Improve T4 2020 Drivetrain Smoothness with a 20T Bearing Pulley

The XRAY 305578 Fixed Pulley supports the T4 2020 layshaft with a bearing-mounted 20T unit to promote even power transfer. Fitted bearings help reduce friction and keep the drivetrain running true.

Key Advantages

  • Precision Engineering: Tooth form and dimensions are produced to ensure reliable engagement with the layshaft.
  • Solid Build: Composite shims are provided to maintain consistent alignment under load.
  • Exact Fit: Manufactured for XRAY T4 2020 chassis codes 300026 and 300027 to ensure proper fitment.

Assembly Notes

When assembling the XRAY 305578 pulley, make sure bearings are pressed in squarely and that the pulley runs without wobble on the layshaft. Regular inspections of the teeth, shims and bearings will help sustain performance.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Is this a direct replacement for original parts?

Yes, it is made to match T4 2020 specifications and should replace the original pulley on compatible chassis numbers without modification.

Should I change shims when fitting?

Start with the supplied shims then adjust if you notice lateral movement or binding. Small shim changes can correct backlash and side play effectively.

What signs indicate the pulley needs replacing?

Signs include noisy or rough bearing rotation, visible tooth wear, or increased drivetrain play. Replace worn components to avoid further damage.
