GENERAL CAUTION. Indicates information important to the proper operation of the equipment. Failure to observe may result in damage to the equipment.

Safety Precautions

LETHAL EXHAUST GAS: An internal

combustion engine discharges carbon monoxide, a poisonous, odorless, invisible gas. Death or serious illness may result if inhaled. Operate only in an area with proper ventilation. NEVER OPERATE IN A CONFINED AREA!

DANGEROUS FUELS: Use extreme caution when storing, handling and using fuels, as they are highly volatile and explosive in vapor state. Do not add fuel while engine is running. Stop and cool the engine before adding fuel. DO NOT SMOKE!

SAFETY GUARDS: It is the owner's responsibility to ensure that all guards and shields are in place and in working order.

IGNITION SYSTEMS: Breakerless, magneto, and battery ignition systems can cause severe electrical shocks. Avoid contacting these units or their wiring.

SAFE DRESS: Do not wear loose clothing, rings, wristwatches, etc. near machinery.

NOISE PROTECTION: Wear OSHA specified hearing protection devices.

EYE PROTECTION: Wear OSHA specified eye shields, safety glasses, and sweat bands.

FOOT PROTECTION: Wear OSHA specified steel-tipped safety shoes.

HEAD PROTECTION: Wear OSHA specified safety helmets.

DUST PROTECTION: Wear OSHA specified dust mask or respirator.

OPERATOR: Keep children and bystanders off and away from the equipment.

REFERENCES: For details on safety rules and regulations in the United States, contact your local Occupational Safety and Health Administration (OSHA) office. Equipment operated in other countries must be operated and serviced in accordance and compliance with any and all safety requirements of that country. The publication of these safety precautions is done for your information. MBW does not by the publication of these precautions, imply or in any way represent that these are the sum of all dangers present near MBW equipment. If you are operating MBW equipment, it is your responsibility to insure that such operation is in full accordance with all applicable safety requirements and codes. All requirements of the United States Federal Occupational Safety and Health Administration Act must be met when operated in areas that are under the jurisdiction of that United States Department.

2. Check alignment between bull gear and pinion. Gears must be parallel and in-line. Adjust drum location if necessary.

3. Bolt pillow blocks to frame using four bolts (#25), washers (#28 & #10), lockwashers (#27), and locknuts (#26).

4. Dump drum to check for binding. If binding is noticed, loosen bolts and realign pillow blocks.

5. Loosen intermediate shaft bolts and fine tune gear alignment if necessary. Set backlash in gears to

0.010” before tightening. NOTE: It may be necessary to re-adjust alignment of drum or engine so that both sheaves line up properly.

6. Reinstall the engine shroud.

Drum Bearing & Seals Replacement

Refer to Drum Assembly, page 14.

1. Remove mixing drum from mixer. See Drum Removal, page 10.

2. Loosen set screws and remove bull gear from main shaft. Use a puller if necessary.

3. Slide pillow blocks (#5) off of trunnions (#8).

4. Loosen set screw and remove locking collars from trunnion bearings (#4) by rotating the collars against the mixing direction of the paddles.

5. Remove four bolts (#19) and nuts (#22) holding each trunnion to the drum.

6. While supporting the main shaft, slide the trunnion off of each end.

7. Pull the triple seal kit (#9) out of the back side of each trunnion and discard.

8. Remove the retaining ring (#7) from each trunnion.

9. Remove the ball bearing and grease shield (steel washer) from the front side of each trunnion.

10. Inspect the bearings, and replace both if needed.

11. Thoroughly clean all grease from the trunnions.

12. Apply a medium strength thread locking compound to each outer bearing surface and reinstall the bearings and grease shields into the trunnions.

13. Reinstall the retaining rings.

14. Install new seal kits into the back side of each trunnion in the following order: Steel Washer, Soft Black Seal, Steel Washer, Soft Black Seal, Steel Washer, Hard Red Seal.

15. Slide trunnions onto each shaft end and bolt in place.

16. Slide bearing locking collar onto front shaft end and align shaft flush with collar.

17. Lock collar in place by driving in the mixing direction.

18. Tighten set screw using a medium strength thread locking compound and torque to 20 ft. lbs.

19. Repeat process for rear bearing.

20. Begin pumping grease into trunnion cavity while rotating main shaft back and forth. NOTE: If grease comes out through ball bearing seals, check that grease shield (steel washer) is installed and that bearing is fully seated in trunnion and cannot move.

21. Continue pumping grease until drum seals “pop out” into drum. Clean any excess grease from inside drum.

22. Slide pillow blocks onto trunnions and grease until a film of grease is seen all around the trunnion.

23. Reinstall the bull gear. Tighten set screws using a medium strength thread locking compound.

24. Reinstall mixing drum onto frame. See Drum Installation, page 10.

Engine Removal

Refer to Drivetrain Assembly, page 16.

1. Disengage mixer by moving engagement handle to “IDLE” position.

2. Disconnect wiring harness (#18) from engine by unscrewing ring terminal from engine and unplugging bullet connector.

3. Remove four bolts, washers, lockwashers, and nuts holding engine to frame.

4. Tilt engine and remove drive belts.

5. Lift engine off of frame.

Engine Installation

Refer to Drivetrain Assembly, page 16.

1. Set engine onto frame and line up with holes.

2. Disengage idler by moving engagement handle to “IDLE” position and install both drive belts.

3. Install four bolts, washers, lockwashers, and nuts to secure engine. Check for proper alignment between both sheaves (#4 & #5) with a straightedge before tightening hardware.

4. Connect wiring harness (#18) to engine by grounding the ring terminal to the engine and inserting the bullet connector into the splice terminal.
