engine mounting help please!

[v1deoguy]

Hi. I'm new here and to go cart building. So I bought a Carter bros go cart, or what was left of it, off Craigslist. Everything was there basically except the motor. So I was given a Honda gx240 8 hp motor for free. I go to mount it and the current mount sets the engine way to far to the left. Its a torque converter (pulley system) that connects to a jackshaft that connects to a chain connects to the axle. Hope that wasn't confusing. I'm guessing I need some sort of adapter plate, system etc to mount the motor to the existing mounting plate that allows for the motor to slide more to the right so the drive shaft lines up with the driven pulley. I added a pic of the mounting area. This is a project for me and my 12 yr old so any insight into what I need to do to get this running is greatly appreciated, thanks!

If the engine fits the holes in the current plate... it looks like you can slide the shaft(not the mount) of the JShaft to the left about an inch or more.

A.- Disassemble the JShaft and leave that lock washer (behind the chain gear)outta the equation along w/ anything that looks like its being used as a spacer.
B.- Flip the gear around, so as that the teeth are the closest to the end against the locking end bolt.
C.- Upon reassembly of the chain side, slide Shaft all the way to the left... mount engine and Driver to engine.
D.- Align pulley's and shim/space the "Driven" accordingly on the shaft.

There should be lil-no slop (left/right) movement.

You may wanna also add a drop of locktite 'red' to the treads of the end/retaining bolts... they can have a tendency to unscrew themselves at times.

Youre gonna wanna do maintenance on the TC from the looks of things (or youll be eating belts and their not exactly 'cheap').

Thank you for the idea. I understand what your suggesting but it looks like ill need more than the inch or so that moving the jshaft will provide. I'll need about an additional inch. Also I purchased a torque conversion kit so new belt, driven, driver etc is on the way. The motor has a one inch drive shaft. So question is, how do I gain that additional inch needed after I move the jshaft over to the left. This maybe a dumb question but does the drive and driven have to align exactly?

 

[chancer]

Yes they have to align exactly.
You could cut that mount off and move it over. Or get the Gx200 or Predator 212 motor.
They should just drop right in.

Is it just me? ....or is.....

From the pic... it looks like you have plenty of room to slide the JS housing to the left n drill new holes to bolt to...

Well 1" engine shafts arnt my preference of engine... meaning the 40 series TC you ordered (only guessing its a 40 series... if not... HOPE its not a 30 series or a TAV2 >.<)... any "experienced" user (Kartfab) will probably be a better choice for answers... but... from what Im understanding on the 40 series is, it depends on how your gonna run the 'driven'. Yes, they have to be aligned, but alignment of the stationary sheave vs center to center is what Im unsure of... Id rather NOT give info that I havnt personally had my own personal trial n error experiences w/.

My bad! I guess it's my little phone or something....but it's hard to make out the engine or torque converter and how everything lines up in that pic????

Plz dont direct your arrogant replies towards me... not like you could effectively help anyways!

 

[v1deoguy]

Thanks for the responses. The description of what I ordered is " 1" replaces comet tav2 manco 10T 40-41 and 12T 35 chain drive belt. 1" 10T 40/41 and 12T 35 chain. Thats exactly what the description on Amazon says. New to this but it sounded like it was the right kit to buy. &#55357;&#56851;...The Honda 240x was free so it was hard to pass up.

well the TC you ordered is incompatible I'm afraid!
see how the driven is installed on your jackshaft?!
(that's a Comet series 20 btw)

The series 30 is asymmetrical and cannot be mounted this way around.

you either need a series 40 (much easier to get, but may not fit because it's also slightly wider)
or indeed buy a series 20 driver unit (the driven you have can be restored)


And sorry Tihm, Doug's right.
I smell something fishy in here.. we MUST HAVE a pic of the engine PTO side..

the GX240 isn't wider than the GX200, not by two inches!
That engine plate is ready for a drop in replacement of any 5-8hp briggs, Honda or clone...
since that looks very very very likely to be a Carter model : 2766.
the engine mount plate may have been relocated on the engine mount bar, but I almost doubt it.
if so, the correct way of fixing it, is cut and reweld said plate......

Anyways, two inches... that engine has a reduction kit fittet... I guess
that's why indeed...

Oh wait, you installed the series 30 driven unit on the jackshaft outboard (as it needs to be?)
that'd explain at least one and a bit inches of misalignment.. but it's not the engine's fault;
it's the wrong TC ...

You're gonna have problems... connect back w/ us after u get the TC ;-)

 

[itsid]

So luckily another member had this kart..
for your convenience:

this is what it should look like:

pics taken from this thread

As you can see, the engine fits in just nicely (that still is a series20 TC)

Now you have something to compare it to...
just take two similar pics, and because of your issue, another from the back (with the driven unit dead center)

[v1deoguy]

Hmmm...here are some more pics. The driven that on it was what it came with. I believe the kit has drive, driven, belt, covers etc..

 

[v1deoguy]

Should mention thats as far to the left as the motor will go. As the oil fill hits that driven unit. Also in order to move the motor back far enough to align with the mounting holes I have to remove-reconfigure the role cage bar. So would the series 40 driven be set more to the right?...

 

[v1deoguy]

A few more pics. The new TC wont be here until Friday but for reference I left the old driven on.

 

[itsid]

well it needs to move right, not left

Anyways, with paitng all over the bearings of the axle and the driven unit the nuts and bolts and whatnot....

well you qualified for a complete rebuild of absolutely everything already.
that was a very bad move!

Yepp that's indeed an extremely long shaft on your engine, and seeing it's not fully keyed that also is the reason for it not fitting properly.

Sorry, but with all the additional problems you just caused I don't think you're going to be riding it any time soon so you can just order a new crankshaft (the shorter one) for your engine, or buy a predator for about the same money but less DIY..
Oh and you'll likely need a new driven now (if you cannot remove the paint from the sheaves the spring and rubber grommets and such)
Boy, that was a really stupid idea!

'sid

 

[v1deoguy]

Ouch!! That sucks, maybe not so stupid but over rambunctious. Rookie mistake. Well a new driven is on the way anyhow. But thanks for the honesty and insight...

Also, Google was no help. Were can I get a shorter crankshaft fo my Honda gx240?..im going to look into that before I Graigslist the motor

 

[itsid]

Sorry pal, no it's not.. you ordered a TAV2 (at least you said so)
And as I said earlier
that's unfortunately not the correct one since you cannot mount it inboard (cam of the driven pointing towards the engine)

you will have to either get a series 20, or a series 40 TC NOT the series 30 you ordered I'm afraid

gx240 Q crankshaft (88.5 mm long 72.2mm for the driver to mount on... dang.. still about an inch longer than a gx200 shaft)
so do me a favour and measure yours first, maybe I was just halluzinating and it's indeed the correct shaft already.

if all else fails, you need to relocate the engine mounting plate on the engine mounting bar
(so that you can still reach the bolt that fixes the bar to the chassis of course )
or custom make a new jackshaft just extending the inner shaft by two inches will only work for a couple of hours befor it bends... so a custom tube will have to be made as well

And back to square one.. it'll be easier and cheaper to just get a predator for 129 bucks (99 with coupon every now and then)

[v1deoguy]

Oh poop!!! Well hopefully amazon has a good return policy. My neighbor welds so ill try to relocate the mounting plate. Get the correct TC. If that fails then ill order that predator motor. Already posted the motor on CL as that could fund the nee motor and TC

 

[v1deoguy]

So what do I do or can I do to convert the driven from an outboard to an inboard mount?
