Need help swapping 85 617 into an 84 300SD
Hello all - thanks in advance - I have access to an '85 300SD engine but my car is an '84 300SD. I am told that the major difference between 85 and previous 617s is the injection pump. Anyone know if it will work to use the '84 IP on the '85 engine or will other alterations be required?
If this looks like it will work, I will be coming back for advice on all the things I need to do with the replacement engine before installing. Once again - thanks in advance to all!!! |

Why not transplant the whole engine directly, without messing with the IP? I haven't heard about any differences in IP between 84 and 85.

Well depends. An '84 California would be the same setup as the '85 Federal.. They both have the electronic rack position sensor. (the '85 California is different because it has a trap oxidizer after the turbo, but still has the rack position sensor on the IP) But if you have an '84 Federal, the IP didn't come with the electronic rack position sensor. You could still use the motor, just leave the sensor unplugged. If you are getting the '85 California, I suggest you use your '84 exhaust manifolds and turbo setup.

I've got an 85 TD. There are no wires going to the IP so I don't see how it can have an electronic rack sensor.

You positive? Hmm.... I never seen one without it. It would be located between the IP and engine block. Take a pic I would like to see that setup.

Number 64 is the rack position sensor.

The rack position is monitors by EGR computer and controls the ARV and EGR. It may look like vacuum lines.

Interesting. Does it control anything else? The PO replaces the ARV turbo with a non ARV one.

As far as engine functions, the EGR Computer controls only the EGR and ARV. The tachometer functions through it via the flywheel sensor.

this is my first in on forum, have in MY garage a super ClEAN, 300SD,170,00mi.know the fellow who bought it new,sat in his garage for three years, thought the engine was shot, however I added an addative she smoked and started purring, however still have some blow-by,love this machine, going to convert to bio-D soon as I get this beauty up to speed.Engine started rattling around the timeing guides, so I shut it down, I think another problem is it sat so long that the o ring on the bottom of the turbo got hard and it was causing fuel to blow by can anyone give some input on this problem?

As I suspected, someone out there had the right answer. Thank you all, especially rmarzman. To bring you all up to date, the car is a federal '84 (should have told you that in the first place) and the engine is a federal '85.
So - for clarification, I should be able to plug new engine in and leave theelectronic rack sensor unplugged? Easier than I thought - seller of '85 engine was cautioning me that there were electronic differences between the '84 and '85 IPs and I was just checking. By the way rmarzman - those charts you posted are priceless. Many thanks!! |

The other note, 1984 had a mid-model year change on tachometer setup. If you have a tach amplifier on your drivers side wheel well, then your tach runs through that. You would then leave the flywheel sensor unpluged or take it out and coverup the hole on the bellhousing plate. But if you don't have a tach amplifier, then it gets its RPM info from the flywheel sensor. You would just plug it into your existing setup. Quote:
