Immelman Posted November 16, 2020 Author Report Posted November 16, 2020 Nukemzz, thank you so much. I like your heat shield solution. After looking at this further, its clear the lengths I have are wrong. The hoses snake past each other a couple of times, creating rub points, in an effort to run out the extra distance. I'll go forward with the lengths PHT has, since they match the PN's in the parts manual. 1 Quote

Where could I find this documented to show my shop? Thanks From the J manual, but the concept is the same for most Lord mounts. Clarence Quote

During my pre-buy IA noted one mount had a 1/4" split. After purchasing I ordered the set and IA said come get me when your ready to torque them, hours and I mean hours later he showed up to torque them and said bottom ones were in backwards. In his defense it was a top mount that was split so the bottoms were never looked at closely as they were all going to be replaced. I had taken photos of each mount prior and we went back and they were backwards before I started. They are much easier to install when they are facing to correct direction... 1 Quote
Nukemzzz Posted November 17, 2020 Report Posted November 17, 2020 So I just double checked my maintenance manual and it doesn’t mention mount orientation. July 1980 is the manual date. If they want these a certain way they should make it more obvious...or I need to get more recent maintenance manual? lol Quote
Nukemzzz Posted November 17, 2020 Report Posted November 17, 2020 And my parts manual doesn’t show it either. Quote
Guest Posted November 17, 2020 Report Posted November 17, 2020 Note the orientation of the mount in the first post. The mount under compression load normally has a ring in the rubber. Remember that older manuals had a certain amount of “assumed knowledge” As time went on they realized that more details need to be added. Clarence Quote
PT20J Posted November 17, 2020 Report Posted November 17, 2020 I don't know if the earlier models had shims, but with the M20J, you need to be careful to note the shim thickness/locations. If you just let them fall out on the hangar floor, you'll spend a lot of time getting the spinner to line up with the cowling. Skip Quote
carusoam Posted November 18, 2020 Report Posted November 18, 2020 Did somebody say something about orientation? -a- 3 Quote

Clarence I don’t doubt the top pair is backwards and we are going to flip them. Just wondering if my manual revision is too old and highlighting that some manuals don’t make this obvious which is a shame. Thanks for catching it. Quote
Guest Posted November 19, 2020 Report Posted November 19, 2020 Here is the link to the manual revision status page from Mooney’s website. Older legacy models haven’t seen a revision in decades, so yours may be current. https://cdn2.hubspot.net/hubfs/4147179/TECHNICAL PUBLICATIONS DOCUMENTS/Revision_Status_2019.pdf Clarence Quote

Mooney just embeds comments in the pdf files. But there is no revision control on this so you can never be sure you have the latest embedded comments unless you order a new one. Skip 1 Quote
