Comet TAV 2 advice needed

[Doug L.]

Hi, I have a TAV2 mounted to my yerf dog 3203 with a 6.5 Lifan engine.

Yesterday,I drove it full throttle (bout 32 mph) 6 miles, took a break, then drive 6 miles back non stop. Just before making it home, I burned up my belt. No biggie.

Everything was well lubed before leaving. So, my question is I noticed that my driven pulley's rear plate has some very slight movement (that I didn't notice before) where the three rivets are located. Did driving it like I did cause this and should I be concerned? Would it hurt to tack weld the rear plate to the rivet plate? Also, I noticed that one of my jackshaft's bearing kinda grinds (not excessively). Replace it? Both?

Thanks
Doug

Bearing

 

[itsid]

well between the sprocket and the bearing there should be a small washer to prevent the sprocket touching the outer race.
if that's lost... it'll grind;
and that isn't a good thing (in the end it'll render the bearing useless as a result)
if the bearing itself is clogged.. get a new one. (sooner or later it'll fail)

And with the easy one out of the way..
the backplate..
you haven't lubed it.. please tell me you havent...
there is absolutely NO LUBE on the driven
and only a small amount of drylube inside the driver where the weights meet the shell.

anything else can make the belt slip.. and the result will be a burned belt (coincidence?? I'm afraid not )

Maybe it's best to try to tighten down the rivets before tack welding the sheave..
in any case make sure you do not deform the sheave, neither by force nor heat.

Get a big c clamp and 2 pieces of flat steel. Clamp it together all the way. Then use a pointed center punch to expand the rivet outward. Don't go crazy and break them..... That would be a whole 'nother can of worms......

Hi sid, I will replace the bearing. And yes, there was a small washer (in which was included in the kit when I purchased it 1 1/2 yrs ago) between the sprocket and bearing.

Ok, when I "lubed" the driven, I used the proper COMET dry lube on the surfaces pictured. Am I doing this right?

As for the belt, it didn't really burn up as much as it shredded.

Just for kicks

Thanks sid!

Hi Jim, good idea! Could I also use a bench vice too?

Thanks!
