Product Detail

Product Description: Pinion Shaft 178-15-13240 for Shantui SD22/SD32 Bulldozer Transmission

The Pinion Shaft 178-15-13240  is Shantuicomponent engineered for the transmission systems of Shantui SD22 and SD32 series crawler bulldozers, as well as other compatible Shantui models including SD16, SD23, SD42, SD52 and SD90. This precision-machined shaft serves as a spiral bevel pinion shaft — a critical element within the bulldozer‘s transmission assembly, where it functions as the driving gear that transmits rotational torque from the transmission to the mating spiral bevel gear (crown wheel) in the final drive system.

Compatible Shantui Models

The 178-15-13240 Pinion Shaft is compatible with the following Shantui models:

Model SeriesSpecific Models
SD22 SeriesSD22, SD22S, SD22R, SD22C, SD22D, SD22E
SD32 SeriesSD32, SD32-5
Other SD SeriesSD16, SD23, SD42, SD52, SD90 (partial compatibility; verify fitment)

Related Components in the Transmission Assembly

Within the SD32 transmission assembly, the 178-15-13240 pinion shaft works alongside several other transmission components:
