See Pic. 33.
– Screwdriver ground to shape for piston pin circlip removal
(see Pic. 33)
– compression tracer and 2 pressure gauges, adapter for dial
gauge in spark plug thread
– valve spring pliers
– step punch for valve guide
– adjustable reamer 6,5 ÷ 7,5 mm
– valve seat rework set, valve lapping paste
– gearbox support plate
– stud extraction tool
– scraper, lapping fleece, grinding tool, cover sheet, adhesive tape
– cleaning agent, approved cleaners, funnel, graphite marker.
– magnetic particle tester DEUTROFLUX, series UHW, or adequate. These testers
are suitable for complete combined magnetic particle crack inspection of all
ferromagnetic materials. For this purpose an A.C. field circulation can be combined
with a shifted phase A.C. circulation . Both magnetizing methods are independent
from each other and can be applied separately.
To achieve the direction changes of the magnetic field vector necessary for
indication of cracks in any direction, the alternating current serving as current
supply for the different methods of magnetizing are dephased by 120° to each
other:
a) current circulation for longitudinal cracks
b) field circulation for transverse cracks
c) auxiliary circulation for axial and radial crack indication on parts with through
by using an electric auxiliary conductor (copper bar).
