CAT 597-6298 Shroud Retainer

CAT 597-6298 is a Caterpillar engine turbocharger cover retainer used to secure the turbocharger heat shield, preventing it from loosening or shifting. It is compatible with heavy-duty diesel engines such as the Cat C13/C15/C18. The following is structured technical and application information.

Core Technical Parameters

Item Details
Basic Attributes Model 597-6298, type is a turbocharger cover mounting clip, material is stainless steel 304 (high temperature resistance 800℃), surface treatment is polished and passivated, single weight is about 0.12 kg, installation method is bolt fastening, suitable cover thickness 3-5 mm, matching bolt type M8×20 (8T-5678)

Key Dimensions Clamping width 15 mm, clamping diameter 80 mm, bolt hole center distance 60 mm, clamping arm length 40 mm, chamfer 1×45°, suitable cover outer diameter 80 mm, working temperature -40℃ to +800℃

Suitable Engines and Locations Suitable for Cat C13 ACERT, C15 ACERT, C18 ACERT engines, installed on both sides of the turbocharger heat shield, 4 units per engine This component is used to secure the turbocharger housing to the turbocharger casing, preventing vibration or detachment.

Performance Parameters: Tensile strength ≥520 MPa, Yield strength ≥205 MPa, High temperature resistance 800℃, Corrosion resistance IP65, Service life ≥5000 hours, Tightening torque 25-30 N・m

Structural and Performance Advantages:

Stainless Steel Material: 304 stainless steel possesses excellent high temperature and corrosion resistance, suitable for the high-temperature environment near the turbocharger, preventing rust or deformation under prolonged high temperatures.

Dedicated Clamping Structure: The clamping arm design conforms to the curved surface of the casing, providing uniform clamping force and preventing excessive localized stress that could lead to deformation. It also includes a thermal expansion gap to prevent the casing from jamming at high temperatures.

Bolt Fastening Design: Secured with M8 bolts, easy to install and disassemble, reusable, with a precise tightening torque to ensure reliable fixation and prevent loosening due to vibration.

High Versatility: Compatible with various Cat heavy-duty engine turbocharger casings, eliminating the need for customization and reducing procurement and inventory costs.

Installation and Maintenance Points

Installation Procedure: Clean the surface of the cover and retainer, checking for deformation and cracks; clamp the retainer in the designated position on the cover, aligning the bolt holes; install the M8×20 bolts, tightening with a torque wrench to 25-30 N·m; check that the cover is securely fixed, without looseness or wobbling.

Maintenance Cycle: Check the retainer’s tightness every 1000 hours, retightening any loose bolts immediately; check the wear of the contact area between the retainer and cover every 2000 hours, replacing if deformation or cracks are found; during engine overhaul, it is recommended to replace all retainers to ensure safe operation.

Common Faults and Solutions: Loose retainers are often due to insufficient bolt torque, requiring retightening to the standard torque; deformed retainers are often due to obstructed thermal expansion of the cover, requiring adjustment of the installation position and allowing for clearance; corrosion of retainers is often due to prolonged high temperatures or contact with corrosive media, requiring replacement with stainless steel retainers.
