OMG- 40 series driven unit on backwards??!!???

[supermanotorious]

I'm sittin' here trying to figure out why this doggone 40 series keeps spinin' at low RPMs, I then consult the belt's package and the charts on gokartsupply.com and realize I mounted the driven unit backwards- Would you agree that is that my problem?

Yes you need a different spring in the driven to run it like that and if you flip it you will need a longer belt and it looks like you wont have enough frame clearance

I agree BUT since this thing is hitting the road Sunday, I am going to modify the frame instead

The driven unit will "hang" like the larger sprocket on jackshaft #2, I'm not a fan of that but I'm out of options and time

Why does the driven unit "compress" when installed backwards?

actually, I will order that other spring as for now it looks like it won't spin if held at idle, I assume the spring is wound in the opposite direction?

would you please post a link to one?

UPDATE:

I believe it's the yellow spring part # 204524A

Ordered. http://www.mfgsupply.com/204524a.html

Way easier than chopping up the frame.

What is that machine anyway.? A winch?

 

[supermanotorious]

yes sir, from this thread, this is the only industrial winch I've built and could seriously be a game changer for Phoenix Winch, the client is super pleased, they're ordering 2 more winches from me and presenting this build to the cable manufacturer this week, I might not get any other orders for them, or I could get too many!

That is looking cool. One thing i would do is to put some sort of chain guard on. It just looks too exposed to be safe

 

[supermanotorious]

ah ha ha ha ha ha, look closer my friend, the chain is behind a wall of 1/4" makrolon, it's crazy clear

it helps if you look near the pillow blocks, you can see where I cut out relief for them

 

[landuse]

Oops. I see it now

**** that's a big spool!! My winch had 1000ft of spectre and that was heaps, this could hold 50 times that!

EDIT: yep works like a charm thx.
