Mil-Spec has stripped the fuel truck’s chassis all the way down. Following the removal of brake lines, running board mounting brackets, battery box, the radiator and its frame, the truck is now about as disassembled as it ever will be. The restoration team has sandblasted the frame to remove surface corrosion and has begun the process of rebuilding!

Presently, they are working on the transfer case. This essential drivetrain component mounts to the chassis roughly behind the cab and is responsible for transferring engine drive power from the gearbox to each of the vehicle’s three axles. The restoration team has disassembled, cleaned and inspected the unit. Finding scoring on the input flange yokes, they salvaged these parts by installing “speedi-sleeves” over the damaged sections to allow a proper fit. They have since reassembled the transfer case with new bearings, seals and freshly-fabricated gaskets.

Engine work has also begun. The team removed and inspected the intake and exhaust manifolds, finding a small crack which required welding repairs in the latter. Similarly, the engine’s heat riser, brake vacuum check and PCV valves were also removed, cleaned, inspected, reconditioned and reassembled. The engine’s internal workings also received attention. Mil-Spec’s mechanics detached the pistons from the connecting rods and removed the hub from the camshaft, delivering these components (along with the manifold assembly and engine block) to the machine shop for further work.

Interestingly, the dipstick tube fitting on the oil pan had cracked - no doubt from years of heavy use - so it had to be soldered back on. The starter linkage, oil pan, air filter casing, bell housing, flywheel cover, and rear motor mounts each recently received a new coat of paint as well - all ready to go back on the vehicle sometime soon!
