806 diesel update

[jhncp]

I finally figured out today the pump was
180 degrees off. It doesn't make any sense
why because the guy at the salvage yard
took it off with the drive housing and
when I took it off the dots at the end of
the shaft were line up and so if it's
taken off the gear it should be impossible
to not have right. So now the dots are
opposite and at 8 degrees btdc it's in the
exact same same spot as before and now
runs good. I figured the easiest way to
find out if it was on the compression
stroke is to take the oil pan off and look
at the cam shaft and I also wanted to look
in oil pan and looked pretty clean after
it was a run away motor from the governor
being stuck wide open. I wonder how many
rpms it was running to blow the muffler
off. I worked the linkage back and forth
many times and got it freed up. I also did
find the timing mark on the plate it was
very faint and you can verify it by
putting a small wire or Allen wrench into
the #1 hole on pump and you can see it
move past with a close eye. It was also
leaking fuel into the oil and I took the
seals out of the old drive housing and put
both of them in with the sealing side
facing the fuel. I took it for a spin down
the road and it's bad to the bone.

Yep BTDT . one of my OLD customers was plowing one warm spring evening and noticed his 806 was running HOT so he run it down to the milk house and turned the garden hose on the rad to wash it out with the tractor running Welp that COLD Spring wate was sure good to drink along with being COLD the 806 did not care for it and as he went to spray the right side the stream of water passed over the injection pump and it instantly seized and twisted the shaft . I get the call around 10 at night and we talked i told him why it happened and now he will need a pump . Well his Brother had a spare pump and he was like a 150 miles awayso Stan had his brother meet him half way and i went down the next morning and went to put it on and we fought that sob till i pulled the pump leaving the shaft in the tractor and the two DOT's lined up and i knew i was on TDC as i even pulled the valve cover to make sure i turned the pump so the dot in the pump was down and the shaft was up and it ran . That was the first one SOMEONE who ever worked on the PUMP before never scribbed the timing line that also made it way harder . O(ne never knows what someone else did before you got there.
