a. Remove the two Cap Screws (96719) that hold the
Rotary Lever Valve (M512LR) to the Ram.
b. Place Cross-Over Controller assembly behind Rotary
Lever Valve and reattach the Rotary Lever Valve using
the two Cap Screws.
c. Repeat steps a-b for second Ram.
2. Install Cross-Over Controller assembly (67449) for
RM051S-XXX-XX-B Ram (see Figures 6 & 7, page 5 & 6).
a. Remove the Cap Screws (96702170) and Washers
(96756) that are on the Ram. (Only needed on models

to length desired, approximately 48 inches (for Two Post
RAM). Can be shorter for Single Post RAM. Repeat for the
second Ram.
6. Using (94981-XXX-X) Tubing. Attach Tubing to pilot port
on top of Valve (H254PS) closest to Port #3 of the Low
Level Cuto. Run Tubing to (7) Branch Connector at port
#1 on (2) Valve. Cut to length and attach to the Branch
Connector. Approximant length of Tubing is 45 inches
(for Two Post RAM). Can be shorter for Single Post RAM.
Repeat for second Ram.
7. Using (94981-XXX-X) Tubing. Attach Tubing to pilot port
on top of Valve (H254PS) closest to Port #2 of the Low
Level Cuto. Run Tubing to (9) Male Elbow at port #2 on
(2) Valve. Cut to length and attach to the Male Elbow.
Approximant length of Tubing is 45 inches (for Two Post

ond Ram.
8. Using (94981-XXX-X) Tubing. Attach Tubing to (8) “Y”
Connector at pilot port closest to port #1 on (2) Valve on
the rst Ram. Run Tubing to (7) Branch Connector at pilot
port closest to port #3 on (2) Valve on the second Ram.
Cut to length and attach to the Branch Connector.
9 Using (94981-XXX-X) Tubing. Attach Tubing to (7) Branch
Connector at pilot port closest to port #3 on (2) Valve on
the rst Ram. Run Tubing to (8) “Y” Connector at pilot port
closest to port #1 on (2) Valve on the second Ram. Cut to
