Issue with chain rubbing torque converter

[Ryanhodge2715]

So I bought these two used trail master mid xrx first time stepping into any small engine projects at all. Learning a lot quickly mostly what not to do lol. But one of my carts have no issue but this one something must have been changed after the fact to cause this. But looking at my picture the torque converter does appear to be bent down wards causing it to kick over to the right a little, a then my sprocket/rotor looks to be about 1/4 to far to the left. I know this because you can kinda see it just looking an also the bolt heads that actually hold the rotor on have made about 1/4 grove into the frame that is holding brake caliper. Makes me wonder is the bracket that holds my sprocket an rotor adjustable to slide? Or should I consider just putting a washer on left of the sprocket to get the chain away. That would fix my grinding nose from chain but still can’t be right with the way those bolt heads have eat a grove like they have. Please help fellas bought it for my boy for Christmas not running the wife was dead set against it. But I told her I could figure it out! ‍ help a fellow brotha out

I even considered just putting washer on the back side of my pulley but the rotor is in the was of the pulley sliding off. They are the same models but I think the guy did after market stuff because this rotor an sprocket are definitely bigger then the other cart

 

[Ryanhodge2715]

Also another thing I was curious about is the chain on my good one I can pull on it an it has a little movement but the chain on this black one is solid super tight compared to other one. Not possible it’s to tight a maybe Bent shaft some?

 

[Master Hack]

Major misalignment! The chain should be straight. The fact that is that tight indicates another problem. Look at the "other" one and figger out what is different.

 

[Ryanhodge2715]

Right so how should I go about alignment? Is the base the sprocket is mounted to adjustable? An yeah this one looks to be like 80 tooth other cart is half that. The rotor is almost double size too. But what would make chain over tighten? Aren’t those cut to fit?

 

[Master Hack]

Hard to say with just those pics. Looks like whoever worked on it shouldnt have.
You're gonna have to move things around. That could mean cutting, moving, drilling, welding, fabbing, and/or all the above. Chains get screwed up like that when someone changes something and doesnt know or care how to do things right.

 

[Ryanhodge2715]

Thanks for the reply’s man.
but to others totally still open to any advice. Still at square one

 

[Master Hack]

I know thats not what you want to hear. I really cant see where the problem might be.
the area looks crowded, and changes have been made. Maybe some more detailed pics?

stand by, one of the guys smater than me will chime in here soon!

 

[Ryanhodge2715]

Yeahh I understand… comparing the two all is identical except sprocket an rotor size. It’s the original axel so thinking they just bolted on no big changes really. What I’m wondering is it possible a wreck or just wear could have allowed the axel to move over that 1/4 of an inch it appears it moved. Basically wondering is that axel itself something that can be moved in our out. Or possibly that base my sprocket is attached to it looks to be just sittin on the axel an could be movable but all I see is 4 bolts on rotor side an 4 holding the sprocket on.. nothing else tho

 

[Ryanhodge2715]

I haven’t actually took a swing an pulled tires an chain off to see how it actually works. When putting the axel on is it something you adjust where you want by hand a tighten in place or is it like a preset position it locks in to place? Does that make since?

 

[Ryanhodge2715]

That bolt head I circled clears that medal by half inch on my good one . Not sure that pic any better but it is to the left to far An with the sprocket need to go to the right as well it looks to me like hole thing needs to move over.. but my tires are already close to the frame so that why I was wondering if sprocket is adjustable

 

[Ryanhodge2715]

Man I tell ya I’m thankful I found something like this glad there’s good people just willing to help each other figure stuff out. when you don’t have no one to call on an ask dad questions it’s discouraging trying to blindly figure out

 

[Master Hack]

Well, you came to the right place!
We are the blind leading the blind!

Chains aren't cut to fit. They have a master link, and with a simple chain breaker tool can be lengthened or shortened at will. From the pictures you posted it looks like your axle sprocket has moved to the left. The HUB ( the thing that the sprocket is bolted to, that rides on the axle ) should be able to be loosened and moved back over to the right. I am very surprised that you can't see this. To me the torque converter looks fine. You have a bad misalignment between the drive and axle sprocket. You told your wife you could fix them. Well, it's time to do like Master Hack told you. Break out the tools and keep the wife from proving you a liar. Really this shouldn't be that hard of a fix. The fact that you have another one to look at should make it easier.

Also in pictures # 2 & 3 on the outside of your driven clutch is a large lock nut
( as there should be ) in picture # 1 and again in post # 11 the nut isn't there. With out it the clutch will walk all over the place. What's going on with that, or am I looking at pictures of different things.

 

[Ryanhodge2715]

I get that an I have looked brother no other bolts other that what holds the sprocket and rotor they are one conjoined piece an looking by break caliber is mounted in place so I don’t know that it will allow me to shift as far as I need even if I could loosen the hub. An yes I took my spring off an was going to pull the driven pulley off an just use a washer to get by. But with the rotor being larger on this cart it blocks me from doing so.

 

[Ryanhodge2715]

Gonna pull tires off an actually dig in tomorrow just hear for whatever advice I could find if I can’t adjust was kinda thinking maybe pull sprocket off an out a washer or two to space it out.

 

[Master Hack]

Dude! You can absoutely not ever even think of letting the wife see a failure such as tthis! Do you even realise how much crow you gonna be eatin? Get in there and fix it!
the entire male gender is counting you! Do not let us down!

 

[panchothedog]

You can add or delete washers and spacers to improve alignment. Just make sure it's not causing another problem. And yes the future of ALL Mankind is riding on your ability to get this right.

It honestly looks like the entire axle is moved over, which would add tension to the chain up to the point where the chain derails itself UNLESS it was put together like that and over tightened to the point its unable to derail which would also be wrecking the chain, sprocket teeth, and bearings.

Idk if the carrier hub on that for the sprocket and rotor moves, but if it's been apart there's a high probability some spacers got lost or added incorrectly at the wheel hubs or wherever the axle bearings are holding the thing in place. With any luck there is some sort of lock collar set on the axle that you could loosen and adjust the axle with a swift kick to a tire.

What I would recommend is measuring the width of the rear from inside rim lip to lip, divide by 2 and see if that meets in the middle.

To explain better what I mean more concisely; Let's assume a 36"axle, and you get 30" between rim lips. IF the axle is correctly centered under the machine than 15" from the left and 15" from the right would both lead to being able to make a mark on center of the swingarm subframe (silver sharpie is great for this)
If the axle is badly off centered you would be able to see it in the mark position, but you would still be able to measure the suffrage rail to rail and say "okay the whole axle is definitely 1" too far left".

You need a new chain after you correct it, between the tension, angle, rust, and general strain I wouldn't trust it to not be the next problem.
