Specialized Indicator for IP Timing

[KDHBenz]

Diesel Timing Static Position Indicator
MB P/N: 617 589 08 21 00

Anyone interested in pooling some funds together to purchase and share this specialized tool useful in setting IP timing for the following engines:
601, 602.91 /.93 /.94 /.96, 603.91 /.93 / .96 /.97, 605, 606, 617.93 / .95

Samstag Sales has it for $329.95 +S/H...

I can't afford one for myself, so I thought this might be a better way for many of us. Let me know if there's an interest...

Thanks,
-Ken

I will loan mine out for 1 week@ $25. ! OF course I will need a deposit of $150 up front!

[KDHBenz]

I might just take you up on that...deposit and all...look for email from me...

Since you actually own the tool and are therefore obviously in the know... Is the procedure calling for the use of the position indicator inherently better than the Jim Mahaffey (MercedesList) method whereby one looks for fuel to well up in the bottom of the injector valve? I would suspect it would be easier and perhaps more accurate (although I am NOT knocking Jim's procedure)...

Thanks,

I recently had the pleasure of using the RIV lights to set timing on the SD, courtesy of one of our esteemed members.

By far, its a fabulous tool. Once you get the lower bolt released, you can set timing in about 10 minutes and it is guaranteed to be accurate within about 1/4 degree. It simply does not compare with the traditional method.

I was considering buying one and putting it in the rental pool. But, if MB Doc is willing to rent his for $25.00, that is definitely the way to go.

Brian,

Can you tell us a little more about the procedure using this tool. I have never even heard of it.

First, it only works on the newer IP's with the removable plug on the outside.

The IP needs to have the "notch" on the rotating shaft.

You remove the plug on the IP and thread the pickup of the RIV tool into the threaded hole being careful to engage the slot.

Connect the positive lead to the battery.

Set the engine at 15 ATDC on the power stroke.

Loosen all screws holding the IP and remove the hard lines.


There are two lights on the display of the RIV tool, "B" and "A". The "B" light is illuminated when the timing is early. Rotate the pump away from the engine until both lights are lit. If you go slightly too far, the "A" light will illuminate telling you the timing is late. Rotate the pump back towards the engine until both lights are on.

Carefully tighten the IP screws and install the hard lines.

Remove the pickup from the side of the IP and reinstall the plug.

Disconnect the cable to the battery.

You are done.

Sweet!

Did you notice that your timing was off by much?

How was the running and driving after setting it?

I learned of it from W126 Service library 07.1-111 procedure, which can be found here.

Can you you use a pulse injection adaptor to time these engines.That is what I use to time my truck.If so what is the timing supose to be set at.

Russell, sorry for the delay in response..........I've been away for most of the month.

I can't tell you the results of setting the injection timing as it was performed immediately after replacing the cylinder head, with completely new exhaust valves and new prechambers.

But, the timing was definitely late by about 3-4 degrees. I needed to rotate the pump up near the top of its range. The camshaft is late by 2.5 degrees on the crank using the marks on the cam tower.

You can, and it's even faster than the RIV tool. But, we need to get a proper correlation between the RIV tool and the pulse tool. I have the SD set exactly at 15°ATDC with the RIV tool and I need to contact Dieselnut14 and test the SD with the pulse injection system. Then there will be a direct correlation between the two methods.

Worked like a charm on my SDL. I'd probably buy one if they were cheaper. But you really don't have to time a diesel often.

Brian Carlton,

If you do get the corelation of the pulse indicator number for the correct timing, please put it in this thread. I've been thinking of a Ferret 765 with a 6mm. piezo adapter for Christmas.

How much will you give me for mine?
I could never get it to work on my 300SD, which likely has 300kmi on the injectors. I don't know if my injector pop pressure is too low or if the lines are too thick. I suspect the latter. I want to get a 5mm piezo pickup and try it on my OM602.

I'll get the correlation. Just need to make contact with Dieselnut14 and make a trip to Sea Cliff.
