It's not a slop fit bearing. It's a slip fit bearing. Serves the same purpose as a press fit in this application but otherwise easily to remove. I'm sure one could lap it in it it makes em feel better. Js.I think KTD doesnt want the crank to spin Inside of the inner bearing race.
Slip fit is fine. I chucked the crankshafts in a lathe and used emery cloth to polish them so they just slipped on. Worked fine in 10,000+ rpm opens.See what I started! I guess its time to get out the machinists handbook.I would think a slip fit would be a hard push on maybe a tap with a wooden mallet. I would think a press fit would be at least a 25psi hydraulic push. Just guessing.
Thanks I believe you answered a question I was looking for answers for, can I update an old model 13 to a ball bearing cover, without changing cranks?More clearance for oil, dimpling can help, add'l oil hole on top of the bushing. All will help, but the simplest solution (and long term) is to replace the sidecover with a ball bearing one. Slip fit a bearing to the crank and you're good to go as much rpm and for as long as you desire.

You will need to turn down the PTO end to fit the bearing for the bearing sidecover. It will not fit unless you turn it down on a lathe or are real patient with a piece of sandpaper.

Sounds like I'll need to find a used crank that takes a pto bearing, or maybe just change to a bushing side cover with the four bolts for a torque converter backing plate.You will need to turn down the PTO end to fit the bearing for the bearing sidecover.

How much benefit do you think your bearing is if the crank slips on the inner bore?if the bearing is not press on it doing nothing
No, usually not. Some have a "dot" on the timing gear and you will not see it with the bearing in place. Other timing gears have a line that extends to the end of the teeth -- you may or may not see that mark with the ball bearing in place.I've never seen a one peice bearing assembly press fit on anything, other than the outer race being press fit into a case ,only tapered Timken bearings that use a separate press fit race, as used in an automotive axle application , can you even see the timing mark on the crank gear to time your cam with the bearing on the crank?
