duke Posted February 4, 2013 Report Posted February 4, 2013 G0t mine a few days ago---very pleased at the quality
rbridges Posted February 4, 2013 Report Posted February 4, 2013 The previous owner to my plane had them, so I bought them from him. I know they're for preload, but how are they used?
1964-M20E Posted February 4, 2013 Report Posted February 4, 2013 Rob You will need a dial indicating torque wrench with a memory needle I find is the best. They run $150 to $200 look in the service manual to get the torque range you need. A torsion bar torque wrench will work but you have to look at several things at one time to get r done. The click style wrenchs I have not figured out how to make them work for this.
Sabremech Posted February 5, 2013 Author Report Posted February 5, 2013 Here's a copy of the pages out of the maintenance manual describing the use of these tools.
Sabremech Posted February 7, 2013 Author Report Posted February 7, 2013 I just want to thank those customers who purchased these tools. I'd appreciate any feedback if you'd like to share it here. It's my goal to produce and sell quality tools at reasonable prices. Thanks again, David Staffeldt Vintage Airworks

FloridaMan Posted June 5, 2020 Report Posted June 5, 2020 @Sabremech are there dimensioned mechanical drawings for these anywhere? I could possibly do a production run of these.

I could possibly do a production run of these. I can see if I can get you a copy of my drawings. Not sure they will be 3D as I believe the parts were water or laser jet cut then welded. I’ll get back with you next week if ok?
Manual gear preload check Posted April 24, 2021 Report Posted April 24, 2021 I have a set of original Mooney manual gear preload tools if anyone is interested. $200 for both nose and main tools.

RJHank Posted August 13 Report Posted August 13 I had an original set of 8444 and 8442 tools that I had given to my I/A to check the downlock tension on my M20C during an annual check. When I got my plane back he gave me a different set of tools that had some of the paint wore off of them. To make a long story short, I went to do the check myself but the 8444 tool seemed to long for my gear. Do you have dimensions I could use to verify the authenticity of my tool? Inside length of where tool presses against landing gear to where the push up point is located? Basically the overall length of the tool. Thanks for any help. If you can, please send to rjhank@sbcglobal.net. Thanks.

KeithN92KD Posted 4 hours ago Report Posted 4 hours ago NEW BUILD of 8444/8442 tool We have available new skeletonized Aluminum gear preload tools. No rust, chipped paint and light. The torgue for preload on the vintage Mooney is called out as 280/130 max inlbs. That screamed overbuild at the original steel tool. See if you agree. $145.00 for the pair, free shipping in the States. Just trying to reduce the cost of keeping our old Mooney flying. Email keithn92kd@gmail.com
