The bolt holding on the fan and the bearing bolts are of particular importance. 10. DANGER: Always stop blower for servicing or unplugging. The PTO should be disengaged before dismounting from the tractor. - 3 50” & 60” Allied Snowblower OPERATING INSTRUCTIONS – cont’d. 11. CAUTION: Always check to see that both ends of the PTO shaft are securely attached as per instructions every time you are preparing to use the snowblower. 12 When replacing bearings or tightening a loose bearing collar, always tighten collar in the direction of shaft rotation using a center punch or a similar tool. 13. Shear Sprocket: The shear sprocket (#43) should be checked at the beginning of every season to make sure it will spin freely. With time the sprocket plate could corrode and seize which will not allow the shear bolt to break if something jams in the snowblower auger. Clean to loosen if necessary. - 4 50” & 60” Allied Snowblower 50" & 60" SNOWBLOWER ASSEMBLY INSTRUCTIONS 1. Mount the discharge spout (#2) using the spout clamp (#3) bolted to the spout ring on the snowblower. Lubricate the spout ring and clamp. NOTE: A hydraulic cylinder and hose kit to control the spout deflector is available as an option. 2. Hitch Assembly: With right and left hitch tubes (#5 & #6) turned as shown in drawing, slide them into the sleeves welded to the main body. These tubes are adjustable to four different positions. The correct position for each individual tractor will be determined when mounting the snowblower on the tractor. These tubes are connected to the snowblower with a 3/4" x 3 .” pin (#11) and a hairpin clip (#12). Bolt the left (#84) and the right (#85) hitch arms to the outside of the clevises on the hitch tubes using the lift pins (#9). NOTE: Pins should be turned to the outside. Do not tighten any hardware until assembly is complete. Join the top of the hitch arms by bolting a 1” O.D. x 2 .” spacer (#4) between the top plates using a .” x 4” bolt and lock nut through the lower outside holes. Bolt the hitch top bar (#86) between the same plates using the same bolt through the welded tube on the bar. Use the inside holes on the top plates for the top bar. The other end of the hitch top bar bolts to the top of the blower fan housing with a .” x 1 .” hex bolt, lock washer and hex nut. Use the same hole position as the hitch tubes. Tighten all hardware. A category 1 top link pin (#8) is fitted in the top holes of the hitch arm plates. This pin is used for standard three-point hitch only. The bushing in the lower holes is used for the quick hitch. 3. Hand Crank Assembly: (Standard) a) Bolt the crank mounting bracket (#16) to the top of the hitch using 3/8" x 1 .” hex bolts, lock washers and hex nuts. b) Insert the crank tube (#15) through the mount and through the bracket welded to the main housing. Lock the crank in place using a washer and roll pin on each side of the bracket. c) Thread the cable (#17) through the hole in the crank tube to even lengths and wrap around the tube to each side of the hole four turns in opposite directions. d) With the spout turned forward, fasten the cable to the bracket welded to the bottom of the spout using a .” cable clamp (#70). - 5 50” & 60” Allied Snowblower ASSEMBLY INSTRUCTIONS – cont’d. 4. Hydraulic Control Assembly: (option) a) Bolt the hydraulic swivel assembly (#21) to the back of the fan housing on the left side using .” x 1 .” hex bolts, lock washers and hex nuts. b) Bolt the cylinder mounting bracket (#23) to the back of the fan housing on the right side using the same size hex bolts. c) Turn the spout forward and the center of the swivel arm in line with the spout center. With the spout and swivel arm in this position, wrap the cable (#22) around the spout and clamp to both ends of the swivel arm and to the bracket welded to the bottom of the spout using 3/16" cable clamps (#20). d) Use a standard 8" stroke cylinder (20 1/4" min., 28 1/4" max. pin centers). 5. Mounting Blower on Tractor: a) Mount the blower on a tractor with a category 1 hitch. b) Using tape or a bright colored marking pen, mark on the outer shield the position where the shaft is completely pushed together and the position where you have a 4" overlap. Watch these marks when moving the blower through all possible operating angles to see that the PTO shaft stays within this range. c) With the engine on the tractor shut off, attach the PTO shaft. The tractor end has a standard 6-spline end with a spring loaded locking collar. The snowblower end has a clamp-style yoke with a .” keyway. Slide the yoke onto the gearbox shaft with a .” key supplied. Lock the yoke in place with the .” x 3” hex bolt and lock nut fitted through the groove in the gearbox shaft. After tightening the bolt, insert and tighten the 3/8” socket set screw supplied. CAUTION: Always check to see that both ends of the PTO shaft are securely attached every time the snowblower is used. This should always be done with the tractor engine off. d) Check that the ...
