7 Steps to Ultimate Clutch Performance

  1. Use a 1988 or later input drum, identified by narrow snap ring groove and a 0.093'' 3-4 snap ring.
  2. Used only a 3-4 apply ring measuring 3.675'' +/- 0.005'' inches tall, commonly referenced as a Number 7 apply ring.  This stamped steel ring rests on top of the 3-4 piston.  The number '7' is stamped into the part for identification.  The OEM number is 8685043.
  3. Pre-soak all friction plates in automatic transmission fluid (ATF) prior to final assembly.
  4. First, install the special grooved apply plate (bottom) with the groove facing upward.  Do not attempt to install the narrow external spline friction plate, with "TOP" printed on it, into the machined groove.  Set it aside until Step 6.
  5. Install the friction plates, beginning with an external spline friction plate with friction material facing upward (away from the special grooved apply plate), then an internal spline friction plate with friction material facing upward, continue alternating until you  have installed seven external spline friction plates and seven internal spline friction plates.
  6. Important! Install the special external spline friction plate, identified by the narrow band of friction material, with the word "TOP" facing up.  This eternal spline plate does not look like any of the others.  It is critical to install this plate last.  Using it anywhere else in the pack will damage the clutch pack and void the warranty. NOTE:  Use of load release springs is optional.  Use of load release springs recommend for RPM above 5000.
  7. Finally, install the .145'' pressure plate provided, followed by the factory snap ring.  Clearance should be within the 0.050''-0.07'' range.  If not, install optional external spline shim to adjust clearance to 0.050''-0.070'' if necessary.  It is recommenced to check actual piston travel by placing a dial indicator on the backing plate and apply air to the third clutch feed.  If clearance is measured with feeler gauges, it is important to measure in two places at the same time, 180 degrees apart, for even loading of the pressure plate.  Failure to do so may cause incorrect end play reading.
