Crankshaft for 1099XPA Air Ratchet

This Ingersoll-Rand 109XPA-35 crankshaft is a genuine replacement part designed specifically for the 1099XPA air ratchet wrench. It restores the tool’s drive mechanism when the original component has worn or failed. Professional technicians and DIY users who rely on this ratchet for daily fastening tasks will find it returns the tool to factory operation.

Dimensions and fit

The crankshaft measures 2.6425 inches by 1.924 inches by 0.5 inches, matching the precise geometry required by the 1099XPA housing. Because it is manufactured to the original specifications, installation does not require modification or adjustment of surrounding parts. Correct fitment maintains the intended clearances and rotational balance of the pneumatic motor.

When to replace the crankshaft

This part replaces a damaged or worn crankshaft inside the 1099XPA air ratchet, addressing loss of power, unusual vibration or mechanical binding. The upgrade is worthwhile when the tool’s motor still holds pressure but the drive train no longer transfers torque cleanly. It is not for users needing a complete ratchet assembly or a different drive size.

Questions about this item

How do I install the 109XPA-35 crankshaft into the 1099XPA air ratchet wrench, and what step is commonly missed?

The crankshaft fits the 1099XPA air ratchet wrench; a common error is failing to align the 2.6425" x 1.924" x .5" dimensions with the housing bearings before securing the end plates.

What maintenance or replacement will the 109XPA-35 crankshaft need during its service life?

Inspect the crankshaft journals for wear during routine air ratchet servicing; replace if scoring or excessive play appears on the 1.924" diameter bearing surfaces.

What is the first limit that appears when the 109XPA-35 crankshaft runs under sustained load?

Heat buildup in the 1099XPA gear train typically limits continuous duty before the 2.6425" long crankshaft reaches its material fatigue threshold.
