CAT 315 Series Excavator Top Roller OEM Replacement 41-7345
Product Overview
This carrier top roller is a 1:1 OEM direct replacement for CAT 315, 315B, 315C series excavators, matched with official part number 41-7345. No cutting, drilling or other secondary modification is required during replacement. It adapts to long-term heavy-duty onsite operation and solves common undercarriage running abnormalities of CAT 311 series excavator fleets.
Item Specification
OEM Part Number 41-7345
Applicable Excavator Model CAT 315 / 315B / 315C Excavator
Machining Tolerance ±0.01mm CNC ultra-precision machining
Heat Treatment Process Overall quenching + stress relief tempering
Applicable Working Scenarios Muddy construction site, gravel quarry, road renovation, rough earthmoving terrain
Installation Type Plug-and-play OEM direct replacement
Applicable Working Environments
CAT 311 series excavators are widely used for municipal engineering, slope trimming, small-scale quarry and road repair projects. Long-term muddy water immersion, continuous gravel friction and frequent walking impact will cause ordinary aftermarket top rollers to produce track shaking, track sagging, internal seal oil leakage and shaft stuck. This roller is manufactured to fit medium-load working conditions and maintain stable long-term operation.
Core Production Technology
Adopt one-piece integral forging steel blank to avoid structural crack risks. Standard dual heat treatment is adopted: quenching improves surface hardness to resist abrasive wear from sediment and gravel; tempering eliminates internal machining residual stress to prevent roller shell rupture under repeated impact loads. All mounting holes and matching contact surfaces are processed by high-precision CNC machine tools, with overall machining error controlled within 0.01mm, fully matching original factory installation dimensions.
On-site Installation Steps
  1. Raise the excavator track with a hydraulic jack to separate the track from the ground and release partial track tension
  2. Remove fixing bolts of the old top roller, take out the damaged roller and clean mounting base dust and sediment
  3. Place the new OEM top roller in the original installation position, align reserved bolt holes accurately
  4. Lock all fixing bolts with standard torque, reset track tension and test track idle running
  5. Check no abnormal vibration or friction noise to finish installation
Optimized On-site Operation Performance
  • Precise dimensional matching avoids track deviation and walking vibration during daily operation
  • Reinforced floating seal structure blocks muddy water and dust ingress to prevent oil leakage
  • Complete heat treatment process enhances impact resistance to reduce roller shell fracture failure
  • Direct plug-and-play installation cuts on-site maintenance time and labor cost
Real Customer Cooperation Case
An Asian local equipment leasing company owns 15 sets of CAT 315/315B series excavators. Previously equipped with ordinary aftermarket top rollers, most parts failed within 700-850 working hours due to incomplete heat treatment. After switching to our OEM-standard top rollers, all rollers run steadily over 1800 working hours without oil leakage or shell damage, reducing annual undercarriage maintenance expenses by 34%.
Frequently Asked Questions
Q1: Does this top roller fit 315, 315B and 311C excavators?
A: Yes, part number 41-7345 is compatible with three models above, full consistent with original mounting size, no extra adjustment required.
Q2: What is the difference between our products and generic aftermarket rollers?
A: Most low-cost aftermarket rollers skip tempering process and have dimensional tolerance over 0.05mm. Our dual heat treatment and 0.01mm high precision ensure more stable performance in complex construction sites.
Q3: Can you provide batch inspection documents for bulk orders?
A: Yes, we can provide official heat treatment test reports and dimensional inspection reports to support customers' local quality inspection.
