Default 8274 winch info and builds

Let's tear down, rebuild, or modify 8274 winches.

There is interest in the subject and we can use this to discuss and share everything in the wide world of the 8274.

There is fantastic aftermarket support for these and a few different companies building very high quality upgrades. Research the subject and one quickly sees the potential and benefits of having a faster, more powerful, and efficient winch.

There are a few guys and gals here in AK that have some experience using and modifying these monsters and some builds on the horizon so hopefully we can get some positive feedback and share some good info on the subject.

This could be an interesting topic. I've been looking at either an 8274 or a new Powerplant HP

Copied from other thread.



"There are some weak links in the 8274s that could be a concern on a double motor setup.The end plate the holds the drum is a weak link for sure and could use upgrading.

The top housing runs roller bearings on the main gear and these are known for walking in and making the gears run at an angle and destroying the winches. You can up grade this with bronze bushes and new idler shaft to eliminate this problem.

The main shaft is the next weak link in the 8274s the brake is held on by a snap ring that can shear off under high stress loads and you go into a free spool state and leaves your winch useless, you can drill and tape the shaft and put a retaining collar that preloads the brake to stop this from happening.

With a little work the 8274 can handle the double motor duties as long as it is mounted in a way the the housing wont flex and get the drum out of line, if this happens it will eat it self up.

I am playing with a 8274 now and will post up some differences I have found over the years and the different variants of the 8274. The brake has been changed at least twice I have found that there is at least two drum configurations some are as much as 4-5 pounds lighter and don't seem to suffer from corrosion like the later ones do.

And last but not least the free spool mechanism is a bomb waiting to happen. I have always drill and pinned mine to stop them from kicking out under a shock load. There is now upgrades for this problem as well.

Another very important upgrade would be the Albright contactors these eliminate the problematic solenoids the the 8274s suffer from.

Jason Bizarro is messing with the Albrights now and my have some input to share."

I'm going to be running the Gigglepin In-Line Twin XP Motor Adapter this summer to test the limits here in AK. This fits my budget well and will provide me with an improved winch set up to get me out of what I like to get into.

The plan is to use a new XP motor and an old well used ex comp. motor with a stock top and bottom housing. Along with the adapter, Albright contactor, and all the tricks and tips I can learn I'm excited to see what I can make happen.

As I'm waiting for the XP motor to have a shaft machined, might as well hook up the Albright and do away with the archaic solenoids.

All tucked in nicely. Noticed a smoother power in/out with this all ready.

I'd steer clear of the Powerplant. Haven't heard good things about how AK treats those

This is in my opinion the cheapest, easiest, and most beneficial uprade to a winch set up. Albright contactor.

The old out dated solenoids and bulky box leaves something to be desired.

For the casual user the stock cables can be re used- very easy to hook up and one can be had for much less than replacing the box and solenoids.

Wire in the controller plug and put it wherever you want. So much easier to wire for toggles and power shut off. Just plain better.

On a more serious note, 2 items to add to the 8274 upgrade list, 1. the composite bushing(s) in the end support for the drum, seem to cause drag if worn or dirty when freespooling, 2. A longer drum for more line capacity while staying close to the axial centerline of the drum for greater pulling torque.

On another note talking with Blackjack he recommends road ranger 50wt oil for these winches. I have used redline MTL with good results in the past. But I will give the RR 50 wt a go.

I just went with the the xp-2 contactor.... from what i understand it does the same job as the 9.5xp silenoids.... but i have more info to look up. just some preliminary searches say that.

Albright contactors are available anywhere automotive electrical parts are found, including eBay, Amazon, Surplus Center, Polar Wire etc. price varies greatly....beware! Good luck.

Thanks Shack, I guess I was wondering if it was a order only thing up here. I'll try Polar as I have a couple of other things I need that I know they have.

Default Re: 8274 winch info and builds

Ed and I kicked around the idea of getting some Gpin product here in AK and put in an initial order. The product is here and will be put to good use by a few already. There is interest in what the company has to offer the off road world and future orders are a real possibility. From mild to wild, this is fascinating stuff!!

Let's keep this thread about the various tech and builds and not get wrapped too much around the axle from where the parts are coming from--- PM Ed or I for any specific details as far as the Gpin product.

The cool factor for us is the different variations and configurations of winches and how different parts and pieces are, or have been, used. Hours can be spent when a couple guys are standing around a couple of tore down 8274's looking at the differences and possibilities. Just like many other off road topics it's addicting and you can get some real bang for your buck!!

A alternative source to off road sites is glider sites, high speed winches are commonly used for launching gliders, some of the same technology will apply. Its' been quite awhile since I've been to any of the sites.

Default Re: 8274 winch info and builds

This is what I'm starting with. Some of this has seen extensive use and I don't intend to be any easier on any of it. I like to winch and will be relying upon winching first and asking questions later.

8274-50 of an early vintage.

Best In Class motor and 100' of Plasma that were both used on Ed's competition Jeep starting in 2000 and have both been put through the ringer in the last couple of months by me.

Cool industrial control that will be wired in as a back up to the dash mounted toggles and power cutoff.

Stock end plate that will get a tab welded on it as a brace for the second motor.

This set up as it sits now is very usable and has a no load retrieval speed of 100' at exactly 60 seconds with a single battery at idle dragging the hook.
The additional motor and a couple of other tricks and it should be enough to do what I want and offer a very unique look. You know I like to be different!!

Tore down----

Everything looks in good serviceable shape. No adverse wear or visible damage to anything.

*note: Somebody else has been in here. Sealed up nicely and very well greased. No oil.

My plan is to upgrade the standard 8274 using off the shelf parts as well as a top quality wire Arctic Flex from polar wire. 1/0 awg for the motors and 4/0 awg for the main leads.
