Ty Mono - Front Fork Rebuild

Recommended Posts

A quick question? Does anyone know if a specialist tool is available to hold the inner fork mechanism when loosening the retaining bolt at the bottom of the fork leg?

I read in an earlier posting that people have mede them with a Hex bolt welded to a piece of steel bar? Does anyone know the correct bolt head size to use?

thanks

Rob

the hex bolt is 22mm across the flats and steel bar is 600mm long so can be done with forks extended if necessary

Many thanks, what do you recommend of the top end of the bar? Bend it off into a L to get leverage or weld another bolt on to lock with a socket??

thanks

22mm across flats? Sounds a bit wide to go through the narrow restriction inside the fork legs?

60north, you were spot on (as I am sure you know)... took the other one apart and I can confirm it is 22mm and their is no restriction.

Just need to get one made up now!

lineaway, I've tried to message you a couple of times and get a response that this member can't receive any new messages. Can you try to message me, I'd like to get in touch with through through email and see if you can send me some details on the YZ front wheel & disc that you mounted on your TY350. Thanks in advance. Sorry to everyone else on this thread.

I agree it is 22mm. I bought 2 22mm. nuts, drilled the threads out to just slide over a length of 1/2"rod and drilled through the nuts and rod and drove a 3/16 roll pin through and cut them off smooth. I have no access to a welder so that was my remedy which worked well.

Probably a bit late now, but may be of use to others...I found that a 1/2 inch drive spark plug socket ( the one I have happens to be 22m across the flats) turned upside down fits perfectly into the the damper rod...All you need then is a couple of 1/2 inch drive extenders with a normal wrench. No need for any welding or stuff...

I made a tool with nuts and bar as I have a welder, however I remember visiting a friend many years ago who was doing the forks and they simply rammed a wooden broom handle down the forks, the end had formed itself into a nice hexagon.

and#160;Find some one with an air gun. No special tool needed.and#160;

 

+1 on this suggestion. A pneumatic impact wrench works great for taking them apart and putting them back together.
