How to determine your "A" dimension using Hydraulic Bearing. TR-6060/T-45/TR-3650/MT-82. Also fits Transmission With Integrated Bellhousing.

This Measurement is for TR-6060/T-45/TR-3650/MT-82.
All Transmissions with Integrated Bellhousings.

Before starting the measurements to your "A" and "B" dimensions, please make sure you have the proper measuring equipement to take this precision measurement. Tape measure is not precise enough for this job. Please find/invest/rent a measuring device with at least a .00 decimal point measurement capability. This is an absolute critical requirement to get the correct measurement.

This chart is to help determine what series hydraulic bearing you need. Before you begin your measurement please make sure to have your entire clutch assembly installed on the back of the motor and torqued down to the factory specifications, this includes Flywheel, Disc,Pressure Plate,Block Plate (if used) and Bellhousing. 
This application should be measured with a straight edge across the fingers of the pressure plate to the backside of the engine block. This will be your “B” dimension. Then measure from the bellhousing flange that touches the block to the bearing compressed (With NO Fluid in the system). This will be your “A” dimension. Your “B” dimension should be .100″ to .150″  less than your “A” dimension. If your dimension is out of this range and depending on what bearing you have (1300 series) or (1400 series) you can either change the length of your piston (1300 Series) or make an adjustment to your adjustment screw (1400 Series(each full turn is .060″ of adjustment).
