chain tension

[acg23]

i need to figure out a way to keep tension on my chain with out a tensioner. i am useing a band brake on the clutch so it will not work.. my engine plate is slotted but it always looses tension right after take off. would putting afew washers under the engine work?

get better lock nuts

i got nylon nuts..

they can loose their "grip" if they are used to much, replace them and see if it helps.

Ive seen set ups using a spring, seems to work...

spring won't work, when he accelerates the bottom of the chain is loose, when he brakes the top of the chain is loose ( since the band brake is around the clutch). so a spring tensioner would only work 1/2 the time.

yea,, i have taken em off a few times.. i was thinking bout welding two spacers behind the engine and putting a nut and bolt thru it. when i tighten it the engine will be moved forward and tighten the chain.

get disk brakes then u have a tight chain and better brakes

 

[acg23]

yea.. but i tryna work with what i have.. do you think the spacer idea would work?

 

[fowler]

may be give it a shot

can you draw up some kind of diagram of what you wanna do???

yup that bolt idea will work. But sounds to me like you just need some better quality bolts like grade 8 and good washers that wont squish and get loose

my engine mounting plate is slotted so by tighting the bolt it will push the engine forward tighting the chain.

IDK if that will work very well =/ I would do what porsche said and get new stuff first

Yea that would work well. I would put a piece of plastic or something between the block and the bolt though. Steel beats aluminum.

i got this welded up today and it works great. i tappd the spacer instead of putting a nut on the other side. also i used a hard plastic cap off a fuel injector to keep it from messing up the aluminum. it keeps the chain tight and is very easy to fine tune. for 20 mins of work it was very successful. my band brake works very well with this set up aswell. i am going to make a plate to mount it instead of a bolt and spacer to the sidecover. i dnt want it to break. let me knw what you guys think.
