BENDIX SD-08-2414 manual Vehicle Preparation, Locating Bendix AD-IPAIR Dryer on the Vehicle

VEHICLE PREPARATION

1.Park the vehicle on a level surface and prevent movement by means other than the brakes.

2.Drain all reservoirs to 0 psi.

LOCATING BENDIX® AD-IP®AIR DRYER ON THE VEHICLE

1.The Bendix® AD-IP®air dryer must be mounted vertically (purge exhaust toward road surface) outside the engine compartment in an area of air flow while the vehicle is in motion. The AD-IP air dryer must not be exposed to direct wheel splash. If the air dryer is located directly behind the axle, a mud flap is required.

2.Maintain a minimum clearance of 12” between the air dryer and any potential heat source (e.g. vehicle exhaust). If this is not feasible, a heat shield must be used.

3.Make certain that adequate clearance from moving components (e.g. drive shaft, suspension, pitman arm, etc.) is provided.

4.Locate the air dryer on the vehicle so that a minimum of 1/2” clearance above the air dryer is available to allow desiccant cartridge removal. A minimum of 8” clearance below the air dryer is required to allow for desiccant cartridge bolt removal.

5.When choosing the mounting location for the AD-IP air dryer, note the discharge line length requirements stated under the heading Connecting the Air Lines, elsewhere in this manual.

Important Note: Under normal operating conditions, the maximum inlet air temperature for the AD-IP air dryer is 160 degrees Fahrenheit.

6.If possible, locate the AD-IP air dryer so that the purge exhaust does not expel contaminants on vehicle components. If this is not feasible, the purge exhaust may be redirected away from the vehicle by installing an optional special exhaust cover (piece no. 112609). The exhaust cover is available as a separate item from authorized Bendix® parts outlets. A 1” ID hose can be clamped on this special exhaust cover to allow the exhaust to be redirected.

MOUNTING THE AD-IP AIR DRYER

(Refer to Figure 8)

1.Install the lower mounting bracket (9) on the AD-IP air dryer. To accomplish this, it will be necessary to choose two, of the four available, mounting holes. To determine which two holes to utilize to attach the lower bracket, take into consideration the piping connections required to install the AD-IP air dryer and use those that will best position the unit for ease of installation. Utilizing the two cap screws (7) and washers (8), provided with the

AD-IP air dryer retrofit unit, attach the lower mounting bracket and torque to 300–360 in-lbs.

Note: The bracket mounting holes in the end cover may not be pre-tapped. In this case the mounting bolt will self-tap the holes on initial installation.

2.Saddle Bracket: Assemble the mounting strap (4) and saddle bracket (5) as illustrated, by utilizing the 5/16” cap screw (1) and sleeve nut (3) provided. Place the upper bracket strap in the end cover channel provided for it, then install the saddle bracket and secure the strap to the saddle bracket using the cap screw (1) and sleeve nut (3) provided. Install, but do not tighten the cap screw at this time. Orient the strap and saddle bracket (5) so that it is in a flat plane with the lower bracket. Torque the 5/16” nut to 60-100 in-lbs to tighten strap onto the shell.

Cable Bracket: Press the isolators (33) onto the upper bracket (31) as shown in Figure 10. Place the air dryer onto the upper bracket (31). Insert the cable assembly

(32)through the wing hole of the upper bracket (31), around the air dryer and then again through the bracket

(31)on the opposite wing hole. Note: some applications may require the button end of the cable be placed on the opposite wing.

When the air dryer is installed, make sure that there isn’t any interference between the cable ends and the vehicle mounting bracket. The cable assembly (32) should be placed in the end cover channel when routed around the air dryer.

Install the washer (35) and locknut (34) on the threaded end of the cable assembly (32), adjacent to the upper bracket wing hole. Tighten the locknut (34) until the washer (35) makes contact with the upper bracket (31). Do not torque the locknut (34) at this time.

Orient the cable assembly and upper bracket (31) so that it is in a flat plane with the lower bracket (9). This can be accomplished in one of two ways: either off, or on the vehicle as follows:

Off the vehicle: Place the air dryer assembly on a flat surface with the mounting brackets (1 & 9) down. Secure the brackets to the surface with C-clamps then tighten the cable locknut (34) to 140 in-lbs. Use a wrench on the hex side of the threaded end to prevent the cable from twisting.

On the vehicle: Bolt the brackets (1 & 9) to the vehicle air dryer bracket then tighten the cable locknut (34) to 140 in-lbs. Use a wrench on the hex side of the threaded end to prevent the cable from twisting.

3.Components and location used to mount the AD-IP air dryer on the vehicle must be rigid enough to minimize air dryer vibration.

4.Mount the air dryer on the vehicle using 3/8” bolts (grade 5 min.) and washers. Torque to 25 ft-lbs (300 in-lbs.)
