Im pretty handy with gas stuff but I know absolutely nothing about diesels.
We have a deer 2640 that I use 8-10 hours a year for Bushhogging.
Bought it about 10 years ago and it has been a good tractor. I have changed the hydraulic fluid and cleaned filters, found that a mid 80s jeep CJ alternator will fit with a simple pulley swap, and of course oil and air filter changes.
But a couple of days ago when Bushhogging, The tractor started bogging down. I switched to a lower gear and it continued to bog. Throttling up made no difference so I knew something was wrong. I started back towards the shop and it eventually died. It will crank right up and run for about three or four seconds and then die again.
I changed the fuel filter yesterday and the fuel looks good. It looks like I can also crack the return line on top of the pump the bleeding the air out of the pump itself, but from what I found online it sounds like that plastic ring might have given up the ghost and clogged the pump.
To local people I trust have said that it has to be calibrated so its not something I should attempt to do on my own.
So my first question is, is there a way for me to definitely determined that the injector pump is the problem? I would hate to take this thing off and take it somewhere for a rebuild only to find that it was something else causing the problem
Second question is, I understand these are times with the engine. Local diesel mech said that it should be keyed and that the gear stays in the engine so that as long as I dont pull the shaft out of the engine it will stay in time. Can anyone verify that on this particular model?
It also looks like there is a solid metal piece centrifugal clutch(?) that will replace the plastic ring that causes these problems. Does anyone have a link to that?
Ive done timing belt on my Honda cars, and I rebuild ATV engines down to the crank all the time, so Im not afraid of wrenches. I just like to do my research before I tear into something Im not familiar with.

Today's Featured Article - The Nuts and Bolts of Fasteners - Part 2 - by Curtis Von Fange. In our previous article we discussed capscrews, bolts, and nuts along with their relative hardness and thread sizes. In this segment we will finish up on our fasteners and then work with ways to keep them from loosening up in the field. Capscrews, bolts and nuts are not the only means of holding two parts together. When dealing with thinner metals like sheet tin, a long bolt and
