Ford 1710

This post is about a small metal stitching repair that we carried out on the cylinder head of a Ford 1710 tractor built in 1984.

The cylinder head of this 3-cylinder, 1’400 cc (85 cu in), 84 mm bore and 84 mm stroke engine suffered from a crack close to one of the fuel injectors. The crack led to cooling water leaking into the combustion chamber. The cylinder head had been repaired before, by metal stitching, but not by us.

To permanently repair it, we carried out the following work on the cylinder head of this 19.4 kW (26 hp) engine:

  • Dismantling
  • Visual and Magnetic Particle Inspection (MPI)
  • Metal stitching of two cracks
  • Milling of the landing surface
  • Reassembly
  • Pressure testing

Metal stitching cracks inside various engines’ combustion chambers is something that we routinely do with excellent results. Our repairs are well able to withstand the challenging environment of up to 200 bars (2’900 psi) pressure and 350° C temperature that exists there. This time, the repair will last (unlike the earlier one, not done by us).

  1. What’s the price for a repair like this? I have a head that is cracked in same area. Off a ford h843 engine.
