Gashwer Wiper Arm & Battery Terminal Puller Tool Kit — Heavy‑Duty 45# Carbon Steel, Dual‑Function Remover

Gashwer's heavy-duty puller is a dual-purpose workshop tool that safely removes windshield wiper arms and battery terminal clamps without damaging splines or posts.

Whether you're a professional mechanic or a DIY car owner, this compact puller set combines robust construction with a simple, controlled extraction method. Made from heat-treated 45# carbon steel, the kit includes both a jaw-style wiper arm remover and a dedicated collar-style wiper arm remover, plus a center screw designed to seat on tapered spline posts and battery terminals. The design reduces marring of hood fairings and prevents bending of delicate wiper components during disassembly.

How does this tool remove stubborn wiper arms without harming parts?

The Gashwer puller uses a centered screw and precision jaws to apply even, axial force to the wiper arm base so the arm lifts straight off the spline. The screw pad is shaped to sit on top of the spline post, and the jaws clamp the arm body firmly, preventing sideways slipping that can mar paint or bend the arm.

• Centered screw pad fits spline tops for direct pull force
• Forged, heat-treated jaws resist bending and keep a secure grip
• Two removal styles included for tapered-spline and bolted-on arms
• Compact footprint allows use in tight engine-bay spaces

Can this puller handle battery terminal clamps as well as wiper arms?

Yes — the puller is designed for dual use: its central screw and jaw geometry let you extract battery terminal clamps without exerting damaging torque on the post. Because it applies straight pulling force, it reduces the risk of cracking or bending battery posts and helps preserve clamp shape for reuse.

• Screw pad spreads load across the top of the battery post
• Jaws hold clamp ears securely to prevent slippage
• Works on a wide range of clamp sizes within the jaw opening range

What sizes and materials define the tool's durability and fit?

The puller is constructed from 45# carbon steel with a special heat treatment that increases hardness and corrosion resistance for long service life. Its jaw opening accommodates components from 1/16" up to 1-1/16" (6–28 mm), and the overall outer diameter measures about 1-7/8" (48 mm), making it suitable for most passenger vehicles.

• Material: 45# carbon steel, forged and heat-treated
• Jaw opening: 1/16"–1-1/16" (6–28 mm)
• Outer diameter: approximately 1-7/8" (48 mm)
• Includes collar remover with ~15.2 mm collar size

How do you use the puller safely and effectively?

Position the puller feet so they sit securely beneath the wiper arm or clamp, center the screw onto the spline or battery post, then turn the screw steadily to extract the part. For bolted wiper arms, use the included collar-style remover where appropriate; always work slowly to avoid sudden releases that can cause damage or injury.

• Ensure feet are clamped under the arm flange before tightening
• Keep the screw centered on the post to avoid side loading
• Turn screw evenly; avoid sharp impacts or hammering
• Inspect parts after removal for wear before reinstalling

Who is this for: The Gashwer Wiper Arm and Battery Terminal Puller is aimed at professional technicians, auto-body shops, and serious DIYers who need a reliable, low-profile extractor for routine maintenance and repair. It’s especially useful where space is limited or where protecting the wiper arm finish and surrounding trim is important. The kit’s hardened steel construction and dual removal options make it a practical addition to any automotive toolset.
