Procedure for 1st assembly

lubricating oil bores and lubricating ducts must be kept absolutely

clean to protect the ball bearings ! This applies to the lubricating oil

1) Provide the housing Pos. 008 after pinning with parallel pins Pos. 055.

2) Fit the housing Pos. 008 and measure dimension "a" in accordance withdetail N. Then remove the housing again.

3) Finish-machine adjusting disc Pos. 009 to dimension " x ".

4) Fit the elastic screw Pos. 003 in the lever of the connecting unit Pos. 004. see section A-A and detail L


5) Mount connecting unit Pos. 004 on drive shaft. see sections A-A and C-C

1) Insert shaft encoder Pos. 003 in guide of bearing housing Pos. 002, and fitwith inner bolts, washers, and locking plates (Pos. 014, 026, 029)

2) Push shaft encoder Pos. 003 inwards.

Important: The holder of the shaft encoder should be easily movable inthe guide !

3 Place toothed belt Pos. 005 and brin the mark of ear wheel Pos. 004 to

position "TDC 1" (vertically pointing to the top). Important: locating pin inbearing housing opposite (vertical to the bottom), see view B.

4) Align the horizontal marks on gear wheel and holder of shaft encoder Pos.

003 with each other.

5) Push shaft encoder Pos. 003 outwards till toothed belt is slightly tensioned.
