Valve assemblies and crankshaft oil plugs

I managed to get the valve assemblies cleaned up and everything checked with a micrometer. According to the reconditioning specs in my manual, the valves are all within spec. 3 split guides will need to be replaced as well as 1 spring.








It is interesting to note, all the split guide sets appear to be original FOMCO aside from x2 sets which I believe are reproductions. Of the 3 split guide sets that need to be replaced, 1 set is the repro set which has the worst wear out of all the guides.

Repro on left, FOMOCO on right





I decided to get creative to see if the springs were within spec. My rig looks alittle different than the one in the manual but garnered the results needed. Utilizing a long bolt and two nuts to lock against each other, then a large washer and another nut. The distance from the washer to end of bolt head is 2.125". The double nut and bolt head were ground down to fit within the spring.



With the gauge/bolt mounted in the drill press, the drill stop was set just as the gauge/bolt came into contact with the scale. This allowed the gauge/bolt to sit high enough for a spring to be slid in under it. Then compressed the spring, stopping with the drill stop as 2.125" was achieved. Resulting with the gauge/bolt just above the scale as to not add additional pressure/ weight to the scale.





The oil plugs in the block came out relatively easy. Using a propane torch, heated around the plug to 110F and the brass plug came right out with a hand driver. The steel plug required the heat and a slight rapp from an electric impact driver.

The crankshaft oil plugs proved to be a bit more of a challenge. First attempt was with just a slotted screw driver and a Cresent wrench on the shaft for leverage. Then some penetrant fluid, then some heat, then the impact, then I stopped before I mangled the slot to bad.....I ended up welding a nut to the plug. First 2 came out like butter, last 2 took a few attempts. The last one, I ended up having to weld a washer to the plug, then a nut to the washer in order to get the weld to stick.





Getting there, bit by bit. Now to track down some parts.
