How do you change the forks on a yamaha pw50?

occert · 03-04-2007, 03:50 PM

I need to get the inner tube out of the fork assembly on a yamaha pw50 (2005). I know there is a snap ring at the top, and got that out as well as other the metal slide, collar, and spring rebound, but can't get anything else out. this is the left fork if that makes any difference. Any suggestions would be appriciated.

Are they bent, or are you replacing the seals.

well, first of all i want to let you kno i moved this post to our suspension forum. hopefully our suspension expert will be able to help you out. well i kno this sounds broken but your gonna want to take the inner tube and the outer tube and jerk them apart hard until you end up pulling out the oil seal and the inner bushing. make sure you have the clip out first, the one behind the dust seal. if yur sure u have it out then pull them apart. i know it sounds broken but it is the truth. just to review, you popped the dust seal off, removed the clip resting on top of the oil seal. then you also opened them up and unscrewed the cap from the inner rod. nothing else should have to come off. granted i have never worked on a pw50 but all the other forks i have done work that way.

Hmmmm, it's been a long time since I took one of those apart and I can't remember if I ever succeeded doing it. I think that the honda XR/CRF50's are the same so if anyone has any experience with those it will probably transfer over to the PW50. I'll see what I can dig up but I would try to find a manual or possibly a breakdown of the parts within the forks. I'll try to find that and then post.
Sorry I couldn't be of more help!

heres the front fork diagram for a 2005 pw50, came straight from yamaha.

The fork is bent near the middle of the inner tube. I got it out (with the help of my truck and chains, hehe) but I am not sure if that particular fork is meant to be disassembled all the way. The diagram from yamaha shows the left fork disassembled and gives an OEM price of the entire right fork. I know I said it was the left fork but according to the diagram, it is the right. (I guess it depends on what direction you look at it.) Anyway, I was wanting a machine shop to straighten it or save some money and just buy the inner tube. Now I might have to buy the whole fork anyway. Thanks for all the help. Any other suggestions now would still be helpful. Anyone know where I can buy the fork for cheap, or even a used one? I am just trying to fix the bike up to sale it. Thanks.

ahhh that makes me smile. using excessive force is the best way to go. but you can get it straightened really cheap by a machine shop, it works because my friend and i kno a guy who has his own shop and it took the press to my friends steering stem on his quad and it was straight in no time. or check out ebay for a fork.
