What is a Pocket?
Top of Page
  • On site line boring can take place on large numbers of in-line bores e.g. main journal pockets. These can be accurately machined and aligned with several metres separating each bore.
  • We cater for diameters ranging from 25mm to 1000mm as standard, with individual bore lengths up to 3 metres.
  • Optical and Laser Alignment is used to ensure total accuracy.
  • Our in-situ electroplating and line boring service can restore your pockets and caps to original size and tolerance.

 Liner Landing Machining & Repairs

  • Both upper and lower Liner Landings can be machined to remove damage to the face and to the bore.
  • Inserts of cast iron or steel can be supplied and fitted to return the bores to original size and specification.
  •  New!
    Top liner lands (on SEMT Pielstick engines in particular) can be machined without removing the studs using our specially designed machine.

What is a Cylinder Head?
Top of Page
  • Most of this work is carried out in our workshops and not In-Situ.
  • We can fusion weld your cracked Cylinder Head and refit and refurbish the valve guides as required. We can re-machine the Cylinder Head (to correct any distortion) which is then cleaned and painted as required.
  • We can also carry out a Metal Stitch repair to some parts of the Cylinder Head if applicable.
 
 Cylinder Liners
  • We carry out Cyliner De-Glazing and Honing of Cylinder Liners both at our Glasgow factory and In-situ.
  • A perfect cross hatch finish is produced and ovality can be removed by our process unlike many other so called de-glazing processes.
  • We can also refurbish the seal areas on old liners by chrome plating or Metal Spraying and grinding.
