Dewalt 90591435-01 Reciprocating Saw Shaft Assembly

Product Description

The DEWALT 90591435-01 is a replacement reciprocating shaft assembly designed for the P3 series reciprocating saw platform. This OEM service part restores the core stroke mechanism that drives blade movement in DEWALT reciprocating saws. The assembly is sized for the small (SM) configuration and provides a 1-inch stroke length, which is the critical dimension governing how far the blade travels per cycle. Licensed technicians and authorized service centers install this component during drivetrain rebuilds or when reciprocating motion is lost due to shaft wear or damage.

This shaft assembly is intended for use in DEWALT P3 platform reciprocating saws requiring the small-frame stroke shaft. It is a service and repair part, not a blade or accessory, and is appropriate for professional tool repair shops as well as field technicians performing in-house equipment maintenance on DEWALT power tools. Proper identification of the small versus large frame configuration is essential before ordering.

Key Features

• OEM DEWALT replacement shaft assembly for accurate fit and function
• 1-inch stroke length governs blade travel distance per cycle
• Sized for small (SM) frame configuration within the P3 reciprocating saw platform
• Restores reciprocating drivetrain function after shaft wear or failure
• Direct OEM part number reference eliminates cross-reference guesswork

Compatibility

Designed as an OEM-style replacement shaft assembly for DEWALT P3 platform reciprocating saws in the small frame configuration. Verify frame size and platform designation against the tool nameplate before installation.
