Is this acceptable wear....fork pins

[Guest]

I was fixing to drill my fork on the cross shaft and looked closely at the two pins that engage the throwout bearing. There is an awful lot of wear on one of the two pins. They both show signs of wear but pictured is the worst. I don't want to have to take this tranny out again any time soon and wondered if I am in the market for a new for. I know the pins can be replaced but getting these in and out is not that simple. Easier to just put in a new fork. This fork has about 15K miles on it. I changed it with my last clutch. It rides on a Koyo bearing. Change it and sleep better? What do ya'll think?

Bill, I've got a new fork and pins in my spare parts bin, but I'm on my way to mass & then dinner, so I'll post pics later, if no others show up.

Paul, I went ahead and ordered a new fork online with TRF. That is assuming they have one. Moss had none. I will call TRF Monday to see if indeed it was in stock. I kinda suspect that the wear is close to being ok, but the amount of stress put on those pins makes me think that this one is fixin to go.

I can just imagine how much wear is put on the Gunst bearing with constant contact, eh?

(Say a prayer for me.)

I think you did good to order new.
That photo looks like the Crypt Car's
fork pins.

And we all know how reliable Crypty is.

Those pins of yours are definitely worn, as you will see in the pictures below.

Bill, let me know if you get in a bind. I have (4) spare pins and a new TRF fork assembled (with pins) that I can send to you, until yours gets in if you are in a hurry to go back together.

I also have a spare new cross shaft, bushings and the long taper pin you lock in through the shaft, then wire down in place. I had mine spot welded just to be sure, once everything was lined up and working perfectly.

If TRF is on backorder, I'll send you whatever you need and you can replace it when it comes in.

Selfish of me, but I saw your rivet set in your photo.

What do you use those for, and how do you do it??

Hi Bill,

I've seen a lot worse worn pins that what's shown in your photo.

Rather than replace the pin or the entire fork, just grab the pin with a pair of vice grips and rotate it 90 degrees. That way a fresh, new surface will interface with the slot in the TO bearing carrier. Smear a bit of grease in the slot, too, to help keep the pins from wearing so heavily.

The first time I saw the pins were worn, I rotated them 90 degrees as Alan suggests. Later I bought new pins. The next time I had it apart, I put the new pins into the existing yoke. Its still the original yoke with 174,000 miles in it.

Thanks Paul. I will call TRF in the morning to see if indeed they have the fork in stock.

You think maybe I am riding my clutch a bit??? I have a bad habit of that.

What everyone forgets, is that a hydraulic clutch, with a good mechanical linkage, takes all of the play away from the bearing, even with only slight pedal pressure applied. If there is no really sloppy movement in the linkage, once the pedal is touched, the fork moves ever so slightly and just resting a foot on the pedal can create tension against those pins.

Your fork looks pretty good, so if you want just the pins, I have those also.

If you need anything email me. You have my email address.
