Product Details
Weight: 4.00 kg
Flywheel Couplings - Diesel Engine to Hydraulic Pump (30-600HP)
Heavy-duty flywheel coupling system for driving hydraulic pumps straight off a diesel flywheel - drive plates, elastomer hubs and SAE pump mount plates.
Remember - a complete drive needs four parts: bellhousing + motor-side half + pump-side half + rubber element. This listing covers one of them; the others are linked below.
Use the dropdown to choose. All prices include GST.
Suits: Diesel engines with SAE 2-6 flywheel housings and 6-1/2in to 11-1/2in flywheels, driving SAE A/B/C/D pumps.

How to Choose
- Three parts: a drive plate bolted to the engine flywheel (pick by flywheel size 6-1/2in to 11-1/2in), a hub on the pump shaft (pick by flywheel size + pump shaft), and a pump mount plate (pick by engine SAE housing size + pump SAE flange).
- Flywheel size is stamped on the housing or measured across the bolt circle.
- 30-600HP diesel coverage. US made.
Technicians Advice
Centre the drive plate carefully - runout over 0.2mm TIR shows up as vibration at speed. Use grade 8.8 bolts with thread-locker into the flywheel. Grease the hub hex with moly paste at every service; a dry hex hammers itself oval. On repowers always confirm SAE housing size before ordering the mount plate - 4 and 5 look similar at a glance.
