A number of 1972 Sportsters were produced from November 1, 1971 to March 29, 1972 without the (3 position) stake operation performed on the rear left side fork bearing lock nut (47514-52). Bearing pre-load (which should be kept at 1-2 pounds) is controlled by the left and right (47515-52) bearing lock nuts. The affected VINs were (3A or 4A) 18748H2 to 33040H2. This safety defect prompted a recall of the affected bikes with the dealer being required to remove the rear fork for inspection and stake any of them that were done previously at a rate of $7 reimbursed labor and handling. 1)
Bearing Kit (47550-74) (replaced the single bearing part # 47521-52) contains 2 bearings which are 0.100“ narrower than the original bearing dims used in Sportsters up to February of 1974. The kit also contains a new pivot bolt nut (47512-74), bearing locknuts (L - 47514-74, R - 47515-74) and an outer spacer (47521-74) - clearanced for the new bearings. 8)
Caution: Parts must not be intermixed on a complete rear fork pivot shaft and bearing assembly. Correct bearing clearance and specified fork bearing preload cannot be obtained with intermixed parts. Correct bearing preload is essential for satisfactory operation and proper motorcycle handling. 9)
