These Steering shafts require some assembly and some trimming. Please follow these instructions
carefully and read completely before starting.
1. Thread the support bearing with the jam nut into the steering shaft support bracket until the shank is flush to the
frame side of the support bracket.
2. With the support bearing flush the curved side of the bracket should be pointing slightly toward the ground. Insert
the two 7/16 bracket bolts provided, thru two of the steering box mounting holes in the frame that are farthest
apart (bolt heads to the outside of the frame).
3. Thread the bolts into the bracket and hand tighten them. Fasten the column u-joint on to the upper steering shaft
(the upper shaft is the shaft that has a groove on the double d end).
4. Slide the upper shaft into the support bearing and attach the middle joint to it. Be sure the u-joint is phased 45
degrees out of phased.
5. Attach the top u-joint to the column. Attach the splined side of the lower shaft in the middle u-joint, but don’t
tighten, since this will need to be trimmed. (note: some kits have a different combination of joints. Determine
the correct order first)
6. Attach the rack and pinion u-joint on the steering gear, and determine how much will need to be trimmed from the
lower shaft.
7. Remove the shaft and trim to size. You will also need to put a groove in the shaft, like the one on top steering
shaft. You can do this with either a grinder or a file.
8. Reassemble the lower shaft, again making sure the u-joint are 45 degrees out of phase. Now that your shaft is
the right length, turn it to make sure it is smooth. You may have to thread the support either in or out if you feel a
bump or bind.
9. Once you feel your shaft is smooth tighten all fasteners. If this is a manual kit the lower u-joint that goes on the
pinion should be tightened to 40 ft. pounds.
