SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must include positive shut
off devices (either manual or automatic) near the end of the hoses
opposite the manifold gauge.
SERVICE COUPLERS
Never attempt to connect HFC-134a (R-134a) service couplers to an
CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers will
not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC-134a (R-134a) and speci-
fied lubricants have been used with the scale. If the scale controls
refrigerant flow electronically, the hose fitting must be 1/2²-16
ACME.
CALIBRATING ACR4 WEIGHT SCALE
Calibrate the scale every three months.
To calibrate the weight scale on the ACR4 :
1. PressShift/ResetandEnterat the same time.
2. Press8787.“A1” will be displayed.
3. Remove all weight from the scale.
4. Press0,thenpressEnter.“0.00” will be displayed and change to “A2”.
5. Place a known weight (dumbbell or similar weight), between 4.5 and 8.6 kg (10 and 19 lb) on the center of
the weight scale.
6. Enter the known weight using four digits. (Example 10 lb = 10.00, 10.5 lb = 10.50)
7. PressEnter— the display returns to the vacuum mode.
8. PressShift/ResetandEnterat the same time.
9. Press6— the known weight on the scale is displayed.
10. Remove the known weight from the scale. “0.00” will be displayed.
11 . P r e s sShift/Resetto return the ACR4 to the program mode.

2. When removing center bolt, hold clutch disc with clutch disc
wrench.
3. Remove the drive plate using the clutch disc puller.
4. Insert holder's three pins into the drive plate. Rotate the holder
clockwise to hook it onto the plate.
5. Tighten the center bolt to remove the drive plate.
6. While tightening the center bolt, insert a screwdriver between
two of the pins (as shown in the figure) to prevent rotation.
7. After removing the drive plate, remove the shims from either the
drive shaft or the drive plate.
8. Remove the snap ring using external snap ring pliers.
9. Remove the pulley assembly with the puller using a commer-
cially available pulley puller. (Position the center of the puller on
the end of the drive shaft)
For pressed pulleys:
To prevent deformation of the pulley groove, the puller claws
should be hooked under (not into) the pulley groove.
For machine lathed pulleys:
Align the pulley puller groove with the pulley groove, and then
remove the pulley assembly.
