What do the numbers mean on a primary clutch spring?
So if we take a given spring as an example (160/260), we know that the first # (160) is what controls the engagement speed (or rpm that the clutch engages), higher numbers = higher engagement, lower numbers = lower engagement. The second number (260) is what balances the push of the arms.
What does a heavier clutch spring do?
heavy springs raise rpms, light springs lower rpms. if you have too much spring you can reduce the spring rate, and or add weight the primary arms to reach the desired rpm range. if the if you have too weak of a spring, you can up the spring force, and or lighten the primary arms to reach the desired rpm range.
What does heavier clutch weights do?
Weights also affect how fast the clutch can shift. Using heavier weights will make the clutch try to shift open faster. This is good because the faster the clutches shift open, the faster the RZR will accelerate.
How long do Snowmobile clutch springs last?
With proper maintenance, a snowmobile clutch will typically last between 5,000-10,000 miles before it needs repairs or replacement. If you don’t perform regular maintenance to your snowmobiles primary or secondary clutch, you can expect them to last between 3,000-5,000 miles before you run into issues.
What does secondary clutch spring do?
From the secondary clutch looking at the primary clutch; More secondary spring force resists the push of the primary clutch lever and allows for more rpms. The spring force affects rpms, not top end mph.
What do lighter clutch weights do?
Yes, the motor is making more power at lower elevation (3000ft v 9000ft). With the lighter clutch weights you will quickly over rev and trip the computer to Big Brother protection mode and cause it to fault. You would also be way over the target RPM range and loose power drastically.
What does changing secondary clutch spring do?
More spring force “increases the upshift point” and allows the engine to build more horsepower before the clutch starts to upshift. From the secondary clutch looking at the primary clutch; More secondary spring force resists the push of the primary clutch lever and allows for more rpms.
Do clutch springs wear out?
As the clutch springs heat up and cool down over the course of a ride day, the materials begin to degrade. OEM springs are built specifically for each model and usually work well, but over time they will wear out and soften.
What is primary and secondary clutch?
The secondary clutch is a much larger diameter than the primary clutch and the belt wraps around the outside of the two sheaves, again one being fixed and one being movable. When the primary clutch begins to shift it forces the belt higher in the primary clutch.
