CUES SF973-INST Mud Master Kit Instructions

NOTES – UNLESS OTHERWISE SPECIFIED

Applying blue threadlike (440061) to all threaded fasteners is recommended.
Where brown thread sealant (445091) is specified, Teflon tape (440350) may be used as an alternative. Pressurizing the system and leak checking all hoses, PTC fittings, and NPT fittings is recommended.
Applying DeoxIT to electrical connections is recommended.
Dust caps should be applied to all receptacles that are not in use.
When plugging in cables/connectors, make sure to match the notch positions of the cable and receptacle before plugging in. Do not force cables into receptacles. Install connectors by threading them then pushing the connector in. Repeat until connections are snug.

Unplug the electric lift and the transmission.
Unplug all of the lights.
Remove the rear cover and cut the zip tie to remove the TM356 cable.
Reinstall the rear cover and apply dust caps and dummy plugs to the TM356 cable.
Hardware:
- 160553
- EC431
- EC3465
- MS398
The cables shown will not be needed in this configuration and should be kept for normal Mud Master operation.
Remove the electric lift from the Mud Master Chassis.
The electric lift will not be needed in this configuration. Retain hardware for future installation.
Install SF750 onto the Mud Master chassis as shown.
Mounting hardware:
- 4X – 101022
- 4x – 101740
The Rear View Camera (SF385) will now be mounted to the Light Array (SF380). Installation of the LiDAR (SF362) will also be covered.
Remove the two screws shown RVC.
Repeat for the 2 screws on the other side.
Set these 4 screws aside for reassembly.
RVC subassembly should now be removed from the mounting plate.
Remove the 3 screws shown (left) and set aside for reassembly.
Install the LiDAR onto the RVC (right) using the four M3 screws provided with the LiDAR. Hardware: 4X – HW952
Reinstall the intake/blower portion of the assembly using the three screws that were previously removed (left).
Install the mounting plate to SF380 using the five screws that were bagged and tagged with SF385 (right).
Note: When installing the LiDAR/RVC assembly, make sure to route the LiDAR cable as seen below.
Reinstall the RVC/blower subassembly to the mounting plate using the 4 screws that were previously removed.
The light array will now be mounted to the top half of the manual lift (SF749). This will allow for the remaining components to be mounted and cables and tubing to be routed.
Flip over both, the SF380 (with SF385 mounted) and SF749.
Align SF749 as shown.
Note: It may be necessary to loosen the mounting tabs on SF380.
Fix the SF749 to the light array using the four button head screws provided with SF380.
Assemble the regulator and fittings in the orientation shown below. All fittings should be tightly fastened. Use brown thread sealant (PN 445091) on all mating threads. Brown thread sealant has a 24 hour cure time and should be fully cured before supplying pressure through the fittings.
Using brown thread sealant, install the set screw provided with SF239 as shown (left).
Rotate the valve on SF252 counterclockwise until it is all the way “Closed”.
Screw the SF225 pressure tank into SF252.
Note: DO NOT open valve until thread sealant has cured.
Once brown thread sealant has cured, turn valve SF252 clockwise until it is all the way open and set SF239 regulator to 60 psi.
Note orientation of SF791.
Next SF251 will be mounted to SF791.
Mount SF251 to SF791.
Mounting Hardware:
- 2X – 101024
- 2X – 101736

from 90 ° Push To Connect (PTC) fittings and retain for future use. These should be installed when the unit isn’t being used.
Insert on end of the black tubing to the 90 ° PTC fitting that corresponds with the black tubing on the SF382.
Repeat for the blue and red tubing.
Make sure all tubing is properly mated with the PTC fittings.
Note: Don’t kink/pinch the tubing or cable when routing and securing with hose clamps.
Route the tubing and the yellow cable through the tubing clamp and secure with washer and screw.
Hardware:
- 1X – 121108
- 1X – 101736
- 1X – 101001
Route the black and red tubing through a tubing clamp and secure with a screw.
Hardware:
- 1X – 121104
- 1X – 101001
Route the black tubing around the back side of the regulator.
Cut the black tubing to an appropriate length for it be plugged into the 90° PTC fitting on the regulator.
Insert the end of the black tubing into the PTC fitting shown. Make sure the tubing is properly mated.
Note: Don’t kink/pinch the tubing.
Route the red tubing through SF791 as shown.
Route the red tubing through the two tube clamps on the side of SF380. Remove the set screw from the hole shown. Route the tube through a hose clamp and secure. Hardware: 1X – 121106, 1X – 101001.
Cut the red tubing to an appropriate length for it be plugged into the 90° PTC fitting on the regulator.
Insert the end of the red tubing into the PTC fitting shown. Make sure the tubing is properly mated.
Plug the LiDAR cable into the 12-pin receptacle shown.
