VEVOR Bearing Separator & Puller Set ZX-B012 Manual

Introduction to the VEVOR Bearing Separator & Puller Set ZX-B012

The VEVOR Bearing Separator & Puller Set ZX-B012 is a heavy-duty mechanical tool kit designed to remove tightly fitted bearings, gears, pulleys, pinions, and similar components. Its separator jaws grip behind the component while the puller assembly applies controlled mechanical force, helping reduce the risk of prying, hammering, or damaging nearby shafts and housings.

This 14-piece bearing splitter tool kit includes two adjustable separator sizes, puller legs, extension screws, a lead screw, and a yoke. The smaller separator adjusts for components approximately 30–50 mm in diameter, while the larger separator accommodates approximately 50–70 mm components. This range makes the set useful for many automotive, ATV, light-truck, agricultural, and workshop maintenance tasks.

Constructed from 45# steel with a black-coated surface, the kit is intended for repeated workshop use. Its rated pulling capacity is up to 5 tons when used correctly and when the load is properly aligned. The included storage case helps keep the bearing puller components organized between jobs.

This guide is intended for mechanics, maintenance technicians, hobbyists, and DIY users who need a practical bearing removal tool. Always confirm the component size, available clearance, thread condition, and required force before beginning work.

The knife-edged separator profile is designed to fit into limited clearance behind a component. Performance depends on correct jaw placement, straight alignment, thread lubrication, and the condition of the part being removed. The 5-ton rating is a maximum tool capacity, not a guarantee that every component can be removed without additional preparation.

How to Set Up and Use the Bearing Puller Set

1. Park the vehicle or machine securely, switch off the power, and support the assembly with approved stands or fixtures.
2. Clean the exposed bearing, shaft, and surrounding area. Remove retaining rings, collars, keys, bolts, or other parts that prevent removal.
3. Measure the component and select the separator that fits behind it. Use the smallest suitable separator whenever clearance allows.
4. Loosen the separator fasteners, position both jaws evenly behind the bearing, and tighten them so they sit firmly under the inner race or strongest supported surface.
5. Install the puller legs and yoke. Add extension screws only when necessary to reach the separator while maintaining a centered arrangement.
6. Place the lead screw against the shaft end. Use a protective cap or suitable spacer if the shaft could be marked.
7. Check that the separator, legs, yoke, and lead screw are aligned. Turn the lead screw gradually with the correct wrench.
8. Pause frequently to confirm that the jaws remain seated and the component is moving evenly. Apply penetrating lubricant or controlled heat only when appropriate for the material and assembly.

Do not use an impact wrench unless the exact product instructions explicitly permit it. Wear eye protection and gloves, keep hands away from pinch points, and never exceed the tool’s rated capacity.

Troubleshooting the ZX-B012 Puller Kit

Separator slips from the bearing

Stop applying force, release the load, and reposition the jaws evenly behind the strongest supported surface. Clean oil, rust, and debris from the contact points. Do not continue if the separator is visibly bent or damaged.

The bearing does not move

Verify that all retaining hardware has been removed and that the puller is centered. Apply penetrating lubricant, allow time for it to work, and increase force gradually. If resistance remains excessive, use a larger approved puller or seek professional assistance rather than exceeding the 5-ton rating.

Lead screw is difficult to turn

Clean and lubricate the threads, check for cross-threading, and confirm that the load is straight. Replace damaged or deformed components before reuse.

Uneven movement or tilting

Release the load and adjust the separator and puller legs so the force is distributed symmetrically. A tilted setup can damage the component, shaft, or tool.

Error codes and electronic faults

This mechanical bearing puller has no electronic display or documented electronic error-code system. Mechanical binding, slipping, bent parts, and abnormal thread resistance should be treated as warning conditions.

Inspect the set after every demanding job. Store the parts dry, wipe away contaminants, and protect the lead screw threads with a light suitable lubricant. For warranty, replacement-part, or product-specific support, use the seller or manufacturer contact details shown on the purchase record, product listing, or supplied documentation.

Pros and Cons of the VEVOR Bearing Separator & Puller Set ZX-B012

Pros

• Versatile size coverage: Two adjustable separator ranges support many common bearing, gear, and pulley dimensions.
• High mechanical capacity: The stated 5-ton capacity suits many automotive, ATV, and light-truck maintenance tasks.
• Complete working set: Puller legs, extension screws, separators, lead screw, and yoke are supplied together.
• Durable construction: 45# steel is appropriate for demanding manual workshop applications when used within its limits.
• Organized storage: The case helps prevent misplaced components and simplifies transport.
• Controlled removal: A separator and puller can apply steadier force than improvised pry bars or repeated hammering.

Cons

• Limited size range: Components outside approximately 30–70 mm may require a different separator or larger puller.
• Manual operation: Removing seized parts can require significant time, lubrication, careful alignment, and physical effort.
• Clearance requirements: The separator must fit behind the component; flush-mounted or inaccessible bearings may need another removal method.
• Not a universal puller: It is less suitable for internal bearings, extremely large assemblies, or applications requiring hydraulic force.
• Alignment-sensitive: Incorrect positioning can cause slipping, thread damage, or bending.

The VEVOR Bearing Separator & Puller Set ZX-B012 suits vehicle repair, equipment maintenance, and general mechanical workshops. Users working on oversized, internally mounted, or severely seized components may need a specialized hydraulic, internal, or higher-capacity puller system.
