This month we look at a Hino EM100 engine being reconditioned. This particular engine had a very large external crack running
between welch plugs. The crack repair process utilised state of the art Cast Master repair plugs. The cost of the crack repair was around $800.00, the cost of a new Hino block was approximately 10 times more.
The Hino block is dismantled and prepared for a chemical clean.

All paint, rust, oil and carbon deposits have been removed.
With the block now adequately cleaned the crack can now be seen by the naked eye. A formal crack test using Ultra Violet light establishes the limits of the crack. Click here to see the cracked
