Hi all,
I’ve just stripped my YPVS forks down after fully rebuilding them with genuine seals and bushes etc.
I wasn’t 100% happy with the chrome on the stations. They looked OK when I built them, but after leaving the rolling chassis in the rain a few times (to make space in the garage to work) I noticed a few tiny pin pricks of rust just starting.
I stripped them back today and what a hassle.
The screw holding the damper rod in just spins the damper rod when you try to undo it.
I know some FZR’s have a hex socket in the damper rod, but the YPVS doesn’t.
Had to drill the screws out in the end. There must be a better way?
Maybe machine the damper rods to accept a hex or similar?
Jon

Yes a pain in the ads when the rod spins
I usually get an allen socket and a few 3/8 extension bars down on-site to get some pressure on the rod, doesn't take much
The correct tool is like a tapered barb

I usually find an impact gun will shift them, I've had a few stubborn ones over the years, a real pain in the bum.

I could make such a tool for next time. A morse taper holds things in my lathe tighter than expected. A rod of the right taper, held in a vice and tap the forks onto it to bind the damper rod would be a good idea. Thanks. Jon |

Impact wrench plus loosen them first of all while the fork is complete. This way the spring is pressing on the damper rod helping prevent it from rotating.

Had the same thing last week, tried everything and still the damper rod turned, broke out the impact gun and it span 'em straight out.

The investment of around a tenner does away with all that pain, just ignore the offensive language at the top of the link  - Thingy

Link to shopI can see the proper tool, but can’t work out how to hold it still. Clamped in a vice maybe? Jon |

Usually a t bar on the top of it Steve Yep, extension with T bar, a light tap on the end of the extn then lay the fork flat the T bar holds it's self. You can also but a one piece tool for about £15 with an L handle on top, basically it's just a length of 1/2" bar machined down to a taper at one end and bent to 90 degrees at the other. |

I had this problem in the past with Gsxr forks. A Gixxer forum member at the time recommended shamferring down the end of a wooden broom handle and jamming it into the top of the damper rod. Worked a treat !! Once apart I made a special tool that was basically a T bar with an upside down bolt on the bottom end. The bolt head fitted the hex on the top of the damper rod so it could be held securely. Gotta say the broom handle was just as good though Dusty  |

I did the seals on my YPVS forks the other week and used some wooden dowel that i think was once a curtain rail, worked just fine for me.

Crack the bolts with an impact wrench whilst still assembled or even on the bike.. (using a front stand of course)
Never had some needed drilling out.

Impact gun always worked for me when they spin. I don't have a gun but my local friendly dike shop undoes them for me when I'm struggling.
