Water pipe o rings

Postby 702scottc » Sun Sep 13, 2015 11:38 am

Has anyone had any experience replacing the water pipe o rings without removing the intakes and carburetors? If so, what is the procedure? I have an occasional seep from the right hand pipe where it fits into the cylinder head. Not a major source of concern at this point but I'm going to have to address it Eventually.

hi 702scottc. I dont know about doing this job without taking out the airbox, carbs and manifolds. its a time consuming task, no doubt as took about 8 hrs to do mine about a month ago. I also has a slight "weep" leak (onto the block) but from the other end leading into the thermo housing, as a result of pitted "o" rings on both pipes feeding the cylinder heads from the the thermostat. All four had signs of pitting and failure due soon so I recommend doing whole job right and also allows you to check all the other small hoses as well under the carbs while you can access them. Only the lower block "o" rings to go at next coolant change. As I am in Australia and do not have a need for carb heating in winter (no snow), I swung a new piece of hose across between the coolant pipes, bypassing and removing the thermo valve circuit and about 10 older spring clamps (possible leak sources) and placed new worm drive SS clamps on the new hose so to increase reliability in the old girl for summer riding (40+). your question three months old now but my 2 cents worth and hope useful... Ps my 1988 1500 has 51K on it and rides smooth as, very happy now no more coolant leaks.

Yeah, 702scottc. I am there right with you. Seems like a bear. Since so much work has to go into this project, when I attack this, I am going to probably remove the carbs and get them overhauled. In addition, replace all the rubber I can at that time. Including the vacuum hose underneath the rubber matt.
