u need to replace the shaft with this one... to fit a stock honda crf50f eBay Motors: Steering Column pitbike XR50 XR 50 70 CRF CRF50 SDG 8.5 (item 150155671887 end time Mar-19-09 15:45:47 PDT)



... what you have is the Pitbike Size... for longer Chinese head toobs... so ya... make sure to mesure the stearing stem that you have and see if the replacement one will fit..





>>i can asure you that if its a fast-ace tripple set... that shaft will fit... ive used it on mine and it worked... but double check with a digital caliper and compare it to the sizes he has shown in the listing.... to do this you will have to press the shaft out of the set you have... and if it is comperable to the replacement one i showed you... have that one pressed back into it.



good luck.

 

The Stem that's in the clamp now is threaded into the bottom clamp. It's not pressed in.

 

I don't think those are the FastAce tripples you have there. I have a brand new set of FastAce 02's sitting here and the tripple clamp and stem look nothing like yours. Also, the FastAce stem is alloy and yours is steel. That might explain why you have a different type of stem.



If it were me, I would put it together on the frame and if the bearings are fitting up correctly and your left with a stem sticking up a little too high, cut it down. Just make sure the threads still go down low enough for the cap nut to tighten down to the top clamp, if they don't (by say a 1/4" or less) You can always put some washers under the cap bolt to take the space.

 

I'll post up a picture of the triple clamp.

The stem is too long and the threads aren't far enough down to tighten the nut good enough.

 

Here's the clamp:

 

The bottom clamp doesn't seem to match the top clamp's finish.

 

From what I can tell, this looks to be what I have in front of me:

You do not have FASTACE clamps. FASTACE clamps are black. The top clamp you have is similar to Pitster/GPX clamp the bottom IDK. That top clamp is exactly like the one I got from TDR. You could see if you can find some real FASTACE clamps or take you stem to a machine shop and have them turn down the top bearing area to where you require it and also thread it a little lower too and then cut it shorter if need be. I would make sure that those clamps actually fit your fork tubes first tho....mock it up on the bike w/o bearings maybe.....FASTACE use 48mm clamps upper and lower

The clamps fit the tubes, but the stem is too long. Where can I get a set of FastAce clamps? I've seen the entire setup with tubes, but not just the clamps.

 

You could also just cut and add a spacer above your top bearing if the bearings seat into your fifty neck ok.....then add your spaner nut and top clamp.

maybe too ghetto but will get you rolling until you have the stem turned threads cut and shortend.

 

I had thought about adding a spacer to the bottom to bring the threads lower into the steering tube so the nut would tighten up more.

 

I would add it above the top bearing just before the spaner nut. Does your bearings fully seat into the neck when mocked up on the stem?

 

Ok. I've put the spacer above the top bearing. I'm going to see how it works out now. brb.

 

take a picture of your setup mocked up and post it before you tighten anything up.

 

 

so did you just add washers? both top and bottom bearing are seated in their races? If so you should be able to add the top clamp.

 

Only added a spacer at the top. The only problem I have now is the nut on top of the top clamp. It is a cap nut. I need one like the stock clamp has. I need to go to the dealer to pick one up. It would be easier to get another nut than cut the threads off.

add washers before the cap nut as needed...until you can get it cut....well I guess it depends how many threads are left......but you understand.

 

I don't have that many washers. lol. I'll see how much the nut is.

 

There's 22mm of threads above the top clamp.



edit: Dealer doesn't have any in stock. They are $2.38. Won't be able to get it until next Tuesday.

 

The tree is free of up and down and front to back play but still turns side to side smoothly...? If so you are good...like I first said..kinda ghetto way. but will work...just besure to check the spaner nut after your first ride. also tighten the top clamp on the tree before you tighten the top fork clamp.

if you have a bench grinder just grind the cap off... I need you to sign a waiver that if any happens I am not at fault........8)

 

Got it. Thanks for the help. The tree is free of up and down movement and moves smoothly.
