IP timing adjust (turning) tool

FSM 07.1-114 has a procedure and describes a special tool (with a lousy pic) that allows you to rotate the IP and adjust the timing with the engine running. Has anyone built a similar tool on their own? The tool is NLA and was expensive (around $500) when it was available.

They show some amazing tools in the FSM, like the hypothetical (?) cylinder liner installation tool. Some did exist, but I wonder how many dealers actually bought them. Same thing in my old Mopar FSM's, all kinds of special tools that most resourceful people can find an easy way to do without.

Looks like a big open ended spanner to me.

Looks like the spanner anchors against 2 cylinder head bolts via an adjuster. I would like to know how that plate is attached to the head bolts. Pic in FSM is useless.

Original pictures

Do these help?





These are from the German FSM where the pictures are a bit clearer

I seen 3 show up on eBay with in the same Year but not single; always with other Tools.
I think it is expensive partly because part of it is left hand treaded or there is a Ball and Socket on one part.

I have a picture of the whole Tool Some where but all I could find is the one in the pictrue which is 1/2 of the complete tool.

The Heat Bolts fit in to the Holes and not shown there is a Clamp that clamps to the front of the Fuel Injection Pump and attaches to that slotted end to the Right of the Pic.

Either on our Forum or on Benzworked one of the Member made something that functioned the same.

When you move the Fuel Injection Pump it may be possible to tear the Gasket. If you plan to run Engine with the IP loose and use the Tool to rotate it that increases the chance of the Gasket tearing.

Those are good pics Stretch, does not show details of the piece that attaches to the head bolts but I had the right idea, I made these templates out of card board before looking at Diesel911's pic.

I think it is expensive because it is for a Mercedes!

If you oiled both sides of the gasket you could probably slide stuff around without breaking it

I was thinking the same thing. After loosening the IP mounting bolts, spray the gasket all round with penetrating oil and let it soak a while before turning the IP. I would hate to get an oil leak after a timing adjustment and have to pull the IP. A gasket is a bad design IMO, much better if it was an o-ring.

I *think* the newer engines use orings. You could order some rubber sheet from mcmaster and cut a slippy gasket for it

Or just try it with that spray on Hylomar gasket sealer - stops the leaks and "might" give you a bit of lubrication for the twisting.

I thought the point of this tool was to give you a little bit more control over the positioning of the IP - I don't think lubrication is going to change much.

This special tool reminds me of a helper tool I have for adjusting belt tension on alternator belts. It is essentially an extendible stick that you wedge between the alternator and the engine block. There's a screw thread in the "stick" that makes it extend or contract.

The lube is to unstick a possibly sticky gasket so it does not tear when turning the IP. Can you look up my IP and tell me if it uses a gasket or an o-ring between IP and block?
