Maintenance
10. Maintenance
For proper performance, the following maintenance steps
should be performed every 30,000 miles (48,280 km) or
three (3) months, whichever comes first.
Failure to inspect and maintain the
drawbar could result in separation of
the pintle hook and drawbar, which, if
not avoided, could result in death or
serious injury.
1. Clean and check for wear, damaged, or missing parts, and
a secure mount. Inspect for worn, damaged or missing
parts. Replace as required using only SAF-HOLLAND
Original Parts.
2. Inspect, in particular, the coupling contact area of the
drawbar. Inspect for any nicks, gouges and deformation,
which could interfere with or affect the safe use of
the drawbar. If cracks are visible, the drawbar MUST
be replaced.
3. Using calipers or SAF-HOLLAND Drawbar Gages
(Part No. TF-11887), measure the cross section of the
drawbar eye. Replace the complete product when wear
exceeds 0.125" (3.18 mm) from the original surface
profile. For original profile dimensions, refer to Section 3.
4. Inspect the housing welded connections for soundness
by referring to Section 2 in this manual. Inspect the
drawbar mounting for looseness. In addition to being
a safety hazard, a loose drawbar will cause excessive
“chucking” and rapid wear. If the drawbar is loose, check
the following:
Check for a proper gap between the end of the
drawbar shaft and the face of the lock nut by referring
to
Figure 10
in Section 8. Check the ends of the
rubber bushings for wear and check for excessive
vertical play.
If the rubber bushings are in good condition but the
distance between the end of the drawbar shaft and
the face of the lock nut is less than .50" (12.7 mm),
tighten the lock nut until there is a MINIMUM of
.50" (12.7 mm) between the end of the drawbar shaft
and the face of the lock nut. If the drawbar still feels
loose, another turn can be made.
If the rubber bushings look worn, they MUST be
replaced. If no rubber bushings are on hand, the
following steps can be made as a temporary fix until
new rubber bushings are made available:
a. Remove the cotter pin, lock nut, washer and
drawbar. Remove the rubber bushings and flip them
around so the worn outer edges are now inside
the housing.
b. Reinstall the drawbar, washer, lock nut and cotter
pin. (Refer to Section 8.) There must be a MINIMUM
distance of .62" (15.7 mm) between the end of the
drawbar shaft and the face of the lock nut.
