Product Description
A760E A760F A760H A761E A960E A960F AB60E AB60F O-Ringed End Plug Kit
Sonnax Part Number: 147741-30K
The primary design function of the OE end plug in listed Toyota/Lexus units is to prevent critical pressure loss by capping the bore. OE end plugs rely entirely on small clearances between the end plug and bore to confine hydraulic fluid under fluctuating pressure. End plugs are often tasked with a secondary role functioning as a spring stop or valve stop.
The repetitious and varying actions of fluid pressure, spring motion and valve impact cause wear at the end plug and bore mating surface and can distort the shape of the end plug. High pressure fluid leaking through the clearance gap can, with time, erode the surface material of both end plug and bore. Eventually the cumulative loss of hydraulic integrity leads to low pressure in critical circuits. Complaints vary depending on the location of the worn end plug but are always related to pressure losses.
Sonnax O-ringed end plug kit 147741-30K replaces worn, distorted or eroded end plugs in Toyota/Lexus A760, A960 and AB60 series units. The Sonnax end plugs have small clearances to mechanically block the bore and increase effectiveness. The O-ring seal reduces leakage further by blocking off worn areas of the bore which the new end plug alone could not seal.
- Minimal end plug-to-bore clearance with added O-ring for positive seal
- Drop-in Zip Valve™ parts install quickly and easily
