3. Installation Instructions
The following steps outline the general procedure for installing the seal kit. It is highly recommended to consult the official Torqmotor Service Manual SM1512 for detailed diagrams and specific model instructions. A visual exploded diagram, typically found in the service manual, is crucial for identifying component placement.
Note: A detailed exploded view diagram of the TF(MB) TG(ME) Torqmotor Seal Kits, similar to the one referenced in the original service manual, would typically be included here for visual guidance. This diagram illustrates the assembly sequence and component locations, showing the main motor body, shaft, various seals (back up ring, back up washer, shaft seal, body seal, commutator seal, dirt & water seal), and torque bolts. The diagram visually numbers components 1 through 6, corresponding to the parts list, and indicates specific assembly instructions.
Assembly Steps:
- Prepare the Bearing: Thoroughly coat or pack the bearing (Item 1 in the diagram) with the special grease supplied in the kit. This ensures proper lubrication and seating.
- Install Back Up Ring and Washer: Place the Back Up Ring (Item 1) and Back Up Washer (Item 2) into their respective positions as shown in the exploded diagram.
- Install Shaft Seals: Carefully install the five Shaft Seals (Item 3) onto the shaft.
- Install Body Seals: Position the six Body Seals (Item 4) into their grooves within the motor housing and other components.
- Install Commutator Seal: Assemble the Commutator Seal (Item 5) with its wedge side facing down into the commutator face. Ensure it is seated correctly.
- Install Dirt & Water Seal: Place the Dirt & Water Seal (Item 6) into its designated position to protect internal components from contaminants.
- Press Seal Flush: Press the seal flush to 0.02 inches below the housing face. This ensures proper sealing and prevents interference.
- Secure with Bolts: Reassemble the motor components and secure them using the seven torque bolts. Torque these bolts to 50 ± 5 ft-lbs [68 ± 7 N m]. Ensure even tightening to prevent distortion.
Refer to the service bulletin (050016) included in the kit for any critical updates or specific instructions related to your Torqmotor model.
4. Maintenance
Regular inspection of your Torqmotor's seals is crucial for preventing leaks and maintaining hydraulic system efficiency. Check for any signs of wear, cracking, or fluid leakage around the seal areas.
- Inspection Frequency: Inspect seals during routine hydraulic system checks or whenever performance issues are observed.
- Replacement: Replace seals immediately if any damage or leakage is detected. Using a fresh seal kit ensures optimal performance and prevents further damage to the motor.
- Lubrication: Ensure proper lubrication of moving parts as specified in the Torqmotor service manual.
5. Troubleshooting
If you encounter issues after installing the seal kit, consider the following common troubleshooting steps:
- Leakage:
- Verify all seals are correctly seated and not pinched during assembly.
- Ensure torque bolts are tightened to the specified 50 ± 5 ft-lbs [68 ± 7 N m].
- Check for any nicks or damage to the seals that may have occurred during installation.
- Reduced Performance:
- Confirm that all components, especially the commutator seal, are installed with correct orientation.
- Ensure no debris or foreign material is present within the motor assembly.
- Unusual Noise:
- Recheck all assembly steps, particularly bearing lubrication and component alignment.
If problems persist, consult a qualified hydraulic technician or refer to the comprehensive Torqmotor Service Manual SM1512.
