How to re-seat or replace the auger belt on a John Deere 1330SE Snow Blower.


This solution should apply to John Deere 1330se, Simplicity L1730e, Murray 1330se and other similarly equipped models.

As you may have read in my previous post, my snow blower had a “date” with a large rock and lost. In addition to bending one of my “fin tabs” on the impeller, the accident also forced my auger belt to jump off the pulley, getting mangled during the process.

I thought I licked the problem when I repaired my impeller and wrestled the old belt back on to the auger pulley, but the belt kept jumping off the track. I visually inspected the belt with the auger running and noticed a significant slack, forcing the belt into a whipping motion.

Since I wasn’t sure exactly what was causing this problem, I decided to replace my belts first, then triage the problem.

Please note that I originally planned on replacing both the engine and auger pulley belts. I ended up replacing the auger pulley belt alone because the other belt was in excellent condition.4

The process of replacing the belt seem daunting at first, but it really wasn’t that hard with the snow blower basically splitting in half after removing few screws (one side of this split is shown inside the dashed line).


  • V-belt, 4L, 38.35, impeller pulley (Part No. 1736421YP)
  • V-belt, 3L, 33.13, engine pulley (Part No. 1733324SM)
  • Large, adjustable Velcro straps (to hold down the auger control lever/handle – 24 x 2 Inch Cinch Straps – 5 Pack
  • Ordinary rubber bands (2 or 3) or black electrical tape (to hold the belt in place during replacement)
  • You can check out this one at Amazon (Medline Sensicare 200 Non-Sterile Powder-Free Latex-Free Nitrile Exam Gloves, Large, 200 Count) or if you belong to BJs, they have a similar item for around $30.


  • Mini and large ratchets and socket extenders
  • 10 mm / 1/2 inch sockets
  • 9/16″ and 1/2″ wrench
  • Scrap blocks of wood (to support the auger hood assembly)
  • Box container, chair, or short ladder (to support the engine assembly)


There are two ways to remove the auger pulley belt: 1) via the traction control cover panel (accessible only from the bottom of the machine) or detaching the engine side from the auger hood assembly. I chose the latter method because:

  • It was much easier to remove the belt;
  • I didn’t have to empty the gas tank (in order to access the traction control cover panel, I have to tip the machine 90 degrees)

STEP 1 – Remove the spark plug wire;
STEP 2 – Remove two screws (one from each side) using a 10 mm socket to remove the belt cover. If you hear a rattling noise while removing the cover, you may have some extra shear/cotter pins stored inside the cover! Just pop off the top lid to access them (fig. 1);
STEP 3 – Disconnected two wires that control the chute movement (fig. 2);
STEP 4 – At this point, we are ready to separate the auger hood assembly from the engine side. To control the separation rate (each side will tip away rather quickly if not supported), I positioned some scrap wood blocks underneath the augers and a container box under the handles on the engine side;
STEP 5 – Each side has 3 hex screws (Fig 3a and 3b) that are holding the auger assembly to the engine assembly. Please note that unlike 2 top screws marked “A”, the bottom screw “B” is seated on an open slot;
STEP 6 – Remove top 2 “A” screws (Fig. 3a & 3b) from each side. Then carefully loosen 2 bottom “B” screws, making sure NOT to remove them all the way. Once the bottom screws are loosened, each side will tip away from each other until hitting the support we placed in Step 4;

STEP 7 – Fig. 4 shows the end result from removing the top 2 screws from each side. I carefully lifted the handles by about 2 inches to “unhinge” the two bottom screws from the open slot brackets, allowing me a clear path to remove the mangled auger driving belt;
STEP 8 – Examine the new replacement belt carefully and made sure the narrow end (usually a grooved side) was installed face down (this side made contact with the pulley) (Fig. 5);
STEP 9 – Used a rubber band to tie the belt so that it would stay in its place and not get in the way when I re-assembled my snow blower;
STEP 10 – At this point, I started to re-assemble the snow thrower by “re-hinging” the bottom screws and tightened them (not the all the way). I then lined up the remaining screw holes for screw installation. Make sure to never force the screws back in! When that happens, the holes need to be re-aligned;

STEP 11 – Removed the rubber band then routed the auger driving belt around the idler pulley, then around the engine pulley. Idler pulley assembly (consisting of pulley and metal bracket) is attached to a spring so it can easily be pressed down to create some space to route the cable. The pulley itself sits on a flat metal bracket that can slide 4 inches or so horizontally (fig 10).
STEP 12 – To adjust the belt tension, I simply have to loosen the bolt on the pulley (I used a Craftsman 9/16″ wrench – fig 11) to allow it to slide on the metal bracket. Two things of importance:

  1. The belt SHOULD NOT be spinning when the Auger lever is NOT ENGAGED.
  2. The auger SHOULD STOP TURNING within 5 seconds of letting go of the auger lever

If these conditions do not happen, it means the belt tension IS TOO TIGHT. See fig. 9 for detailed spacing requirement.
STEP 13 – I also noticed the belt guide, which prevents the belt from jumping off the pulley, had moved quite a bit, probably from the last damage. To adjust the spacing, I used a Craftsman 1/2″ wrench to loosen its bolt and slid the guide closer to the belt, using the spacing requirements stated in the JD operations manual (fig. 9).

STEP 13 – With the cover off, I re-attached the spark plug wire, started the snow thrower then held down the auger lever with a Velcro so that I can visually confirm that everything was working correctly (Keep your hands away from any moving mechanisms!!)
STEP 14 – Satisfied with the result, I turned off the engine, reinstalled the cover and had a nice cold beer.


Rather than spending over $300 to do get this repair done by someone else (one dealer’s quote), I saved a ton of money by doing it myself with a little bit of elbow grease and $25 in parts.

Hopefully I was able break the information down logically to show you that it really was not that complicated.

When should I replace my snowblower auger belt? ›

Snowblower belts start to wear out after 5 to 7 years, and should be replaced. You can save money by doing the job yourself.

Why is my snowblower auger shaft not turning? ›

If the auger doesn't turn even though the main shaft is being powered and the shear bolts or pins are intact, then it's likely the gears inside the gearbox have stripped and the gearbox assembly will need to be replaced.

How do I know my auger belt size? ›

The other means of identification is take a measuring tape, and run it over the pulleys for the belt, the outside dimension of the pulleys will be size of belt required. Have pulleys at there lowest point, so the belt will have enough adjustment to tighten.

How tight should a snowblower auger belt be? ›

When It's engaged, it should be fairly tight. It may or may not have an adjustment to tighten the belt when needed. One thing to look at is if your belt is old, it may have worn the sides of it enough to actually drop the belt farther into the pulley which could cause slipping under snow loads.

Why is my snowblower auger not stopping? ›

If the auger will not stop turning when the engine is left to idle, there may be an issue with your clutch sticking. The clutch is calibrated to engage the driveshaft and start powering the auger when the drive shaft reaches a certain rotational speed, and to disengage when the rotation falls below that speed.

How many belts are on a snow blower? ›

As a part of snow blower maintenance, remove the belt cover and inspect the belts, idlers, and pulleys. For most two stage snow blowers, there are 2 or 3 belts under the cover. One belt will drive the auger, and the other will drive the wheels.

Why does my snowblower belt keep breaking? ›

Usually when a belt gets messed up like this, it is either because the belt is of the wrong size or if an original equipment belt was not used. Assuming you are using excellent quality belts, then the problem is almost always pulley or alignment related. You snow throwers design uses a "unique" split pulley system.

Why is my snowblower auger not turning under load? ›

A broken shear pin is the most common reason the snowblower auger won't turn properly so replace any broken shear pins. Worn or loose belts also prevent the snowblower auger from spinning. Check and adjust the belts and replace any broken or worn belts when you see the snowblower auger not turning.

Why is the auger on my snowblower turning slow? ›

It could be because the auger drive idler isn't applying enough tension to the auger drive belt (inside the machine) for the belt to grip the auger pulley and make the pulley turn fast enough. The other reason could be that the auger drive belt is worn, which can lead to the same result.

Why is only half of my snowblower spinning? ›

If only one of the two augers on your snow blower will turn, it is likely that the shear pin that connects to the driveshaft has broken. Both augers, as well as the impeller, are all connected to the drive shafts by shear pins that are designed to snap if they are met with a certain amount of force.

How do you fix a stuck auger? ›

Try Dampening the Soil

Sometimes, when you're drilling through a harder surface or drier ground, your auger can get stuck. Pouring some water around the hole will allow the soil to loosen around the tool, giving you more wiggle room to slide it out.

Why is my snowblower auger working but not throwing snow? ›

A stretched or damaged auger drive belt won't spin the auger fast enough to throw snow off the pavement and out through the chute. Examine the auger drive belt. If the belt is okay but the cable isn't keeping the belt snug on the pulleys, adjust the auger drive cable.
