What Is PA-CH730-0019?
PA-CH730-0019 is the manufacturer part number for the CH730-0019 Command PRO engine configuration produced for Vermeer replacement applications.
The specification number matters because Rehlko/Kohler produced numerous CH730 engines with different crankshafts, wiring, controls, air cleaners and application-specific components.
A different CH730 specification should therefore not be assumed to be a direct replacement simply because it has the same displacement or horsepower rating.
Vermeer Engine Replacement Numbers
PA-CH730-0019 supersedes several older Vermeer-specific Kohler Command engine numbers, including:
Older Vermeer equipment or parts information may therefore reference one of these engine numbers instead of PA-CH730-0019.
Replacement for CH25 Vermeer Engines
PA-CH730-0019 is commonly used as the service replacement for older Vermeer-specific Kohler CH25 configurations.
For example, the older CH25-68652 Vermeer engine is superseded by PA-CH730-0019.
Older CH25 engines may have been marketed as 25 HP engines. The replacement CH730-0019 itself carries a current 23.5 HP rating.
CH730-0019 Crankshaft Dimensions
The PA-CH730-0019 uses a 1-7/16-inch diameter x 4.453-inch long horizontal crankshaft.
The shaft has a 3/8-inch keyway and the end is drilled and tapped 5/8"-18.
Do not substitute another CH730 solely by horsepower. The crankshaft diameter, length, keyway, mounting, wiring and controls must match the Vermeer application.
Vermeer Stump Grinder Replacement Engine
Replacement-engine catalogs specifically identify CH730-0019 for compatible Vermeer stump grinder applications.
This configuration includes the heavy-duty air-cleaner system, mechanical fuel pump, oil cooler and engine-mounted control arrangement associated with the Vermeer application.
Does PA-CH730-0019 Include a Muffler?
No. PA-CH730-0019 is specified without a muffler.
It also does not include an equipment fuel tank. Verify whether the existing Vermeer exhaust, fuel-system and installation components will be reused.
Before Ordering PA-CH730-0019
- Verify the original Kohler/Rehlko engine model and specification.
- Check for an older PA-68537, PA-68539, PA-68587, PA-68628, PA-68632 or PA-68652 engine number.
- Verify the Vermeer equipment model and serial number.
- Confirm the 1-7/16" x 4.453" horizontal crankshaft.
- Confirm the 3/8" keyway.
- Confirm the 5/8"-18 drilled and tapped crankshaft end.
- Verify the electrical and control connections.
- Confirm the existing muffler and exhaust arrangement.
