Weeping at the Sight Glass
« on: May 02, 2011, 04:03:07 PM »
My bike weeps oil at the sight glass.  It is just a slight leak, runs under the engine and drips a drop or two.  I thought it was the o-ring or the drain plug, changed those twice before I figured it was coming from somewhere else.

I guess I have the only RE that leaks oil, just my luck.

Well, they used to be called Royal Oilfield!  ;D

But the UCE certainly seems good and tight, mine certainly is.

Yes, ask him what he thinks.  Actually I talked with him several months ago about this problem, he said he had never seen one with a leak like that, maybe he has more information now.

I have a small house on Grand Lake, travel thru Tulsa often.  Maybe I could drop you a line, we could meet in Tulsa for lunch.  Never seen another RE on the streets of Oklahoma.  You know what Tulsa spelled backwards is, right?

Cheers,

This is going to BE a problem if not addressed. The sight glass pushes into the case from the OUTSIDE and has no mechanical fixture to hold it there, other than a little friction on the rubber sealing ring. Any oil that gets past it is going to wet the seal and make it MORE prone to removing itself under the slightest crankcase pressure. I sent one flying across the room with 8psig as a test ...  I made the suggestion that the sight glass should have an e-clip or a circlip or SOME sort of mechanical fixture to it .... but I guess a dozen or so "hard" improvements were enough.

I'd take the thing to a machine shop and have a groove cut around the inside of the sight glass hole to allow mechanical fixing of the thing. That way, if it DOES leak - it isn't going to pop out and toss all the oil all at once .......

Scooter Bob - Thank you for your reply.  I think I am having a heart attack!   Bike only has 1291 miles, MFR Date of Jan 2010.  Was planning a 300 mile ride on old Rte 66 in early June with some pre 1975 bikes, was planning to show them what an Enfield could do!  Maybe I need to think about this a little.

we've had 1 sight glass weeper.
KH suggested we replace it ASAP for the reason SB mentioned.
after tapping the leaker out, we found the o-ring or seal was distorted
showing it was put in a bit crooked.
easy fix, we had the sight glass and gasket in stock
thanks to SB suggesting it during our school.

For you "do it yourselfers" - I think either CV Products or maybe even Summit Racing has the spiffy little "cut yer own" circlip groove cutting doo-dad for pretty cheeeeep. I cheated and used a small boiler tube sheet roller on the Military bike that I just did (use what you got .... it's an old family tradition ....). It made enough of a groove to accept a wrist pin circlip that I had that was pretty close (again UWYG!) and it was done in a jiffy. NOW it'd take significantly more than 8psig to get it out of there - even if it IS leaking.

I had also entertained putting a "retaining ring" over the glass (PVC tubing would do well ...) and securing THAT with a couple of small button head screws on the perimeter. It wouldn't take much to get peace of mind. That design is a total rookie mistake, I think ..... I was absolutely STUNNED that it went in from the OUTSIDE .... stunned ...
Spare the pig iron - spoil the part!

OK, i have to mirror Andy on this one.  :o  Last thing I want is catastrophic failure doing 65, 200 miles from home. TW, i know you're about 200 miles away from Ron's. You think you will be able to get it up to him in time for the run? I'm going to keep an eye on mine as well as they both may have been manufactured at the same time in India, probably on friday. Keep us up to date.
