Problem:
Original trigger lever was metal to metal contact on regulator block, causing prema-ture wear.
Original trigger lever pot would wear and allow lever to lean, eventually allowing lever to fall behind ramp. Original lever bird beak bearing would rust and fail.
Solution:
Pennsy’s TMB Trigger Lever
A large boss was added to pivot to prevent premature wear and keep lever in proper orientation.
A polymer roller replaces steel bearing, preventing corrosion and ramp wear.
A polymer cap prevents wear on ramp and guide.
Results:
- Polymer roller eliminates rusted failed roller bearing, and also prevents ramp wear
- Large pivot boss maintains lever position for accurate slack adjuster setting for empty or loaded railcar and prevents lever locating behind regulator block
- Cap prevents regulator block wear
- Increases component life of empty/load system, reducing railcar maintenance and shop time
