3. CARRIAGE MAINTENANCE
Refer to Figure 4-10. There are two large carriage rollers on each side of the carriage, and four small
guide rollers on the top. These rollers require lubrication on a periodic basis, dependant upon usage
and climate. Refer to the appropriate Mechanic Maintenance Checklist in the Maintenance chapter.
The large side rollers carry the weight of the travelling frame. They have grease fittings and must be
lubricated with Aeroshell #22, or equivalent.
The guide rollers can be lubricated by spraying a light grease (ZEP PLS, p/n 497C, Curtisol® Red
Grease p/n 88167, or equivalent) into the interior
of the roller.
