Assembly Instructions for Cylinder Assembly
Insert Roll Pin (8B) into Cylinder (8A) Pin Hole and Press Pin on Manual Press to Maintain Pin Projection of 2.5mm. See views below for the
1. proper placement.
Replacement of Vanes
Hold Motor rmly in hand, strike mallet on rotor spline to drive rotor (1) and rear endplate assembly out of front endplate (9). Remove front
1. endplate (with wave washer and bearing) and cylinder assembly from motor module.
2. Remove Vanes (2A) qty # 5 from rotor and using degreaser clean all surfaces of rotor and endplates. Make sure not to get degreaser in
bearing or it may be damaged.
3. Oil all surfaces of new vanes (qty # 5) with ingersoll rand # 10 oil. Place them one at a time in rotor (1) slots. Make sure to match vane prole
radius with rotor prole radius. See view below. Note: Motor will run without lubrication but oil is used for maximum vane life.
16601056_ed1 23
4. Mount Cylinder Assembly in above assembly. Align pin in rear endplate with pin hole in cylinder assembly. Note: Hold assembly in straight upward direction otherwise vanes will walk out.
5. Place Front Endplate (with Wave Washer and Bearing) assembly onto rotor shaft. Align roll pin (8b) in cylinder assembly with pin hole in front endplate.
6. Place Fixture 80187420 on top of motor, then press until bearing (6) is properly spaced.
Notes:
1. Make sure to clear adjustment screw (4) and roll pin (7b) in rear endplate assembly from pressing.
2. Bearing should be pressed at least 0.025mm below the surface of the end plate, and not exceeding 0.2mm. The front bearing press xture 80187420 provides this spacing.
Disassembly of Motor Module
Heat Adjustment Screw (4) screwed in the rear of motor with heat gun.
1.
Note: Adjustment Screw has loctite. Heat is used to break that bonding.
2. Hold Spline Adaptor in vice. Insert rotor splines into adaptor’s (80187396 / 80187404 / 80187412 depending on rotor teeth) spline.
16601056_ed1 25
3. Using 3mm Hex key, unscrew adjusting screw.
4. Hold Motor rmly in hand, strike mallet on rotor spline to drive rotor (1) and rear endplate assembly out of front endplate (9). Remove front endplate (with wave washer and bearing) and cylinder assembly from motor module.
5. Remove Vanes (2A) Qty # 5 from rotor and using degreaser clean all surfaces of rotor and endplate.
6. Remove rear endplate assembly (7) from rotor.
Note: It is not a hard press, so gently press out rotor with a pin<7mm from endplate.
Assembly Instructions for Motor Module
Note: Replacement of motor parts may change shut o operation of tool. We recommend ordering new pushrod (132017).
1. Completely clean rotor and cylinder with a degreaser agent, it may be necessary to use a light brush to clean rotor and pin with degreaser.
2. Place Wave washer (3) in front end plate (9) counter bore.
3. Place Bearing (6) over wave washer in front endplate counter bore.
4. Place above assembly in the counter bore of xture 80187420. Kidney slot side of front endplate must be upward.
Note: Fixture provides proper placement of front endplate and bearing. Bearing must be pressed a minimum of 0.025mm below front
endplate surface after nal motor spacing adjustment. Heat build up and bearing failure may occur if not properly spaced.
5. Place Rotor onto front endplate bore. Hold xture 80187370 in manual press and press rotor in front endplate.
16601056_ed1 27
6. Oil all surfaces of new vanes (Qty # 5) with Ingersoll Rand # 10 oil. Place them one at a time in rotor (1). Make sure to match vane prole radius with prole radius of rotor.
Note: Motor will run without lubrication but oil is used for maximum vane life.
7. Slide Cylinder Assembly (8) over rotor and front endplate. Align roll pin (8b) in cylinder assembly with front endplate pin hole.
Note: Hold Assembly in straight upward direction otherwise vanes will walk out.
8. Put Rear Endplate Assembly onto rotor shaft. Align roll pin (7B) in rear endplate assembly with cylinder pin hole. Note: Counter Bore side of rear endplate assembly must be upward.
9. Grease Bearing (5) with Ingersoll Rand # 68 Grease and place onto Rotor Shaft and Rear Endplate Assembly counter Bore. Press Bearing Using Fixture 80187370 Until Assembly is tight and will not rotate. Note: Rear Endplate press xture 80187370 presses the bearing inner race. Pressing outer race may damage bearing.
