Product Description
The **Maxima V-Twin 100% Synthetic 3-Hole Service Kit** represents the peak standard of absolute powertrain protection for big-twin layouts. Maxima's advanced full synthetic engine oil utilizes a proprietary ester-infused compound matrix designed explicitly to withstand the extreme thermal loads generated by air-cooled pushrod engines, preventing heat shear and viscosity breakdown. This complete kit addresses all three primary fluid chambers by bundling dedicated high-film-strength primary lubricant to optimize wet-clutch hookup and heavy-duty 85W-140 transmission gear oil to minimize gear whine and protect sliding gear faces. Paired with a high-capacity, wind-tunnel-validated **HiFloFiltro HF171C Chrome Filter**, this maintenance pack keeps internal components pristine across extended service limits.
The Builder's Choice: Workbench 3-Hole Fluid Overhaul Procedures
Executing a comprehensive 3-hole service on a V-Twin power plant requires a professional **bench-assembly method** and strict layout segregation. Always verify the motorcycle is resting level on a secure stand before extracting the three separate drain fasteners. Take caution not to cross-contaminate fluid compartments; the engine crankcase, primary chaincase housing, and transmission box utilize highly specialized internal clearances that demand their exact respective fluids. Clean each magnetic drain plug tip thoroughly of residual friction wear particulates before sliding on the new premium replacement O-rings. When fitting the spin-on chrome HF171C filter container, pre-fill the filter cavity halfway with clean engine oil and apply a thin film of lubricant to the rubber base seal to guarantee smooth sealing torque without binding the seal face.
