For MacGyver fans-interesting problem?

is the belt overheating (rubber smell)? What size converters are you running and how much freeplay is in the belt ?
Belts fail from overheating due to slip and tension between the converters. If you are using a 9 1/4" driven you nay want to go to a 9 3/4" or larger.

Hey Jersey,

Just got around to measuring my engine clutch. It is 7.25" diameter and is a Salsbury.

Actually what I was intersted in knowing is the driven converter diameter. A number of driven units were offered.

And if drive is bigger then driven, it is pulling hard trying to make the driven spread em.

Ok, just measured it= 9.25"

How does that + Salsbury clutch figure in??

belt

how tight is your belt when your motor is not running?

[boncrshr]

Pretty tight, about 1" deflection. You have to bump the motor a little to get it on. It is just barely too tight to get on by hand.

The 9 1/4 driven converter is the typical 4 stroke application. Did you change the gear ratio from stock? I installed slightly larger center axle sprockets to compensate for the 25" Rawhide 3 tires. I did have a 9 7/8 driven converter on my Hustler. Never had belt problems, but never pulled a trailer. I forget but did you change the spring in the driven converter? You may want to give the driven end more spring tension.

When I was trying to get the proper tension on my 950 I called R.C. at route 6X6 to find out if he knew the measurement.He told me that the 950 should have 1 1/2" up and down measured at center with only the pressure exerted with your little finger. That's a total of 3" seems a lot to me but what do I know? I think that the next mod I do will be an adjustable motor mount. Then I can play with the deflection and see what works best! Just for reference this is coming from the guy who told me that I couldn't get 25" tires on my machine and that the correct length belt is no longer made for it. Guess what, I am now running 25" Mudbugs, which makes me wonder about the correct belt size.

Hey Jersey, I did change gear ratio on the drive sprocket from 30 tooth to a 40 tooth. Also went from a green spring to a red spring in converter.

belt tension

A friend of mine has a bigfoot 980 with the 25 horse kohler i was looking at it one day and the belt looked real loose but when wide open throttle the belt was very tight and she had about the same bely deflection that richard had told you i do know if a belt is too tight it will try to pull itself apart under a load what size motor do you have?
