DAYUAN Pull-and-Press Sleeve Kit 28pc — 34–72mm & 44–82mm Sleeves, 40CR Steel Case

DAYUAN’s 28-piece pull-and-press sleeve kit is a complete, heavy-duty set of sleeves and accessories for removing and installing bushes, bearings, and seals safely and accurately.

This kit collects a broad range of matched sleeves and drivers so technicians and DIYers can press out worn components or fit new ones without hammering, bending or damaging housings. Built from heat-treated 40CR steel with a black-oxide finish, the parts resist rust and handle high loads while the molded carrying case keeps every piece organized and transportable. The sleeves cover a precise size range to adapt to many HGV and LCV engine service tasks and suspension repairs.

Which repair jobs can this DAYUAN sleeve kit handle?

The set is designed for pressing in and pulling out bushes, bearings, and seals found in heavier vehicles and light commercial engines. It reduces the need for improvised tools and lowers the risk of deforming mating surfaces. Use it for suspension components, engine mounts, steering linkages and other cylindrical-fit parts.

• Removal and installation of bushings in suspension arms and linkages
• Bearing extraction and fitting for wheel hubs and small gear housings
• Seal seating and replacement without damaging lips or housings
• Compatible with standard workshop presses, pullers and hydraulic drivers

How do the sizes and materials support accuracy?

The kit includes a graduated set of internal and external sleeves that increment in 2 mm steps across a wide range. Machined from 40CR alloy steel and finished with black oxide, the components offer consistent concentricity, strength and corrosion resistance for repeated service use.

• Internal diameters from 34 mm to 72 mm in 2 mm increments
• External diameters from 44 mm to 82 mm in 2 mm increments
• 40CR steel construction for high load-bearing and wear resistance
• Black oxide coating to reduce oxidation and extend tool life

What accessories and safety features are included?

Beyond the sleeves, the set is supplied with the adapters, spacers and collars needed to pair with standard presses or threaded pullers. A reinforced blow-molded case protects parts from impact and keeps them sorted to speed job setup in busy workshops.

• Full complement of drivers, spacers and collars for common workshop presses
• Sturdy blow-molded storage case for safe transport and organization
• Parts labeled and nested to prevent mix-ups during use
• Designed to minimize accidental damage to housings and bearing races

How will using this kit change my workflow?

Replacing improvised pounding with matched pressing halves reduces rework and saves time. The correct sleeve sizes concentrate force where needed, cutting press cycles and lowering the chance of crushing or scoring critical surfaces. Technicians find faster turnarounds and fewer returns on fitment-related failures.

• Faster set-up with organized, size-marked pieces
• Cleaner, controlled presses for repeatable results
• Reduces risk of damage to housings, seals and bearing seats
• Portable kit for field or garage repairs

Who is this for: The DAYUAN 28-piece pull-and-press sleeve kit is intended for professional technicians, mobile mechanics, and serious DIYers who work on heavy goods vehicles, light commercial vehicles, or automotive suspension and engine components. If you need a robust, repeatable way to remove and fit bushes, bearings or seals without risking component or housing damage, this kit provides the sizes, strength and storage to make workshop and roadside jobs faster and more reliable.
