Used 370B Backhoe Buyer’s Guide
When shopping for a used 370B backhoe you’re targeting a reliable workhorse known for solid hydraulics and a robust Caterpillar-engineered chassis. To help you make an informed purchase, here’s a concise breakdown of key considerations, inspection checkpoints, and value-ensuring tactics.
Why Choose the 370B?
- Purpose-built performance: The 370B was configured for heavy excavation, loading, and material handling; its lifting capacities and reach are well-balanced for jobsites needing both digging depth and loading strength.
- Proven durability: Caterpillar built it with a frame that resists flex and a boom/stick designed for repetitive motion, so even older units can keep earning if properly maintained.
- Parts availability: Since this model shares components with other Caterpillar machines, replacement parts are still accessible, keeping downtime manageable.
Inspection Checklist
To respect the used-market variability, examine these areas thoroughly:
- Engine health
- Listen for smooth idle and check for excessive smoke (black or blue can imply turbo/wear issues).
-
Review service records: consistent oil, coolant, and hydraulic fluid changes reveal conscientious operators.
-
Hydraulic system
- Inspect for leaks around cylinders, hoses, and fittings—minor seepage may be tolerable, but heavy drips or included contaminants warrant caution.
-
Pump performance should remain steady; any jerking or lag during boom/swing operations often points toward internal wear.
-
Undercarriage & frame
- Look for bent pins, cracked welds, or uneven wear in the boom and dipper stick.
-
Track and tire condition (if convertible) gives a sense of past jobsite environments and maintenance habits.
-
Cab & controls
- Functional gauges, switches, and safety interlocks reduce future repair scope.
-
Check seat adjustment, visibility, and whether the cab is sealed against dust—this reflects attention to operator comfort and machine hygiene.
-
Attachments and versatility
- Verify that the quick coupler (if equipped) operates cleanly.
- Evaluate included buckets, thumbs, or hydraulic hammers for wear and attachment integrity.
Pricing Insights
The market value for a 370B depends heavily on hours, upkeep, and geography. Machines with fewer than 8,000 hours and comprehensive service histories often keep better resale value. Expect price ranges to vary, but prioritize quality over the lowest sticker—the correct machine avoids a cascade of repair bills.
Documentation & History
Always request:
– Serial number verification: Confirms authenticity and helps track outstanding recalls or campaigns.
– Maintenance logs: Look for scheduled services, hydraulic overhauls, and documented wear part replacements.
– Operator usage type: Machines used primarily for trenching tend to wear differently than those used for heavy loading; understanding past workload helps anticipate your maintenance needs.
Post-Purchase Prep
After purchase:
– Flush and replace all fluids even if recent service is documented—this resets your baseline and removes residual contaminants from uncertain prior usage.
– Install fresh filters (fuel, air, hydraulic) to ensure clean delivery systems before the machine goes into your fleet.
– Consider a certified inspection or reconditioning plan, especially if you rely on the machine for critical timelines.
By aligning your evaluation with these professional benchmarks, you’ll secure a used 370B backhoe that delivers reliable digging power with manageable ownership costs.
