Essential Wear Parts for Bobcat Excavators – Full Model Guide

Bobcat excavators are among the most popular compact and mid-size machines in construction, landscaping, utility, and agricultural applications. Covering the E10, E26, E32, E35, E42, E50, E85, E88, and E145 series, these excavators are built for durability—but continuous operation in harsh conditions leads to predictable wear on key components. This professional guide outlines the most common wear parts, failure symptoms, replacement intervals, and maintenance best practices to keep your Bobcat running efficiently.

Common Bobcat Excavator Model Range

• E10–E20: Mini excavators (1–2 ton) for small-scale digging and indoor work
• E26–E35: Compact excavators (2.6–3.5 ton) – the most widely used models
• E42–E50: Mid-size excavators (4–5 ton) for construction and utility projects
• E85–E88: Heavy-duty compact excavators (8–8.8 ton) for demanding excavation
• E145: Large compact excavator (14.5 ton) for heavy construction and site development

1. Bucket & Front Attachment Wear Parts

Bucket teeth, adapters, cutting edges, and side cutters are the most frequently replaced parts due to constant abrasion and impact.

• Bucket teeth & adapters: Wear down in rocky soil, concrete, and demolition environments
• Cutting edges & side cutters: Protect the bucket body from excessive wear
• Pins & bushings: Connect boom, arm, and bucket; develop slack after prolonged use

Recommended replacement: 200–800 hours depending on working conditions.

2. Undercarriage Wear Parts

The undercarriage supports the entire machine and suffers heavy abrasion in rough terrain.

• Rubber or steel tracks
• Top and bottom track rollers
• Front idlers and rear drive sprockets
• Track adjusters and tension springs

Typical lifespan: 1,500–6,000 hours based on track type and ground conditions.

3. Hydraulic System Wear Parts

Hydraulic components control lifting, digging, and swinging functions.

• Hydraulic filters (suction, return, pilot)
• Cylinder seal kits for boom, arm, and bucket
• O-rings, gaskets, and hydraulic hose assemblies

Replace filters every 500–1,000 hours; repair seals when leaks appear.

4. Engine Wear Parts

Most Bobcat excavators use Kubota or original Bobcat diesel engines. Key wear parts include:

• Oil, fuel, and air filters
• Drive belts for alternator and cooling fan
• Gaskets, oil seals, and valve components
• Sensors for oil pressure, temperature, and speed

Standard maintenance interval: Filters every 250–500 hours.

5. Cooling & Electrical Wear Parts

• Water pumps and thermostats
• Radiator hoses and clamps
• Batteries, cables, and starter components

These parts often degrade from heat, vibration, and moisture over time.

Maintenance & Replacement Interval Summary

• Bucket teeth & cutting edges: 200–800 hours
• Pins & bushings: 1,000–2,000 hours
• Tracks & undercarriage: 1,500–6,000 hours
• Filters & fluids: 250–1,000 hours
• Engine overhaul components: 8,000–12,000 hours
