The Math Behind Preventive Maintenance
The average unplanned repair on a piece of construction equipment costs $4,200 in parts and labor. Add crew downtime ($400-$600/hour for a 4-man crew), emergency service premiums, and missed deadlines — the true cost of a single breakdown reaches $8,000-$12,000.
A preventive maintenance program catching that same failure before it happens costs $200-$500 in scheduled service. The math is not complicated: PM costs less. Every time.
Common Failures That PM Prevents
Cooling system failure — Hoses degrade, coolant loses effectiveness, and radiators plug with debris. A $50 hose replacement during PM prevents a $6,000 engine overheat repair.
Hydraulic system contamination — Dirty hydraulic fluid destroys pumps and cylinders. A $300 fluid and filter change prevents $8,000-$15,000 in hydraulic component replacement.
Fuel system degradation — Water in fuel, clogged filters, and worn injectors reduce power and eventually kill engines. PM catches water contamination before it reaches injectors.
Electrical failures — Corroded connections, worn alternators, and degraded batteries cause no-start conditions. PM identifies voltage drops and resistance issues before they strand a machine.
Undercarriage wear — On tracked machines, undercarriage components account for 50% of total maintenance cost. PM measures wear rates and schedules replacement before components damage each other.
PM Schedule Recommendations
Follow these intervals as a baseline. Adjust based on operating conditions — dust, heat, and heavy use accelerate wear.
| Interval | Service Items |
|---|---|
| Every 250 hours | Engine oil and filter, visual inspection, fluid levels, air filter check |
| Every 500 hours | Hydraulic filter, fuel filter, coolant test, battery test, belts and hoses |
| Every 1,000 hours | Hydraulic fluid sample and analysis, coolant flush (if needed), valve adjustment, injector inspection |
| Every 2,000 hours | Undercarriage measurement (tracked machines), turbo inspection, complete electrical system test |
| Annually | Full machine inspection regardless of hours, update maintenance records |
Force Preventive Maintenance Plans
Force offers two PM plans designed for construction equipment operating on job sites:
Basic Plan — Monthly per machine
- •Scheduled service every 250 hours
- •Engine oil and filter changes
- •All fluid level checks and top-offs
- •Air filter inspection and replacement
- •Visual inspection with written condition report
- •Priority scheduling for any needed repairs
- •Maintenance records maintained and accessible
Complete Plan — Monthly per machine
Everything in Basic, plus:
- •Hydraulic fluid sampling and lab analysis every 500 hours
- •Fuel system inspection including injector health
- •Coolant testing and flush on schedule
- •Full electrical system diagnostics every 1,000 hours
- •Undercarriage measurement and wear tracking (tracked machines)
- •Dealer-grade diagnostic scan every 500 hours
- •24-hour emergency repair response guarantee
- •Annual comprehensive machine inspection with written report
What Each Plan Prevents
The Basic plan catches the obvious failures — the ones that come from neglected oil changes, clogged filters, and low fluid levels. These account for roughly 40% of unplanned breakdowns.
The Complete plan adds predictive diagnostics — hydraulic fluid analysis detects metal particles from wearing components before they fail. Electrical diagnostics catch voltage issues before they leave a machine dead. Injector health monitoring prevents the power loss and fuel waste that comes from degraded fuel delivery. This catches an additional 35-40% of potential failures.
ROI Calculation
For a single machine valued at $250,000 operating 1,500 hours/year:
- •Without PM — Average 3-4 unplanned breakdowns/year. Cost: $24,000-$48,000 in repairs and downtime.
- •Basic PM — Reduces unplanned breakdowns by 40%. Annual PM cost: contact for pricing. Avoided cost: $9,600-$19,200. Net savings: $4,200-$13,800.
- •Complete PM — Reduces unplanned breakdowns by 75-80%. Annual PM cost: contact for pricing. Avoided cost: $18,000-$38,400. Net savings: $7,800-$28,200.
The Complete plan pays for itself if it prevents just one major breakdown per year.
How to Get Started
Contact Force for a fleet assessment. We'll review your equipment list, current maintenance records, and operating conditions, then recommend the right plan for each machine. Service starts within one week of agreement.
All service is performed on-site by Force technicians using dealer-grade diagnostic equipment. No need to transport machines to a shop for routine maintenance.
