IP and lock tool for timing

I just got my ip lock tool so I can see if I have my timing correct.I own a 84 300d turbo 617 motor. 251k miles. the engine does run very well, I am just trying to fine tune the timing and then go on to those nozzels from colorado biodiesel to make this engine smooth as can be. All other things like valves adjustment are done and engine purged with diesel purge. my problem is I line up crank to 15 deg atdc and check the inspection hole for the tang on the gov wheel but do not see it and also to boot my new lock tool will not fit in thru the inspection hole so as to get it to lock in at approx. 15 degs.
Does any body have any suggestions, I bought my tool from sir tools, should I send it back? do I have the right tool # moo39. Also if I am to eyeball thru the inspection hole, what am I looking for, or can I feel it with a small screwdriver.I know a A-B light would be better but none are around that are affordable, any help from you guys would be greatly appreciated.

ip lock tool

the lock tool will let you know that the pump is at 15degs so that you can look at the crank and see if timing is correct or off a few degrees either way

The lock end has a small slot that looks like a screwdriver slot this fit over a tab in the injection pump. Its a little difficult at first to seat it. Does your lock screw in have the plunger that fits down in the pump? If not you probably have the wrong tool.

I recently purchased the lock tool, as well.

I have failed miserably in my attempts to engage the slot.

I have attempted to move the crankshaft, very slightly, all around 15ATDC, with the hope that the plunger will seat in the slot and stop the crank from rotating.

Does this ever happen? Or, can the slot just continue right on by the "V".

How can this tool be used by a single mechanic? Do you need one person underneath the vehicle to rotate the crank and another person to carefully watch the plunger?

Seems like a very difficult tool to use.

Any advice from those who have been successful is appreciated.

I just had mine out last week. It is very diificult to do it in the car. Removing the injectors will help. You can shine a light down the hole while someone turns the shaft. it wasn,t easy. The bolt came out of my pump while I was at a light. It took my a while before I found the problem . the pump had to be remove and I was very lucky there was no other damage. I set timing to 14 after and it now sounds sooooo quiet it makes me nervous.

Oh do not tighten the lock screw until your sure its engaged.

Why are you buying a tool...a slot in the end of a 3/8th dowel does a stirling job....difficult to locate the pump lock ? dunno why...

The factory tool uses a light/lamp to tell when the timing is set.

If you slowly rotate the engine via the crank bolt at 15 ATDC....with the tool properly orientated...it's a peice of....cake?

The pump will also let you time it the old fashioned way at 24 BTDC too.

Running the timing VERY slightly retarded,( 1 to 3 degrees.) will quiet the motor down a lot. Can you say ...LIMO ?

I never learned to trust the lockpin as a timing device and finally gave up on it as a principle tool. I ended up using a mirror and light to "eyeball" position the ridge in the center of the window, then popped the pin in for confirmation. I've since purchased the A-B light unit and now wonder what took me so long.

I'm running @ 13 degrees ATDC -- it sounds like a tractor.

It is possible that my pump is not of the model to accept the i-p lock tool. I took a closer look and, not only the plunger will not fit thru the hole, I did unscrew the 17mm plug, the plunger looks to long, if I could get thru the hole I could not srew in the plug that comes attached to it. I would like to eye ball it but I have had the pump turned several times and while looking in I do not see or feel this notch or tang that is supposed to be there.
Any help would be appreciated as I am not so sure it can be checked this way.

How does it run otherwise?
Power? Smoke? Clatta'?

word to the wise....For the OM617 there are two different tools...depending on if its the early or later style....I forget what the break point was for the old/new style..no I don't have one yet...I likely need one of each.

Someone please correct me if I am wrong, but I thought the timing tool is used to lock the IP when it is installed. To set or check the timing you use the AB light tool. When I set the timing on my 602 engine I just got the crank set to 15 ATDC and then turned the IP until the pointer was in the center of the hole. You would have to be extreamly careful using the IP lock tool while trying to turn the crank.

You do not need correction

Hey,
I failed miserably trying to get that tool to work also. It did not matter how I oriented that notch I just could not get it to work.
I wound up doing the drip method and that seemed to work fine.

Maybe someone can put that A-B light tool in the Tool Loaner Program?
Hint...Hint

I just put a '85 617 engine back together setting it at 15 degrees and positioning the injection pump with the tool and it worked out fine. I could feel the pin slip into place while turning the injection pump and then installing. I imagine it could be tricky trying to do it with the pump mounted and turning the crank.
