Resurrection of a Deutz MAH 914, 1952? Lets see!

Hi Ian

First things first. put pictures as many as you can!

Shims: My 914 has 3*0,25mm (only after running you can identify the knock - the few more knocking aka too early, the more lacking of power)

Dumping fuel: with injector out, turn crank to TDC (You can put a comparator with stem in bore to measure distance versus fly angle) [couldnt find angle of fire Before TDC]. YOU CAN DO IT WITH VEGETAL OIL FIRST.

Steel washer? where?

Just my thoughts for now.

My injection pump had a steel washer along with shims behind it but the ring was badly bent and the shim paper falling apart.

Does your pump only have the 3*0.25mm shims between it and the face it mounts on? My flywheel has an F stamped on the rim indicating TDC and the manual states the injection point should be 15 degrees +/- 1 degree.


I'll get some pictures on here soon! This one is staying the natural patina so don't expect flashy paint jobs!

Hi Ian, Gentles

Lets see the IP cam lobe bump: go here: https://listerengine.com/smf/index.php?topic=9555.msg109890#msg109890

As you can see lobe lift is 10mm. Therefore (now go here: https://listerengine.com/smf/index.php?topic=9555.msg109994#msg109994)

You must see if the travel of plunger is too far (you can take off IP valve [with IP snugged in place] and with the comparator see how much the travel is). If no shims you can eventualy damage pump element and plunger.

And yes all shims are between IP tappet guide face and IP face. Caspici?

I put back all paper shims it had, but if I notice it must be fine tweaked ill make more of 0,25mm gasket paper.

About fancy painting it's just a matter of each country evaluation. Here if I present an engine restored with patina is only a piece of junk.

Remember those engines are low compression, therefore they need starter cigar.
