PTO Gear Train With MFWD
ADJUST PTO SHAFT BEARING END PLAY
1. With PTa shaft in vise, install dial indicator as shown.
2. Rotate bearing quill several times in each direction to seat roller bearings.
3. Pull bearing quill rearward and zero the dial indicator.
4. Push quill forward and note indicator reading.
5. Add or remove enough shims to provide 0.03 to 0.13 mm (0.001 to 0.005 in.) end play.
NOTE: Shims are available in nominal thicknesses of 0.08, 0.15,0.30 mm (0.0030.006, and 0.012 in.). Measure shims individually to assure accurate measurement.
6. Repeat Steps 1-5 until proper end play is obtained.
7. Remove dial indicator and tighten retaining plate-to-quill cap screws to 68 N·m (50 Ib-ft).
ASSEMBLE AND INSTALL PTO SHAFT
NOTE: 1. PTO shaft bearing end play adjustment must be made before proceeding with final assembly and installa tion.
2. Disregard references to magnetic disk, pin, and snap rings, if tractor is not equipped with INVESTIGA TOR" Warning System.
1. Install rear magnetic pick-up disk snap ring (A) with the gap in line with pin hole in shaft.
NOTE: Later model tractors have a 6.4 mm (0.250 in.) solid pin instead of a spring pin. Pin must be in hole in shaft to keep magnetic pick-up disk from turning on PTO shaft.
2. Install pin in shaft so that it protrudes 6.00 mm (0.236 in.) from 0.0. of shaft.
2A. Install magnetic pick-up disk (A) with slot (8) over pin in PTa shaft.
