TAV-2 Question...

[chris insull]

The 6.75 HP Intek I just bought has a 2.250" (3/4" dia) length shaft. Is this long enough to mount the TAV-2 and sprocket?

That will work as long as the intec has the tapped holes to mount the tav on the side cover.

[chris insull]

Thanks. It's got four tapped holes adjacent to the shaft.

It will work just fine! Like Woodchuck said.

[chris insull]

I received my TAV-2 yesterday without instructions. Looks very simple... The only questions I have are:
1. what are the bolt torques (all five)?
2. where are the spacers (two) used?
If anyone has a set of instructions they could e-mail/ pm, it would be great!! TIA!!

[moto1fast]

I just tighten the bolts to about 15 foot pounds and use locktite (blue) on the threads. The spacers one should be 3/4 ID. that goes behind the front clutch assy. on the crankshaft, first to go on! To get the right length of that spacer put the belt on ( with the tapered side of belt to the outside. Flat side to the inside.) put on the front clutch assy on crankshaft, line up pulley so that belt is striaght. measure your distance from inside pulley to crank shaft bearing. It should be around 3/4" to 7/8" long. Check to make sure that your tav housing clears oil fill plug. Sometimes you have to grind a little off the inside of mounting plate to clear it! CAUTION!! Do that first before tightening up your five mounting bolts or you could break mounting bracket on TAV. The second spacer is a bronze or brass bushing that goes inbetween the inner plate and outer clutch assy, on crankshaft. The belt will ride on it instead of on the crankshaft. The spacers are shown on the link below are # 11 and # 8.Here is a link to show its parts and where they go! Also a good place to get part #'s of replacement parts.http://www.mfgsupply.com/GoMiniClutchTorqTAV2parts.html/mv_session_id=qXnRi5KW Hope that helped and if you need a pick let me know and will post one.:cheers:

[chris insull]

Thanks for the help! I installed as in the diagrams you had a link to, so I should be ok. There doesn't seem to be alot of crankshaft engagement for the front clutch assy, however...

[moto1fast]

What do you mean " a lot of crankshaft engagement for front clutch assy"? The clutch when it engages at higher RPM's goes in towards the back plate and makes the belt tighten up. It should not be tight at idle or shut off. It will be loose then! The outer clutch (front) only will travel about a 1 1/2 inches in! If you installed it by diagrams you probably are ok! It does not travel near as much as one on a fourwheeler. Post some pics of your setup!:thumb:

What I meant was engagement for the crankshaft to the front clutch spline when bolted down. (the amount the clutch slides over the crankshaft)

[moto1fast]

Ok, There is not very much clutch engagement about 1 to 1/12" it slides over crankshaft! This would be normal. But if it only moved about 1/2" or less you would have a problem!

I emailed Comet for a owners manual because I did not get one with the unit. They sent me a PDF the next day. A little hard to get to from the website. Drop me an email and I can send you a copy of the PDF I got if you have trouble getting to the "customer service" area.
I am pretty sure its to big to attach here.

I'm looking at the same "issue" that Chris is talking about.
I got my TAV today, and of course I've already mounted it to my Sterling 6.5. And here is what I found. Yes, I had to grind down one of the supports on the back of the rear pully shaft support. It was hitting on the second oil fill port, if that wasn't there it would have fit like a Glove. Click on your link to the TAV parts list, look at part #5, that "Hub Driver" Part. Well, it only slides onto my crankshaft about 3/4 inch. Is that enough?
Will that be too much force on that end of that part, since half of it is hanging off the shaft?
I'm sure you know exactly what I'm talking about, What do you Think?:dizzy:

Gadget,
I followed what Moto said above and it works fine. I testfired the enging and TAV on the frame this past weekend to check my clearances, etc... with no problems! I also Rechecked torque on all bolts after about 20 minutes of operating and all was well. The only thing I may do on final assy will be to add some blue threadlocker. HTH.

[CritterBuddy]

I did some quick checking and found that the exposed Sterling crankshaft end is 2-1/4" long. A standard Briggs & Stratton is 2-27/64". This means the Sterling is 11/64" shorter than the B&S. If you have trouble working with the 64th measurement (I sure do), the difference is just under 3/16" which I would think wouldn't be enough to worry about.

[Gadget Man]

CritterBuddy:

I'm still a bit leary,
That drive hub is less than half way onto the shaft.
I know the bolt is holding it from ever coming off.
But I'm wondering about the stress that the Drive Hub will be under when I hit the gas.
I'd like someone to tell me they had the same situation and everything worked out just dandy, then I'll drop the subject and move on to the next "issue"

I did a test fit on my Harbor Freight 6.5 Honda clone motor and TAV30 with the same concerns. Is seem to me the clutch hangs over the end of the shaft by 3/4", with less than 3/4" contact with the shaft.
Anybody got a solution to this?

[moto1fast]

I understand the outer clutch does not go on the shaft very far! I have used these a lot and never had a problem. If you think about it it will make sense why it does not have a problem with this being the way it is. Remember that as the RPMs increase the clutch slides in on the shaft so when force is being put on the shaft the clutch is over on the shaft more. At idle there is no force or pressure on the clutch or crankshaft! I have never had a Crankshaft bust on these yet! LOL The only time I have seen the crank busted on one is when it got a hit on it by a solid object! The outer clutch goes on far enough about 3/4 inch and have not had one strip the keyway out of crank yet either. I have not heard anyone else have a problem yet with this issue! So I would say you wont either! Just remember to check the tightness of the retaining bolt every once inawhile!! USE LOCKTITE on your threads to help also with this!:cheers:

[Gadget Man]

Moto,
Thank You for your reply...:thumb:
But what took you so long, I haven't slept for days....:dizzy:
No realy, this is exactly what myself and at least 3 other guys have been waiting to hear.
Your thoughts on the clutch sliding on the shaft makes perfect sense to me. There will never be a lot of force/pressure way out at the end of the shaft. But it sure had me thinking for a few days there.
Thanks Again, You are the MAN!!!

Now, I must move on to the next crissis in my life.

Gadget Man :cheers:

[Frozen Bohemian]

Thanks for the info. I was able to confirm with Comet Industries that the drive portion of the clutch only needs 3/8" engagement with the engine shaft for proper operation. So basiscly a 2 1/4" sahft works just fine.

BUT here is another question

I wanted to paint the black metal portions of the clutch to match the motor. Do the clutch covers get hot enough to burn regular paint?
Should I stick with a high temp paint?
I did paint a centifugal clutch drum on my old stool, and the paint quicky burned off. Nasty deal.

[Gadget Man]

Frozen Bohemian:
Thanks for making the call to Comet Industries,
I guess we can't get any better answer than "Straight from the Horse's Mouth"
And, ya-know, I just looked over at your Post Count and saw that you are from Minnesota, Hey, how about that -22 degree weather, aint that Cool !!! (ever do the bubble blowing thing outside at -20 ?)
These other guys are all jelouse.
Where abouts in MN are ya from ?

Gadget :cheers:

[moto1fast]

You can paint the outside plate with regular paint! It does not heat up like the centrifical clutch housing due to a lot lease friction!:cheers:
