  Home » Horton Fan Drive Core Exchange Program
  The following guidelines are designed to help customers accurately identify and inspect all models of the Horton fan drives offered for acceptance in the Horton Core Exchange Program.

Horton fan drive cores are divided into (3) three categories for exchange credit.
Full Credit
  • Fan Drive is identified in the Horton Reman Program and meets all the guidelines.
Partial Credit
  • Fan Drive is identified in the Horton Reman Program, but has one damaged main casting or cannot turn.
Zero Credit
  • Fan Drive is not in the Horton Reman Program or
  • Fan drive is identified in the Horton Reman Program, but has more than one damaged main casting or
  • Fan drive is identified in the Horton Reman Program, has one damaged main casting and doesn’t turn.
  HORTON FAN DRIVE CORE EXCHANGE GUIDELINES
  1. The core must match one of the fan drives offered in the reman program. Refer to the Core Identification Section in the Horton Remanufactured Fan Drives catalog (#22213) or the New to Reman Fan Drive Cross Reference Table (#22792).
    2.

  2. The core must be complete. The core must include a bracket, a sheave, a piston friction disc (PFD) and an air chamber as shown in the exchange core identification section below. The core is acceptable with or without fan mounting studs of any length and if the studs are bent or broken.
    3.

  3. Main castings such as mounting brackets, sheaves, friction discs, and air chambers must not be visibly cracked, broken, galled, or welded.
  

  1. The sheave and PFD/air chamber must turn; they must not be frozen to the mounting bracket shaft. To check to see if they will turn, hold the mounting bracket with one hand and turn the sheave and PFD/air chamber with the other hand. You must be able to turn the sheave and PFD/air chamber independently of the mounting bracket. No mechanical devices can be used. The rotation of these parts must
    occur with the core at room temperature. The sheave and PFD/air chamber can turn
    independently of one another or together at the same time.

    2.

  2. The core must not be damaged by
    non-operational causes such as rust or rough handling. If a core is damaged
    during shipment, the core will be
    considered for partial or zero credit as
    defined above.     For this reason, the
    return packaging must protect the core from
    damage while shipping.

HORTON MSC-3 FAN DRIVE CORE EXCHANGE PROGRAM
  The following guidelines are designed to help customers accurately identify and inspect MSC-3  Horton fan drives offered for acceptance in the Horton Core Exchange Program.

Horton fan drive cores are divided into (3) three categories for exchange credit.
Full Credit
  • Fan Drive can have up to 1 damaged main casting.
Partial Credit
  • Fan Drive has 2 to 3 damaged main castings, or
  • Fan drive cannot turn PFD/air chamber/adaptor independently of bracket (seized hub bearing), or

  • Fan drive cannot turn sheave/cooling ring independently of PFD/air chamber/adaptor (seized sheave bearing).
Zero Credit
  • Fan Drive has 4 or more damaged main castings, or

  • Fan drive cannot turn sheave/cooling ring independently of bracket (seized sheave and hub bearing).
  HORTON FAN DRIVE CORE EXCHANGE GUIDELINES

  1. The core must match one of the fan drives offered in the MSC-3 core exchange program (798001, 798002, 988000, 998000, 988001, 998001, 988002, 998002).

    2.

  2. The core must be complete. The core must include a bracket, sheave, piston friction disc (PFD), air chamber, cooling ring, and adaptor.
  3. Main castings such as mounting brackets, sheaves, friction discs, and air chambers must not be visibly cracked, broken, galled, or welded.
  

  1. To receive full credit, the internal bearings must rotate freely. To check to see if they will turn, hold the mounting bracket in place and rotate both the sheave/cooling ring and PFD/air chamber/adaptor. You must be able to turn the sheave/cooling ring and PFD/air chamber/adaptor independently of each other, and also the mounting bracket. No mechanical devices can be used. The rotation of these parts must occur with the core at room temperature.

    2.

  2. The core must not be damaged by
    non-operational causes such as rust or rough handling. If a core is damaged
    during shipment, the core will be
    considered for partial or zero credit as
    defined above.     For this reason, the
    return packaging must protect the core from
    damage while shipping.
