MAINTENANCE

HEAVY DUTY FINISHING MOWER PTO SHAFTS

MAINTENANCE: The cross journals and the shield bearings at both ends of the shaft should be greased every 8 hours. Use 1 or 2 pumps of high temperature grease. The cones on the outer PTO shield must be turned until the access holes line up with the grease nipple in the cross journals. The grease nipple for the shield bearings is on the bottom edge of the cone. The PTO shaft must be pulled apart to grease the cardan tubes. Put about 4 pumps of grease into the female or larger outer tube. Slide the two halves back together. The quick release collars on the ends of the PTO shaft should also be kept lubricated. The cardan tubes and the release collars should be greased about every 20 hours. Clean all grease fittings before injecting grease and immediately replace any damaged or missing grease fittings.

SERVICE: The two major service areas on the mower PTO shafts are the shielding and the cross journals. The outer guards are held on by a nylon shield bearing. The three round white tabs at the bottom edge of the shield cones must all be pushed in to pull the shield off the cardan yoke and tube assembly. To replace the outer guards, first fit the nylon shield bearing into the groove machined into the yoke. Slide on the outer guard till it snaps in. The tabs on the shield bearing must line up with grooves on the inside of the outer guard.

The cross journals must be removed using a press or a vise. Do not use a hammer. Cross journal replacement is done with the outer shield removed. Remove the snap rings at the ends of the cross journal before pressing out. The cups on the ends of the cross journal contain numerous needle bearings. If even one of these needle bearings falls over, you will not be able to assemble the cross journal. Check that the end yoke turns freely after replacing a cross journal. Adjust the spread on the end yoke if necessary to loosen up the turning.

The quick release collars on the ends of the PTO shaft are held on by a snap ring. A pin and spring are inside the collar. Repair immediately if the collar fails to hold the PTO shaft solidly in place.
