the 4-corner HPS system, W126.
I think if I paid attention, I would have never gouged the tube. Also, having taken one apart, I think my learning curve is already 50% or better. I just zipped through ball joint removal, tip removal, et cet. I just got the tube now with the 2 end pieces. I am thinking the other ball joint is fine also. It was incredibly nasty, and gunked up. Just got done cleaning it and it's still nice and tight. I think new grease and a new boot and I'm in business.
I am narrowing down the nylon pieces inside. I believe they are called "L" scrape type seals made by Hercules. It's actually a British design. The O-rings are 70 durometer, which should be pretty easy for those. Once I source the nylon inserts, it should be downhill from there.
I am hoping the front struts share the same nylon inserts. I thought I found them over the weekend, but I was a little off base.
I know if I contacted Star Motors they will probably not disclose their info. lol
The trick right now is getting the exact specs for the nylon seals and O-ring
Hi! Did you ever went through with this project ?

Test Drive / Re: My 6.9's
Last post by rumb - 01 April 2024, 04:52 PMPartial improvement. Trying to bleed air out of system. Got corner to go up about half way so far. Will rinse and repeat a few more times.
After I turn engine off and bounce corner you can hear fluid (and probably air) sort of squealing as it travels thru system. I doubt just fluid would make noises like that.
My car is earlier without the bleed screws in the system.

Last post by raueda1 - 01 April 2024, 12:47 PMQuote from: Magyar on 31 March 2024, 07:18 PMHi I have a mercedes 280 s e and when I drive 110 km/h the revs are at 40000, this seems too high, why are the revs so high??Unless you have installed a turbine engine I'm guessing you meant 4000 rpm? Gear ratios are HERE. You can calculate rpm and speed. Regardless, as an order of magnitude guess, it sounds like you're in 2nd gear. Or maybe third. You'd need to do the math to be exact.
Thanks

Last post by rumb - 01 April 2024, 10:34 AMMB has long designed engines that run all day at 4K rpm. This increases fuel economy as well as stays in power range. Compared to lazy american cars that run at 1500 rpm this seems odd to those not used to it.
PS put your car in your signature and then it will always be visible to everyone.
