Graco GH130 relies on a precision V-profile fan belt (item 44) to spin its high-flow cooling fan and hydraulic pump drive. Graco’s OEM belt is molded from heat-stable EPDM, embedded with aramid tension cords, and sized to maintain factory-set tension no glazing, no stretch, no mystery cross-numbers. Independent life-cycle tests in Graco’s service bulletin show up to 2× longer service life versus aftermarket belts under 2,000-psi continuous duty
Compatible Graco Hydraulic Sprayers
The same belt drives every sprayer in Graco’s small-frame gas-hydraulic line:
- GH130 Convertible Standard & Electric-Ready (P/N 24W923, 24W924)
- GH200, GH230, GH300 Standard Series shared pulley stack in the 311797 parts manual
- Older EH200/HD1200 rigs that reuse the same 96-tooth fan pulley
Running a mixed fleet? The belt service interval aligns with pump packings on Ultra Max II 1095/1595 and Magnum Pro X7 electrics. Stock one truck bin for belts, one for magnum pro x7 parts.
Key Specs at a Glance
- Profile: 5-rib EPDM V-belt with aramid tensile member
- Effective Length: 33.9 in (861 mm) – holds Honda GX-series engines in the sweet spot for fan CFM
- Temperature Range: -40 °F to +230 °F
- Change Interval: 500–750 engine hours (aligns with V-Max Blue packing swap)
How to Swap the Belt in Under Five Minutes
- Relieve system pressure and lock the gun trigger.
- Loosen the belt-guard knob 55 and swing the guard up.
- Lift the Honda engine to relax tension, then walk the belt off the fan (pulley 96) and drive pulley 43.
- Thread the new belt, lower the engine to set factory tension, drop the guard, and tighten 55.
Total downtime: about the time it takes to wipe tips with Pump Armor. Keep a spare in the toolbox next to your graco pump replacement parts kit and your crew is back at 3,300 psi before the paint skin sets.

Shop-Floor Tips for Belt & Pump Longevity
Log hours, not weeks: change belts and V-Max packings every 750 hours then reset the counter in your maintenance app.
Store belts flat, not hung: bending a V-belt around a hook creates memory that shortens life.
Pair new belts with fresh hydraulic oil: a cooler system means less swell in your leather/UHMWPE packings.
Color-code storage bins: yellow for belts, red for graco pump replacement parts, blue for graco airless parts night shift pulls the right box every time.
