Here at JASPER, numerous machining processes are performed during engine remanufacturing. In our block and head machining areas, cuttings from milling and boring get into the castings, and we use multiple steps to clean these castings and ensure the cleanliness of the engine.

After the final machining process, castings are placed in high-flow rotary spray cabinets. These cabinets flow at 200 gallons a minute to thoroughly flood those castings and flush out the bulk of that remaining debris. The cleaning chemistry is filtered through 25 micron bag filters for gross removal of this contamination.

From there, the castings are moved into a final wash station. Here, all the oil galleries and bores are brushed to dislodge any remaining chips and shavings. Final tanks an agi-lift style tank which continuously submerges the casting and then elevates it above the aqueous cleaning bath. The ebb and flow of the water through the casting draws out any of the remaining debris.

As this is the final cleaning step, these tanks are filtered to 10 micron as well as having magnetic particle filtration. The tanks are electronically monitored for flow to ensure a constant tank turnover rate of four times per hour. If flow drops below the threshold, the monitoring system shuts the tank down until the filtration problem has been addressed.

Focusing on the cleanliness of the post machining castings is just one of the ways JASPER works to produce the perfect product.
