MENU MENU. All this has been discussed on another post regarding a black smoke issue that wasn’t getting any activity. I would refer to the post but IDK how to link it or identity it. It is recent. Boat makes WOT RPM easy, High Idle is also good, prop calc confirms results, Boost is within spec at 22+psi, tachometer is reading high used phototach. History is lacking.I would appreciate any information on the timing mark on the CAV pump that may help me save some work in pulling the gear case cover to look at the gear markings.Serial number is: 44239031The pump has been removed from the engine. There are scribe marks on the housing and gear case that line up.
Unknown history on injectors. This is the next item to verify after the injection pump timing is confirmed. Well, timing pin is sheared. It is not in the cam gear and I cannot find it in the front case. I don´t believe it was done on my watch, but not 100%.The engine was not at TDC when I took the front gear case off. So, I don´t know what I felt when I thought the pin dropped in.Also, CAV pump reading a “C” on the rotor, expected a “G”.

Perkins Diesel injection pump timing help??? Discussion in 'Large Equipment' started by 2000ssm6, Mar 26, 2008. That looks like a pita to take the timing cover off while the engine is still in the hoe. Replacing my fuel pump and need help finding timing marks for my Perkins Diesel 243.
I don´t understand this. I also couldn´t find any info on rotor markings for the CAV DPA pump. I´ll have to continue searching for this.Going to get new timing pin. I don´t think it is worth worrying about the old one messing up the front end as it could have been some time ago. Which is most likely.Any advice is welcomed. I am going to get this back together and chase up the injectors next. Part of me wants to pull the injection pump to have it looked at by a shop.
But, really don´t want to spend the money on a gut feeling. I can always return to it if the injectors don´t show any issues.D.
I'm with Willie, I've worked on many Ford tractors, and was even service manager at a Ford tractor dealer many moons ago, and I am reasonably certain if that's a Perkins, it didn't leave the Ford factory. Massey-Ferguson tractors had Perkins engines, but Ford built there own.The main thing we need to know to answer your question on a Ford is: which injector pump do you have? The easiest way to tell is to see if your injector lines are in a straight line on top of the pump or if they are in a circular pattern on the end. Without being certain, I'm guessing this is the type of CAV pump you have. Fairly simple to remove. There's a round timing gear cover plate on front of engine, remove that cover plate to access timing gear retainer bolt #24 and remove bolt.
At this point, note which hole in timing gear that dowel pin #23 is located in, mark that hole position with paint stick or something similar.Remove all fuel line connections. In some cases, pump can be removed while leaving injection lines still fitted to engine clamps, but in most cases they interfere with pump removal and therefore require removing injection line vibration clamps and removal from injectors, then injection lines can either be pulled out of the way or removed entirely.
Also, I think this vintage engine used a gravity flow fuel supply, be sure and turn off fuel supply to prevent supply line flow.Lastly, the pump is fitted to engine with three bolts #20 going into slotted holes in pump housing. Very important, prior to removal of bolts, make a punch mark on edge of slotted hole seen in illustration, then a matching alignment punch mark on plate that pump is fitted to.
That way you can re-install pump in exact location it was in prior to removal.Once you remove the three mounting bolts #20, pull pump from mounting. It may require screwing bolt #24 back into pump shaft a few threads and give head of bolt 24 a rap with a hammer to pop pump shaft loose from timing gear.
