MTD E740F manual Servicing Your Snow Thrower, Engine, Augers, Belt Removal And Replacement

Page 15

Gear Case

The gear case is lubricated with grease at the factory and does not require checking. If disassembled for any reason, lubricate with 2 ounces of Shell Alvania grease EPR00, part number 737-0168. Before reassembling, remove old sealant and apply new sealant.

IMPORTANT:Do not overfill the gear case. Damage to

the seals could result. Be sure the vent plug is free of grease in order to relieve pressure.

Engine

Refer to the separate engine manual packed with your unit for all engine lubrication instructions.

SECTION 8: SERVICING YOUR SNOW THROWER

WARNING: Before servicing, repairing, or inspecting, disengage all clutch levers and stop engine. Wait until all moving parts have come to a complete stop. Disconnect spark plug wire and ground it against the engine to prevent unintended starting.

Engine

Refer to the separate engine manual packed with your unit for all engine maintenance procedures.

Augers

The augers are secured to the spiral shaft with two shear bolts and hex lock nuts. If you hit a hard foreign object or ice jam, the snow thrower is designed so that the bolts may shear.

Refer to Figure 18.

If the augers will not turn, check to see if the bolts have sheared. Replacement shear bolts and hex lock nuts have been provided with the snow thrower. When replacing bolts, spray an oil lubricant into shaft before inserting new bolts.

Belt Removal And Replacement

Auger Belts

Remove the plastic belt cover by removing the two self-tapping screws. See Figure 19.

Drain the gasoline from the snow thrower.

Tip the snow thrower up and forward so that it rests on its auger housing.

IMPORTANT: NEVER replace the auger shear bolts with standard hex bolts. Any damage to the auger gearbox or other components as a result of doing so will NOT be covered by your snow thrower’s warranty.

Shave Plate and Skid Shoes

The shave plate and skid shoes on the bottom of the snow thrower are subject to wear. They should be checked periodically and replaced when necessary. To remove the skid shoes, proceed as follows:

Remove the six carriage bolts, bell washers, and hex nuts which attach them to the snow thrower.

Reassemble new skid shoes with the six carriage bolts, bell washers (cupped side goes against skid

shoes) and hex nuts. Make certain the skid shoes are adjusted to be level.

To remove shave plate, remove the carriage bolts, bell washers, and hex nuts which attach it to the snow thrower housing. Reassemble new shave plate, making sure heads of the carriage bolts are to the inside of the housing. Tighten securely.

Remove the six self-tapping screws from the frame cover underneath the snow thrower.

Roll the front and rear auger belts off the engine pulley. See Figure 20.
