Pre/post lubrication pump for trucks

The pre/post lubrication pump improves lubrication of the parts and increases the service life of the engine.

Description

Sandvik introduces a new pre/post lubrication pump option for TH551i and TH663i dump trucks. The pre/post lubrication pump improves lubrication of the parts and increases the service life of the engine.

The pre/post lubrication pump operates in two ways, namely:

1. Pre-lubrication:
Before engine start, the pump delivers engine oil to engine components such as bearings and turbocharger, and raises engine oil pressure. Pre-lubrication reduces cold start bearing wear and prevents engine startup, until engine oil pressure is achieved.

2. Post-lubrication:
After engine shut down, the pump delivers engine oil through the turbocharger to cool down the switched off turbocharger. Post-lubrication will activate when:
•Hot engine has been shut down
•Turbo timer has not activated
•Turbo timer has been interrupted
•Engine shuts down suddenly, for example, when coolant level is low and continue oil circulation for 5 minutes after engine shut down.
Advantages

-Ensures proper lubrication before start and after shutdown.
-Reduces cold‑start wear and protects engine and turbocharger.
-Extends component and engine service life.
Customer values

-Increased reliability and reduced risk of unexpected failures.
-Lower maintenance costs thanks to longer engine and turbo life.
-Improved uptime and overall equipment availability.
