Air Riveter Service Kit Air Cylinder (20/34-36) For At0018

At a Glance: Air cylinder service kit for the AirCraft AT0018 Air Hydraulic Riveter—refreshes the cylinder assembly for consistent pull cycles and dependable workshop performance.

The AirCraft AT0018-SK08 Service Kit is a cylinder-focused rebuild kit for the AT0018 Air Hydraulic Riveter. The air cylinder is a major working section of the tool—controlling movement and helping drive the cycle that delivers pulling force on the mandrel. When the cylinder assembly becomes worn or damaged, you can end up with sluggish cycling, inconsistent operation, leaks, or a riveter that simply doesn’t feel as strong and predictable as it should. This kit replaces the designated air cylinder components (item 20 and items 34–36) to restore correct fitment and stable operation. It’s the right service kit when the cylinder section needs attention—whether from high-use wear, impact damage, or as part of a more complete riveter overhaul.

In an air-hydraulic riveter, repeatable movement is everything. Refreshing the cylinder assembly helps maintain proper alignment and pressure behaviour, delivering smoother cycling and more consistent riveting results.
