I’m trying to disassemble the forks on my 48 Flyer. Out here in the colonies info on dowty forks is pretty thin. I did download a copy of the Panther manual but it seems slightly different than my forks. The first stumbling block is how do I get the pressure balance tube off? Does the “internal fitting top” unscrew from the balance tube? I tried that gently but was unsuccessful. At this point I can’t separate the two fork legs. I need to at least get the fork yokes off so I can clean and paint them. Of course the paint on the outer slider has long since turned to rust, have to fix that too.
Any help would be appreciated.
The balance tube is silver soldered into the top yoke and is an integral part of it. The top yoke can be lifted off as a unit once the down tubes and internal spindle have been removed. With the pinch bolt in the lower yoke loosened and the top nut removed the fork will come out. If you wish to dismantle the fork you will need a special tool to remove the nut holding the piston down in the tube. email me on my address in Yowl if you need a drawing and pics of the tool.
I’ve just read what I put and realised I was giving you a load of bum information.
The balance tube is soldered across the two centre tubes that go down into the forks. These are a push fit into the underside of the yoke and are held up into it by the top nuts. The yoke can be taken off the top without disturbing it, but I have found it easier to dismantle the forks from the bottom up, as the top can be difficult to get off if it is corroded or has been glued on to stop leaks. With the forks apart you are left with the two centre piston rods joined by a length of soft copper tube!
To dismantle the forks, take off the top nut, undo the pinch bolts and pull down the outer tube as far as it will go then use the special tool to undo the piston from the top of the lower leg down inside the tube. Lower leg and outer tube will then drop out of lower yoke. You can now lift off top yoke complete with centre rods, which can now be separated more easily if desired.
