Why is this category essential?

Safety and protection: The belt guard covers moving parts like the belt and pulleys, reducing risk of injury and preventing debris ingress — as described in the manual for the PowrTwin 4900.

Proper belt alignment & tension: A correct belt guard assembly helps maintain belt positioning during operation and when converting power sources (e.g., gas to electric) on the PowrTwin 4900

Maintenance made easier: By replacing worn guard components such as mounting brackets or screws, you can avoid belt slippage, misalignment, and extend the working life of your sprayer.

Key parts you’ll find

0290628A Belt Guard Weldment – main guard unit (weldment) for the PowrTwin 4900 belt guard assembly.
0290627A Front Belt Guard (Red) – front cover panel designed for PowrTwin 4900 / PowrTwin Plus belt guard assemblies.
0290626A Mounting Bracket Weldment PK – bracket kit used to mount the belt guard assembly on the frame.

Hardware such as screws (e.g., 9805415 BHCS 10-32×0.50 T-25) and other fasteners used in belt guard assembly.

Maintenance & usage tips

When replacing the belt guard or performing belt changes, loosen the front guard bolt and lift the front end of the guard to access the belt/pulley area.
Ensure belt tension is correct: The belt guard assembly should accommodate proper alignment of belt and pulleys without interference.
Inspect mounting brackets, weldments and braces for cracks, wear or deformation — damaged guard components can lead to belt mis-tracking or failure.
Make sure all fasteners (screws, bolts) are tightened per spec to ensure the guard remains secure during high-duty operation.
Use correct OEM-matched parts (e.g., 0290628A, 0290627A) to ensure fit-and-function; retrofit/aftermarket guards might not offer same level of protection or alignment.
