Precision Timing for Enhanced Engine Protection

In a heavy-duty diesel engine, even a fractional error in camshaft timing can lead to catastrophic engine damage, such as valves striking the pistons. Utilizing quality engine parts from IMARA provides the engine protection necessary to prevent such engine failure.

A well-maintained camshaft is also critical for managing engine oil consumption. When lobes wear down, the valves do not open fully, leading to poor combustion and a potential increase in burning oil. Our precision-ground camshafts ensure that your engines running in the field maintain the correct valve lift and duration, which directly improves fuel economy and makes your machine more fuel efficient.

Our Range of Precision-Engineered Camshafts

We supply camshafts for major equipment brands, matched precisely to your specific engine type and serial number to ensure OEM-standard performance.

1. Chilled Cast Iron Camshafts

Our chilled cast iron camshafts offer incredible surface hardness on the lobes. This is essential for preventing engine wear caused by the constant friction between the cam and the lifters. These units are designed to handle high pressure valve springs without degrading, ensuring long term durability.

2. Precision-Ground Lobes to Reduce Friction

The interaction between the camshaft and the valvetrain must be smooth to minimize parasitic loss. Our camshafts feature polished lobes that reduce friction, allowing the engine to convert more energy into mechanical energy. This precision helps maintain a stable oil level by reducing the heat generated at the top of the cylinder head.

3. Optimized Valve Timing for Power Output

A precision camshaft ensures that the combustion chambers are filled and emptied at the perfect microsecond. This optimization increases your power output and ensures that motor oils can effectively lubricate the valvetrain without being compromised by excessive heat from escaping combustion gases.

Maximizing Camshaft Life and Lube Integrity

The longevity of a camshaft is heavily dependent on the quality of your lubrication system. Because the cam-to-follower interface is a high-pressure point, the following maintenance steps are vital:

• Oil Viscosity Management: Ensure you are using the correct oil viscosity to maintain a protective film on the cam lobes. Whether using conventional oil or high-quality engine oil, the lubricant must stay stable at high temperatures.

• Filtration: A clean oil filter is essential. Small contaminants in the oil can act as an abrasive, quickly wearing down the cam lobes and leading to excessive oil consumption.

• Oil Pump Performance: A consistent flow from the oil pump ensures that the overhead assembly is never starved of lubricant, preventing localized engine wear.

Technical Support and Precise Fitment

Because camshaft profiles vary significantly across diesel engines, getting an exact match is non-negotiable. An incorrect profile can lead to poor fuel economy or even mechanical interference. At IMARA Engineering Supplies, we use your engine serial number to provide high quality parts that fit perfectly the first time.

Our technical experts understand how the camshaft interacts with the connecting rods and crankshaft to create a synchronized power plant. By providing the right engine parts, we help you avoid "Machine Off Road" (MOR) delays and keep your engine oil consumption within factory specifications.
