Step-by-step instructions guide operators through removing and installing coarse shredder rollers on the HydraFiber Processing Unit. Recommended preparation includes allocating at least three hours, assigning two men, using leather gloves, and working from ladders or a forklift. The sequence covers opening doors and guards, removing belts, bushings, bearings, and plates, and carefully extracting the upper and lower rollers. Reinstallation steps detail setting the correct roller gap with 20-gauge sheet metal, tightening bearings and set-screws, torquing taper locks, reinstalling tensioners and belts, and fully securing all covers and doors.
Key Points
- Allocate minimally three hours, assign two men, use leather gloves, and work from ladders or a forklift; retain the shipping crate and install new set-screws.
- Follow a defined removal sequence including opening access doors, removing guards, hatch covers, belts, bushings, bearings, and the left-side rectangular plate before extracting upper and lower rollers.
- Reinstall rollers by inserting the lower and upper shafts, refitting the left plate and bearings, and tightening hardware while trapping carriage bolts between the roller and plate.
- Set a 0.035″ gap using 20-gauge sheet metal, center the rollers, apply thread lock to set-screws, torque taper locks to 54 then 108 in. lbs., reinstall the tensioner and belts, and secure all covers and doors.
