4rt Fork Damper Tube Holding Tool

Featured Replies

Does anyone know what type and size of end is required on a tool to hold the front fork damper rods when reassembling ??

hi oz thumper

i use a tyre lever which is about 30 inches long

pushing down the tube, then tighting the bolt at the bottom

hope this helps

put the spring in and compress it, this will hold the damper rod in place so you can tighten the bolt

I made one from plastic tube but don't know where I put it, will try and dig it out later.

That would be for the right hand leg Nigel?

I have completed the left leg and found that it has a bi-hex socket as part of the damper casting, all that is required there is a hex head bolt (or nut) that is 24mm across the flats, welded to a piece of rod about 250mm long.

A 16mm metric bolt or 5/8 Unified have a hex head around 23.5mm and fit fine.

I haven't stripped the right leg yet so haven't seen what is required other than it must be tubular to go over the damper rod.

If you do have a photo of the tool you used Nigel, will be appreciated.

I have a Brand New right hand fork tube for a 4RT. There is a small dent just below the top triple clamp but will not affect the operation at all. If anyone is interested drop me a line.

Yep right leg. Think it only needed the slightest holding before it bit with a cordless .

can't find it yet, sorry.
