Bonbo Input Shaft Bearing Puller Kit for Eaton Fuller 1 3/4" & 2" Shafts — Hardened Steel, Controlled Extraction

This professional-grade puller set is engineered specifically to fit Eaton Fuller transmissions with 1 3/4" and 2" input shafts (not compatible with RT600 / 6600 series). Built from hardened steel and machined for precision, the kit focuses on safe, controlled removal of input shaft bearings to protect adjacent components and speed up service tasks. It’s aimed at technicians and DIY mechanics who need a reliable, long-lasting tool that avoids costly transmission damage.

How does this puller prevent damage to the transmission?

The Bonbo puller uses a controlled extraction design that grips and removes the input shaft bearing without levering against the drive gear teeth. Its parts align concentrically to apply even force, minimizing the chance of slippage or gear tooth deformation. Precision machining and hardened materials keep contact surfaces stable under load.

• Fits only 1 3/4" and 2" Eaton Fuller input shafts for correct alignment
• Even force distribution prevents gear tooth contact and chipping
• High-strength steel resists bending under extraction loads

What components come in the kit and how do I use them?

The kit includes the central forcing screw, bridge or yoke pieces sized for the two shaft diameters, and supporting collars that seat against the bearing. Assemble the bridge over the bearing, thread in the forcing screw and tighten to draw the bearing off the shaft. Use standard hand tools to operate — no hydraulic press required for typical removals.

• Forcing screw with durable threads for controlled turns
• Bridges and collars matched to 1 3/4" and 2" shaft diameters
• Easy hand-tool operation; avoids need for outside presses

Which transmissions and shafts is this compatible with?

This Bonbo puller is tailored for Eaton Fuller transmissions that use 1 3/4" and 2" input shafts. It will not fit Eaton RT600 or 6600 series transmissions, so confirm your model before ordering. If your vehicle uses other shaft sizes, a different puller will be required.

• Compatible: Eaton Fuller with 1 3/4" and 2" input shafts
• Not compatible: Eaton RT600 / 6600 series transmissions
• Check your transmission manual or measure the shaft diameter to confirm fit

How durable is the toolset and what maintenance does it need?

Manufactured from high-strength steel, the puller resists wear, rust and impact during regular shop use. The hardened forcing screw and precision-fit components maintain alignment and service life. Occasional cleaning and light lubrication of threads will preserve performance and prevent corrosion.

• Top-grade steel construction for wear and impact resistance
• Precision hardness and finish reduce deformation over time
• Simple care: wipe clean and lightly oil threads after use

Who is this for: The Bonbo Input Shaft Bearing Puller Kit is aimed at professional mechanics, fleet maintenance technicians, and experienced DIYers who service Eaton Fuller transmissions with 1 3/4" or 2" input shafts. If you need a focused, durable tool to remove bearings safely — and you want to avoid gear tooth damage and save time — this kit provides a purpose-built solution. Note: do not purchase for RT600 or 6600 series applications.
