Complete Engine Assembly

We provide full-service engine assembly from the block up, ensuring each component is measured, cleaned, fitted, and torqued to exact specifications. Perfect for full rebuilds, restorations, or performance engine projects.

Piston & Rod Installation

Our machinists install pistons and connecting rods with precise clearances, ensuring smooth operation, reduced friction, and long-term reliability.

Piston Ring Fitting & Gap Adjustment

Proper ring gap is essential for compression, oil control, and engine performance. We measure, file-fit, and install rings to achieve optimal sealing and maximum efficiency.

Wrist Pin Fitting & Balancing

We inspect and fit wrist pins to ensure perfect alignment and smooth motion. This step helps reduce vibration and improves engine durability.

Bearing Installation & Measurement

We measure and install main and rod bearings to achieve ideal oil clearance. This critical process prevents premature wear and improves lubrication at all RPM ranges.

Torque, Clearance & Spec Verification

Every fastener, clearance, and tolerance is checked during assembly, guaranteeing the engine meets or exceeds manufacturer standards.

Pre-Lubrication & Break-In Preparation

We prepare your newly assembled engine for first start-up with proper lubrication, ensuring safe break-in and optimal performance from day one.
