During adjustment, check cap nut and counternut for tight seat and wear. 05.8-210\/1 F2 63 Cap nut 63a Counternut &nbsp; &nbsp; &nbsp; Also check valves which are not in need of adjustment. Renew cap nuts and counternuts in the following cases: &nbsp; Height of counternut (A) below 5 mm (H). New counternuts (B) have a height of 6 mm. &nbsp; Counterlocking surfaces of nuts badly worn (arrows). In such cases, check threads on valve stem and also replace valves, if required. &nbsp; Check camshafts made of malleable iron (code number 00) for wear. Formation of excessive flats on cam (arrow) may result in loosening of counterlocked nuts. If flats show up, renew camshaft, rocker arm, valve springs, as well as cap nuts and counternuts. Also check valves and replace, if required. 105-14501 &nbsp; 05.8-210\/2 F2 &nbsp; &nbsp; &nbsp; On camshafts made of chilled cast iron (code number 05 and 08) a slight formation of flats is possible, but flats will not increase and are therefore technically insignificant. &nbsp; Adjustment 1 Disconnect regulating linkage to remove cylinder head cover. Pull out locking eye of longitudinal regu\u00adlating shaft (arrow). Model 126.120 &nbsp; On models 116.120 and 123, pull longitudinal regu\u00adlating shaft out of rubber mount in forward direction and remove in rearward direction. Model 123 &nbsp; On models 123 with automatic transmission 722.303 (W 4 A 040) and 126.120, pull off central plug for vacuum lines (71) or vacuum lines.

Tip of cam should be vertical in relation to rocker arm. Valve clearance is correctly set when pulling of slip gage blade requires some effort. &nbsp; Observe layout of intake and exhaust valves.
