Description
Overview:
The Crankshaft Pinion for Jap Model 55 Twin industrial engines is a genuine Jap spare part made for reliable power transmission within the crankshaft gear train. Supplied under MPN 16961V (also OEM No. 16961), it is a durable metal gear designed to mesh cleanly with the matching components on the Jap 55 Twin and 55TWIN engines. It helps maintain smooth drive, supporting correct operation and extending service life when replacing a worn or damaged original. This is unused old stock for vintage models, so the surface may show age-related tarnish from storage, which does not affect performance. Suitable for routine maintenance or full rebuilds, it offers straightforward fitting for competent DIY users and professional mechanics working on older industrial machinery.
Key Features:
- Genuine Jap part for assured compatibility and reliability
- MPN 16961V; OEM No. 16961 for precise identification
- Durable metal construction for long service life in industrial use

- Suitable for workshop installation with standard tools and methods
- Helps restore performance during engine rebuilds and repairs
- Chosen by tradespeople and DIY users maintaining legacy plant
Typical Applications:
Service replacement during maintenance or overhaul of Jap Model 55 Twin engines used on older plant and machinery. Common in applications such as pumps, generators, cement mixers, small construction equipment, and agricultural implements. Ideal when the original crankshaft gear is worn, chipped, or noisy, to restore reliable drive and protect mating gears.
