The Cat 8X-5489 is a dedicated wiring sleeve for Caterpillar engine wiring harnesses. Its core function is to protect and position heavy-duty engine wiring harnesses as they pass through walls/cabins, suitable for C15/C18 models, ensuring insulation and signal stability under high temperature and vibration conditions. Key information is as follows:
Core Parameters
Item Details
Type: Engine wiring harness protective sleeve (with sealing lip), used for guiding, abrasion-resistant protection, and sealing when wiring harnesses pass through engine blocks, transmission housings, or firewalls, suitable for wiring harness insulation and positioning requirements under high pressure/high temperature conditions.
Compatible Models: Cat 980K/L/M loaders, D9T/R bulldozers, 777E/F mining trucks, etc., compatible with Cat C15, C18, and C32 engine wiring harness assemblies, used for through-cabin sealing assembly during engine overhauls and wiring harness replacements.
Material and Process: Base material: Modified nylon PA66 (25% glass fiber reinforced), temperature resistance -40℃ to… 150℃; Sealing lip: Fluororubber (FKM), oil and chemical corrosion resistant; Surface: Matte black, UV aging resistant; Inner wall: Smooth coating, reduces harness wear.
Key Dimensions: Inner diameter 25mm (0.984 inches), outer diameter 38mm (1.496 inches), length 50mm (1.969 inches), sealing lip diameter 26-28mm (adapts to harness outer diameter), flange diameter 45mm (4 M6 mounting holes evenly distributed), weight approx. 0.12kg (0.265 lbs).
Installation Requirements: Flange face mates with mounting base gasket (nitrile rubber), bolt preload torque 8-10 N·m, sealing lip must be coated with Cat-specific silicone grease, suitable for harness outer diameters 22-26mm, ensuring sealing and protection.
Functions and Suitable Scenarios:
Core Function: Provides drive-through guidance and wear-resistant protection for engine harnesses, isolating oil, dust, and moisture through the fluororubber sealing lip to prevent short circuits caused by harness insulation wear. / Circuit breaker, suitable for heavy equipment vibration, high temperature, and oil contamination conditions, ensuring stable signal/power transmission between the ECU and sensors/actuators.
Suitable scenarios: Used to replace aged/damaged wiring sleeves when engine wiring harnesses experience aging, insulation damage, oil/dust leaks at the through-cabin point, signal interference, etc., suitable for engine wiring harness overhauls and through-cabin sealing system maintenance needs.
Performance characteristics: Glass fiber reinforced PA66 substrate + fluororubber sealing lip, combining high strength, high temperature resistance, and chemical corrosion resistance, suitable for harsh engine compartment conditions, with a service life ≥5000 hours.
Smooth inner wall coating + adaptive sealing lip design reduces wiring harness friction loss and accommodates wiring harnesses of different outer diameters, improving assembly versatility and sealing reliability.
Flange with mounting holes + gasket design, easy installation, allowing for quick sealing and fixation at the through-cabin point, reducing assembly time.
