This mod can be utilized on any Mooney but is much more than "just bolting on a set of stock 201 gear doors!" The "Low Profile" inner gear doors we utilize present far less drag when closed or retracted than the stock MSE/231 type "bubble doors". When installed on manual gear Mooneys, at our facility includes: welding an additional 4130 steel "beef up strap" on the "Johnson Bar," re-heat treating, re-bushing & repainting the J-bar, new stronger main torque tubes, new nose gear torque tubes. While this mod can be done to any manual gear Mooney, some may have their (worn) gear components rebuilt or tolerances brought "up to specs" prior to implementation. Price includes a complete re-rigging of gear.
Note: In some cases and on some models, new (optional) bell-cranks are needed.
