 Topic: Time to rebuild the pump?
Posted: 24 Jul 2016 at 9:16pm |
|
Hello all. My 1982 6060 with 5003 hours is running a little rough. From idle speed to about 1500 rpm with no load it kind of skips and misses. It is worst when it is first started but still does it some even when warm. It runs fine at high RPM and under load. It is not a constant miss on one cylinder but more erratic like it is from different cylinders. The pump has never been gone through to my knowledge. Fuel filter has been changed, fuel is clean and fresh, tractor always stored inside. It started slightly doing this about 2 years ago and is slowly getting worse. I never removed an injector pump before so am a little nervous to do so. Is this where I should be looking for the problem or is it something else? Thanks.

Sounds just like my 220 did.It had a broken spring behind the delivery valve.Roosa pump.
Take the timing window off the pump and turn the engine by hand until the two marks are in line.One is fixed and the other turns with pump.Pump can be removed and replaced and be really close to "in time" as long as the engine is not turned and the marks are alingned when reinstalled.I am not familiar with the drive setup on that engine so not sure of removal procedure.My 220 slid back off drive shaft and shaft/gear stayed in engine.

It does sound like you are in need of an injection pump servicing. The 6060/6070/6080 pumps come off like Steve says, shaft can stay in the engine.

For some reason, those pumps are much more expensive new than others.
Send it to Ed!

So if the marks line up she's good to remove? What about intake or compression stroke? Is 5000 hours about when they need servicing? What is the best way to turn engine over to line the marks, doesn't seem to want to turn with the fan. Sorry for the ignorance but diesels are greek to me, always had gassers until this one.

The pump on that runs half of engine speed, so every time the lines in the pump line up, you will be on the #1 compression stroke. The crank turns 2 turns to one pump revolution. Turning them over can be challenging. I sometimes have success turning by the fan backwards, while pushing the belt tight. Always time one upon final assembly, by coming up on marks in normal direction of rotation though, to ensure the timing is right.
