Subject: Rebuilding of reels for proper rolling resistance.
Incorrect installation of the reel seals may result in higher than expected reel drive
forces which can affect the life of the reel drive clutch. The Reel Shaft Seal Installation
procedure included with this bulletin may be helpful in performing a successful repair.
Use this information as a supplement to the information found in the Service Manual.
Before operating a rebuilt cutting unit, the rolling resistance of the reel should be
checked (no bedknife contact). The rolling resistance of the reel alone is approximately
15 in-lb (1.7 Nm). The addition of a Groomer will increase rolling resistance by about 6
in-lb (0.7 Nm). In other words, a new or rebuilt cutting unit with a Groomer installed
should be about 21 in-lb (2.4 Nm). If the rolling resistance exceeds the specified value,
the condition should be corrected.
Note:
Be sure to inspect for proper mow and traction cable tension as identified in the
Operator’s Manual. Also, be aware that a traction cable set at the maximum
tension will reduce the amount of tension available for the mow cable. Do not
exceed maximum cable tension values.
Consider an Upgrade:
An alternative to this instruction would be to convert the seal package to the current V-
ring seal configuration, which has a lower rolling resistance and is easier to install.
Contact your local Commercial Products Distributor if you have any questions about
converting or the following Seal Installation information in this bulletin.
