Lycoming push rod shroud tube spring install.

[Montreal]

Does anyone have tips for re-installing the pushrod shroud tube springs on Lycoming IO-360A1A? New seals and springs, difficult to engage spring with tube and seals installed. Attached photo of shroud spring. Thanks in advance.

It takes bad words and blood.

if you coat the seals with DC4 you can get them to snap in pointed up and them rotate them where you like. Put a little DC4 on the spring and tube and the spring will rotate into place easier. If you put a 6”  loop of lock wire through the hole, you can slide a screwdriver through the loop and have a good handle to pull on.

So true!

Had good luck setting them in place, then rotating the whole shroud with light taps on a flathead screwdriver on up against the protruding part on the outside of the shroud.

You can use a J-hook pic or a small diameter door hook

.040 safety wire doubled up. Then pull them with safety wire Pliers. 
The aluminum pushrod tube is super soft. You’ll puncture or damage the ends if you pry on them.
