llhat Posted February 25 Share Posted February 25 From Cruisers tips (rip) anyone tried a small bead of RTV on a 'new' cap surface, then the new gasket? figure small bead let cure, then the new gasket, should make the fitment tighter trying a Stant cap this time (mi usa) instead of Motorrad or what can be obtained at FLAPS (mostly china) Almost want to try an O ring but figure it may not want to center.

AnotherOldJeepGuy Posted February 26 Share Posted February 26 I like the insert idea, but didn't read it before I did what I did. I bought a washer, rubber, polyurethane I think, at the hardware store that had the outer diameter just slightly larger than the original (only larger because they didn't have an exact OD match), and a little thicker, then used a hole saw to make the inner diameter match (although lots of other ways to make that cut). Not as cheap as using a spare tire tube insert, if you have or can dig up one. If you need to purchase, the washer is cheaper than buying a tube. No more leaking. Also if your leak is due to the original washer being cracked or dries out, the insert may not be good enough, this will cover that situation also.

Whitaker717 Posted February 27 Share Posted February 27 On a side note to that anyone know where to buy just the rubber washer? I’m heading down this road too. Not sure where or what size to buy. Link to comment Share on other sites More sharing options...
llhat Posted February 27 Author Share Posted February 27 unknown, but.... Here's measurements from a NEW Stant part# 10085 unit OD 1.77" 45.2mm ID 1.05" 26.6mm THK 0.09" 2.4mm (taken with harbor freight digital caliper) Link to comment Share on other sites More sharing options...
AnotherOldJeepGuy Posted February 28 Share Posted February 28 NAPA sells a new cap, PN 703-1366, that comes with a new washer, and for some reason I have one I must have purchased at some point, don't really remember when or even why since it is still in the box and not in the Jeep. But I don't think they sell the washer alone. And that washer didn't seal tight when used on the original cap or on the new cap (the original wasn't all that tight either though). So that lead me to making one a little bit thicker that was snug. I got the washer at Elliott's Hardware, but other HW stores should have it. just take the dimensions from @llhat with you and match it up. Link to comment Share on other sites More sharing options...
llhat Posted February 28 Author Share Posted February 28 i have not checked fitment on the new Stant Cap as of 'now' , it also was not installed on the new cap, but in the box. I do not know how the washer measurement compares to the NAPA part number. I've an 'old time' hardware store here, have not checked it for similar washer.

AnotherOldJeepGuy Posted February 28 Share Posted February 28 Lots of freedom in the measurement. My first attempt was using a toilet fill valve washer I already had. Size was pretty good actually but the rubber was a bit too squishy. ! Link to comment Share on other sites More sharing options...
llhat Posted February 28 Author Share Posted February 28 and one has to be concerned with the effect of heat and oil on the material... yeah there's room for tolerances.... wanted to give a starting point on a new, unused gasket. Link to comment Share on other sites More sharing options...
