Ford 4000 Timing Question

[Brutus45]

Looking for some guidance on how to make sure I did not skip a tooth on my cav pump gears. I have the pump removed and have read it is difficult but possible to skip teeth with these gears,so how do you check it to make sure that Didn't happen? So I see a dot on each gear,do I just need to rotate to top dead center and dots should be aligned? How would I turn engine to do this and is it ok with cav pump off. Thanks

Did you just remove the pump, or did you remove the timing gear on the front of the engine? If you only removed the pump, then the dowel on the front of the pump will only fit into the hole in the timing gear one way and timing shouldn't be an issue.

Should be impossible to skip gear teeth with those timing gears. Try it, you shouldn't be able to do it.

I think it can be done but will mark it and try it. I would like to turn the gears and make sure dot on pump drive gear matches up with mating gear before I put together. The tractor was running ok but when idling rpm would slowly start dropping or increasing. When going up a hill or running the tiller rpm would drop and I would have to manually throttle up to compensate. When lift tiller out of dirt would have to manually throttle down. Governor spring is correct. Could it be a clogged fuel return line? Which wouldn't explain the rpm increasing

I ve only had it happen once on my 4000 but the 5600 has done it a few times
The small screen in the back of the pump has gotten nearly stopped up
Had to remove the regulating valve assembly to clean it

I took the OP literally when he said skipped teeth.

 

[Brutus45]

I could not get it to skip a gear tooth, locked in good, so should not be the issue

 

[Brutus45]

Thanks. I have a new filter and all is cleaned. I checked all
fuel lines and blew out so those are clean. When I get pump
installed again I will see what happens this time. Hopefully it
will run under load as I am not sure what else to do

 

[Brutus45]

Where did you get those stabilizer links for the 3 point? I
need some of those

That s the back of a 4630 I was working on, I think those are factory but some of the aftermarket kits are similar
I put aftermarket on the 5600
