Universal press & pull sleeve kit Masuma, 36–82mm, PR-105

No data

The Masuma PR-105 universal press & pull sleeve kit is designed for safe, efficient, and precise removal and installation of suspension bushings (silent blocks). It is compatible with most passenger vehicles and allows bushing service without removing the control arm from the vehicle.

Application Instructions

1. Select the appropriate sleeves based on the size of the bushing. One sleeve should match the outer diameter of the bushing, while the other must be slightly larger than the inner diameter of the housing.
2. Install the sleeves onto the support discs according to the letter markings.
   • Gold-colored sleeves go on side "A"
   • Silver-colored sleeves go on side "B"
3. Choose a suitable guide spindle that closely matches the inner diameter of the bushing to prevent bending during the operation. Always apply ample lubrication to reduce resistance and prevent spindle damage.
4. Assemble the tool, placing the sleeves and support discs on both sides. Hand-tighten the nuts, then use a wrench to turn the bolt until the bushing is fully pressed into the sleeve. The sleeve system distributes the load evenly along the outer shell of the bushing, enabling controlled extraction from the control arm. A U-shaped cutout in the sleeves allows visual monitoring of the extraction process.

Note: If the bushing resists removal, stop the process, disassemble the tool, apply penetrating lubricant to the contact surfaces, and repeat the procedure.

5. To install a new bushing, follow the same procedure, reversing the positions of the gold and silver sleeves.

• Ensure proper alignment to avoid deformation.
