Troubleshooting Kohler Command Crankcase Breather Issues: A Comprehensive Guide

Kohler Command engines may experience a crankcase breather problem due to aged or worn gaskets, excessive valve cover pressure, or incorrect valve clearance.

Kohler Command Crankcase Breather Problems

Kohler Command engines are renowned around the world for their durability and reliability. However, their crankcase breather can sometimes give rise to a range of problems. These issues include poor fuel economy, hard starting, smoke or exhaust odors, excessive engine vibration, excessive oil consumption and poor acceleration. To ensure that your engine runs as smoothly and efficiently as possible, it is important to diagnose and fix any crankcase breather problems. This article will discuss the causes of crankcase breather issues on Kohler Command engines, how to diagnose them and the key solutions.

Kohler Command Crankcase Breather- Definition

A crankcase breather is a device that is used to ventilate the crankcase of an internal combustion engine. This device is typically found on small engines, such as those found in lawn mowers and other outdoor power equipment. The purpose of the crankcase breather is to allow excess air to escape the crankcase and prevent a buildup of pressure in the crankcase. This can help prevent oil leakage and engine damage that can occur due to excessive pressure build-up.

Diagnosing Problems

Diagnosing problems with the Kohler Command crankcase breather is relatively straightforward. The first step in diagnosing any issue with a Kohler Command engine should be visual inspection of the engine and surrounding parts. Check for any signs of leaking oil or other fluids, as this can indicate a problem with the crankcase breather or related components. If no leaks are present, then it may be necessary to perform an additional check for clogged air filter or blocked breather hoses.

Common Crankcase Breather Problems

Fouled air filters and clogged breather hoses are two of the most common problems associated with Kohler Command engines. A fouled air filter will restrict airflow into the engine, causing poor performance and reduced fuel efficiency. Clogged breather hoses can also lead to poor performance by preventing excess air from escaping the crankcase, which can lead to excessive pressure buildup in the crankcase and potential engine damage.

Kohler Command Engine Maintenance

Regular maintenance is key to getting optimal performance from your Kohler Command engine. Make sure to check your air filter regularly as this should be replaced at least once a year or more often if needed. Additionally, check your breather hoses for any signs of blockage or damage that could prevent proper ventilation of the crankcase.

Signs of a Malfunctioning Kohler Command Crankcase Breather

If your Kohler Command engines crankcase breather is not functioning properly, you may notice reduced fuel efficiency and diminished power output from your engine when compared with normal operation levels. These symptoms may indicate a malfunctioning crankshaft breather or related components that need attention immediately in order to ensure proper operation of your Kohler Command engine.

Potential Causes for Kohler Command Crankcase Breather Malfunction

Low quality air filters, damaged breather hose connections, or other issues related to ventilation components could be potential causes for a malfunctioning Kohler Command crankshaft breather system. It is important to inspect each component carefully when diagnosing any issue with your crankshaft breathing system in order to identify any problems that need attention before they cause major damage or costly repairs down the line.

How to Troubleshoot a Kohler Command Crankcase Breather System

Troubleshooting a Kohler Command crankcase breather system requires inspecting the air filter and hoses for clogs or damage and then replacing any damaged components as necessary. It is important to regularly maintain engine components to prevent crankcase breather problems from occurring in the first place. The manufacturer’s recommendations should be followed when replacing the air filter.

Kohler Burnt Oil Solutions for Reduced Performance Issues

When experiencing reduced performance issues due to burnt oil, several solutions can be applied. Checking the oil level regularly is essential, as well as checking the piston rings for carbon build-up. Spark plugs should also be checked to see if oil is burning and the intake manifold and carburetor should be cleaned out if necessary. Increasing fresh oil flow to the piston can be done by cleaning the PTO face, adjusting PTO lock nut tension left and right, checking exhaust manifold bolts, thrust washers and flywheel bolts, and inspecting head gasket, exhaust port, and valve seat.

Ways to Prevent Kohler Command Crankcase Breathers Problems

In addition to regular maintenance of engine components and replacing air filters according to manufacturer’s recommendations, there are other ways to prevent crankcase breather problems from occurring in the first place. Cleaning out all hoses with compressed air is recommended at least twice a year or more frequently depending on usage. Checking all connections regularly will also help spot any potential issues before they become more serious problems. Maintaining proper lubrication of all moving parts is key in order for them to work efficiently without excessive wear or tear.

FAQ & Answers

Q: What is a Kohler Command Crankcase Breather?
A: The Kohler Command Crankcase Breather is a device that helps reduce pressure and heat build-up inside the crankcase of an engine. It works by allowing air from the outside to enter the crankcase, thereby reducing pressure and keeping the engine cool.

Q: What are some common crankcase breather problems?
A: Common crankcase breather problems include fouled air filters, clogged breather hoses, or damaged breather hose connections. These issues can lead to reduced fuel efficiency, diminished power output, or other engine performance issues.

Q: How can I prevent Kohler Command Crankcase Breathers problems?
A: To prevent Kohler Command Crankcase Breathers problems, regularly maintain your engine components, replace the air filter as recommended by the manufacturer, and check oil levels regularly. Additionally, inspect the air filter and hoses for clogs or damage on a regular basis.

Q: What are some Kohler Burnt Oil Solutions for Reduced Performance Issues?
A: Some solutions for reduced performance due to oil burning include checking your oil level regularly, checking your piston rings for carbon build up, checking your spark plugs to see if oil is burning, cleaning out your intake manifold and carburetor, increasing fresh oil flow to piston by cleaning PTO face, adjusting PTO lock nut tension left and right, checking exhaust manifold bolts, thrust washers and flywheel bolts; inspecting head gasket exhaust port and valve seat.

Q: What are some signs of a malfunctioning Kohler Command Crankcase Breather?
A: Signs of a malfunctioning Kohler Command Crankcase Breather include reduced fuel efficiency or diminished power output. Additionally you may experience other engine performance issues such as decreased acceleration or difficulty starting the engine.

The Kohler Command Crankcase Breather is a reliable and durable part of the engine, but there are a few issues that can arise in its operation. The most common issue is an oil leak which can be caused by a number of factors, such as a loose or damaged breather hose, incorrect installation, or a faulty crankcase breather valve. In addition, the crankcase breather can become clogged with dirt or debris over time which can lead to poor performance and overheating. To avoid these potential problems, it is important to regularly inspect the crankcase breather and replace any defective parts.
