This brake housing would normally be scrapped the moment gear teeth start cracking. The client did not have that option.
Within eight weeks, HVT secured engineering and quality approval for the repair and returned a working housing for the next major service. More than 30% of the cast iron gear teeth were repaired, all bores and the PCD were kept in alignment and backlash was proven at no more than 0.075 mm. The unit had to be qualified for a minimum 5,000-hour service interval.
HVT started with a controlled proof segment. A small section of teeth were repaired and then independently checked through a local NATA-certified lab. Material analysis and NDT were used to confirm the repair quality and integrity before scaling up.
Once approved, the housing repair became a repeatable process. Each tooth was repaired to completion before moving on, controlling heat input and sequence to protect every critical alignment. After welding, the repaired teeth were hand scraped and fitted, then tested for engagement and backlash.
The finished housing surprised even the client.
This project was a test of heat control, tooth geometry and verification under strict acceptance criteria. It proved that a validated cast iron tooth refurbished, executed tooth-by-tooth, can meet and even outperform replacement performance when supply and downtime make new parts unrealistic.
