Some information on the D15
First look as it Goes on the trailer
Getting chained down for transport
Tractor number above, engine number below
TS-500 Loader IE-1087-AC and MARK-IV 1A-934-AC Backhoe
How it looked on the trailer, loader and backhoe removed for now
Pushed into the shed and loose juice added through each spark plug hole
While the penetrating oil is soaking in the stuck engine I pulled the distributor and cleaned it
With rocker arm cover removed it looks quite clean
First look under the head, number 1 cylinder is full of water with the added oil floating on top
With water ladled out, wiped clean, and honed it doesn't look too bad but it is stuck tight
Gentle persuasion with a shaped wood block and a dead blow hammer, and rocking tractor while in gear
It moved and with cleaning and honing while pistons are at their lowest it looks much better
What it looked like under the head
Some stuck exhaust valves so I removed them all for cleaning
Number 4 has seen some problems in the past
All cleaned up and lapped back to their respective seats
Lubed and cleaned it is ready to go back on
Mounted back on the block with a new head gasket
