DHS Equipment supplies this part direct, so you can be confident you are ordering the correct component for your Multiquip masonry saw. Verify your model code against the fitment list above before ordering to confirm compatibility.
Key Features
- Genuine OEM Drive Accuracy — Manufactured to original pulley diameter and bore specifications, maintaining correct belt-drive ratio and blade speed across supported saw models.
- Direct Bolt-On Installation — Engineered to match the original mounting interface on the engine and jackshaft, so the pulley seats and secures exactly as the factory unit did.
- Broad Masonry Pro Saw Compatibility — Confirmed fitment across MP25E1, MP25E3, MP275E3, MP2H, MP2050E1, MP2050E3, MP2090HP, MP1H, MP115E, MP120E, and MP1455HP models.
- Consistent Power Transfer — A correctly sized and balanced pulley keeps belt tension and drive engagement stable, protecting both the engine and blade arbor from unnecessary load fluctuation.
- Blade Speed Safety — An out-of-spec or worn pulley can alter blade RPM beyond the rated range; replacing with a genuine OEM pulley keeps surface speed within the design envelope for the installed blade.
The engine jackshaft pulley is the drive interface between the saw's engine output shaft and the jackshaft assembly, transmitting rotational power via belt to ultimately spin the cutting blade. Its diameter and groove profile directly determine belt tension and blade RPM — if the pulley is worn, cracked, or incorrectly sized, belt slip, vibration, and inconsistent blade speed follow. Replacing a damaged or worn pulley with a genuine Multiquip 28322-003 restores the intended power transfer path and helps the saw cut cleanly and consistently through masonry materials.
