DRIVE SHAFT MAINTENANCE
Every 500 operating hours, apply lubricant to the drive shaft’s zerk ttings at clutch and
blower ange U-joints, in hot climates (conditions above 95° F) lubricate the drive shaft
every 250 operating hours. (see Figure 10-1).
The drive shaft splines should also be lubricated with a bearing grease with an application
temperature range of -4° F to +347° F; the drive shaft manufacturer recommends Mobil
Delvac Xtreme Service™ grease as the lubricant.
