Cylinder Heads

We carry out cylinder head rework on site & this includes but is not exhaustive to pressure testing, re-surfacing, valves supplied & fitted, guides replaced & valve seats cut & replaced.

We have all makes of reconditioned cylinder heads on the shelf. All sold on an exchange basis with a surcharge – returnable upon receipt of the complete old unit.

Below is an example of the work carried out on our reconditioned heads

 

Cylinder Head – Reconditioned

• Every cylinder head is inspected for cracks
• Engines with OHC configurations have the camshaft bores measured for size, ovality, taper and alignment and are either restored to OEM specification or scrapped
• Valve guides are measured for wear and either resized or renewed to conform to original tolerances
• Valve seats are machined to retain the correct seat angles, widths, valve heights and valve seating concentric with the centre line of the valve guide bore
• Valves are examined for damage, head thickness and stem wear and replaced or machined as necessary
• All valve springs are tested for squareness, free height and compressed load length
• Cylinder heads are checked for distortion and thickness
• When machining the cylinder head face, attention is paid to maintaining the surface finish specified by the gasket manufacturer.
