 Topic: Allis G, N62 Engine

Allis G, N62 Engine.
1. Tore the engine down and fond the source of knocking to be #1 and #4 rod bearings. Mains and #2 and #3 okay. Looks like oil has to go through rods 1 and 4 to get to 2 and 3 bearings. Oil channels are clear. Anyone have an explanation?
2. Checked on replacement governor assembly. Replacement offered is a "ball" type. My source says the "book" says interchangeable. Does anyone have first hand experience of replacing the weight type with the ball type on the Allis G?
Thanks,
Kent

I have a '48 G that has a knock when it is not under load. Was your knock all the time, or only under load, or no load ?
Thanks, Dusty

I have a ball type that came on a parts engine, Had a good weight type so didn't use it $10 plus shipping if you can use it.

Dusty,
My knock intensity varied at different RPMs. Knock could be "tuned" in or out by adjusting distributor timing at idle.
Engine knocks can be a little mysterious. They can vary from dull to sharp as well as rattle.
A knock under load could be just ignition timing or carbon build up. A duller sounding knock could be main bearings. Not that I want to tell you to go stick a hose in your ear, but that would be one way to try to locate the source of the knock. Put one end up to your ear and the other to various ares of the engine.
Timing. At low idle #1 should fire at Top Dead Center (TDC). When using a timing light, increasing the rpm should cause the timing mark to advance.

Sounds like something I'm willing to take a chance on.
You could call me at 712-243-9782. If no answer, leave a message. We have to screen out the politicians and telemarketers.

Dusty,
Sorry, I misread your post as a knock under load.
If you GOOGLE "Continental L-Head.pdf" you will find a downloadable service manual. Near the end of the service manual it has a troubleshooting section where knocks are addressed.
