13. Lower the crawler, raise the live mast, and swing as
needed to engage the top connecting holes (13, View E)
in the crawler frame with the top connecting pins (14) on
the carbody.
14. Once the top connecting holes (13, View E) engage the
top connecting pins (14), continue to lower the crawler
until the crawler lugs (21) are just contacting the
carbody. The bottom connecting holes should now be
aligned with the crawler pins (11).
Keep tension on the lifting slings until step 15
is
performed. Do not allow the full weight of the crawler
to rest on the crawler lugs (21), or the crawler pins
(11) and the bottom connecting holes can be
damaged.
15. Using the remote control, engage the crawler pins (11,
View E).
16. Remove the collars (9, View E) from the storage lugs
(12) and install them on the crawlers pins (11) with hitch
pins (10).
17. Extend the self-erect cylinder so the lifting slings are
slack.
18. Disconnect the shackles (5, View B) from the lifting links
(6) on the crawler (2).
19. At the inboard lifting link (6, View A), move the hitch pin
(7) from the top holes (8) in the bracket to the bottom
holes in the bracket.
The inboard lifting link will interfere with platform
installation if this step is not performed.
20. Proceed as follows at the drive end of the crawler:
a. Connect five hydraulic hoses (15, View C) from the
crawler to five hydraulic couplers (16) on the
carbody.
Match the identification numbers on the hoses with
the identification numbers on the couplers for proper
connection.
b. Connect the electric cable (17, View C) from the
crawler to the electric cable (18) on the carbody.
21. At the front roller end of the crawler connect two
hydraulic hoses (19, View D) from the crawler to the
hydraulic couplers (20) on the carbody.
Match the identification numbers on the hoses with the
identification numbers on the couplers for proper
connection.
22. SLOWLY travel the crawler in either direction to center
the treads on the crawler frame.
23. Install the second crawler. See "Install Second Crawler"
