Diesel Head & Parts started fusion welding more than twenty years ago. Fusion
welding is the process of removing the cracked and damaged areas from cylinder heads and
then using modern casting technologies to return those areas to OEM quality. The
cylinder heads are reassembled using new parts and then tested for integrity. All of
our work meets or exceeds OEM specifications at a cost significantly lower than purchasing
new components.
The process below shows the typical steps taken in remanufacturing of cylinder
heads. If you have any questions at all go to the bottom of the page, fill in the
form and we will get back to you as soon as possible.

Cylinder heads come into our warehouse where
they are inspected and disassembled. The next step is for the parts to be cleaned in
our high efficiency cleaning oven. This process burns away grease and carbon
deposits and is more environmental friendly than acid cleaning. |
 |
To finish the cleaning process the cylinder
heads are then placed into a steel shot machine. This process removes any residual
rust, dirt and grim. As you can see cylinder heads come out bright and shiny. |
 |
To ensure there is no residual shot cylinder
heads are then placed in a tumbler to remove any steel particles that may remain.
This process also removes rust particles, machine cuttings and any other foreign debris. |
 |
Cylinder heads that are cracked, pitted or
damaged in other way that machining cannot fix then it is on to fusion welding and
re-casting. |
 |
After cylinder heads have been fusion welded
the next step is our machining process. |
 |
After machining, cylinder heads are moved to
our production line for internal parts installation. |
 |
After internal parts installation valve seats
and injector holes are machined ensuring concentricity and injector alignment. |
 |
To ensure that cylinder head is level it is
then re-surfaced. This process meets RMS. standards while providing a good mating
surface and positive seal. |
