My 85 300SD has a rack position sensor in the injection pump, as I recall this is used to control the EGR valve. I don't think it has any other electronics other than the control of the EGR valve, which I have disconnected.
The intake manifold is different due to EGR valve but the one on the 85 can still be used. I am not sure about the transmission and torque converter. The OM617 in the 300D and the OM617 in the 300SD have a few differences, specifically I have noticed that the motor mount brackets are different and the oil filter canister is different. The oil filter canister on the 300D was designed for mechanical gauge while the 300SD has electronic. I have a 300D motor and transmission in a 500SEL W126. Of course I had to change the transmission tail shaft, cut drive shaft and some other minor modifications.

I do know that there is a difference in the transmission that the shop may not have considered. The nose piece on the input shaft is a different size. & don't remember if the 85 is larger or the 82 is larger. If the 85 is larger, you might have a problem because the nose piece won't fit inside the crank pilot hole.

I have a *discussion* going on here with the shop that is doing the engine replacement on my 1982 w126 SD. I got an engine out of car I knew, slightly anyway, and drove once... an '85 w126 SD. Now that the donor car has been delivered to them, the shop is saying they can't stand by the original, quoted labour as they are going to have to change over my manifold, engine mount brackets, and possibly even the pump as the '85 has a 'later-generation' OM617 that 'has electronics'. HUH. First I ever heard there was a difference between OM617s, any large difference anyway, within the w126 series cars. Someone enlighten me, please and thankee thankee. -- "Mac" Steve MacSween Aylmer, Quebec (Canada) Mercedes: '82 300sd / '82 240d (x2) / '60 220s _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
