Part number 0555294 is a Gear Housing Gasket specifically engineered for use across a range of professional sprayer systems including the SprayTech GPX 85, PowrLiner 1800M and 2800M line stripers, PowrLiner 2850 GB_D_F airless striping system, and Advantage GPX 85 airless sprayer. This precision-cut sealing component is installed between the gearbox housing and its cover, creating a leak-proof barrier that contains lubricating oil within the gear drive system. The gear housing contains the reduction gears that transmit power from the motor or engine to the pump, and maintaining proper lubrication is essential for long component life and reliable operation.
The gasket is manufactured from materials specifically selected for compatibility with gear oils, lubricants, and the operating temperatures encountered in professional sprayer applications. It is designed to maintain sealing integrity under continuous pressure cycling, vibration, and thermal expansion. The precision-cut dimensions ensure proper alignment with bolt holes and sealing surfaces, preventing oil leaks that would lead to lubricant loss, gear wear, and eventual gearbox failure. This gasket is a critical component in maintaining the integrity of the drive system.
Gear housing gaskets are subjected to continuous compression, thermal cycling, and chemical exposure. Over time, they can become brittle, crack, take a compression set, or extrude from the joint. A failed gasket allows oil to leak externally, causing lubricant loss, gear overheating, accelerated wear, and potential gearbox seizure. Symptoms include visible oil leaks at the gearbox joint, low oil level, and increased gear noise during operation. Replacement with genuine 0555294 gear housing gasket restores proper sealing integrity and ensures reliable operation of the drive system across these professional sprayer platforms.

| Contamination Barrier | Blocks dirt and debris from entering the gear drive system |
| Pressure Maintenance | Maintains proper internal pressure for lubrication circulation |
| Visible Leakage | Oil seeping from gearbox cover joint during operation |
|---|---|
| Gasket Damage | Cracked, brittle, compressed, or extruded gasket material |
| Gearbox Service | Whenever gearbox cover is removed for internal inspection or repair |
| Preventive Maintenance | Replace during major drive system overhaul |
Part number 0555294 is specifically designed for the SprayTech GPX 85, PowrLiner 1800M and 2800M line stripers, PowrLiner 2850 GB_D_F airless striping system, and Advantage GPX 85 airless sprayer. The PowrLiner 1800M and 2800M are professional line striping systems for parking lots and roadways. The PowrLiner 2850 GB_D_F delivers up to 3300 PSI operating pressure for medium to large-scale striping projects. The GPX 85 models are lightweight, professional airless sprayers for residential and commercial applications. These units share common gearbox architecture requiring this specific gasket. This gear housing gasket is a model-specific component engineered for the sealing requirements of these particular sprayer systems. Always confirm fitment using the correct parts diagram for your exact model and serial number.

The gear housing gasket is typically replaced during gearbox service. When servicing, these related parts are often addressed at the same time.
The cover that the gasket seals. Inspect for flatness, warping, or damage to sealing surface.
Fasteners securing the gearbox cover. Replace if corroded or threads are damaged.
Lubricant for the gearbox. Replace with fresh oil of correct specification when servicing.
