BOM/MACHINE: 80465 DESCRIPTION: KIT, REPLACEMENT T3 40KW SCI8D5 DOC. LOCATION: Engineering Documents/Installation Procedures

PREPARED BY: ANFANI OKOSUN

Purpose: This document is used to show the technician how to install the airend supplied with the 80465 kit.

Necessary Tools: • (1) 7/16” Wrench

• (1) 3/4” Wrench

• (1) 1/2” Wrench

• Wire Cutters

• Shop Rag

• (1) 17 mm Wrench

• (1) 7/8” Wrench

• Oil Drain Pan

• Electrical Tape

• Belt Tension Gauge

Procedure: 1. Loosen and remove the (4) bolts from the belt guard using a 7/16” wrench. The location of the bolts

can be seen below, circled in red. Remove the belt guard and set it aside on the bench.

2. Use a 7/8” wrench to remove the cap and drain the oil from the compressor into an oil drain pan.

The compressor drain can be seen below, circled in red.

3. Ensure that a shop rag is available to clean up excess oil prior to beginning this step. Using a 7/8”

wrench, disconnect the compressor oil hoses, circled below in red. Set hoses aside in an oil drain

pan to collect drainage.

4. Completely unthread the (1) tensioner bolt with a ¾” wrench, shown below circled in red. Fully

release tension on the drive belt by shifting the compressor and slide plate forward.

5. Remove the drive belt, identified below with a red arrow, and set it aside on the bench.

6. Cut the wires connected to the solenoid, shown below circled in red, using a wire cutter. Identify

and tape back the wires with electrical tape.

7. Remove the (4) bolts fastening the compressor and slide plate to the frame with a 1/2” wrench.

8. Note: the airend assembly weighs approximately 80 lbs. Using lift assistance such as a crane, or aid

from another person, lift the airend together with the slide plate. Once the airend has been

removed, place it onto the bench and turn it 90 degrees onto its side. The bottom of the slide plate

should now be facing you for access.

9. Remove the bottom part of the slide plate. The tensioner bolt from step 4 should be completely

loose from the top plate.

10. Remove the (4) bolts holding airend in place, circled below in red, using a 17 mm wrench.

11. Remove the slide plate and set the old airend aside.

12. Using a 7/8” wrench, remove the hoses from the top and bottom of the oil cooler, circled below in

red.


pg. 7

13. Unplug the harness from the bottom of the oil cooler.

14. Remove the (4) 5/16” bolts, shown below circled in red, using a 1/2” wrench. Remove the oil cooler

and the surrounding shroud.

15. Set aside the cooler shroud and bring the cooler to a radiator shop to have it flushed/internally

cleaned with steam or heated/boiling water.

a. NOTE: THIS STEP MUST BE PERFORMED PRIOR TO RE-INSTALLATION OF

HOSES. FAILURE TO DO SO IS LIKELY TO CAUSE THE NEW COMPRESSOR

TO SEIZE

16. Reinstall the cleaned oil cooler and shroud by following steps 12-14 in reverse order. Be sure to use

the new set of hoses provided with the 80465 kit, with the 307452 attached to the top of the cooler

and the 307453 attached to the bottom of the cooler.

17. Perform steps 1-11 in reverse order to install the new airend.

18. When installing the new airend, ensure that the hoses are connected to the correct fittings. The

longer hose (307452), attached to the top of the cooler, should be connected to the leftmost fitting in

the below image, highlighted with a red circle. The shorter hose (307453), attached to the bottom of

the cooler, should be connected to the rightmost fitting, highlighted with a red arrow.

19. A new pulley must be installed on the airend per the manufacturer’s recommendations, found on the

taper lock bushing box. Ensure that the taper lock bushing is installed in the same location on the

shaft as the old airend.

20. Ensure that the belt is tensioned to the following specification: ¼ inches of deflection at

approximately 9.6 lbs.

21. Refill compressor oil to the correct level: ½ way up in the sight glass. Re-check compressor oil level

after running the machine.
