I am working on a 2.2L engine upgrade and a Ford T5 five speed transmission conversion and can't seem to find my notes on JH and Lotus pilot bearing sizes. I know the input shaft on the Ford transmission is 0.668 inches. I have measured the hole in the 2.2L crank I have and got 0.823 inches ID which would be the OD of the pilot bearing and got a depth of 0.720 inches. I know the length of the bearing can be a little longer than the 0.720" if need be. I was wondering if someone knows the dimension of the OD of the pilot bearing on a JH. I have a bearing that measures 17mm X 21mm X 17mm, but it is too loose in the crank and drops too far into the back of the crank. I suspect I need to move up to a 0.8281 inch OD for a pilot bearing to fit snug in the crank and I could move to a 18.5mm for the length of the bearing. The 17mm inside dimension seems to be just right for the Ford input shaft. I'm looking for any information to help confirm my measurements and to help me find a pilot bearing that I can use. I can use a brass bearing but I know it wont last as long as a needle bearing, so I was hoping to find a needle bearing that will work if I could just confirm the size of the OD of the JH bearing.
