Regarding the spring guide: it is what was then titled "Multiengine Customer Care Service Information Letter" or "Multiengine Service Letter" dated Jan 13, 1984, number ME84-1. Specifically for the 337 announcing the new steel guide and superceded part number.

You'll probably have to have an account to access.

In a nutshell, the SL announces the availability of the new part, P/N 9882024-1, and says to install with reference to the service manual. List price is $68.14, $61.33 from Yingling.

Thanks, I was finally able to read it.

Can anyone speak to the difficulty level of installing the new part?

I scoured my logs and found no mention of this part, so I assume mine is still all plastic.

I did find out I have the upgraded fuel caps option installed though!

I highly recommend that if you are going thru the trouble to replace the spring cap, pull the entire actuator out and overhaul it.

Just so everyone is aware, the new (replacement pin) still has plastic, so you really have to look close before you go pulling this out if you see some white plastic. I have included photos of the new replacement pin - note the guide is still plastic.

Mark, it is not difficult to replace this, but it does involve removing the actuator and downlock. It is not tricky to rig on install, but takes some patience and is a tight area. You want to rig it perfectly too, on install.

Thanks Jeff - So what is the actual difference between the old and new part?

I am not sure the difference...when I rebuilt my actuator it had the metal pin with the plastic guide...I can only assume that maybe the pin was non-metallic before??? The SIL refers to this "Improved Actuator Spring guide" as "all steel construction" - but as you can see from the picture, it is definitely not "all steel".
