Fortunately there is another method called “spill cut off point timing” which we can use to time the injection pump. The procedure described below is for the 4 cylinder 23C engine as fitted to the Massey Ferguson 35, but the general process is the same for any engine. To time the injection pump when you don’t know any of the marks etc. These are basic instruction for the timing and installation of the Delphi (C.A.V., Lucas) DPA model pump. Since the procedure may vary depending on the engine please refer to the correct engine service manual for your engine. In an emergency however, if the timing marks are clearly marked on the engine and pump mounting flange, most.

Cav Dpa Timing Marks Off Table
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?
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.
Any thoughts or shared experience with CAV DPA Pumps.

I am questioning whether the pump is sticking in the automatic advanced mode, or whether it is generally too far advanced (but only firing early when hot)
At present it is on the factory timing marks. The engine is a Watermota Seapanther 33 yrs old.
Any ideas?
