MF 230 diesel---got it started today

Brought home a MF 230 a while back and the previous owner had passed away so it didn't run and nobody knew much about it. The fuel filter had a pinhole in it and was pretty nasty. Today I filled the filter with fresh diesel and started cranking. It took a while but after cracking a couple lines loose at the injector pump it took off and ran fine for a few minutes before it died.

While I was attempting to restart it I noticed some bubbles at the throttle shaft on the injector pump. The shaft seems a bit loose. Is this one of those things that could turn into a high $$$$$$$ repair?

I was happy to discover that the tach drive was functioning which might also mean the 1100 hrs on the meter might be correct.
 
The shaft repair is simple if you take your time! Clean everything
real well all around and above the pump and remove the
linkages. Now remove the two nuts on the top between the
throttle shaft and the strangler shaft, these will probably be
wired together., also remove the copper washers. and the levers
from the both shafts. Carefully lift the lid off the pump, BUT....tip
it up slightly first and look in and remember what position the
springs are in. unhook everything and push out the shafts and
replace the 'O' rings. rebuild it in reverse order, but remember to
fit the springs and linkage in the correct positions. Do not
overtighten the nuts on top as it is easy to wring the studs!!
Take loads of photos and even try to get one inside the pump
when you tip it up slightly.
Good luck....Sam
 
Thanks for the prompt reply. My I & T manual appears to be practically worthless regarding injector pumps.

When you refer to pump cover what would I be looking at? Something tells me you might be talking about a different style pump than what I have.
 
OK I stripped an old pump this morning to get you all some pics of how to cure this simple but messy problem.......
First pic...remove the tying wire and remove the two nuts on top
2nd pic...remove the nuts and washers and levers from the
throttle and strangler shafts
3rd pic...you need to look in and upwards to see where the
spring is attached...be very careful as the spring can unhook.
(my camera had bother focusing)
4th pic....there are 3 holes on the linkage at each end, this is the
front end of the spring and my 135 type had the pin to connect
the spring in the top hole.
5th pic...and the spring in the hole closest to the shaft on the
back/lever end.
Carefully lower the lid back on to the pump making sure the stop
linkage is hooked in correctly( Front shaft)
Make sure you get a new gasket for the pump body to lid and
new sealing washers for the fixing studs and 4 new 'O' rings (2
per shaft) 6th pic.
That is about the best I can do for you from this side of the
Atlantic!

WOW that is fantastic. That looks to be within my skill levels. When I was first looking at the pump I thought that cover was bolted on from below and repairs would be tough.

Thanks Sam, you have been a great help. I've always liked the looks of these red and silver tractors but they were always out of my price range. A 1980 is really new by my standards.

In case you missed it THANKS!!!!
