Cummins Spring Pack Cover 3065376 For KTA38

Crafted from high-grade cast aluminum alloy (A356-T6), this spring pack cover offers exceptional strength-to-weight ratio and corrosion resistance. The CNC-machined housing ensures precise fitment, while a reinforced neoprene gasket (70-75 Shore A hardness) provides a reliable seal against oil leaks and particulate ingress. The aluminum body features heat-dissipating fins to manage thermal loads from engine operation, and the interior is coated with a ceramic-based thermal barrier to reduce heat transfer to adjacent components. Stainless steel fasteners (Grade 304) secure the cover, preventing rust in humid or marine environments.

This component is tailored for Cummins KTA38 engines deployed in extreme-duty cycles. Key applications include:

It is also compatible with retrofit kits for legacy KTA38 engines in agricultural and oilfield machinery.

: Finned aluminum design lowers spring pack temperatures by 15–20%, reducing valve spring fatigue.

: Rubber-isolated mounting points absorb shock loads up to 25 Gs.

: IP66-rated protection against dust, moisture, and oil splash.

: Powder-coated exterior withstands pH 3–11 chemical exposure.

: Rated for 10,000+ hours under continuous operation at ambient temperatures up to 150 degree (302 degree F).

Engineered for tool-free installation, the cover integrates seamlessly with KTA38 spring packs using pre-aligned bolt holes. The gasket's compression-fit design eliminates the need for adhesives, reducing downtime during replacements. Compatibility includes KTA38-G3, G5, and G6 variants, with optional shim kits (sold separately) for fine-tuning clearance. OEM-certified dimensions ensure no interference with adjacent rocker arms or injectors. A maintenance interval of 1,500 hours is recommended for gasket inspection, though the cover itself requires no routine servicing.
