50mm water pump pulley

€8.90

Tax included

This pulley is designed to be mounted directly on the shaft (axle) of karting. It serves as a starting point for the belt that causes the water pump, ensuring continuous circulation of the coolant proportional to the speed of rotation of the axle.

Sustainable material: Its high-density plastic manufacture offers excellent resistance to gum splash and temperature variations while lightweight.
Standard dimension: With a diameter of 50 mmIt offers a conventional transmission report for most competition water pumps.
Simplified installation: Designed to adapt to standard karting axes, it usually attaches to a robust clamping system to prevent slippage.

- Installation and maintenance

Positioning: Align perfectly the pulley of the rear axle with the pulley of the water pump to prevent the belt from jumping or does not wear out prematurely.
Tightening: Make sure the mounting screws are tightened evenly. A slight net brake point can be used to counter the vibration of the shaft.
Verification of the belt: Use O-rings or notched belts adapted to the profile of the pulley. The tension must be firm but must not brush the rotation of the pump.

? Michel's trick

"In karting, the water pump pulley undergoes all the vibrations of the rear axis. The trick: Check regularly that no gum debris (pick-up) was lodged in the groove of the pulley. My Pro Council: Always plan an alternative pulley in your toolbox. Even if the plastic is solid, a shock with another kart can sometimes split, and without cooling, your engine will not make two more turns! "

❓ FAQ SEO (Frequently Asked Questions)

Q: Is this pulley compatible with all axis diameters?

A: The plastic pulleys are often specific to a axle diameter (30mm, 40mm or 50mm). Check that the inner diameter is your back tree before purchase.

Q: Why choose plastic rather than aluminum?

A: The plastic is lighter and offers some flexibility that can absorb micro-vibrations, thus protecting a little better the bearings of your water pump.

Q: How many belts should we install?

A: Most drivers install two straps per security. If a breakage, the second ensures the continuity of cooling to finish the handle.
