Ed Picardi 09-26-2009 15:37:13 65.199.106.178 85773 Report to Moderator	I am rebuilding my pony motor for my D4 Cat, 1955. I removed the top half of the motor. The pistons and valves have a horizontal lie. Even with a valve compressor tool I cannot figure out how to get the valves out. I really do not want to remove the cam shaft. Any help on removing the valves from the pony motor? [Reply]   [Send Email]

The valves and pistons are horizontal. I would think there is something that needs to be disconnected at the base of the valve where the spring pushes against. It is not like an overhead cam. You cannot get to the top of the valve, the only access is from the side. Can the valves be removed without removing the camshaft?   [Reply]   [Send Email]

Often means destroying the valve spring but it probably needs replacing anyway.   [Reply]   [Send Email]

You compress the spring and remove the retainer locks after removal from the engine. Phil   [Reply]   [Send Email]

I figured it was that easy, but when I was pushing against 55 years of crud I didn"t want to push too hard. Thanks for your comeback, I really appreciate it. Any pearls on getting out the pistons?   [Reply]   [Send Email]
