belt tension

[Twodog185]

You're the man.

So, if I used my Krikit gizmo, and showed 200 lbs, that would equate to 890N.

One thing to consider is "belt wrap". On my blower bikes it's a fine line to get enough belt wrap to where the belt won't slip on the pulley. This is a non issue on the Spyder seeing we have so much belt wrap. There is no way you are going to slip that belt with as much wrap as we have. I think you could safely back off the tension to 200lbs and reduce the wear on the belt and the bearings. I'm running mine at about 250 right now and I can't see running it any higher. This ain't a Boss Hoss belt or Boss Hoss power.

by turning screws clockwise does that pull axle toward the rear?

yes

Does anybody have a gates/kricket thingie for sale? Amazon wont ship it to canada. I checked with napa and they no longer carry it in canada. Theres no listing on ebay for that perticular one either, just way more expensive ones.

Yes, clockwise will tighnen the belt.

Belt tension checker

The tool that spyder man has is also available at carquest. Here in north central FL it is 18.47each

I've got the Gates tool now, thanks to your earlier posting, Lamonster, but i seem to get significant variations in my measurements - all so far are between 200 and 300... I've been careful to reset the lever to 0, measure near the belt's center between the pulleys, center the tool on the width of the belt and push with one finger in the correct location. Still huge variations in measured tension.

Am i doing something wrong, or is this just a measure a bunch of times and average the results kind of tool?

You're doing something wrong or there is something wrong with your tool. :dontknow: Mine is the same every time.

Different readings on tension

I got the gates tool yesterday and tested my belt tension both cold, sitting overnight, and hot, after riding :yes:about 10 miles on a 90+ day.

Measurements obtained per shop manual procedure but with the wheel on the ground and no jack lifting.

Belt cold
Cold - spoke aligned 280
Cold - centered between spokes 240

Belt hot
Hot - spoke aligned tension exceeded guage max of 320
Hot - centered between spokes tension exceeded guage max of 320

Is this normal and acceptable? I thought heat caused expansion or caused a belt to losen.

I need guidance here. Sure would not want to run it to tight and eat the bearings or belt up. Only have 150 miles on this SE5.

That seems high. The last time I used the Gates tool (cold) to set it, it was at 225... I don't like tight, either.

After that, the dealer measured it with the sonic tool and it was on the low end of the acceptable BRP range.

It's most likely the rear sprocket heating up and expanding causing the the readings to increase.:f_spider:

 

[krb1945]

Thanks for the information... I completely forgot about the sprocket expanding when heated. Little gray cells aren't sharp as a tack now.

Also when I said cold... the temp in the garage had been in the 90's but the :spyder2:machine had not been on the road yet.

Thanks again.

Looks like a trip to NAPA.

pictures please

For those of us less mechanicly inclined, could someone post pictures of adjustment screws for belt tension and alignment? You guys are a brilliant bunch. If I could do what ya'll do with mods and improvements, the service shop would go out of business!

Thanks,
Scott:spyder2:

Here you go... one Allen-head bolt on each side... clockwise to tighten, counter-clockwise to loosen belt... after you loosen the 36mm axle nuts. <<Fixed the loosen/tighten stuff>>

awesome

Stay healthy atadude, we need you!:2thumbs:
