A. Cut off the suction line flush with the junction
block (See Fig 7-a ). Enlarge the exposed junction
block hole by using a 37/64” drill (preferably
mounted in a milling machine or drill press to
ensure that the hole is round and properly sized).
Thread the hole with a 3/8” NPT tap. Properly
clean all chips and lube out of the hole. It is very
important that no debris be allowed to enter the
A/C compressor.
B. Following the graphic, thread the 3/8” NPT x 90
°
fitting into the A/C junction block. Tighten the
fitting so that it will point in the proper direction
when finished.
C. Take the cut-off section of A/C line (separated
from the junction block in step 1) and remove the
remaining muffler and tube starting where the
ferrule meets with the rubber portion of the line
(see
Figs. 7-b, 7-c, 7-d ). Discard muffler/steel
tube portion. Clean out the remaining rubber
hose/spring lock connector line. Slightly bend the
remaining muffler tube following the full scale
template on the next page.
D. Assemble the open end of the cut-off rubber hose
assembly onto the 90
°
junction block fitting. 1994-
95 models require a union and an extra length of
rubber A/C hose (supplied). Connect these pieces
as shown. Temporarily install the assembled A/C
line onto the vehicle. Allow the hoses to rotate so
that proper alignment is achieved. Mark the hose
rotation and remove the line assembly from the
vehicle.
E. Secure hose junction(s) with the supplied #10
hose clamps and permanently install the complete
A/C line onto the vehicle. Make sure that both
O-rings on the A/C line junction block are properly
located and that both of the springlock connectors
snap properly into place.
F. Extend the wires for the A/C compressor and A/C
line pressure sensor switch with the supplied wire
extensions and heat shrink sleeves.
