Kubota Wg1605 Oil Filter
The Kubota WG1605 engine uses an oil filter cartridge to maintain clean engine oil. The oil filter for this engine is a spin-on type cartridge that can be easily replaced during routine maintenance.
Key details about the WG1605 oil filter include:
The filter cartridge has a part number of W21ES O1600, which replaces the older part number 16271-32092.
It is designed specifically for Kubota engines to ensure proper filtration and engine protection.
The filter should be replaced at regular service intervals as specified in the engine maintenance schedule, typically every 200 hours of operation or annually, whichever comes first.
When replacing the filter, it’s important to apply a light coat of clean engine oil to the gasket before installation. The new filter should be tightened by hand until the gasket contacts the mounting surface, then turned an additional 3/4 turn to ensure proper sealing.
After installing a new oil filter, it’s crucial to check the engine oil level and top up if necessary, as some oil will be retained in the new filter.
The WG1605 oil filter is compatible with various Kubota engine models beyond just the WG1605, including several excavators, tractors, and other industrial equipment powered by Kubota engines.
Proper oil and filter maintenance is essential for the longevity and performance of the WG1605 engine, helping to remove contaminants and ensure clean oil circulation throughout the engine.
Kubota Wg1605 Oil Type
The Kubota WG1605 engine requires high-quality engine oil to ensure proper lubrication and protection of its internal components. For this engine, Kubota recommends using API (American Petroleum Institute) classified SJ or higher grade engine oil.
The recommended viscosity for the WG1605 engine is:
SAE 10W-30 for general use in most temperature conditions
SAE 5W-30 for cold weather conditions or when ambient temperatures are consistently below 0°C (32°F)
SAE 15W-40 for high ambient temperatures, typically above 25°C (77°F)
When choosing the oil, it’s important to consider the operating conditions and ambient temperatures where the engine will be used. The multi-grade oils like 10W-30 provide good protection across a wide range of temperatures and are suitable for most applications.
For engines operating in severe conditions or under heavy loads, synthetic or semi-synthetic oils may offer better protection and longer service intervals. However, always consult the engine’s operation manual or a Kubota dealer for specific recommendations based on your operating conditions.
The oil capacity for the WG1605 engine is approximately 6.0 liters (1.6 U.S. gallons) when changing both the oil and filter. It’s crucial to maintain the correct oil level, which should be checked regularly using the dipstick.
Kubota recommends changing the engine oil and filter every 200 hours of operation or annually, whichever comes first. However, more frequent oil changes may be necessary in dusty environments or under severe operating conditions.
Remember to always use high-quality oil that meets or exceeds the API service classification recommended by Kubota to ensure optimal engine performance and longevity.
