Hydraulic Lash Adjuster Purpose of Lash Adjuster

Different Polishers Engis Corporation Manufacter Diamond and CBN (Cubic Boron Nitride) electoplated and impregnated mandrils Highly expensive due to custom order

Polishing Tests Engineers at GT didn’t seem to think material change improve polish Super-abrasives might still last longer than ruby However, the group was encouraged to continue with the polishing test and provide the results to GT.

Polishing Test… The tests will be performed with the fine grit ruby stone. Our contact at GT, Dan Faulkner will setup the polishers for the experiment. Due to the amount of business that GT incurs, polishing tests have not yet been done.

Imaging Contacted Dr. Liang at the FAMU-FSU COE IE Minolta imaging machine was capable but out of service. Samples will be sent to Dymek for analysis

Improved Holder Currently there three different stone lengths. Long stones extend well past the holder end causing the polishing stone to be less stable We will design an adjustable holder for various stone lengths.

Preliminary Design Metal Sleeve to extend support Locking nut to secure the location of the support

Lubrication Theory Capillary seal involves flow around two concentric cylinders Spherical bearing measures the thin flow around a spherical check valve
