Inspection

The use of an endoscope enables both valves (plus

cylinder wall) to be inspected without removing the

head.

The endoscope with transformer for 110/220

volts a.c., as well as the valve pliers, can be

obtained from the Deutz head office.

Job:

Refitting

Remove rocker arm cover. Turn crankshaft until the

relevant piston is in TDC position and the valves to

be inspected are fully open. Remove injector (job

07.07.01) and clean injector bore in cylinder head (3).

Connect endoscope (2) to transformer (1). Lower

endoscope (with weak light) into the injector bore

until valve tulips and valve seats are visible.

Use endoscope, if possible, with max. 11 volts

and no longer than necessary, owing to the

high heat development. Never touch lamp nor

distort or strike endoscope.

Handle carefully !
