We received the 62-6001 piston from Fisch Racing Tech and removed the shim to end up with 1.5875” overall piston height.
Once installed, this gave us a .220” gap, that was perfectly in the recommended range. The specification for the HRB base with this 62-6001 piston for the Competition Clutch triple organic clutch is PN: 60-1210-NS (no shim).
With the clutch bearing gap set, our engine and transmission were ready to be installed.
On the chassis side, we had to remove the original clutch master cylinder from the firewall that is located next to the brake booster. The clutch master cylinder shares fluid with the brake master cylinder reservoir. We removed this hose and were ready to unbolt the clutch master from the firewall.
The stock clutch master cylinder has a 5/8” Bore (0.625”) and does not displace enough fluid for many aftermarket clutches. We used a ¾” Bore (0.75”) Tilton master cylinder and an adapter kit from Grannas Racing to ensure the pedal engagement and feel is ideal for our triple disc McLeod clutch.

This car is going to be amazing.
Any reason why you didn’t go with one of the Tilton twin disc options?
It was not available at the time and we are excited to see how this organic disc design and technology performs. It has the potential to have smooth engagement characteristics and excellent low-inertia response. Stay tuned for our review.
Hi guys i have a tilton hydraulic throwout bearing/slave cylinder and im using a Mcleod twin disk clutch and Tilton H2B flywheel. I went to bleed the system and the piston popped out without touching the the clutch. It has about 1mm gap with the piston fully extended. What can i do? Where can i get a spacer?
You are going to need to get a longer Tilton HRB piston and/or a threaded adjustment sleeve. Be sure to measure the gap and follow Tilton’s instructions for the fully compressed clearance requirements.
Sorry i forgot to mention its a Honda F20B mated to a B series transmission
