Oh yeah, that's right not supposed to post service letters on the site.

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 Specifically for the 337 announcing the new steel guide and superceded part number.

The pin you mentioned was also plastic. The new pins are metal. Unbelievable Cessna thought that was a good idea.

I'm interested to read this, but I cannot find it anywhere, even on the Cessna Support docs directory page. Its as if it never existed.

If anyone can point to where this Service letter can be found, it would be greatly appreciated.

Hi Mark,
You can find all the publications on Textron Aviation's Service Information website. It is free to get access to it, but if I remember, you have to sign some documents, etc, to get set up with a user and password. If you already have access to this, don't search for the exact document number, just type in ME84, and you will get a list of all the ME84 letters, etc, and it will be there.

I have an account, but it says "Not authorized to Subscribe to Publications", then it asks me for a customer number.

Way too complicated. I never did see it.

Or, I found it through Google.

Try this link for all the service bulletins. This is for my serial number, but if you change the end of the link to your serial number then you will get your listing:

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.

JAG · #11 10-18-20, 01:31 PM

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?

JAG · #13 10-18-20, 01:44 PM

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".
