XFAKTR ARB Twin Compressor/ARB Manifold Mount Kit
2007+ Toyota Tundra
Engine Bay Prep:
- Unbolt windshield washer reservoir and power steering reservoir bracket.
- Remove power steering reservoir from the factory bracket and set bracket aside. Do not disconnect the power steering fluid lines.
- Remove the clip that holds the factory harness to the radiator support.
- Re-route the factory harness along the top portion of the radiator support, bringing it up and out of the way, and fasten in place with zip tie.
1. Remove the factory metal bushings and rubber vibration isolators from the factory power steering bracket.
2. Install the rubber vibration isolators onto the XFAKTR power steering reservoir bracket. Install the factory metal bushings into the rubber isolators.
3. Install the XFAKTR power steering reservoir bracket onto the XFAKTR compressor mount using two carriage bolts, washers, and lock nuts. Tighten until the rubber begins to compress and the bracket and mount are inseparable by force. Do not over-tighten these nuts/bolts. Doing so will reduce the damping ability of the isolators.
4. Place the two elevator bolts (carriage bolts with large, circular heads) into the square slots from the bottom. It helps to hold them in place with tape.
1. Adjust the ARB air compressor’s outlet to its max towards a 45 degree angle using manufacturer’s instructions.
2. Install the ARB manifold’s supplied hose and fittings onto the ARB compressor as described in the manufacturer’s instructions. Leave the fittings finger tight for easy adjustment later in the installation.
3. Attach the wiring harness to the compressor.
1. Lower the compressor mount assembly into place and align with the three factory threaded bolt holes in the apron. Install the three flange bolts loosely to hold the mount in place.
2. Place the windshield washer fluid reservoir’s legs onto the two elevator bolts and install with washers and lock nuts loosely to hold the legs in place.
3. There is some play in the alignment of these holes and the holes in the compressor mount to allow adjustability for variations in dimensions from truck to truck. Generally it would be best to center the bolts in their slots and then tighten to 10 lb-ft. From there the mount can be adjusted if necessary. The flange bolts are serrated to lock them in place but blue Loc-Tite may be used as well.
4. Slide the power steering reservoir into the XFAKTR power steering reservoir bracket until it locks into place with the tensioning leg. Check for any unwanted movement. The reservoir should be firmly held in place and should not be able to be easily removed by hand. Be careful not to bend the bracket during this fitment process. Since the factory reservoir body is plastic and is subject to marring, manufacturing defects, variations in dimensions, etc., some adjustment of the tensioning leg may be needed to ensure a secure fit.
5. Perform a visual inspection of the clearances of the send/return lines from the power steering reservoir and the drive belt. There should be approximately 1/2” of minimum clearance. Check for any other hoses that may have moved during the relocation of the power steering reservoir and ensure there is no contact with the drive belt or interference of operation.
6. Before completely tightening the lock nuts, move the windshield washer reservoir to the passenger side as far as possible and keep tension on it while tightening the lock nuts. This will ensure the maximum clearance with the ARB compressor.
7. Lower the compressor with attached braided air hose and wiring harness into place and loosely fasten it to the compressor mount with the ARB-supplied bolts and washers. Either use both outside slots OR both inside slots to mount the compressor. Only two slots need to be used. The other two slots may be used for mounting additional aftermarket accessories such as relays, fuses, circuit breakers, etc.
8. This step may be easier with a helper. Adjust the height and rotational angle of the compressor on the mount while checking for contact in three critical areas: the air filter housing, the relocated factory harness, and the windshield washer reservoir. Once the compressor body is clear of these three locations (and also not making contact with anything else), tighten the mounting bolts to the manufacturer’s specified torque. If all positions have been exhausted and there is still contact between the windshield washer reservoir and the 90o air fitting, this issue can be corrected in the following step.
9. If necessary, additional clearance between the windshield washer fluid reservoir body and the ARB compressor body can be achieved. Slightly push the reservoir to the passenger side (until until there is no contact between the reservoir body and the ARB compressor/fitting) and hold in place. The two fastened legs on the reservoir are plastic and should allow plenty of extra clearance. Mark the position of the top mounting hole on the top mounting arm of the reservoir and drill a ¼” hole. Fasten the top mounting arm in place with the supplied flange bolt. At this point the mounting arm excess length may be trimmed if desired, but it is not necessary.
10. Double check that there is no contact with the body of the ARB compressor in the three critical areas: the relocated harness, the air filter housing, and the windshield washer reservoir. Double check that there is no other contact between the body of the ARB compressor and any other engine components. Double check there is no contact between the drive belt and any hoses, harnesses, etc.
11. Attach the ARB manifold to the compressor mount using the ARB-supplied nuts and bolts, and the included washers.
12. Attach the braided air hose to the manifold, tighten all air fittings, and complete the installation of the compressor according to the manufacturer’s instructions.
