DG-800B, DG-808C, DG-500MB Adjustment of propeller after jump of drive belt
Issued: 14. May 2010

approx.
20 mm
(0.79 in.)
If during engine retraction the
propeller can’t be stopped in the
vertical position, the relation between
propeller and motor must be checked.
With the propeller vertical, there
should be an approx. 20mm distance
(as in the picture to the right).

800B, DG-808C and DG-500MB
section 1.11.4
If the drive belt jumped, the problem may be easily corrected with an approx. 30mm wide by
100mm long piece of Mylar tape.
If the distance is less than 20mm, for instance 0mm, the piece of Mylar tape must be inserted
as shown in the photo below and run between the bottom pulley and drive belt by turning the
propeller. The propeller must be turned until the tape fully emerges from the other side.
If the distance is much larger than 20mm, the piece of Mylar tape should be placed on the
other side.
Repeat the procedure as necessary until the correct distance is reached.
