MAINTENANCE

Anam Company recommends that you have adjustments  made by your local Ariens dealer. He has the tools and knowhow to properly perform these maintenance adjustments which may be required to keep the Sno-Thro operating at peak efficiency. The SnoThro is equipped with the finest quality engine obtainable. However, should servicing be required, it can be obtained from an Ariens dealer or an authorized engine manufacturer’s service station. Should you decide to make adjustments on your Sno-Thro yourself, Ariens recommends that you call your dealer for the answers to-any questions that might arise in performing this work.
SHEAR BOLT REPLACEMENT
Occasionally a small object may enter the collector and jam the rakes. When this occurs, the shear bolts securing the rakes to the shaft will break and allow the rake to turn freely on the shaft preventing damage to the gear drive. When this happens, turn off the engine, remove wire from spark plug, remove the broken shear bolt and replace with a new ARIENS shear bolit.
Use of any other type of shear bolt may result in severe damage to the machine, USE ONLY ARIENS SHEAR BOLTS FOR REPLACEMENT. Each time a shear bolt is replaced (and once each year) the rake should be rotated on the shaft and the shaft oiled. Oil shaft through shear bolt holes.The runneu 14 on each side of the blower housing are all adjustable to suit conditions. Raising or lowering the runners controls the distance the scraper is held above the surface being cleared. Runners are adjusted by loosening the two nuts securing each runner.
Move the runner to the desired position and retighten the nuts. Be sure to adjust both runners to the same height to keep blower housing level. Uneven runners make the. machine difficult to steer and will result in an uneven clearing job.
Adjustment of the runners is critical to good cleaning. If the ‘machine is to be used on a gravel surface; lower the runners so the blower will not pick up gravel then after the remaining gnow is packed down, the runners may be raised for close scraping. On smooth concrete or blacktopped surfaces, the runners may be raised so the scraper rests on the surface and scrapes clean. BLOWER CLUTCH ADJUSTMENT
The blower clutch is adjusted by connecting the spring on the clutch rod into the proper link on the clutch handle chain. Properly adjusted, the spring should be slightly extended with the clutch handle .down. This should occur without the attachment activator lever touching the hub. If the activator lever touches the hub, the blower belt idler pulley must be adjusted in the idler arm. Loosen the cap screw on the idler and move the idler IN TOWARD the belt. Readjust the spring in the chain for proper action. DRIVE DISC ADJUSTMENT
The only adjustment for the drive disc is made by adjusting the length of the traction clutch rod. With the clutch handle  in the full upright position and the clutch bracket downagainst the stop, tighten the allen screw in the rod adapter. To check the adjustment, push the SnoThro with the clutch handle up; it should roll freely. While pushing the Sno-Thro, slowly lower the clutch handle. The wheels should start to drag with the clutch handle approximately halfway down to the handlebar grip when properly set. If necessary, adjust the clutch rod in the rod adapter to secure this adjustment.
NOTE: The hex nut on the clutch link just above the spring on the clutch linkage is NOT an adjustment. This nut should be tightened just enough to hold the spring snug and prevent the spring from rattling when traction clutch is released.

DRIVE DISC ADJUSTMENT
The only adjustment for the drive disc is made by adjusting the length of the traction clutch rod. With the clutch handle in the full upright position and the clutch bracket down against the stop, tighten the allen screw in the rod adapter. To check the adjustment, push the Sno-Thro with the clutch handle up; it should roll freely. While pushing the Sno-Thro, slowly lower the clutch handle. The wheels should start to drag with the clutch handle approximately halfway down to the handlebar grip when properly set. If necessary, adjust the clutch rod in the rod adapter to secure this adjustment.
NOTE: The hex nut on the clutch link just above the spring on the clutch linkage is NOT an adjustment. This nut should be tightened just enough to hold the spring snug and prevent the spring from rattling when traction clutch is released.

BELT REPLACEMENT

CAUTION:
SINCE REPLACING THE BELTS WILL INVOLVE TURNING THE ENGINE OVER WITH THE STARTER, THE SPARK PLUG WIRE MUST BE DISCONNECTED DURING THIS PROCEDURE.
The drive belt and the attachment drive belt are both accessible by tipping apart the blower housing and tractor as follows:

1. Remove the nut and-washer holding the worm clevis on the bracket. Remove the chute crank by sliding it back in the bracket and out of the way.
2. Remove the two flanged whizlock screws securing the belt guard to the tractor. Remove the belt guard.
3. Remove the top cap screws and loosen the lower cap screws on each side that secures the blower housing to the frame. As the blower housing and tractor are tipped apart, roll the belt off the engine sheave between the sheave and belt finger. This can be easily done by pulling the recoil starter rope to rotate the engine sheave. With the belt disconnected, the blower housing may then be tipped from the frame,

REPLACEMENT OF THE BLOWER DRIVE BELT
The blower drive belt remains on the sheave on the blower housing. Place the new belt on the sheave. Hold it in position on the sheave as the blower is tipped into position on the tractor. Be sure the brake shoe seats on the beit as the units are tipped together. Once assembled, roll the blower belt on to the engine sheave and position the idler on the outside of the belt.
REPLACEMENT OF TRACTION DRIVE BELT
With the blower and tractor tipped apart, spring the idler from the drive belt and remove from around the lower sheave and engine sheave. Install the new belt on the engine sheave and lower sheave. Then spring the idle back into position on the outside of the drive belt.
With the belts in position and the idler in place, check the belt alignment. The engine sheave and the tractor sheave must align with one another. If the sheaves are not properly aligned, loosen the setscrews on the engine sheave and align the sheaves. Retighten the setscrews.
REPLACEMENT OF BLOWER HOUSING

1. Tip the blower and tractor together. Hold the blower drive belt up as the units are tipped together. Be sure the blower brake shoe seats on the blower sheave. Secure with the two cap screws into the frame. As the cap screws are tightened hold up on the handlebars to be sure the two units are secured tightly together.
2. Roll the blower belt on to the engine sheave. Pull the ,-\recoll starter rope to turn the engine sheave and roll the belt into place under the belt finger.
3. Check the belt finger spacing. There should be 1/8 inch clearance all around the belt finger and belt with the blower clutch engaged. Readjust the belt finger if required.
4. Check the sheave alignment with the blower belt in place and clutch engaged. Readjust the position of the blower sheave as required to align the sheaves. It may be necessary to tip the blower housing away from the tractor to gain access to the blower sheave.
5. Replace the belt guard and chute crank assemblies. Readjust the chute crank as described in the paragraph above. Replace the spark plug wire.

REPLACEMENT OF FRICTION WHEEL

1. Tip the machine up on the blower housing and brace securely. Remove two cap screws at back of frame securing the bottom cover and loosen two cap screws at front  frame sides and remove the cover.
2. Remove the four whizlock nuts holding the bearing flange on the right hand side of the frame. Remove the bearing flange and carriage bolts.
3. Remove the hairpin cotter from the traction clutch rod. Pull this rod from the clutch fork arm and tip it up and out  of the way.
4. Slide the friction wheel assembly and hex shaft to the right ™ until the left end of the hex shaft comes free of the left bearing. Then slip the whole assembly back to the right and pull it forward out of the frame.
5. With the friction wheel assembly out of the frame, the three cap screws holding the friction wheel to the hub may be removed and the friction wheel removed.
6. Position a new friction wheel on the hub and secure with the three cap screws. Tighten securely.
7. Slip the right end of the complete friction wheel assembly and hex shaft into the hole in the right side of the frame. Position the friction wheel hub in the forks. Slide the hex shaft to the left and into the left bearing being sure flat washer is in position. See that the pinion gear meshes with the large gear.
