Fernando87mj Posted June 5, 2017 Share Posted June 5, 2017 Does anyone happen to know the size of the o ring that goes on the steering box end of the line , I tried searching but all I found was that end of the line was 18 mm , does that mean I need to look for a 18mm o ring ? Thanks. Link to comment Share on other sites More sharing options...
DirtyComanche Posted June 5, 2017 Share Posted June 5, 2017 No, it's a way smaller o-ring than that. My notes say the size is a -903, but that won't mean anything to most people. A hydraulic shop should know what that means, tell them it's for a hydraulic application that sees abuse. There's a GM P/N 26001594 that I believe to be correct. Rockauto lists a 10 pack for about $3 US (might be the price for one but you have to buy a box of 10?), so I'm thinking they are the ones. Link to comment Share on other sites More sharing options...
Fernando87mj Posted June 13, 2017 Author Share Posted June 13, 2017 Thank you for your response , I got the oring and replaced it . Turns out that when I replaced my high pressure hose I most likely over tightened the nut and split the seal . No leaks So lesson learned, when replacing hose , be gentle and tighten until it starts to get pretty snug .
