Home › Knowledge Base › Field Case: A CAT Dozer Down on Site — Spares Planned in Advance Cut Downtime to Two Days
Case in one line: Before his old CAT dozer's major service, the customer pre-quoted the cooling trio (water pump, thermostat, belt) matched to his serial. Three months later it happened: temperature pegged, pump shaft seal leaking. The numbers were already in our system — one call shipped same day, back to work in two days. That's what a spares plan is worth: thousands a day.

How it went

WhenWhat happened
3 months earlierCustomer quoted our "old-fleet service spares list": water pump + thermostat + belt, matched by serial (not ordered yet)
Breakdown dayTemperature pegged, work stopped. Customer sent a screenshot of the old quote: "This set — ship the pump first"
Same dayStock confirmed from our records, shipped, tracking number back within the hour
Two days laterPump fitted, thermostat swapped at the same time (it was on the list too), work resumed

The play: stock high-failure parts before major service

SystemStock theseWhy
CoolingWater pump, thermostat, beltsThe most common breakdown; small parts, huge downtime cost
HydraulicsPilot filter, common seal kitsMost "erratic action" starts here
Electrical1-2 common sensorsFalse-alarm stoppages are usually sensors
ConsumablesAir & oil filter setService without waiting on parts

Send us the model and serial and we'll produce a free high-failure spares list for your build range — one inquiry that covers a whole service cycle.

Appendix: 4 ways to get the exact part right the first time

MethodWhat you provideResult
1. Part number (fastest)The part number / VOE number / CAT number — nothing else neededStock and price confirmed within minutes; 100% precise
2. Model + serial number + yeare.g. EC210B + machine serial + year 2015The same model can have several versions — the serial number pins it down
3. Photo of nameplate / old partA clear photo of the machine nameplate, or the printed/stamped number on the old partWe verify fitment from the photo — our responsibility, not yours
4. Fault description + replacement historyBriefly describe the symptom and whether/when this part was replaced beforeWe help judge what to replace — and whether a root cause is still hiding

Send any one of the four to our online chat to lock in the right part. The more you share, the faster and more accurate the quote.
