With the number 5 cap not on the crank. I have .008. With the number 5 cap .003.
A little tight imo. What side would i need to sand and with which grit ?
I tried to outline this. Take a feeler gage and measure the clearance between the face of the bearing in the cap and the crank. It should measuure .008 as well if that's what you get without the cap. You can then proceed as follows.
1. You can blue each face of the bearing in the cap. pry the crank first forward and then aft as you rotate the crank. One face of the bearing is going to wear the bluing off. You can lap that face with 400 grit paper on a flat surface. When I'm describing this the bottom most part of the bearing is the part lowest when the motor is in operating position.
2. You can remove the dowel to free the cap movement to get more end play. If you remove the dowel make sure the hole isn't through to allow an oil leak. If the hole is through you can just drive the dowel down until it's flush with the block.
3. The face of the cap may not be square with block. Then you would only have to lap a small amount off of the bottom most part of the bearing to increase the clearance. You can verify this with a feeler gage. If it's tight on one side at the top and loose on the opposite side just lap the top of the tight side. When I'm refering to the bottom most part I'm talking about when the motor is in operating position.
