I found a great solution to the issue of not having enough transmission input shaft engagement in the pilot bearing. I bought an HK1522 (21mm OD, 15mm ID, 22mm long) drawn cup needle bearing and a 21mm OD, 15mm ID, 3mm width oil seal to keep the grease in the bearing and the dirt out. I got the seal and bearing from a local bearing supplier for about $7 each. The original pilot bearing is 16mm long with a built in oil seal which reduces the amount of the rolling element length to about 15mm. I took a piece of mild steel drilled it 20mm deep with an 11/16” bit bored it to 14mm deep about 20.95mm diameter (basically just a press fit for the bearing.) Turned a 45 deg. chamfer 4mm from the end of the bar stock to support the bearing inside the chamfer in the crank. I turned the diameter of the material to 0.25mm smaller than the flywheel bore which is around 35mm +-5mm (I don’t remember the actual size). I parted the bar stock off at 17mm long. This gives me 11mm of bearing engagement in the crank and 11mm in the bearing and seal retainer I made. The total input shaft support is about 14.5mm. I installed the oil seal with the numbers facing the bearing to prevent dust getting in the bearing. I have not had a chance to run my car after installing the new clutch but I sure this bearing setup will work great.
