Now with the generator, water pump, and radiator installed.
She starts easy and runs smooth.
Thanks for the parts Lavoy.

Re: 1957 420C seized - photo journey
Starter, battery, carb, governor, re-installed. We wanted to start it up before we glued more components on, such as the radiator, etc. Then the distributor should be easy right?... Nope. This is where I learned the previous overhaul was done WRONG! The internal timing was previously 180' out. I gue...

Re: 1957 420C seized - photo journey
Big step was to mount the engine on the bell housing.
Two guys needed. One navigating the engine block onto the drive shaft, one flying the engine hoist altitude.
Looks good.

Re: 1957 420C seized - photo journey
Next step is to install the clutch disk and pressure plate.
I don't see how it can be done without the disk centering tool, but we had one.

Re: 1957 420C seized - photo journey
This is a pic of handy tools layed out on a truck hatch door.
Left to right: 420 guage, clutch disk centering tool (lopped of a scrapped drive shaft), bell housing mount bolts, with heads cut off, to align the engine as it is guided onto the bell housing.

Re: 1957 420C seized - photo journey
The oil-pan is on with it's new gasket. The next fun step is to line up the engine and flywheel to attach the flywheel. The orientation pin has to line up with a blind hole on the flywheel. For me, the trick was to set the flywheel, with the hole at 12:00 on a jack-ramp. Need a light touch on the en...

Re: 1957 420C seized - photo journey
A critical step is to set the internal timing of the engine. The crankshaft gear is aligned with the camshaft gear by mating the gears so the marks align. Then after the pistons are installed and everything torqued correctly, the oil pump is reinstalled so its distributor shaft is properly aligned t...

Re: 1957 420C seized - photo journey
This is the objective of the whole exercise! The new connecting-rod to crankshaft bearings being installed. They snap right in. Here is the cap half. Gotta keep it clean, no contamination allowed between the bearing and the cap surface. This is a rare beast indeed, the crankshaft journal was turned ...

Re: 1957 420C seized - photo journey
We reseated 3 resurfaced valves in the head.
The 4th valve, an intake valve, is new.

Re: 1957 420C seized - photo journey
I got every part I needed from Lavoy. Fast turnaround too. Thanks Lavoy. New pistons and new rings. We mounted the piston to connecting rod, then clamped the rod in a vice to hold the piston steady. The pics below describe placing rings on a piston. Sorry for the background clutter on some of the im...

Re: 1957 420C seized - photo journey
Update. Lavoy had everything except the main crank bearings. He actually found the 0.040 undersized rod bearings. But the main crank bearings were undamaged, so I'm gonna just stick them back in. Then next two weeks, I'll be scrubbing parts, etc. I expect I'll have everything by mid-September and wi...

Re: 1957 420C seized - photo journey
The crank itself is undamaged. I can re-use (don't wanna) the main bearings, but not the rod bearings. The replacement rod bearings need to be for an 0.040 inch undersized journal on the already-machined-once crank. I'm still looking for them. Got some possibilities in the works. One expensive optio...

Re: 1957 420C seized - photo journey
The bad news is that Lavoy informs me that the bearings for this turned-down crank are not available anymore.
Thinking about this.
Is it terminal?
Will I have to bury a 3 ton crawler because I can't find a 6 ounce part?
Stay tuned.

Re: 1957 420C seized - photo journey
#2's intake valve rod is too bent.
The resurfacing still leaves an unpolished mating surface.
Need to replace this valve.
