Part number 800-262 is a Gear 2nd Stage used in the gearbox assembly of Airless Sprayer 1140I and IX, 840 I and IX, PowrTex 1200SF, and Performer 1140IX models. This gear is part of the multi‑stage speed reduction system that transfers power from the motor to the pump at the correct torque and speed. Replacing a worn, chipped, or damaged second stage gear restores smooth, quiet operation and reliable pump drive.

The 800-262 Gear 2nd Stage is an internal component of the gearbox in compatible airless sprayers. It is the second gear in a multi‑stage reduction train that slows the motor's high speed to the optimal low speed and high torque required to drive the pump piston.
Precision‑cut teeth ensure smooth meshing with adjacent gears, minimizing noise and vibration while transmitting significant force. Over time, gear teeth can wear, chip, or break due to fatigue, lack of lubrication, or debris contamination. A damaged second stage gear leads to increased noise, rough operation, loss of power, and eventual gearbox failure. Replacing it restores proper power transmission and extends the life of the sprayer.
| Speed reduction | Further reduces rotational speed from the first stage |
|---|---|
| Torque multiplication | Increases torque to drive the pump piston |
| Power transmission | Transfers mechanical energy through the gear train |
| Excessive noise | Grinding, whining, or clicking from gearbox |
|---|---|
| Visible tooth damage | Chipped, broken, or heavily worn gear teeth |
| Vibration | Unusual vibration during operation |
| Loss of power | Reduced pump speed or stalling under load |
Part number 800-262 is compatible with the following airless sprayer models. Always confirm fitment using the correct parts diagram for your exact model and revision.

When replacing the second stage gear, these components are often inspected or replaced at the same time to ensure complete gearbox reliability.
The gear that meshes with the second stage; inspect for matching wear.
Worn bearings can cause gear misalignment and noise.
Replace seals to prevent lubricant leaks and contamination.
