where are they leaking from??
They are leaking from the area around the bearing to inside rim? surface. The part where it would seem the rims come together but don't seal?
I had a similar problem on the nose wheel of my 701 project, the o ring was in the correct place but it still leaked. Not sure if my idea was a good one but I just used a can of tyre weld and spun the wheel round a few times then inflated the tyre to the normal pressure. It's been fine ever since. I guess the other answer is to split the rims and fit an inner tube.
The rims that I had from matco were not a great fit/seal even with the o ring.
Thanks, appreciate your help.
A little tire lube on the O ring helps to seat it into the center and then inflate to 32 PSI to seat every thing
Thanks, I appreciate your help.
Sometimes it is tricky to seal the split rims. It is critical that the o-ring does not have any twist in it which is tough to get it right. Also some o-ring lube or tire lubricant will help the o-ring seat.
I really hate tubes, so if I can’t get the one slow leaking rim that I have stopped, I am going to cure it by using pro-seal between the rim halves. Pro-seal is often used to seal riveted fuel tanks. That should fix it...
Another option is to run a small bead of RTV between the halves when when bolting together. Now do not forget the obvious as I did, a bad valve stem core.
