## Overview

A mining contractor operating wheel loaders and haul trucks in a cold, high-altitude environment needed replacement engines and a winter-ready parts stock to keep the fleet productive through the season.

## Challenge

Cold starting, dust, and long haul cycles shorten engine life. The contractor wanted engines with cold-start packages and a parts stock sized for a full winter, delivered overland before the roads closed.

## Solution

| Item | Model | Qty |
| --- | --- | --- |
| Wheel loader diesel engine | Weichai WD615G.240 | 6 |
| Truck / machinery diesel engine | Yuchai YC6J220-30, 162 kW | 4 |
| Construction machinery engine | Yuchai YC6A190L-T20, 140 kW | 3 |
| Cold-start and dust packages | Block heaters, heavy-duty air-filter assemblies, batteries and cables | 13 sets |
| Winter parts stock | Filters, belts, glow plugs, injectors, water pumps | 1 lot |

## Scope of supply

Engine selection from machine data, cold-climate accessory packages, overland truck export from Shanghai via Erenhot, DAP mine site, and a workshop maintenance manual set.

## Outcome

All engines were installed before winter and the fleet completed the season without engine-related stoppages. The contractor has set up an annual pre-winter parts order with MARS.
