Toyota PTO winch rated capacity.... (1 Viewer)

[Landpimp]

Dave, what I was trying to say was. That every US Land Cruiser broucure from the mid to early 70's up to the late 70's shows both the Warn and PTO as options, in every case the Warn is listed at 8000lbs and the PTO is not shown with a rating. Thats why I assumed the ad was for a Warn......as that is the winch that Toyota always shows a rating for and it's always 8000lbs.

I certainly don't disagree that the PTO is as strong(or stonger) then the PTO.

Might the Warn be rated for a rolling load and the PTO for some other type of load rating?

Well, now you've seen an ad that says nothing about the Warn winch. And, since the ad is about the available options, and the owner's manuals discuss the PTO winch under the section on available options, I think we can assume that it is the PTO winch they mean when they refer to available options. A Warn would be a dealer add-on. I suspect that since the owner's manuals were printed in Japan, the "one-ton" or "one and a half ton" capacity ratings were just a translation mistake or error or otherwise inaccurate. The engine manual has errors in it that are clearly that way. The ad I posted, however, was printed in the US (Sunset Magazine), and was more likely properly edited. I just can't believe the PTO is only a 1 ton winch. I don't think Greeny's winch would do what it does if it was a 2000 lb jobber. Clearly there is a lot of inconsistancy within the Toyota literature about what the ratings are. It is interesting that the rating Rick Donnelly reported comes out to almost exactly the curb weight of an FJ40. Same winch is either 1500 lbs, 2000 lbs, 2500 lbs, 3960 lbs, or 8000 lbs.

Sorry I can't help you with your parts problem. But as to the shear
pin and winch rating questions; no, you don't want to alter the
shear pin, you would stand a good chance of messing up something
else in the winch drivetrain. The 2000 lb rating of the PTO winch
means 2k of line pull, unlike modern electric winches where an 8000
lb rating means the ability to pull an 8k vehicle, or about 1400 lbs
of line pull. Using this conversion of about 6:1, a Toyota PTO winch
would be rated at 10-12k by the common commercial standard you see
on winches.

I just stumbled across a guy (He may even be on the list) who has, or
had, an original OEM manual for his factory PTO winch. He say's that
according to the manual, the winch is rated at 10,000 pounds of line
pull.

I have never been able to track down a definitive rating on these
winches before. I have been told every thing from 8000# (which sounds
reasonable) to 4500# (this came from one of the "phone sales" 'droids at
one of the larger Cruiser parts operations).

I know that they pull harder than any 8000# winch I have ever used,
but since they came with 5/16" (or the metric equivilent) cable, the
10,000 pound rating seems maybe a little high. Does anyone know for sure
what the right numbers are? If not, does anyone have a confident
"guesstimate". If the latter; Based on what info?

Thanks for posting that John..

FWIW..

I have seen three PTO winch set ups that people changed the shear pin in, and chewed up the bronze drive gear inside the housing that turns the drum...

Hopefully those who are using a different shear pin set up, have changed the gear oil in the winch, and are watching to see any bright metal appear.


Good luck!

Yes, thanks for posting that, John! It makes a lot of sense that way. I have never liked the idea of changing the size of the shear pin, but I couldn't believe the PTO was so weanie compared to electric winches. Apples and oranges winch ratings helps resolve those number differences in my mind. Thanks again.

I found this from a thread in the LCML from 1998. It is by Mark Whatley, who was the tech editor for the Toyota Trails at the time, and who is well regarded in the TLCA. I think it adds some expertise:

[glow=red,2,300] The next time you have a factory PTO winch to give away, send it this way.

The factory unit will out pull any 8000# electric winch you care to bring to
the
contest. And it will do it faster and for longer. An electric may spool in with
no
resistance faster, but with a load on it, there is no comparison. The Toyota PTO
winch may be rated at 8000# but it is much stronger than that. If you are
concerned about the shear pin letting go too soon (never seen this happen
myself)
it is a simple matter do drill and fit a larger one. You won't find any electric
units that will hold the amount of cable that it will either. They don't burn
out
or suffer corrosion problems or faulty solenoids at inconvienient times either.
An
electric will not pull long or hard with the engine dead, and in a pinch you can
remove speak plugs, and use the starter, motor to drive a PTO winch. Not real
effective, but neither is an electric with a dead engine and drfaining battery.

A PTo winch is more effectively operated with some one in the rig, but it is
not
a requirement. And a simple remote starter with a "deadman switrch" adds a lot
of
versitility too.

And this is specifically the Toyota unit.

The Braden on my '55 is bench tested to 22,500# before they let it out the
factory
door (it's only rated to 10,000#). With a 1000 pound load it will pull in the
top
layer of cable at over 80 feet per minute. It will hold 450 feet of 3/8 cable,
or
650 of 5/16. I haven't come across any electrics with specs like this.

Electrics are convienient, and easy to mount. That much we can agree on
anyway.

Thanks for digging that up Dave, great read.


My 8274-50 has 175' of 5/16 wire rope, which is going to be replaced by 125' of 3/8' Amsteel Blue rope.

I own Pto Toyota winches, they work great.

I will take my Warn.

I thought the idea of running the PTO off the starter motor "in a pinch" was a neat one. Obviously requires an intact drive train and engine, but not fuel. One could imagine using it upside down, too, or in a temporary situation where the carb was disabled.

In my experience, the PTO winch is extremely capable, also, one needs to look at the gear engaged for the pull, wraps on spool etc. I have used my PTO winch to haul big loads with ease, no stock shear pin failure with 7-8000 pound dead weight hauls. I use 1st gear typically as there is no urgency when doing a recovery. I have in fact snapped an older but serviceworthy cable in a recovery with the winch and upon inspection the sacrificial shear pin was intact and still in use. These winches are strong, durable and besides nostalgic, very useful IMHO...

A 12 year revive. Nice work!

Better late than never =)

Bad thing is the engine needs to be running to run a PTO.

 

[Landpimp]

Yes and no, according to the above info, you can run it with the plugs out using the starter, but in a way...yes the motor is running

Bad thing is the engine needs to be running to run a PTO.

Bad thing is the engine needs to be running to run a PTO.

How many times and how long a pull have you done with your battery???

Or 100 feet of 1/2” rope? Yes?
