Replacement engines

Overhauled replacement engine for gasoline driven Smart 

The engines are revised by passing through several work stations which are subdivided into process steps. - Polishing of cylinder head, grinding-in of specially hardened valves.
- Crankshaft polishing and rebalancing.
- Drilling, honing and face milling of the engine block.
- Renewing of pistons and piston rings.
- Installation of a revised oil pan.

Manual precision work and many years of experience ensure the long endurance of your engine.

Revised oil pan

To assure complete drain of used engine oil for the future we install an oil drain plug at the lowest point of the oil pan.
