TAV help

[JRW]

I looking for a tav for my blazer mini bike. Im gonna run a gx160 with 3/4” Keyed shaft but my driven jack shaft is also 3/4”.

All of the tav I come across are 3/4” driver and 5/8” driven. Do I need to go to a 40 series and try and bush up my motor shaft to 1”?

Thanks
JW

If I am looking at the correct Blazer, it is a Tote Gote-type bike, and you are talking about a driven jack shaft, using a driver and a driven, and not a TAV. So the information below is for a driver and a driven 40 series which both fit on 3/4" shafts, and not a TAV with a plate and integral jack shaft:

The 40 series is available in 3/4" both driver and driven. They use a 7/8" belt. The driver is a 44SS, (209709A) and the driven is either a 40 (209133A) or 44 (209621A) depending on the diameter of the pulley, 7.5 and 8.5 respectively.

Yes this is a tote goat style bike.

This is what came on the bike when I got it. With a centrifugal clutch on the motor and it didn’t work very well. I’m assuming that v belt pulley is not correct.

Thank you for the help

No, that doesn't look right. I've restored a couple of Tote Gotes, not a Blazer. I think the 40 series drive is the way to go for you. [MENTION=7282]Richard Trotter[/MENTION] has a trove of information the Gotes, and some knowledge of the Blazer. The Blazers were originally built by former Tote Gote employees I believe.

In the last days of Blazer, they had some of the machines made in Japan. These were the Trail Blazers. They can be identified by the split rim front wheel with drum brake. "Japan" is stamped on the bottom of the lower fork mount, just above the front wheel. The wheel bearings and front brake were better than what tote gote was using. The Briggs motor started model production in 1958 and was rated 5 3/4hp. I would guess the trail blazer was around 1961.

That looks like a 'Deepco' driven pulley that was stock on many of the early trail scooters. The name should be cast into the opposite side of the driven and on the drive unit on the motor. Having the correct size belt is very important to the performance of the system. The Comet series 20 system is a good replacement and belts. Comet brand parts are better than the substitutes, so watch for the brand.

You're right on that Deepco Richard. The reason I did not recommend a 20 series clutch yesterday when looking up his part numbers, was because the wider belt and beefier mechanics are better on the heavier machines. I have had good luck with them. Also, because it is what what you used to recommend on these machines.

You're right Dave. Most trail scooters use a belt width of 7/8" which is the same as comet 40 and 44 systems. The Deepco system uses a 3/4" belt width which works with the Comet 20 system.

Ah. thanks for clarifying that. So he could get the Deepco driven working, and then slap on a Comet 20 driver. Way better solution. :thumbsup:

You guys are good. So this is the deepco driven. Looks like maybe all I need is the driver to get this going.

Is there anything I should look at or check on the driven? I see there is a snap ring on the back side I assume this is to take it apart.

Thanks
