Concentric Power: Why the ATC RR1012TR Kit is the Eaton Roadranger Master Standard
Setting countershaft bearings on an Eaton Roadranger transmission leaves zero margin for error. The ATC RR1012TR Master Kit provides the precision-ground engineering needed to drive and pull bearings without fracturing case walls or marring shafts.
The High Stakes of Heavy Duty Transmission Overhauls
In the world of heavy truck drivetrains, the Eaton Fuller Roadranger series stands as a monument to durability. However, during a complete bench overhaul or in-frame gear train service, managing the countershaft bearings presents a severe mechanical bottleneck. Countershaft bearings must be seated perfectly square within the aluminum or iron main case bores. Attempting to install or extract these tight-clearance components using generic brass drifts, sleeve pipes, or flat drivers is a recipe for a costly teardown. An uneven blow can cock the bearing race, scoring the case bore permanently, damaging the gear teeth alignment, or micro-fracturing the bearing cage. The ATC RR1012TR kit provides an all-inclusive master system featuring application-specific drivers and pullers that distribute force 360-degrees evenly along the centerline axis.
- Comprehensive 5-Piece Arsenal – Fully loaded with the RR1012TR-2 Front Driver, RR1012TR-3 Rear Puller, RR1012TR-4 Rear Driver, RR1012TR-5 Auxiliary Puller, and the RR1012TR-6 Auxiliary Driver.
- Flawless Force Distribution – Specialized step-driver profiles target only the bearing races to prevent impact shock from shattering fragile needle cages or ball tracks.
- Uncompromising Mechanical Extraction – Dedicated auxiliary and rear puller units clamp tightly behind tight-seated gears, sliding bearings out smoothly without gouging shafts.
- True Main Case Protection – Eliminates cocked entries, ensuring the transmission case bores remain concentric to preserve optimal shaft gear backlash.
- Heavy Iron Shop Armor – A massive, professional-grade shop master package weighing in at a substantial 33.00 lbs to withstand continuous high-impact pneumatic or manual weapon force.
