Make sure all the passages are open in the filter housing, I had one where the tube from the top down to the pump was plugged with pieces of rust, blow it out with compressed air with the pump off.
Hi bboaz,
If my memory serves me right the injector shaft turns at half the speed of the engine so if the engine is doing 500 rpm the injector shaft dose 250 rpm and the fuel pump is geared of that so it will be going slower that that.
Some good boffins out there would be able to do the maths out there for this.
Regards
Hi Bboaz,
Dusted of the brain cells got out the abacus, totaled with the crayons added up the numbers an it roughly works out to 165 rpm if the engine is doing 500 rpm.
But I still coul be wrong.
Regards
Gear to housing clearance is also critical. If it's 0.004" or more it's considered worn out.
I don't have a 212 parts book to check but I have a 5j parts tractor that has a complete pump. Tractor was "running when parked", I don't no anything more than that about the condition of the pump. You're welcome to it .
ROME k/G Changed filters and cleaned tower. Didn't check the tube from the top of the tower to the pump. The motor is running so it is getting fuel, just not the pressure it needs to be. That will be something to check.
rax200 165 rpm That gives me something to work with. I have a mechanical tac-ometer. I will check my drill and see if I can copy that speed and see what pressure I get.
Old Magnet .004 clearance That is gear OD to housing ID i presume. I already have end clearance at a about .002.and that may be half worn out. I can see where the gears meshing with each other in the center could wear the gear smaller. Something to measure.
d2gary I would be very interested in your pump. If you do text send me a text at 573 433 92seven seven, or a private message and we can discuss the purchase of your pump. The motor in the 212 is the same as a D2. An extra pump will give me something to work with. I will take a picture of my pump to compare.
Thanks for everyone's input. I have numbers and maybe even another pump which might just solve the problem. I have a couple of D-6 Pumps. The housing where it bolts to the tower is different but the body and end cover are the same. Might be worth while to swap some parts to see what I can come up with. bboaz
Our channel highlights machines from the earliest Holt and Best track-type tractors, equipment from the start of Caterpillar in 1925, up to units built in the mid-1960s.
