1997/10/27 Caterpillar

Stronger Sun Visor Guides Available {7300,7340}

Usage:

Challenger 35 (8DN),
Challenger 45 (1DR),
Challenger 55 (7DM) Agricultural Tractors

Description of Change: A stronger sun visor guide is now available. The parts service only sun visor guide is constructed of a solid rod rather than a formed tube.

NOTE: The same part number is used for both left and right sides. As a result, it is no longer necessary to purchase the entire sun visor mounting kit if only a single guide is broken.

Adaptable To: The 145-4702 Sun Visor Guide may be used if an existing guide is broken. The formed-tube guide design remains in production and in the 117-7000 Sun Visor Mounting Kit. The new guide is currently only available through Morton Parts.

NOTE: The new guide cannot be paired with the formed tube design. As a result, if one formed tube guide is broken, then two new 145-4702 Sun Visor Guides should be ordered as replacements.
