Ok ya'll here is the latestest in my drama. I pulled the left side crankcase cover off. The starter reduction gear a/b are shot. Torn all to hiii. The teeth on the end of the starter are shot as well. The stator is screwed too. The copper wraps are ground down there are metal shaveings in the fly wheel area. The fly wheel spins freely after you kick start it. That is the noise I was hearing. I have ordered the stuff to fix it but have to wonder how it happened? The fly wheel one/way bearing is bent and that don't make much since either. Remeber with all this damage in the this is a running 250 fourtrax that don't smake or knock. Any idea as to what could have caused all the damage inside this thang? It is obvious it has been apart before too.:icon_cussing:

sounds liek the person who put it back together possibly didnt put it back together right

 

[shutto134]

Thank your right. The starter had one screw in it and it was loose. I believe the medal I have found in the thing come from the teeth and all on the starter and the reduction gears coming apart. Anybody out there have any reduction gears they want to part with. I need some.

It's getting hard to find parts for those 250's. I hardly ever see any Fourtrax 250's around where I live anymore. I see plenty of the Fourtrax 300's. They only made the 250's for three years, 1985-1987. They were good 4-wheelers, though. In my opinion, they were just as tough as the 300's.

The 300 starter and gears are set up about the same as the 250, but I don't know if they will interchange or not, but they might.

 

[Fastas]

i still have my old motor but i have no idea where the reduction gears are if they will interchange out with the 300 ill see what i can do

 

[shutto134]

That would be great. If they will change out I'll take them off your hands. See if you can research and i'll do the same also if you have a camera take a couple pictures of them and i'll give you my email address and you can send them to me and i'll look at them.

According to bikebandit the parts are one number off. but I wouldn't be scared to try it.

 

[Fastas]

i pulled up my setup on the left crank case but im not sure which gear you need

 

[shutto134]

behind the little black cover on the left side crank case is one set of gears that are attached to each other. One is smaller than the other. They are the ones closet to the starter

 

[Helmut]

Fastas, he needs part #10 in the diagram below. It's the gear with two gears machined together, a large gear with a small gear on the back of it. In the diagram below, it just shows it as a single gear, but its double. I looked the gear up for both the 300 and 250 and both gears have the same number of teeth.(43T/18T). So, I guessing it will work if it's the same diameter.

Man that 250 case looks like it would fit my 250X!! lol wouldn't that be a nice add-on?

Actually that diagram is for the 300, but the 250 looks the same.

 

[TRX2fiveO]

Either way it still looks like it would fit..lol

 

[Helmut]

Either way it still looks like it would fit..lol

It might work. Wouldn't that be something?

 

[shutto134]

it would be AWESOME!!!!!!!!!!!!!!!! if it would fit. It was bothering me that all the diagrams I see were only showing the one gear. Anyway I have some "vin ranges" that will work. The 350 is with in that range and it you look up those parts they show the same part number.

Either way it still looks like it would fit..lol

No kidding man... an electric start 250X with a back-up kicker...LOL I think I'm going to find me a 300EX left side cover.

Moose, you would also need a magneta/flywheel with the one-way bearing bolted to the back of it, with the starter gear in it. I wonder if it would work on the 250X crank? Also, there's a round, recessed hole in the block that the shaft #7(diagram) fits back in to hold it in place. I wonder if the 250X would have that? Another problem might be if the 250X doesn't have the two mounting holes for the starter bolts.

just make it so dang difficult helmet good lord

I know, but I was just trying to figure out all the problems before he buys a 300EX side cover and then it not work.

 

[Fastas]

i know lol, i found the number 10 gear and the shaft and my old starter is still good off my old bike.
