Trucking Factors (Updated with more sweetness and light)

This is the diesel injector pump on our Massey Ferguson 65. As you might be able to tell...it is covered in diesel.

The stopper valve in the back left of the rectangular cover is properly leaking (as opposed to merely weeping like other seals on the pump!) and the engine fan is blowing the leaked fuel over the exhaust manifold immediately behind it.

A rebuilt or new pump is somewhere between $800 and $1,100. A seal kit is $50 and the vane pump (right end of the pump) is another $50.

This new shed can not come soon enough. But I have so many other things to do instead of fixing a fu...tractor!!

Update: After watching a hour long video of an expert fully resealing this exact same pump...I bought the kit. And I got it from the guy that did the video as a bit of an anonymous thankyou.

It turned up in the mail this morning. Now the key to this is that Old Mate said that the o-rings that were causing me grief could be replaced without removing the pump from the tractor. All I had to do was remove the top cover. And that looked very doable under our dirt floored lean-to.

And it turned out to be true. However, this was the sort of fiddly tiny spanner work that easily brings out my inner Clarkson. Therefore, I had to pay special attention to maintaining due care and level temperament.

Such diligence paid off. The cover came off easily, I noted which holes the throttle spring was fitted to, I didn’t drop the tiny rivet into the pump body, I didn’t get dirt everywhere, I replaced the o-rings, I replaced the gasket, I lined everything up just so, I bolted it all back together, I bled the air out of the fuel system, I started the tractor, it ran perfectly, I stopped the tractor and it stopped... perfectly. I did a little happy dance and then it began to rain for the first time in nearly a month.
