HARDI MEGA 230 / 350 CENTRIFUGAL OPERATORS MANUAL
8.2 Checking and Adjusting Sprocket Timing
1. With boom unfolded in the working position, check to ensure that the
seventh pin connection (A) in the timing chain is aligned with the
center line between the sprocket cap screws (B).
2. To adjust timing, loosen turnbuckles on the front and rear cables until
slack.
3. Standing on the front side of the boom, position the seventh pin (A) of
the timing chain on the sprocket as indicated in step 1.
4. Adjust front and rear cable tension. (Refer to sections 8.5 & 8.10)
8.3 Aligning Wing Assemblies
(Fig. 37)
1. With boom unfolded and in the working position, check alignment of
the intermediate section with the center frame.
2. With fold cylinder pressurized, determine if the intermediate section
needs to be adjusted to the front or rear to come into alignment with
center frame.
NOTE: Because of adjustments made later, it is better to start with the
wing assemblies angled slightly to the rear.
3. Relieve pressure from cylinder by folding boom in a few inches.
NOTE: Cylinder rods have a machined flat which, if visible, can be used
for adjustments. If using machined flat for adjustment, leave rod
eye pinned to boom and loosen jam nut
