As the core power component of the lubrication system for 4-stroke motorcycle engines, the oil pump undertakes core functions including pressurized oil delivery, circulating heat dissipation, mechanical friction reduction and oil pressure stabilization. It directly determines the service life of key engine parts such as camshaft, crankshaft, connecting rod and cylinder block, and is also one of the high-failure and high-maintenance wearable core parts for Yamaha LC135 4S models. Targeting four common defects of original LC135 4S oil pumps: insufficient idle oil supply, high-temperature oil pressure attenuation, fast gear wear and pump body oil leakage, CPO COOL POWER has independently developed a customized oil pump exclusive for LC135 4S. Adopting 1:1 original mold calibration and plug-and-play upgrade design, it adapts to full-scenario riding including daily commuting, mountain road riding and mild modification in Southeast Asia, providing long-term and stable lubrication protection for LC135 4S engines.CONTACT US!
1. Brand Introduction: CPO COOL POWER Professional Motorcycle Oil Supply Parts Brand
CPO COOL POWER has years of experience in R&D and production of precision oil supply and lubrication parts for two-wheeled motorcycles. Focusing on the complete vehicle matching and after-sales maintenance market of mainstream 4-stroke motorcycle models in Southeast Asia, the brand has built production lines with full-process testing including oil pressure air tightness test, material wear resistance test and working condition simulation test. All CPO COOL POWER oil pumps meet original assembly parameters, balancing cost performance and durability. Applicable for complete vehicle factory supporting, motorcycle parts retail, repair shop bulk replacement and cross-border parts supply, all products comply with Southeast Asian motorcycle parts access standards. Committed to solving lubrication and oil supply failures of mainstream models, the brand has gained long-term cooperation recognition from global motorcycle parts distributors.
2. Precise Fit: Exclusive for LC135 4S, Multi-model Universal Compatibility
This customized oil pump is exclusively developed for LC135 4-speed 4-stroke engines, distinguished from 2-stroke and 5-speed dedicated oil pumps. With gear ratio, oil pressure, mounting hole position and shaft diameter fully complying with original part code 1S7-E3300-00 specifications, it requires no grinding, pipeline modification or oil pressure adjustment, realizing direct plug-and-play installation on original vehicles.

3. Solve Pain Points: Eliminate Common Failures of Stock LC135 4S Oil Pumps
Ordinary original and aftermarket LC135 4S oil pumps have widespread service defects under high-temperature and dusty road conditions in Southeast Asia. CPO COOL POWER optimizes structural technology in a targeted manner to eliminate all common failures:
Insufficient Idle Lubrication: Ordinary pumps feature low idle oil output, leading to insufficient cylinder head oil supply during idle running and low-speed climbing, further causing camshaft abnormal noise and dry friction damage. This product optimizes inner rotor tooth volume to realize stable idle oil supply, delivering engine oil to the cylinder head directly at low speed.
High-speed Oil Pressure Attenuation: Ordinary pumps suffer rapid oil pressure drop at high engine speed, worsening circulating heat dissipation and causing engine scuffing in summer. This product maintains constant oil pressure output with 20% higher oil supply flow than original parts, adapting to high-load riding.
Worn and Skipping Gears: Gears of ordinary pumps made of common steel wear fast, resulting in uneven oil supply and pressure relief caused by gear skipping. This pump adopts vacuum quenched alloy steel rotors for smooth meshing and high wear resistance, avoiding oil supply interruption.
Pump Body Joint Oil Leakage: Ordinary pumps adopt simple sealing technology, with gaskets aging and leaking under high temperature. This integrated die-cast pump body is equipped with high-temperature resistant fluororubber sealing gaskets for long-term oil leakage and pressure relief prevention.
4. Core Manufacturing Process & Performance Advantages
Supported by CPO COOL POWER precision manufacturing technology, the LC135 4S oil pump is upgraded in material, structure and precision to adapt to long-term high-frequency riding conditions:
1. High-strength Material for Harsh High-temperature Road Conditions
The pump body is integrally die-cast with high-chromium alloy without pores or trachoma, featuring strong compression and deformation resistance. Inner and outer rotors are made of vacuum quenched alloy steel with standard hardness, great corrosion resistance to engine oil. Suitable for tropical high-temperature and sandy road conditions in Southeast Asia, its wear resistance is 42% higher than ordinary aftermarket oil pumps, greatly extending service life.
2. CNC Precision Tooth Grinding for Silent and Uniform Oil Supply
Adopting 5-axis CNC precision machined crescent inner tooth structure, the tooth gap tolerance is controlled within micron-level industry standard for uniform rotor meshing and silent operation. It delivers linear and stable oil supply without oil shortage at low speed or pressure relief at high speed, balancing lubrication efficiency under full engine speed and reducing engine overhaul risks.
3. Original Calibrated Oil Pressure Compatible with Original Oil Circuit
It fully replicates the original oil pressure parameters of LC135 4S, requiring no modification to original oil passages, filters and pressure regulating structures, without breaking the original engine lubrication logic. Equipped with positioning pins for accurate alignment, it features high installation fault tolerance for quick replacement even for novice maintenance workers.
4. Full Factory Inspection for Reliable Quality
Every LC135 4S oil pump passes three strict factory tests: air tightness test, high-low speed oil pressure test and long-term endurance operation test to eliminate defective products. Ideal for bulk purchase by repair shops and individual vehicle replacement, it delivers far more stable quality than ordinary aftermarket parts.
