awesb Posted February 7, 2022 Report Posted February 7, 2022 Hi All, I recently removed the front seats on my Mooney M20J. The seats had been stickling a little when I tried to slide them. This is a new to me Mooney and it appears the rails had not been cleaned in years. My question is: Should I lubricate the tracks after I clean the rails? If so, what type of lubricant is recommended?

PT20J Posted February 7, 2022 Report Posted February 7, 2022 Usually cleaning the rails and making sure the seat rollers are in good shape is enough. Mooneys sit on the ground about 5 deg nose up. If you get things too slick, you’ll roll down hill pretty fast when you unlatch the seat if you really want lube the rails, rubbing them with a block of paraffin wax works well. Skip 1 Quote

After cleaning the rollers you need to lubricate the bearing. I clean the roller with alcohol. I use LPS2 to lube the bearing. Edited February 7, 2022 by 1980Mooney Quote
kortopates Posted February 7, 2022 Report Posted February 7, 2022 check the Deldrin rollers on the seats if there not rolling well after cleaning up the rails. they do wear out but not expensive to replace and new ones should slide easily.Sent from my iPhone using Tapatalk Quote
A64Pilot Posted February 7, 2022 Report Posted February 7, 2022 Wax as was said or dry zipper lube, which is often pretty much wax. You don’t want t anything that can attract dirt as that will cause wear. 1 Quote
47U Posted February 7, 2022 Report Posted February 7, 2022 If your seat rails are funky, the holes for the seat lock pins might be funky, too. Clean them out with a toothpick and vacuum up the little plugs of crud you dig out. And now you’ll feel better knowing your seat pins are secure in the seat rail. 1 Quote
carusoam Posted February 7, 2022 Report Posted February 7, 2022 Expect wheels to not be working as expected… Delrin is the new material used for wheels… The old wheels were brittle and have a tendency to break… PP parroting the knowledgeable MSers above… While cleaning and lubricating… vac out the holes for the seat pins… -a- Quote
Utah20Gflyer Posted February 7, 2022 Report Posted February 7, 2022 I just replaced all my seat rollers. Sourced them from LASAR, cost was about 80 dollars for the 2 seats. Things roll much smoother now. 1 Quote

carusoam Posted February 8, 2022 Report Posted February 8, 2022 Thanks A64! Phenolic resin… a nice thermoset polymer often filled with brown paper…. They are used for low cost, moldable, machinable parts… They last about 30 years… often seen on old sail boats for blocks used for mechanical advantage… with good salt water resistance… My 65C shed some of its seat wheels, and was running on the axles… Took me a while to figure that out… Quote
A64Pilot Posted February 8, 2022 Report Posted February 8, 2022 (edited) Last comment, you really, really don’t want wheels that are broken or don’t slide etc., it wears the tracks, and I believe even if you can get new ones, they are a real pain to replace as in ($$$). I need to replace my wheels if Lasar has them Edited February 8, 2022 by A64Pilot Quote
Yetti Posted February 8, 2022 Report Posted February 8, 2022 A 1/4 drill bit turned with your hand will get the dirt out of the holes.. You can buy Derlin rod the right size. Getting the hole in the center was done with a jig and a mini horizontal mill Quote

That would if you were turning it down from larger size. Getting the center on a lathe is hard work. So if the rod is already to size you need to be accurate on you hole. Ya I started with the lathe first. Quote
