See attached pic, does this end piece off of the cam on a 239 flathead have to come off to take the camshaft out of the engine? It turns with the cam and I am trying how to get the cam out. I realize it slides out forward but cannot find anywhere to pry it out or any way to start it moving.
The distributor gear is pressed onto the snout of the cam. The timing gear bolts to a flange on the face of the cam. Neither needs to be removed to pull the cam, but all the valves need to be out, all the lifters out, fuel pump pushrod removed, and pulling the oil pump out makes it easier.
Is the engine out of the truck? Flywheel removed? If so, there is a cover on the back face of the block covering the rear end of the cam. If all the above has been done, you can knock the cam forward with a wood dowel and hammer.
What's wrong with the cam? Or are you stripping the engine for a rebuild?
The engine was running well and all of a sudden it quit running. I took off the intake manifold and found the lifters not moving. and I gave them all a good shot of penetrating oil and it didn't help so I figured it was the cam and tore the engine apart to a point of taking the crank and cam out to mike them to see if that is the problem.
So are all the valves stuck open? If the lifters are rusted in their bores, you shouldn't be able to turn the crank without breaking something. It isn't uncommon for engines that have sat a long time to have stuck lifters and/or valves. Removing the heads and removing the valves will give you access to the lifters.
Are the teeth on the timing gear aluminum or fibre? I had a stock timing gear strip out once while driving and let me sit along the road. Symptom was the same - engine would crank, but lifters didn't move.
Remove the 4 bolts in the picture and check the timing gear. If it's stripped you don't need to remove the cam. Just replace the timing gear.
