Cav Dpa Timing Marks Off Skin
External timing marks. On a new engine the pumps are individualy fitted before the timing marks are scribed so they are a matched pair. If you have to fit a strange pump, and the engine doesn't perform, it is possible to reset these timing marks visualy. Jan 23, 2014 We’ve had a query about aligning the letter G against the circlip mark when timing the fuel injection pump on the 23C engine. Bob has followed the 23C Engine Rebuild DVD and notes that on the DVD it shows the circlip mark on the lower side of the clip gap. However, Bob’s tractor has the circlip mark on the hole above the circlip gap. The advantage of using my existing pump is that it can go direct back on timing marks but apparently, a new pump will require the timing to be reset. Advantage of getting my (possibly) fully serviced pump checked is that it should only require the seals changed as it has been lying in the garage of about 7 years. CAV, DPA, Injection Pump, Lucas.

I am in a dilemma over the best route forward regarding problems with my Ford 1600 diesel engine.
Last season, I had a problem when the engine started to make a horrendous knocking noise which was traced to one of the injectors having a small piece of steel stuck in it. The thought was that it may have been debris from the high pressure fuel lines so these were cleaned by blasting the insides with a connection to a pressure washer and dried with some acetone.
The engine ran perfectly for about 20 hours but just as we were getting the boat pulled out for the winter, the knocking noise came back indicating yet another injector misfiring.
Latest advice I have been given is that it may be the CAV DPA pump breaking up, one theory being the “bearing” starting to fail.
I have two alternatives thses being to get my existing pump stripped, the alternative being to get my spare DPA pump checked which was bought on Ebay as being fully serviced! but was it?

Any thoughts or shared experience with CAV DPA Pumps.

I have a CAV injector pump on my Massey Ferguson 235 a DPA 3233F360. I rebuilt a rebuild job where the previous mechanic did not replace the crank, oil pump or water pump. He undoubtably timed the engine according to his 'back yard' way of timing. The engine will run with starter fluid but I am having trouble getting the injector pump timed.
