Downtime on a GH230 can cost thousands per hour. Whether you’re blasting intumescent coating onto structural steel or spraying two-part polyurea on a water tank, you can’t afford a blown recoil spring or a clogged fuel filter. Graco® GH230 relies on a Honda® GX270 9 HP engine coupled to a high-efficiency hydraulic pump that drives an Endurance™ MAXLIFE fluid section. When any piece of that powertrain falters, production stops. That’s why pros look to SprayersAndParts.com for factory-serialized graco paint sprayers parts that bolt in, prime up and put money back on the clock. From spark plugs to hydraulic pump couplings, we stock every OEM component that keeps the GH230 roaring.

A smart inventory strategy covers multiple rigs with one bin of spares. GH230 engine components fit or share key cross-parts with:
1 • Oil every 100 hrs. 10W-30 API SJ; torque drain bolt 30 N·m.
2 • Clean foam pre-filter daily. Hot water + dish soap stops dust scoring the bore.
3 • Log fuel hours. Replace fuel filter every 250 hrs—gum kills carbs.
4 • Check governor spring tension weekly. 5 mm deflection keeps 3 300 psi rock-steady.
5 • Inspect coupling at every oil change. Replace spider if elastomer cracks—$18 part saves a $600 crankshaft.
