Air Line Lubricator – (Point A) The levelwind motor is a piston
motor with a rotary valve that receives lubrication thru the air
stream via the in‐line air lubricator.The rate at which the

During normal operation moisture can collect in the motor
housing.This will be even more prevalent in cold temperature
environments where
there is a large deviation between the
operating temperature of the motor and the ambient air
temperature.This accumulated moisture should be drained
regularly (Point D) after the winch has been allowed to sit for a
period of time to allow the water to separate out from the oil.

ACME Screw – (Point F) The levelwind carriage is pushed and
pulled through its travel via the bronze ACME threaded nut
running on the stainless steel screw.Since, the screw thread is
open to the environment, Ram does not recommend using a
heavybearinggrease whichwouldquickly become contaminated
withdirtanddebris. Instead,routinelycleanthescrewandwitha
paint brush apply a light motor oil (SAE 30W) to the screw
threads.
This should be done on a routine basis particularly before
deployingorretrievinglongrunsofwirerope.
Guide Bars – (Point G) – The carriage slides on two hardened
guide bars with bronze bushings located in the carriage.These
bushingsreceivelubrication through two (2) grease zerks located
on the levelwind carriage.Guards will need to be removed to
accesstheselubricationpoints.
On a monthly basis, pump a quality bearing grease (8 to 10
pumps)througheachgreasezerk.Routinelypumpinggreaseinto
the bushings acts to replenish the lubricant as well as flush out
any contaminants.Depending on the amount of usage and the
environment, this process may need to be repeated during the
operationcycle.
Ram recommends using Shell Gadus V220 2 Grease.
