Torque converter pullys won't align

[itsid]

IIRC Grant uses graphite lubricants on his TCs as well..
I don't see no harm
(yes it's dark and may look dirty... but since that's the inside of the bell... who cares)

I bought some dry lube that is clear, dont know what base it is, and I didn't see those scratches till after I used this stuff, mybe coincidental idk.

 

[Kleyny]

Yeah I just bought some that is also clear.
I just made sure it's good for a decent amount of heat.
500f should be enough.

I think I realized why I have bad gearing even though everything is stock except the TAV2...this thing used to be on it

Lol yep that'll do it

So does anyone see any problems with how this would work, or have any comments or concerns with this diagram of how I plan on reversing my sprocket setup.

P.s I know not an artist

P.p.s i also know my chain needs better alignment than in drawing haha

P.p.p.s I will probably use wider bushings for where I need a lot of washers, and those will be lock collars where it says lockrings

any shaft always needs TWO bearings...
not one wide one.. sooooo TWO pillow blocks!
And as close to the applied force as possible (i.e. as close to either sprocket as you could)

that free dangling shaft section will deflect under load!

Will the bearings in the backplate of the tav2 not act as a one set of bearings and are you referring to the free dangling shaft in between the backplate and the pillow block deflecting?

 

[itsid]

NOPE!
your front wheel has two bearings since it rides on one shaft -the spindle;
your axle has two bearings since it is a rotating shaft, the crankshaft in your engine has two bearings... etc. pp.
Dang even the wheels in your rollerblades , kickboard or skateboard carry two bearings each!

two bearings PER shaft minimum.. ALWAYS!
and a chain is in fact what's deflecting your shaft, the bearing is there to PREVENT that from happening,
so no, the TC bearings (holding the TCs jackshaft in place) will NOT help.

PS Sorry, that sounds rude.. more rude than intended,
but you asked if you can use a tennis rack instead of a set of wings on your plane

 

[Shambosley]

Ok I appreciate the helpful critisism indeed. So your saying my shaft should go through the 2 TC bearings, then through 1 pillow block bearing, and then through another pillow block bearing, is that correct? something like this?

 

[itsid]

exactly!

But may I ask Why don't you reuse your old one?

You can then just install a new shaft to it
(longer so that you can move one sprocket to the other side)
maybe one sprocket (maybe both, maybe not even one) some washers and locknuts.

chances are it'll fit on your kart just perfectly
(considering it had it mounted when it left the factory )
and all you need to care about is to line the sprockets up again.
No need to buy or mount pillowblocks

I planned on using my old one until you said I needed 2 pillow blocks, so I ordered 2 pillow blocks that way they are both the same since I will have to shim them in order for them to be horizontal will the back plates shaft slot. And I'm not sure what you mean in quote, using 2 sprockets or my be not even one?

 

[itsid]

I meant what you had is
two sprockets, two bearings and a mount that will fit onto your chassis in good orientation and alignment.

so in theory a longer shaft (some washers and nuts) might suffice.

that is, if the two sprockets on there can be split from one another and are not one single piece,
in which case you might need to buy at least one new sprocket... and depending on the position of the sprocket in worst case two new sprockets.
(but most likely not even one, but are able to reuse the ones you have)

[Shambosley]

Still not quite sure what you mean, I am new to go karts and basically anything with sprockets hence the reason I started this post. I do better with visual learning lol I'm just gonna try setting it up according to the sketch, if I have problems I'll let you know. Thanks for hanging in there with me sid, it is more appreciated than you know.

Hey.. we're all here to help,
and sometimes we're the grumpy old men your mother warned you about,
but we not ONLY scare you off our lawn,
we also try to give you a hand when and where you need it.

So no worries... we will talk you through whichever hurdles appear

Now: what I meant is basically "replace from orange pillow block to orange pillow block [both pillow blocks included"
with the jackshaft you have
the thing you posted earlier.. remove the jackshaft
to do so:
remove the C-clip on the "no sprockets" side and you can easily just install a longer jackshaft than the one that's in there if needed

Frankly I think you can just pull the jackshaft ot, remove the smaller Sprocket, reinstall the
jackshaft to the jackshaft retainer, the put on the smaller sprocket again (to the now sticking out jackshaft and reinstall the C-clip to hold it all in place.

the length should still match perfectly, if the distance between the sprockets is not matching your needs,
you need a new (longer jackshaft.

What you DO NOT NEED is pillow blocks (not one not two.. none!)
since that jackshaft retainer is better than mounting two pillow blocks for more than one reason. (best reason: alignment!)

Ahh I understand, but the shaft that runs through my stock jackshaft has 2 sprockets on it that are welded to the shaft. I have already ordered a new longer shaft, lock collars, and 2 pillow blocks. I have a 55t axle sprocket. I was wanting to just use my original jackshaft but revmove those sprockets and shaft and run my longer shaft through and mount the clutch sprocket to that shaft on the oposite side, as shown in my first sketch with one pillow block(my shaft holder)

 

[itsid]

I'm fairly certain they're NOT welded on
(noone welds sprockets to a shaft other than a complete moron... kart manufacturers certainly don't!)

chances are it's welded to a short hub section and that hub is just keyed to the shaft
(as how decent people attach sprockets to a shaft )

STILL, although you already ordered the pillow blocks (wrong move imho.. nevermind)
you should reuse the one you have, (and just send back/sell the pillow blocks)
well that is if you ordered shaft is the correct size, chances are it's not tbh...

Ah well... tough luck, right

Anywhoo, be sure to align the pillow blocks perfectly parallel to each other and the shaft they'll carry perfectly parallel to the axle!
otherwise the chain and sprockets will bind and chew away on each other..
that's not only noisy, it's also drawing power and reducing the lifespan of the chain and sprockets.

that all is basically done for you already if you'd instead used the one you had....
that'S the reason it'd still be my first choice even if you ordered parts already!

'sid

PS yeah... no, just more work for you, if done correctly, no matter what it'll work fine in the end.

 

[KartFab]

Should the inside of by drive pully look like this lmao... another indicator of bad gearing? I got the new sprocket but cant put it on because the rod that holds my brake band on is right in front of it barely with enough room for the 36 tooth sprocket that's on it....

i know this has already been answered but yes that is supposed to look like that and the 'dirty' looking spots are exactly where the lubrication needs to go (that and the splined hub).

Dry graphite is good
dry moly is great

anything else will wear off quickly or gunk it up

 

[Shambosley]

Yeah its been work for sure. Either way I do it, ive got a bit of fabrication to do... My axle keyway doesnt go far enough for me to mount my sprocket as close to the motor as possible, So... I guess I will have to dremel the slot longer. I have a support bar that wont allow my new bigger sprocket sufficient room that needs to be cut off and welded somewhere else... I have to make a mount for the pillow block to run horizontal with the backplates shaft hole the drill new holes for it all to align parallel. I swear its been one thing after another. Y'all have got me a long way, at least knowledge wide if nothing else. Who knew I would have so much trouble adding a bigger sprocket just to have a better gear ratio, but y'all have shown me the importance of having a decent ratio!!

Ps the original jackshaft does have welded on sprockets

 

[itsid]

you see me baffled...
man we really need pics of your kart!
I cannot recall any mfg doing something stupid like that...
sprockets are to be changed regularly (ideally with the chain ) so their life expectancy is maybe a year or two, the shaft holds the lifetime of a go kart..

It's like "welding tires to a rim"... that stupid.

Anyways, true true.. you'll need to swap the axle and both sprockets (obviously)
