Raise the intermediate mast until it engages the
outer mast at the top. Lower intermediate mast into
the outer mast and check running clearance.
When the column rollers are properly adjusted, they
should leave a slight paint scrape on the inside rails of
the outer mast and the outside rails of the intermediate
mast.
8. Apply a small amount of multi-purpose grease to
the contact areas of the mast.

cylinders to the top of the outer mast near the chain
anchors using pins (index 3) and cotter pins (index
4). Refer to Figure 16948. Install internal stops at
top of outer mast.

mediate mast with retaining rings (index 62). Refer
to Figure 16948. Install chain rollers into top of in-
termediate mast.

mast. Use hardwood blocks and block each mast
section 300 to 380 mm (12 to 15 in) apart. Connect
lift chains to top of outer mast, route through top of
intermediate mast and connect to bottom of inner
mast.
