EWK Adjustable Battery Terminal & Wiper Arm Puller 8–30 mm — Spring‑Assist, T‑Handle for Safe Straight‑Line Extraction

The EWK Battery Terminal and Wiper Arm Puller is an adjustable, spring-assisted tool that safely and cleanly removes seized wiper arms, battery terminals, and small press-fit parts from 8–30 mm bases.

Built for automotive technicians, DIYers, and detailers, this compact puller delivers straight-line force while protecting windshields and posts from damage. Its adjustable jaws and precision center screw let you grab components securely and extract them without pry-bar slips or hammer shocks. Constructed from medium carbon steel, the tool balances durability with a lightweight form that fits into crowded engine bays.

How does this puller protect glass and terminals during removal?

Unlike makeshift methods that risk chipping or cracking, the EWK tool locks onto the part and pulls evenly along the shaft axis. The spring-assisted self-locking jaws hold the component steady so the center screw supplies controlled, centered pressure. That combination reduces bending forces and prevents sudden slips.

• Self-locking jaws prevent slipping under load
• Centered screw applies straight-line extraction
• Fits parts with at least 1 mm clearance beneath the arm
• Removes seized parts without hammer strikes

What size parts will this adjustable puller handle?

The jaw gap adjusts to grip bases measuring 8–30 mm (5/16"–1-3/16"), covering the majority of passenger cars, trucks, and SUVs. That range makes it suitable for front and rear windshield wiper arms plus many battery terminal configurations. Small press-fit components like bushings, pinions, and washers are also within its capability when the clearance and geometry permit.

• Adjustable jaw range: 8–30 mm
• Works on most wiper arm bases and many terminal posts
• Ideal for parts with 1 mm minimum clearance beneath the arm
• Also removes small bearings, pinions, and bushings

How easy is it to use the puller in tight engine bays?

EWK designed the puller for one-handed operation: tighten the integrated T-handle to apply steady pulling force without extra tools. Its compact footprint and straight center screw make it simple to position even where space is limited. The spring-assisted mechanism locks on, holding the grip while you turn the handle for controlled extraction.

• Integrated T-handle for single-handed tightening
• Spring-assisted jaws maintain grip while you work
• Low-profile frame fits cramped engine compartments
• Precision screw delivers smooth, even pulling force

How durable and reliable is the construction?

The frame and jaws are made from medium carbon steel chosen for repeated high-force use without bending or permanent deformation. The parts that handle the load are heat-treated and machined for consistent alignment and long service life. This sturdiness keeps the tool dependable day after day in a busy shop or garage.

• Load-bearing frame and jaws of medium carbon steel
• Engineered to resist bending under repeated force
• Precision machining keeps pull centered and balanced
• Designed for professional and home mechanic use

Who is this for? The EWK Battery Terminal and Wiper Arm Puller is for automotive technicians, detailers, body shops, and DIY enthusiasts who want a safe, compact tool to remove seized wiper arms, battery terminals, and small press-fit components without risking windshield or post damage. If you need a reliable, adjustable puller that fits tight spaces and performs consistent, one-handed extractions, this tool is a practical addition to your kit.
