Service Crankshaft for GT15HZ Engines

This crankshaft is an RC replacement component identified by model number OS28152000 and intended specifically for GT15HZ series engines.

The part converts piston reciprocation into rotational output and contributes to crankcase balance and timing. As a direct-fit replacement it is manufactured to match the dimensional interfaces of GT15HZ crankcases so no chassis modification should be required for installation.

Installation notes: check the crankcase bearing seats and mating surfaces carefully prior to fitment, confirm correct endplay and bearing seating after assembly, and carry out the engine manufacturer's recommended run-in procedures for any new rotating component. During routine servicing this crankshaft can be swapped to return worn engines to their original running characteristics.

Fit this crankshaft when overhauling GT15HZ nitro engines to preserve mechanical integrity and maintain predictable tuning behavior during setup and service.
