560D timing marks

5 posts in this topic

I bought a 560D basket case that took 2 loads to get home and hasn't run for 2 years. Got the pump rebuilt and want to make sure I know where TDC is. I have no T or rivet for TDC, has R, A and 50 degree marks. Am I correct to think that TDC is 10 Degrees from the last retarded mark? Static timing marks line up when set to 3 degrees advanced.

Thanks, Steve

i am sure if you look closer or clean the pulley you will find 0 degrees on it. should be in the middle of the timing marks, as one way is advance and the other retard.just because the static marks are lined up does not mean anything unless you have the pointer set on 3 degrees.

That motor has to have no. 1 at TDC or it will be 180* off. What all marks do you have between A and R? I was thinking my 560D had a T for 0* but it has been a long while.

Just because the lines line up at 3* does not mean its timed right, you HAVE to find TDC on no. 1, much easier to do it right then have to time it twice.

You might be able to use chalk to color the pulley and wipe off the excess and still have chalk inside the engraved marks showing the marks you cant see to the eye.

Did you put a new governor ring inside the pump? You might be wasting your time if you didnt.

Thanks for the replys.

With glow plugs out and valve cover off, #1 valves both loose, #6 has one tight and the timing marks are at the pointer. I've already cleaned and chalked the area between the R and A. There are 50 degree marks between R an A, no T or 0 to be found. IT manual shows a T near the R (maybe 10 degrees) in a picture. Pump guy also thought 10 from last retarded mark. The pump and gear are both near the middle of their adjustments. Thanks, Steve

The timing marks should go from 10 degrees Retarded to 40 degrees Advanced. If all the timing marks are correct on the timing gears on the front of the engine and the dimples are matched on the pump drive shaft and the rotor in the pump you should be on the correct cylinder.
