The ATC 40127 Input Shaft Bearing Puller is the specialized tool for safe, damage-free removal of input shaft bearings on Eaton Fuller UltraShift Plus automated transmissions (shaft #4308011)—prevents shaft scoring, race damage, gear tooth harm, and costly collateral issues during bearing service or overhaul. The High Costs of Improper Input Shaft Bearing Removal on UltraShift Plus Using generic pullers, pry bars, or heat on input shaft bearings often scores the shaft, damages races, chips gear teeth, or destroys adjacent components—leading to leaks, misalignment, or complete transmission teardown. Input shaft scoring / damage – $1,200–$4,000 shaft replacement Bearing race or gear tooth harm – $800–$3,500 parts & labor Collateral internal damage – $2,000–$8,000+ partial/full rebuild Transmission contamination / failure – $5,000–$15,000 complete overhaul Truck downtime – 4–15 days ($800–$2,500/day fleet loss) Rework labor overrun — Extra 20–60 hours at $150–$350/hr What is the ATC 40127 Input Shaft Bearing Puller?
