1917 D45 rocker arms

Recommended Posts

Good luck with that, Bob.  Since you have a 1917 engine there are twice as many to deal with.  When I went through the valve train on my engine I used a small punch and pried them out.  I then made new caps out of Brass and put new felt in the cavities.  I think I got the felt from Hobby Lobby.  I used a leather punch to stamp the small pieces out.  The old felt pieces were really gummed up.

I had a heck of a time getting all mine out. I ended up removing the bushing and drilling the hole to accept a screw inserted from the bushing bore (photo) and a slide hammer to pull them. It was a bear. The pushrod was similar, just drilling through the cap and crappy old felt.

Obviously, I destroyed the caps. I made replacements of stainless steel and polished them before installation - they look like they were nickeled.

This is my spare engine that had sat in the forest,with no hood, for 40 years. The caps rere carp anyway.

After seeing the above solutions, I decided to make my own attempt.  I took a sheetmetal screw and ran it into the top oil hole.  The cap was pushed out with minimal damage to the cap.


I proceeded to remove all 24 caps with damage to about 4 that may require replacements.


Thanks for your ideas and encouragement.
