Synthetic line on Warn 8274 question

[1911]

Recently picked up a good working Warn 8274 from Craigslist:

I'm going to tear it down and clean it up anyway. I'm also going to run synthetic line on it. My question is, does anyone know what length of 3/8" synthetic line will conveniently fit on the 8274 drum (made for 150' of 5/16" wire rope)?

I run 80' on mine and carry a 50' extension line....

for 90% of pulls, 80ish' is perfect...more likely to be on an inner layer where the winch has the most pull power, less likely to need to respool mid-pull when it bunches up on one side

FYI, the formula for calculating the approximate capacity of a drum is;

Length of the line in feet = Constant (below) X (the diameter of the drum core, plus the depth of the flange( in inches) X the depth of the flange (in inches) X the length of the drum between flanges( in inches)

Constant for 3/8" line =1.86
Constant for 7/16" line = 1.37
(Constant = .2618 divided by the line diameter squared)

In most cases the flange will extend beyond the outer layer of the line, therefore the measuremant for the depth of the flange should be taken to the depth of spooled line, and not the full depth of the flange.

Hope this helps

Thanks Woody, around 100' is what I was thinking off the top of my head because that is what is on the M8000 winch in my other truck and I've never used the whole length yet in any of the places I wheel.

I was actually hoping there was such a formula, so thanks. By that formula, I could easily fit 144' of 3/8" line if I wanted to, which is good to know though I will probably put less on as per Woody.

I found this website if this helps MASTER-PULL Winch rope

I'd recommend 100'.
A second solution is 80' plus a piece of 50' extension.
Cheers

I put 125' of 3/8" syn on my 8274. It looks like you could go 150' of 3/8" looking at it, but thats all i have so its all i need.

Thanks everyone for the replies.

One more question: how are you attaching the synthetic line to the 8274 drum? I worry that sticking it through the hole and doubling it back with a clamp (like the original steel wire rope) would possibly cut or wear the line where it rubs in the hole. I guess if nothing else I could chamfer the hole slightly to round off any sharp edges, but what have you guys done?

 

[roalco]

I think the best way would be to do as you thought, clean the hole and make it nice and smooth, then laed the line through and clamp it or if there is room, just a good stopper knot. The strain is taken by the full wraps left on the drum (I'd leave at least 6 at all times) and the end clip is just a retainer. i saw a neat idea once, a loop of 1" webbing (long enough to hold 6 diameters of line, one row thick), threaded on when installing the winch line, that kept the last 6 wraps from being inadvertently let out. Very clever.

 

[woody]

honestly, if you are pulling on that knot/hole, then you don't have enuf line You should always have 6-8 wraps left on the drum, and THAT's what takes the tension, not the knot/clamp point.

I tie a knot in mine once it's thru the hole, and put a washer on it so if it DOES get pulled all the way when unspooling, it doesn't come out.

 

[1911]

Thanks guys, I'll just tie a knot in the end inside the drum. No, I won't be pulling on it, just wanted to know what to do with the end.

125 minimum will fit on it - you will wish you had 150 feet on there. Or - cut the drum off and weld in a solid 1.5 inch shaft and make it as long as you want - put 200 feet on it if you feel like it. I added 3 inches to my drum and 125 feet looks like there is barely anything on there.
