Caterpillar 3512 — Overhaul Considerations
Testing & diagnosis · Engine
For the Caterpillar 3512, from the Caterpillar owner's manual.
Applies to: Caterpillar 3512
Procedure
- Use total fuel consumption as the most important factor for estimating the overhaul interval.
- Estimate the hours until overhaul using the equation H = F/R.
- If actual fuel consumption records are not available, estimate the average percent of load and use the engine spec sheet.
- Monitor oil consumption; when it has risen to three times the original rate, schedule an engine overhaul.
- Monitor noise, vibration, oil consumption, and crankcase blowby.
- Consult your Caterpillar dealer about scheduling a major overhaul.
Specs & values
- H = F/R, where H is estimated hours until overhaul, F is estimated total fuel consumption, and R is the rate of fuel consumption in liters per hour or gallons per hour
- Schedule overhaul when oil consumption has risen to three times the original rate
