LUBRICATION 1300A
8-6 01-22-2019 Control # 051-08
Internal Cable Sheave Lubrication
A grease gun adapter is required to lubricate the internal
sheaves. The required needle grease gun fitting is:
• A 0.25 inch (6.35 mm) diameter nozzle grease gun tip
(National P/N 955045).
• Contact Manitowoc Crane Care to obtain this tip.
Lubrication of the extend and retract sheaves is as follows:
1. Extend the boom until the grease access holes on the
side of the 2
nd
and 3
rd
sections are lined up.
2. Lubricate the pin for the extend cable sheaves (18)
(Figure 8-1) until a small amount of grease extrudes
from the pin. From in front of the boom, look back
through the sheave case at the pin to determine the
amount of grease.
3. This position also aligns the access holes in the rear of
the 1
st
and 2
nd
sections for lubrication.
4. Lubricate the pins for the retract sheaves until a small
amount of grease extrudes from the sheave pins. From
in back of the boom, look up through the hoist mount at
the pins to determine the amount of grease.
Inner Boom Wear Pad Lubrication
Recommended lubricant is EP-3MG grease.
1. Fully extend and set the outriggers.
2. With the boom fully retracted, remove the access
plate (6) located on the top rear of the 1
st
section
(Figure 8-2).
3. Apply grease to the wear pads on the top of the 2
nd
section through the access holes (4) in the 1
st
section
with a grease gun (Figure 8-2).
