How to Make an Interchange
Example 1: Your customer wants to replace a Dodge TXT 425 with a taper bushed design. However, the available driven shaft length (2 7/16” diameter) is only 6 1/2”. Select a Falk Quadrive replacement drive.
Step 1 — From Page 7, Table 1, a Size 5207J with a 25:1 nominal ratio is the correct interchange for a Dodge Size 4.
Step 2 — For a Size 5207JR shaft mounted drive a 2 7/16” TA
Taper bushing requires a minimum 6.11 inch driven shaft length. Your customer will require a new sheave or sheave bushing (1.5” diameter vs. 1.437” diameter high speed shaft) and may need to adjust the motor and tie rod position.
