YTM-225DX twisted swing arm

[Yamada]

So today I went ahead and I started the disassembly of my YTM-225DX. Since I bought it I notice the bike was always leaning on the right. Sometimes I thought the frame was bent, some other time it was the neck of the frame but now I'm 100% positive that it was due to a bent swing arm. Look at the picture, once disassembled it is obvious. I have a spare swing arm I bought 5 years ago, but I just saw that the previous mechanic installed two brass bushing over the swing arm pivot bearing cup. I achieved to remove the bushing but the old conical cup are stilll there. Also while disassembling I saw that the nut holding the driveshaft u-joint was loose. :wondering I'm lucky it didn't became undone before this.

I also have to change the driveshaft oil seal, add some missing o-rings and change all the rear axle bearings and I think I'll have to take the engine apart because the base gasket is leaking oil. This is the first time I'll take the top-end apart on this 3-wheeler. Maybe it will be time for a new piston. I think the original piston is still in. 174358

I dont see too many people with a DX, you happen to have a link to a manual? Im in the process of teardown for a rebuild.

I've read somewhere of some guys putting Timberwolf rear ends on these. You might want to look into something like that.

I already have a good spare swing arm. I removed the old bearing race last night. The chance are that even if I manage to find a timberwolf rear and I would still have to replace all the bearings. I know the timberwolf engine are similar to the 225.

Only the top end of the timberwolf will fit on the dx, they both have a different drive, Fabio on here showed the differences between the engines they say will fit, ill see if I can find the thread for you.

Little video I made during the disassembly. Notice the absence of gas tank, and rear end, but it still run!

I don't saw this post. But I know the top end is very similar. To call it a 250cc Yamaha just installed a first overbore piston. So the bore is bigger than the 225dx.

There's no video?

[the great gazoo]

It says it's "private"

[ColtonGG33]

you have your youtube account set for private you gotta go into to settings? i think and change it to public

[Husky250]

Good info guys!

The video should work now. But it nothing special, just find it funny to have a half disassembled 3 wheeler still in running condition.

yfm 200 moto4 rear swingarm,diff and ale are the same , I swapped a spare ytm setup into a yfm and they r identical and easier to find, a lot of parts interchange on them between the two. just saying for reference. and speaking of manuals for reference I have a Clymer full color manual for the ytm and yfms and figured it might be of some help to others but I dnt know how to upload photos to this site yet.

Use a site like photobucket. Upload it to there. Copy the code they give you (Will be for forums and start with [IMG]). Post the code here and there you have it. You can upload to photobucket from mobile devices which i like, and you can edit pictures there.

OR, you could post a reply, like i am doing now and look at all the options on the top of the box your typing in, click on the square picture thing 3 over from the right. Hover over it and it will say image. That will upload your image as an attachment.

What swing arms fit the 86 ytm 225drs?I'm having a hard time finding..dealer says only 85 and 86 drs are a match?

I think that you can use the one from a DX, but you'll have to use the whole set up. You may have to use the DX rear end too.

check a site like Ereplacement parts dot com... some of the sites lie that show which parts fit other models.

So does a timberwolf axle fit in a 225 rear end. I need a new shaft

No the timberwolf axle is completly different because of the brake design. But you can use the complete timberwolf swingarm brake axle wheel etc.
