That "Screw Plug" has an o-ring on it. On the older ones the o-ring would kinda disintegrate. A hardware store o-ring was a worthy upgrade.If it keeps leaking replace em.CJ
I don't know what purpose a plug under a plug would be but there is no extra plugs on my G5.The hex under the plug on mine is for unscrewing the fork tube from the upper tree.CJ
There is no plug under the slotted chrome top plug on the G5. At least not on my G5. I have previously removed the chrome plug to check the fork oil level with a wire dip stick - only one plug to remove.
Sigh JI can you post a picture of the exploded view of the fork assembly from the service manual, that would give a clear picture to what parts are on the assembly.
The hex I was referring to is actually made right in to the top of the fork tube. And if you can screw it one way or another then your fork tube is loose.After it is screwed all the way up the pinch clamp in the lower tree is tightened so it won't unscrew itself.Don't know if the C5 is different but change doesn't seem to happen at REM often.CJ
Somewhere down the line RE has changed the design of the end caps and rods of C5 fork or there is a difference between the domestic and export C5 suspension.In one diagram it has 4 parts of a assembly of a end cap of the fork where as Will said that he can unscrew the flange bolt and he's absolutely right and I am not lucky enough like Will to unscrew the bolt to check or feed oil into the rod. For me the whole suspension has to come out to put some fresh oil.
Yup, My C-5 has a different design. Sorry to add any confusion. But intersting stuff though. You got it !, Singh
Thanks Singh Ji for the pictureHere I have attached the two different C5 suspension setup.
I had a similar leak on my '04 Sixty-5. It has a little O-ring at the very top of the fork. If tightening up the tube and replacing the O-ring in the cap doesn't get it you will have to pull the top tube and replace that little sucker.
G5 seems like a much simpler design. As you say the cap on yours was loose so looking at it I think the leak should stop since you have tightened it. If it doesn't then just change the O-ring.Can anyone shed some light to why there are two different design for C5 rods?
Leonard:Thanks for your post and the picture. In my G5, there is no such round threaded hole on the top of upper fork. There is only a flattened hexagonal hole on which the tip of the Top Srew Plug sits. Do you have 2 plugs - one on top of the fork, and another on the headlight casing ?
Only one plug that goes in the visible threads. The hexagonal hole is down there, you can just make out one side if you look close. The O-ring I'm referring to isn't visible unless you unscrew the top tube.
