Visually inspect exposed universal joint cross journals and needle bearings in bearing plates. Look for
defects caused by lack of lubrication and physical damage. If corrosion, pitting, universal wear or missing
bearing needles is evident, the universal joint must be replaced.
Dry cleaning solvent P-D-680 (safety or Stoddard's solvent) is potentially dangerous. Avoid repeated
and prolonged breathing of vapors and skin contact with the liquid. Do not use near open flame,
arcing equipment or other ignition sources. Always wear eye protection and protective clothing. The
flash point of P-D-680 is 100 to 138 deg. F (30 to 59 deg. C).
Using dry cleaning solvent (item 10, Appendix E) and a brush, wash universal joint crosses and yokes.
Do not attempt to disassemble or wash bearing plates.
Death or serious injury could occur if compressed air is directed against the skin. Do not use
compressed air for cleaning or drying unless the pressure is/has been reduced to 30 psi (2.11
kg/cm2) or less. When working with compressed air always use chip guards, eye protection
and other personal protective equipment.
Apply a small amount of grease (16, Appendix E)
to each bearing plate needle bearing.
Install and test needle bearings on cross journals
as shown. The movement must be smooth and
If any component is failing, the complete universal
joint must be replaced.
Inspect yoke as described in para. 4-26.1.
