Gonna try one more filter change, on the 750 massey combine,, after NEW CORRECT turbo ,still no power , and requires ether to start ,, nuthin I do helps , and it is getting where it wont hardly pull itself ,,just acts like its starving for air or fuel,,or simplyh fueling wrong and ???,CAN anyone tell me where the flywheel or balancer pulley should be in tandem with the CAV pump ,, before I pull the injector pump ??
 
Did you check the air pipe? On our old 510 it got plugged up with corn shucks. Got through the pre cleaner.
 
YES ,,removed it ,, makes no difference whatsoever ,,Thanx Jim,,,Wonder what settings are on flywheel ????
 
Not sure about the history of this. Should start with bad turbo and no either. Have you had the injector pump tested? Sounds like a pump problem. It has been a long timen since I looked at one but I think there is an o-ring that can fail and cause this.
 
I had this once on my 750. After checking everything twice it ended up being air being sucked in at fuel filters.
Took them on and off 3 times before I finally got it.
 
Not sure on the 372, but most 354 were 22 or 28 BTDC on flywheel when letter F is at square edge of snap ring inside. Pump has a master wide spline to only go back one way anyhow. Just check the flange ear scribe line at the mount base and put it back the same way. Some later pumps did not have the snap ring aligned with the "F" anyway. With the pump off the drive and plate notches must align at TDC on # 1 compression. If that is set right the flange scribe line is all you need.
 
Hi Have you tried doing anything with the main fuel lift pump/ or blowing lines back to the tank. we got a 750 with a 372 in. it would not start after every stop with air in and needed to be bled every time. and started loosing power to at one point. first thing i found was dirt in the line somewhere. we blew the lines back to the tank and it was better on power, but still would not start with the air in the system.
so I took the lift pump apart after everything else simple I could think about. found a non return valve floating around in there. we put a new pump on and it started good after that. maybe one of those 2 valves has fallen out and the lift pumps not working correctly. thats a fair height that fuel goes up from the tank to the motor! so that may cause starving, and why the either works. The motor runs a bit and gets a shot of fuel up there quickly.

something else that happened once was the Murphy switch solenoid to cut the fuel of at the filters started goofing around with a bad internal contact, i guess yours has the same system. it needs constant good power in the solenoid. intermittent/low power will restrict flow and starve fuel to as it opens and closes fuel flow.I Put another on from a NH i parted and that never happened again.

It could be a rubber lines breaking up internally and restricting fuel flow with a chunk flapping up and down with flow movement or the piece is detached and stuck in a bend somewhere. I can't remember how much rubber lines on hours without going looking in the shed.
have had that happen on other equipment before and cause the symptoms you have with no power.

Hi I just talked to Dad about something I remembered him saying while I was working away. There may be a filter on the bottom of the fuel suction pipe in the bottom of the tank. he can't remember, I just looked at the parts page and it looks like there may be a filter on the end of the pipe. Maybe thats plugged to, all he remembers is cleaning the tank out, after more plugging problems a few years later.
We have owned this massey 14 years and I have to try think back to what happened. apart from the odd age/ fuel related breakdowns it's been a good machine for us.

The other thing i just thought is when we bleed the system through the injector pump we feed the fuel shut off solenoid with 12v so it opens and flows the fuel to the main pump when we pump the hand primer. sometimes to get it to fire up and bleed the pump we have to also crack an injector line and run it until it clears a bit. ours needs a pump rebuild it has an external leak on the element barrel. but it still runs good at the moment. More of a fire risk than anything at the moment. it needs doing!

When its a question of fuel delivery, I take a one or two gallon weed or bug pump sprayer. Make up a fitting and tube adaptor and put a shutoff inline on the sprayer hose. I keep my can in a plastic garbage bag after use to avoid dirt issues. Pump it up a few pounds and dry to start.
I know probably most would disagree, but it sounds like the timing is 180 degrees off. I have had this happen to me a ccuple times over the years. Might be woth a try with the double spline you can not miss.
 
There is a fine brass screen above the sediment bowl inside the fuel tank. It will get plugged with algae and other crud.

The field expedient way to fix it is to blow some air back unto the tank.

The right way is to pull out the sediment bowl, clean screen and tank.

A weak lift pump could be an issue also. 12V one installed down by the tank will help immensely, and make changing filters easy.
