Starting my Diesel conversion 2.2 into 87 190E body - Page 3 - PeachParts Mercedes-Benz Forum

Well, hopefully this should do it, the car is still up on stands under the hoist. I hope it is not needed to undo front mtr. mts. bolts etc. but it may be better if I do. What a foolish oversight!

Thanks

Adjustment end is supposed to be at the shifter. I forget which side the clip is supposed to be on the tranny lever, I believe it should be outside.

Well I undid all the mtg. bolts, cross member etc. lifted & moved engine and trans. into a position to connect shift linkage. Also had left out the poly urathane bushing in the trans. linkage plate that recieves the linkage arm. What a bear, I am still not sure which direction the linkage is supposed to be in and which direction the clips face once installed???? Can someone place a pic on here or explain this, it would save me the time and trial??? Thanks

am finalizing my conv. of a 1987 190E w/ a 1984 190D 2.2 dsl eng. Update on the parts I was seeking. I found a Gates water pump and replacement belt tensioner assy. w/bearing from "********" all shipped for around $55. Parts look excellent and bolt right up. Hopefully I can get this engine fired up this week. I have the exaust hooked up, need to connect coolant lines etc. and will be ready to start engine. Can anyone direct me to a current source for a vacuum system diagram for a 1984 190D and 87 190E, W201 vacuum system? I'm in desperate need of one, also I may be missing a vacuum modulator(?) for this to work. The item I'm refering to in the pic below is located just to the right of the coolant resivoir cap, this is what I don't have anywhere on my car. The 2nd pic is of a 190D that does not have this item as shown in the 1st pic. It may be mounted somewhere else on other models but I don't believe there is anything like this on my 87 190E? My engine setup looks identical to the 1st pic, what do I need??? Thanks

Well after some delays, had to order and wait on a few items to finalize the conversion, I'm down to brass tacks. I only get a couple hrs. aday to work on this project so it is taking a while to get there. I am in need of some expert advise. #1. I would desparately like to incorporate the original glow circuit into my conv. I hope someone can walk me thru this final stage. I'm posting pics of my 84 cars relay unit which I mounted inplace of the ignition module on the drv. sd. fender. I show the wire coming out of the glw. relay box and need to know where to tie into my 87 elec. sys. The large red on the right side of the pic is the main pwr. feed to the unit, the green goes to a temp sensor in the head, I don't know where or what the red w/blk wire is. Help! Also in the upper middle of the pics is the wires I believe go to the ignition sw, where and what are they for. How do I wire them into the sys.? #2. The second pic is of the IP, there are 2 shiny blk. hoses running I believe from the oil filter to a unit of some kind that has 2 what look like barb hose fittings. One is shown just above the eng. mnt. the other is to the left of the philips head screw (not below it ). Help!!!!!

I can't help with the wiring, but the hoses are for the fuel thermostat. Most people just remove/bypass the fuel thermostat and heater. You just need the hose from the tank going to the lift pump, and the hose from the filter housing going to the return line back to the tank. Everything else is not needed if you want to simplify things.....Rich

I'd ignore that one. Probably another sensor.

Brown is ground obviously, I don't recognize the other colors though. Black is probably the glow light output. The remaining two are ignition signal (probably can be spliced from the ezl) and the cranking signal which can be had from the fuel pump relay, or fusebox if you know what color it is.

"A" bunch:
⌀=4 mm, red - connect to X4/10 (wire connector), clamp 30/clamp 61 (Battery)

⌀=2.5, black/blue - to 1 glow plug
⌀=2.5, black/violet - to 2 glow plug
⌀=2.5, black/red - to 3 glow plug
⌀=2.5, black/yellow - to 4 glow plug

"B" bunch:
⌀=0.75 mm, brown - to ground, front left (near headlamp)

⌀=0.75 mm, black - to central electric box/fuse box, socket "S", clamp "6" (inner connection with socket "D", clamp "3" and from it to control lamp in instrument panel)
⌀=0.75 mm, violet - to central electric box/fuse box, socket "S", clamp "12"
⌀=0.75 mm, red/black - to central electric box/fuse box, socket "S", clamp "4"

Thanks so much for the pic diagram. Where can I get the book or source that this came from? Also I'm not sure what is meant here (probably can be spliced from the ezl) and the cranking signal which can be had from the fuel pump relay.? Did the original 190D 2.2 have a fuel lift pump, if so I may have to add that as I removed the gas fuel pump of the 190E.

2peej · #10 08-03-2012, 10:53 AM

Thanks for all the help so far, I found this dia. but I think it is in Germam. Can anyone interprut the items numbered in the box on the right?

And, no ezl for a 601 diesel, obviously.

aaa · #12 08-03-2012, 09:58 AM

The fuel pump relay, if you haven't removed it, has a pin for the cranking signal, which comes via a wire from the fuse box. The EZL unit, which you probably also removed as you appear to have a glow relay there now, would presumably also have an ignition-on wire coming from the fusebox as well.

If you can figure out the colors (those diagrams help, I can see a promising plan of action in there with the socket S deal), then you can just get those two from the source at the fusebox.

It's not a 190e?

2peej · #14 08-03-2012, 06:37 PM

This is a 1984 190D engine into a 1987 190E body. I remove the gas fuel pump and filter sys. So the IP was the sole pump on the 190D as in other small vehicle dsl. engines, Isuzu etc. ?

The fuel supply tube from the tank should go to a pre-filter (clear/white plastic inline), and then to the lift pump on the side of the IP. The fuel return line should go from the filter head to the hard line going back to the tank. You should put fuel hoses directly from the tank to the hard lines going to the engine bay (bypassing all the gas related equipment).
You will need to prime the system somehow (fill the filter with Diesel, use a mighty-vac with brake bleeder catch bottle to get fuel up to the lift pump).
