One of our new service areas is honing of cylinder liners.
Honing becomes necessary, when rings and liners are suffering from wear and missing honing pattern.
With our Gehringer honing machine, cylinder liners with a diameter of 150 mm up to 450 mm can be machined.
Gehringer honing machine specification
Stroke. : 1500 mm
Bore.... : 0 - 450 mm
Upon receipt each cylinder liner is cleaned and the inside diameter measured.
We carry out control of all o-ring grooves, check of landing surface and sealing surface.
The liners are then honed to re-establish liner geometry of the entire running surface and thereafter final check measurements is taken together with roughness measurement (Ra)
A report of the work performed will be provided upon completion.
If the initial control of the cylinder liner indicates that reconditioning is not possible, the liner is rejected, and the customer will be informed, and new liners will subsequently be quoted.
All liners packed in wooden boxes (not included in list prices) in accordance with ISPM 15 standard for world-wide transport.
Honing of liners for four stroke engines is carried out in our workshop facilities in Rodby.
