MAINTENANCE

DRIVELINE LUBRICATION

Grease Fittings are located on the Cross Assembly of each U-Joint and on the telescoping tubes. Grease the

U-Joint after each 8 hours of use. FIGURE Mnt-0024. Do not force grease through the Needle Cup

Assemblies. Grease the telescoping tubes after every 8 hours use. Some PTO-to-Hitch connections may

necessitate cutting a hole in the shields to be able to align the Grease Fitting holes for lubrication. Lubricate

the shield bearings every 16 hours.

Mnt-0024

Make certain that the Driveline Integral Shields are free to telescope and rotate around the

Driveline without binding.
