Looking for some input from you fellow nose wheel builders. The manual specifies "filing" the inner profile of the piston rod bearing (bushing) and shows a profile but provides not specifics as to final dimensions/fit. I could use some advice as to what clearance is desirable between piston and bushing, and how much taper is required. My initial effort has a straight bushing ID of 0.642 to 0.643 with just slight rounding of the two edges. There is more variation on the powder coated piston depending upon where measurements are taken along its length; OD of 0.634 to 0.640
So 0.002 to 0.009 inch clearance on the diameter.
Any thoughts and experience with this?
