How do you measure a snowmobile deflection belt?
And the proper adjustment for this belt is an inch and a quarter of space between your straightedge. And your belt.
How do you adjust the belt deflection on a Polaris snowmobile?
Pull the panel out and lift up to remove. Next place a straightedge on the belt. Then apply downward pressure between the clutches to measure the deflection.
What is proper belt deflection?
Put a straight edge between the clutches and pull down on the center of the belt. The proper adjustment for the snowmobile shown in the video is 1 1/4″ of space between the straight edge and belt. The belt deflection on the belt, however, is about 1 1/2″, meaning it’s too loose and requires adjustment.
How do you check snowmobile clutch alignment?
You can use see a pry bar that isn’t bent or any kind of straight edge I’m just for illustrations I’m gonna use my clutch alignment tool but as a straightedge.

How do I know if my snowmobile belt is worn out?
Your snowmobile belt is made out of rubber, and rubber tends to show wear easily. Tears, missing cogs, cracks, cordage sticking out of the sides of the belt and looseness are all common signs that your snowmobile belt has been worn out and should be replaced.

How much deflection should a belt have?
At center of the span length apply a force F (using a belt tension gauge) perpendicular to the belt span, large enough to deflect the belt 1/64” for each 1“ of belt span, q. So, for a 32” span, the deflection amount would be 32/64” or 1/2”.
What is the correct amount of deflection mm for the belt?
Force/Deflection: Belt span tension can be measured by deflecting a belt span 1/64″ per inch (0.4 mm per 25 mm) of span length at midspan, with a known force (see Figure 20).
Do I need a clutch alignment tool?
Installing a clutch with a clutch alignment tool is definitely preferred, and in some cases may be required. But for many installs, a little ingenuity is all you need to install your clutch without relying on tools you don’t need.
Can you start a snowmobile without a clutch?
You could start the engine with the primary clutch on to get the engine warm and then remove the primary if you have to do any engine running w/o it on. There will be absolutely no damage to anything on the engine if you run without the primary clutch.
How much slack should a serpentine belt have?
The belt should have about a half an inch of play when at the appropriate tightness. If there is less than a half an inch, the belt will need to be loosened, if there is more, it will need to be tightened.
What happens if snowmobile belt is too loose?
If your deflection is too loose, it takes more throttle until the clutch grabs the belt, making the engagement of your drive ‘harsh’. It will grab really suddenly and this puts a big strain on the fibers in your belt.
How long should a belt last on a snowmobile?
As a general rule, snowmobile belts last around 1,000-3,000 miles. On sleds that regularly run off-trail, the belt will typically last only 1,000-1,500 miles. But on trail sleds, you can normally get 2,000-3,000 miles out of the belt, or even more!
How do I check my belt deflection?
Check existing belt deflection
Place a straight edge between the clutches and pull down on the center of the belt. Midway between the clutches, use a tape measure or ruler to measure the distance between the belt and the straight edge. This is the belt deflection.
How is V belt deflection calculated?
Calculate the deflection distance by: t/64 = deflection. Note from Figure 26 that the deflection distance is always 1/64″ per inch of span length (for example, a 32″ span length would require a deflection of 32/64 or 1/2 inch).

How do I make sure my clutch is aligned?
First, insert the tool into the clutch disc. Make sure the clutch is facing the correct direction. The tool should stick all the way through the spines on the disc. Then place the clutch on the flywheel, and engage the alignment tool into the pilot bushing or bearing in the center of the crankshaft.
What to use if you dont have a clutch alignment tool?
Instead of freaking out, grab a socket or tube of some sort which is a bit smaller size than the flywheel snout, and wrap some tape around it to fit into the flywheel and disc size. You might even have a different toll from a past job that is smaller and can be used.
Can you run a snowmobile engine without a belt?
You can start a snowmobile without a belt, but you must do it with extreme caution. Running, though, will be impossible. And running the engine above idle, especially without a belt, is dangerous because you risk damaging the sheaves or activating the clutch, which might cause the engine to blast off.
How do you make a snowmobile pull start easier?
If you feel it’s hard to pull-start your sled, here are some tips to make it easier:
- Make sure that the starter works properly, and the pulley is aligned perfectly.
- Check the tension of the belt, if it’s too tight can also cause a difficult pull.
- Consider a larger starter pulley.
