Technical Brief: DZ70 Crankshaft

The YS Engine YSG7015 crankshaft serves as a direct spare for the DZ70 series of RC nitro engines. As a precision-machined steel component, it transmits piston force into rotational output while preserving the DZ70's designed geometry and timing.

Below are practical checks and simple installation considerations, plus the crank's role when rebuilding or tuning an engine. Always check bearing health and engine layout before fitting a new crank to avoid imbalance or premature failure.

Specifications

  • Item: Crankshaft
  • Material: Steel
  • Model Number: YSG7015
  • Compatibility: DZ70 engine series

Intended as a spare for DZ70 engines, this crankshaft restores correct rotating geometry during rebuilds and supports predictable tuning when paired with appropriate bearings and seals.

What pre-install checks should I carry out?

Measure journals and inspect crank faces for damage, then compare part number YSG7015 to your engine diagram. Verify clearances and check for any signs of previous overheating or distortion.

Can I balance the crank at home?

Simple static balancing can be attempted with basic tools, but dynamic balancing requires specialist equipment. For best results, have balancing done by a workshop if precise tuning is needed.

Does the steel construction reduce flex or wear?

Steel offers strong resistance to bending under load, which helps maintain timing and geometry. Long term wear still depends on bearing condition and lubrication.

How often should I service after fitting a new crank?

Inspect seals and bearings after the first few runs, then follow a regular maintenance schedule based on engine hours and use conditions to ensure continued reliability.
