May 7th
Today was a very decent day. The weather was very good, not too hot of cold. Was put in a pickup for service calls. Stop number one was a service on a 770 compact tractor. Not only was it a service, but the owner complained it would not crank and start. Replaced the battery and the engine cranks just fine but it would not start. After diagnosing the problem it turns out that the injection pump is bad and not allowing fuel to flow to the injectors. Did not have the tools on hand to pull the pump so back to the shop. At the shop I was diverted to a major nursery grower in our area to work on a 5500 utility tractor. Turns out that the SCV (selective control valve, valve that controls hydraulic fluid to the implement) was leaking where it attaches to the rockshaft housing (rockshaft is the mechanical device to raise or lower the three point implement). Had to remove the seat and dress panels in the cab to get to the SCV. Got it removed and found an o-ring was missing which is why it was leaking. I had rebuilt the rockshaft about 8 months ago and I guess I had forgot to put an o-ring in it or it dropped out when assembling it. Anyway, back to the nursery tomorrow to finish the job and then back to the 770 to pull the pump tomorrow.
