MOLDBOARD & A-FRAME ASSEMBLY – 760TR, 860TR & 8600TR MODELS
6. Assemble the manifold. Each of the hose ports on
the manifold is covered with stretch wrap. Remove
the wrap and install adapter (B60403) in both
ports. Tighten fi ttings per torque chart.
NOTE: DO NOT let any foreign objects enter
into the open ports. The valves can become
contaminated and greatly hinder the snowplow's
performance. Torque to proper specifi cations.
NOTE: All of the hydraulic adapters can be found
packaged with the manifold assembly.
7.
Remove the A-frame cover to gain access to the
inside of the manifold compartment.
8. Attach the manifold to the A-frame using
cap screws (94498), washers (B61039), and
locknuts (91331).
NOTE: When handling the manifold, hold the
manifold at the sides of the block.
9. Connect one 3/8" x 36" hydraulic hose (49501) to
each adapter on the manifold. Route the hoses
out through the access holes located on the
sides of the A-frame, with one hose going out
each side. Be careful not to overtighten the hose
connections. Tighten hoses and fi ttings per torque
chart.
NOTE: Review the label on each hose for the
appropriate part number.
Lit. No. B64092, Rev. 09
10. Reinstall A-frame cover by aligning the holes in
the cover with those on the A-frame and securing
it with 3/8" x 1-1/2" cap screws and 3/8" washers.
11. Remove the dust cap from both of the
hydraulic angle cylinder ports and attach one
9/16" 90° adjustable elbow ORB adapter (40571)
to each port. Each adapter should be angled
toward the top of the moldboard. Connect one run
tee (B60539) to each elbow.
12. Connect one hydraulic hose from the A-frame
compartment to each angle cylinder. Be careful
not to overtighten the hose connections. Tighten
fi ttings and hoses per torque chart.
13. Connect one 3/8" x 115" hydraulic hose (B60473)
to each angle cylinder run tee. Be careful not to
overtighten the hose connections. Tighten fi ttings
and hoses per torque chart.
14. On each side of the blade, insert a cable through
the pivot bushing from the center, then pin the
cable onto the A-frame extensions. Slide the cable
through the spring, and add a washer (760TR and
860TR models only) and nut. Adjust the nuts on
the cable at full angle so that the wing stops just
touch the outside moldboard ribs.
NOTE: Too much adjustment will cause the wings
to stop before the snowplow is fully angled and
could stretch the cables.
Adjust the cables with the blade centered, then
angle the blade to see if the stops are touching.
Attach a jam nut to lock in the cable adjustment.
