Adjusting the shift cable for smooth drive performance
Before fine-tuning other drive components, start by checking and adjusting the shift cable. Proper tension ensures the transmission engages each speed correctly and helps the snowblower move consistently in both forward and reverse.
Park the snow thrower on a level surface with the engine shut off.
Place the shift lever in the fastest forward speed position.
Loosen the hex nut on the shift cable index bracket.
Pivot the bracket downward to remove slack in the shift cable. If you’re not able to remove slack from the cable by moving the bracket downward, disconnect the shift cable from the index bracket and reconnect it in a lower hole so that you can remove slack from the shift cable.
While holding the shift cable tight, tighten the hex nut.
Test the snowblower drive performance and continue to adjust the cable until the snowblower drives properly at all selected speeds.
Complete snowblower maintenance to keep everything running smoothly
Once the shift cable is adjusted, it’s a good time to take care of other key maintenance tasks. Many of these checks work well together because they involve opening the same covers, accessing the same components, or tilting the snowblower for better reach. Doing them in one session helps prevent mid-season breakdowns.
Check the auger belt and ground drive belt for wear
Remove the belt cover and inspect both belts for cracks, glazing or stretched areas. Replace the belts if they’re worn or damaged.
Your owner’s manual will show the correct routing for your model.
Tune up the snowblower engine
A seasonal snowblower tune-up keeps the engine running strong in cold weather. Use this checklist:
Lubricate the auger shaft and housing
To keep the auger turning freely, lubricate the auger shaft and bearings. Remove the shear pins, spray the shaft with SNOW-JET silicone lubricant, and reinstall the pins.
Finish by coating the auger housing and chute to reduce snow buildup and improve throwing distance.
Grease the axle and check tire air pressure
Tilt the snowblower forward (with an empty fuel tank), remove each wheel, and apply multi-purpose automotive grease to the axle.
Check tire pressure with a gauge and adjust to the PSI listed on the sidewall.
Adjust the skid shoes if needed
Make sure the skid shoes sit flat and provide enough clearance for the shave plate. If they’re uneven or worn down, adjust the skid shoes.
Flip or replace them if the shave plate is starting to scrape.
