Update on the Panhead!
I got the heads back from the shop and they are installed. I did some repairs on the rocker cover nuts. Gave it a few test runs and seem to have a problem with the getting enough oil in the front hydraulic lifters.
I have taken the oil pump apart, measured everything, messaged some mating surfaces and assembled it all back together. The pressure valve seemed a bit tight, so it got a nice polish too.
This it the setup I used to hold the shuttle for polishing. I turned a piece of wood, with a slight press fit.
The problem still exists. It is not severe or constant. I feel like there is some sort of restriction of the oil flow ,and am going to look at a couple of fittings that could be a problem. We will see!?
The primary drive on this bike came with a chain drive between the motor and clutch basket, it has a belt on it now. When the chain was on it, it was oiled through, passages in the motor cases, that are part of the crankcase ventilation ( breather system). The passage is also one of the crankcase bolt holes, and is 5/16" on one end and .553" on the other. The PO had used a washers and an acorn nut on each end and it would leak oil and not hold well. The acorn nut was crushing on washer in the .550" end. I made a O-ring bushing for the large end used copper washers under the nuts, to seal the holes.
This is a picture of the bushing.
This is the bushing in place, in the engine case, behind the primary belt cover.
Lots of projects going on, and the weather is getting nice. So it is a little time, switched between all the projects, at the moment. But things keep moving forward, and that is a good thing.
Just went on a memorial ride, up to the Mt Saint Helens, Johnson Ridge Observatory, in Washington state, with some 300-400 other bikes. The friend that puts this on, does it because, he and his dad where scheduled to be on watch, when something came up and they traded their watch time with another gentleman, the night the mountain blew. The gentlemen did not make it. 56 other people lost there lives that night. I had not moved to the state at that time, so I did not witness any of it.
More to come as I get things figured out!
