Additional services include cylinder overhaul, boroscope inspection and connecting
rod bush boring.

CYLINDER OVERHAUL: During overhaul all aspects of your cylinder are taken into
account. Your cylinder is thoroughly inspected for cracks, visual defects and
dimensional conformance. If necessary and dimensions permitting your cylinder
will be re bored to oversize and honed. Other cylinder repairs carried out at our
facility include spot facing, valve guide replacement, valve seat cutting, valve face
grinding, honing and stud replacement.

BOROSCOPE: Boroscope inspection can be carried out locally on your engine to
assess the condition of your cylinders internally without having to remove them.

CONNECTING ROD BUSH BORING: After fitment of new bushes to your
connecting rods, these bushes are precisely machined on our boring machine to
the exact size required.
