Nosegear actuator

Where did you source the parts/repair

[wslade2]

Sent the cylinder to Cox Airparts in Wichita. They did the overhaul pins and everything and bench tested before sending back. I asked before sending my cylinder to them if they wanted the hook/pin mechanism to come with the cylinder and they said yes, to test it. Once it got there they advised about the pin issue. Although I sent it for a leak/overhaul, while they had it they updated the hook pin mechanism. Very happy with them.

I was suspicious about my plastic spring guide, that plastic was in such a critical area, and questioned it's age/integrity. Discovered the spring guide issue while combing old Cessna Pilots Association articles where John Frank wrote about it on cessna 210's. I then found service letter for 337's advising the updated steel spring guide.

What is the service letter number? We're not supposed to post copies of Cessna's SLs, but that doesn't mean we can't link to their site where they have them posted.

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 Specifically for the 337 announcing the new steel guide and superceded part number.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

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.
