Hydraulic release bearings for manual transmissions are so much easier on the leg than manual release, but you have to set it up in order for it to work correctly. We are installing an @AmericanPowertrain #hydramax bearing to our Gen V L83 with a #Tremec #TKX 5speed. In order to set it up, we have the engine on the bench (can be in the car or on the floor too), and we show you how to correctly measure the engine and transmission for air gap, then we make the necessary adjustments, recheck the measurements, and complete the job. In our case, we needed a spacer plate, as the air gap was a negative, meaning there was an interference between the bearing and the pressure plate. The space gave us the room we needed to dial in the air gap, making it a perfect fit. Spacer plates are not commonly needed, it just depends on the specific install.

American Powertrain recommends an air gap range between .100" and .200".
