Once the clutch was installed, I then checked to ensure the crank & clutch where centered relative to the bellhousing/trans mounting flange. I then rotated the crank and the measurements again were well withing spec at only .002" out. This ensures the trans input shaft and the crank/clutch were in spec and aligned properly.


With the Tilton ST-246 clutch and the Tremec T56 part 11010, I had to trim the trans pilot tube from around the input shaft by 1/2".

Before trimming, here's the process I used to verify the measurements.

First, I measured the length of the pilot tube from the mounting face of the trans.... it's ~3"


Then I measured the distance from the bellhousing mount face to the top of the first clutch disc... it's ~2.3"


So the next step was to cut/shorten the pilot tube by 1/2" to ensure a gap from the end of the pilot tube to the clutch disc. Starting cut here with a cutoff wheel.


Pilot tube cut. I did some light filing to remove any burrs.


I'll be installing Tilton's Hydraulic Throw-out Bearing, starter and trans after the holiday and I'll post pics soon after.

Happy Thanksgiving to all..... we're off to your youngest sons house for the holiday in the Tampa FL area.
