  2. OPERATION MISTAKE PROOFING Operation : Bearing cap drilling

  3. Scope:- Detection for oil hole crossed thoroughly Operation:-Oil hole gallery drilling Machine No:-RDM 578/548/552

  4. Coolant was passed through the oil hole. Passed coolant was flowing through all Crossed oil holes as shown in the picture. Oil hole Ø4 mm is opened in cam bore Ø52mm & crosses to the coolant input hole Ø11mm. This hole was shifted & could not detected by this method. Previous method of detection

  5. New gauge is produced to check the Ø4 mm oil hole crossed in correct position. Gauge is having hole & hole distance is controlled from face as per drg. If oil hole is throughlycrossed in Ø52 bore coolant is passes through the gauge hole & flows at gauge end portion as shown in the picture. Present method of detection Coolant is Passing after Matching gauge Hole to job hole

  6. Operation :- Dip stick hole drilling. SCOPE:-POKAYOKE FOR DIPSTICK HOLE • Drilling & Reaming of Hole Ø11 +0.018 is carried out on RDM. • Coolant is passed through oil hole by nozzle pin having Ø11 -0.05. • If reaming opn. Is missed nozzle pin will not enter in the bore.

  7. Operation :Bearing cap notching SCOPE:-MISTAKE PROOFING • Previous : • Job was located on two location pins. So there was • possibility of wrong fitment • Of bearing cap on pins.

  8. Rest pad added MISTAKE PROOFING After : • Added one rest pad on fixture. So that wrong position bearing cap could not fit on location pins.

  9. LOADING / UNLOADING TIME REDUCTION Operation : Bearing cap drilling

  10. Previous : Bearing cap was mounted on jig with the help of two individual stud. Time for clamping two stud is mins per job.

  11. After : C clamp is introduced to hold the brg. Cap as shown in the picture no.1. So only one center clamp is require to lock only instead of two individual stud. Time for clamping ‘C’ clamp is mins per job.

  12. III rd operation Operation : Tappet Boring Machine No. ; 2830 • Previous operation is bearing cap assembly. • Proxy is fitted near roller below job resting face at gear end face . • If bearing is fitted at wrong side i.e. Fw End side instead of gear end side gap between proxy & cap face will increase & machine will not start.
