Abstract
Embodiments of a cold start lubricant distribution system include a lubricant distribution circuit, which fluidly interconnects first and second actively-lubricated work vehicle assemblies onboard a work vehicle. A flow divider section is included in the lubricant distribution circuit and through which lubricant flow is apportioned between the first and second actively-lubricated work vehicle assemblies. A lubricant supply pump is further located in the lubricant distribution circuit upstream of the flow divider section. The cold start lubricant distribution system further includes a lubricant flow modification assembly operably in a cold start mode. When operating in the cold start mode, the lubricant flow modification assembly reduces a volume of lubricant flow supplied to the first actively-lubricated work vehicle assembly through the flow divider section relative to a volume of lubricant flow supplied to the second actively-lubricated work vehicle assembly through the flow divider section.
