Part of the John Deere Repair Manuals.
A friction disc drive that slips under load is the nastiest job on these machines, and this John Deere service and troubleshooting manual (OEM #381048) works through it in 180 pages covering six snow thrower models: 726E, 827E, 1028E, 1330SE, 1332PE, and 1338PE. Electrical schematics trace the ignition module and stator circuits across all six, plus the chute rotation motor circuit on the 1028E, 1330SE, 1332PE, and 1338PE, with component locations so a dead headlight or a no-spark condition stops being a mystery. All six run Briggs & Stratton engines (Snow Series on the 726E through 1028E, Professional Series on the 1330SE through 1338PE); engine troubleshooting runs from systems check through carburetion, compression, and crankshaft repair, while the power train chapter handles drive belt tension, axle replacement, and the speed selector fork. Torque the friction disc capscrews to 6-10 lb-ft on reassembly. Bookmarks put the section you came for two clicks away, and the text layer turns up any spec by keyword.

John Deere 726E, 827E, 1028E, 1330SE, 1332PE, 1338PE Common Problems This Manual Covers
Traction drive will not move machine, or unit creeps and will not stop when lever released
Inspect the friction disc rubber for wear, glazing, or oil contamination and replace it if the surface is hard or cracked. Measure the drive spring length; it should be 3 in. to 3-3/8 in. (76 mm to 85 mm), shown on page 124. Check the control linkage for binding through the Power Train procedures starting on page 109.
Manual Section: Power Train p. 124Traction drive belt squeals and slips climbing the driveway, wheels stop pulling under load
Inspect the traction drive belt for glazing and oil; replace it if shiny or cracked. Set the belt stop 1/16 in.-1/8 in. (1.6-3 mm) from the engaged belt per the specs on page 110, then torque the idler traction drive bolt to 10-15 lb-ft. (13.5-20.3 Nm), or 10-14 lb-ft. (13.5-19 Nm) on the 827E. Confirm the idler pulley spins free without wobble.
Manual Section: Power Train p. 110Engine will not start or surges badly after summer storage, smells like stale fuel
Drain the stale fuel and refill with fresh gasoline per the fuel guidelines on page 25. Remove the carburetor bowl and clean the main jet. Pull the spark plug, check for fouling, and gap it to 0.030 in. (0.76 mm); torque it to 180 lb-in. (20 Nm) on reinstall. Work the no-start chart starting on page 38 if it still refuses to fire.
Manual Section: Engine Troubleshooting and Repair p. 38Frequently Asked Questions
What is the torque specification for the auger case capscrew on a John Deere 1330SE snow thrower?
The torque specification for the auger case capscrew, which secures the auger housing, is 6-8 lb-ft (8.13-10.9 Nm). p. 147
What are the replacement specs for the auger drive belt on a John Deere 726E, 827E, 1028E, 1330SE, 1332PE, 1338PE?
The auger drive belt deflection should be 1/2 inch (12.5 mm) when checked with moderate thumb pressure. If the belt requires adjustment, loosen the nut on the idler pulley and move the pulley toward the belt. p. 160
How do you fix John Deere 1028E auger drive belt slips or pops off under load, impeller stops throwing snow?
Check auger drive belt deflection and adjust to 1/2 in. (12.5 mm) using the procedure on page 160. Inspect the belt for glazing, cracks, and missing cogs; replace it if worn. Set belt guide clearance to .03-.06 in. (.76-1.5 mm), then torque the belt guide capscrew to 10-14 lb-ft. (13.5-19 Nm) per the specs on page 147. p. 160
How do you fix auger spins but throws snow only a few feet, chute clogs constantly in wet snow?
Check both auger shear pins first with the engine off; a sheared pin lets the auger freewheel while the shaft spins. Clear packed ice from the impeller and inspect the blades for wear, following the auger system procedures starting on page 145. Verify the auger drive pulley set screw is torqued to 20 lb-ft. (28 Nm). p. 145
