Snowblower: Won't self propel
Inspect the drive control cable and adjust if necessary. Check the drive belt for excessive wear and replace it if necessary. Replace the friction disc if necessary.
These repairs may help solve your Snowblower problem:
Adjust or replace the snowblower skid shoes
The skid shoes control the height of the auger housing. They wear down over time. Adjust the skid shoes as needed to maintain the proper height of the auger housing. Skid shoes are reversible; turn them over if one side is worn out. Replace them when both sides are worn out.
Adjust or replace the snowblower belts
A worn or loose belt can slip or squeal when the snowblower is in use. Physically examine the belt and pulleys. If the belt is worn, replace it. If the belt is sound, adjust the pulleys to tighten the belt.
Replace the snowblower friction disc
The friction disc is attached to the axle that drives the tires to move the snowblower. Examine the friction wheel
Do a snowblower tune-up
A tune-up restores the snowblower to its peak operating condition. A tune-up includes changing the oil, cleaning the engine, replacing the air filter, checking the ignition system, inspecting the carburetor, testing the battery, adjusting the throttle and choke controls, and adjusting and lubricating all moving parts.
Repair or replace the snowblower tire or wheel rim
Inspect the tires should be inspected before each use. If a tire is flat, repair or replace it. If the wheel rim is damaged, replace it.
Adjust the snowblower drive clutch cable
The drive clutch cable moves the drive wheel into contact with the friction disc, which rotates the axle so the snowblower moves. If the cable isn't moving the drive wheel into contacts the friction wheel, adjust the cable.
Replace the snowblower gearcase assembly
The auger drive system uses a gearcase to rotate the auger shaft so that the augers can move snow. Replace the gearcase if the auger won't spin properly or at all.
Replace or adjust the snowblower scraper blade
The scraper blade at the bottom of the auger housing is subject to wear. Inspect it periodically and adjusted as necessary. Replaced it when it wears out.
