Spring bolts for F.A.S.T. clutch

[2004LEBanshee]

I have a clutch from jeff and I was wondering what spring bolts everyone is using. Also what kinda clutch boss.

Reason I ask is I tried using stock bolts but I broke one or two trying to tighten them. So I bought matching bolts from the hardware store and got washers to go with. I used these for about 6 months and had to take the clutch apart due to a wreck. When I went to re-install the clutch I noticed that my washers had too big of a whole compared to the bolt and tore up the end of my clutch boss posts. I went to the store bought a new boss, longer bolts ( the short ones I thought were to short for those springs) , and new washers installed the clutch. I made two passed at the local dirt drags and one of my posts which the bolt goes through on the clutch boss riped completely off the boss.

I run the stock bolts. When you tightened them the first time did you use a torque wrench? I believe the manual says 7 ft-lbs if i remember correctly. If you use thread locker or lubricant on the bolts before you put them in, that is too much imho. I put blue loctite on them and only go to a couple of ft-lbs and leave them be, never had a problem.

Yes. When I first put my motor together I tried to use the stock bolts with the new clutch. I dont think I even got to 7 (your right about seven) they just popped. ON or two out of the first 4 I just said f*ck it and bought different bolts. So your saying you use a stock inner hub or clutch boss and stock bolts. You blue locktight and use less then 7 LB's.

Yep all stock stuff, blue or purple loctite, whichever is closer to me at the time LOl and torque to about 4 ftpds or so. I use an inch pound torque wrench set to 48-50 inch pounds. works good for me.

 

Just a thought, but what brand torque wrench are you using. If it is a cheap one and it is in fact a ft/lb wrench, i wouldn't expect it to be very accurate down at the bottom of the scale which 7 pounds is going to be near the bottom of any ft/lb wrench. Thats why i use a 1/4" drive inch pounder

Yea it was from sears. Probably not the most accurate. In fact I bought it when I build this engine last winter. It is foot pounds and it is at the bottom. Im going to have to try one like you mentioned.
