Full Product Specifications: Waukesha BEARING FRONT 161309C
1. Basic Product Overview
Full Part Name: Waukesha 161309C Front Main Bearing
Product Type: Front crankshaft main bearing (1st main journal) with integrated thrust flange for axial load resistance
Brand Clarification:
Waukesha Engine: OEM genuine spare part for Waukesha gas/diesel engines. This component is an engine bearing, not the fluid processing bearings from Waukesha Bearings.
FRONT: Denotes the bearing fitted at the front end of the crankshaft, with one-piece integrated thrust axial load function.
Suffix "C" Definition: STD standard size (no undersized/oversized machining allowance, standard stock wall thickness 0.000").
Structure: Split two-piece bearing shell with positioning tang on one side, integrally cast thrust flange face
Temperature Resistance: Continuous operating temperature ≤135°C, instantaneous peak temperature 160°C; compatible with gas/diesel engine oil lubrication.
G265 generator sets, oilfield fracturing equipment, biogas power generation complete Waukesha units
Interchangeable part numbers for the same series: 161309 (base part), 161309C (STD standard size); undersized repair part suffixes: 161309-010, 161309-020
Wear Limit: Replace immediately when shell wall wear loss ≥0.008 in (0.2 mm); maximum allowable thrust face clearance 0.015 in
6. Key Assembly Specifications
Bearing Free Spread: Unassembled inner diameter is 0.004~0.007 in larger than block bore to ensure full contact and heat dissipation
Positioning Tang Alignment: Align tang with the oil supply slot in the crankcase, oil groove facing the engine internal lubrication gallery
Main Cap Bolt Torque: 190–210 ft-lb (258–285 N·m)
Complete Set Description: 161309C is a single front thrust main bearing shell. Full main bearing kit part number: OP2103 (5-piece complete main bearing set including 161309C front bearing)
7. Supplementary Remarks
Distinguish Confusing Similar Parts: Waukesha Cherry-Burrell pump front bearings do not use part number 161309C; PN 161309C exclusively applies to Waukesha internal combustion engine main bearings.
Order Identification Guide: C = STD standard size; suffix -10 = 0.010" undersize, -20 = 0.020" undersize repair bearings
