Parts for pto winch

Hi all.

A friend and I find our selves running two old crank driven koenig winches on our everyday/challenge/trophy trucks (a 90 and a 110). We have made the installation in two different ways and have therefore used mixed parts between the two. The pto shaft on my friends setup is VERY short (13cm) and was originaly (some five years ago) made up from old parts and yokes from an old toyota fj45 winch ptoshaft we had lying about... The problem now is, that for some reason the shaft is getting a bit worn... I for one don't understand that it isn't capable of doing full engine rpm's all the time, but it must be down to the toyota origin... :-)

Does anybody know a good parts supplyer for these toyotas? -or maybe just can find an exploded parts view with partnumbers?

Hi.

The winch is as posted above a crankdriven koenig winch, so no other connection to any gearboxes than the uj's on the propshaft to the winch comming from a toyota pto :-)

the propshaft is connected to the engine at all times, so running at engine rpm's.

I do know that this is a Lamd Rover forum, but being a long term "side line" reader of this forum, I kind of got an impression that some folks on here know their toyotas as well. The winches being mounted on a land rover and an land rover optional accessory in the 60's I found it "all right" :-) ;-)

By worn I mean that both the slidejoint between the yolks on our prop aswell and the uj's are getting sloppy. The crosspins are only 20mm long and the smallest we can find here seem to be 22mm.

The solution therefore seems to get some new uj from toyota, but alternative ideas are welcome.

we need a prop which is max 13cm compressed and approx 16 when mounted. It is running at an angle (I haven't got a picture but might be able to find one) and at engine rpm's.

As posted is our solution at the moment to get hold of new toyota parts -but from where, and what is it we actually got? :-)

Thanks, but I said what model, not what brand. There are many Koenig winches that are pto capable, some big, some small, some connect on the left, and some on the right. Google "koenig pto winch parts" and look at the pictures that are returned. You will see what I mean. :)

For myself, I would get new shafts made with suitable ujs at a driveline specialist. The slip joint is a slightly different issue but you can get those fabbed too. The angle of the uj may be the reason that they are chewing out.

Hi again.

as far as I know, there is only one crankdriven version, the lr591. One of these have been adapted to be mounted in a 110.

You are right about the custom prop and that might be the end of it, but the Toyota parts have performed perfectly and would be a direct replacement, so relatively easy :-)

the angle ob the prop is a bit of a problem, but on the other hand it have worked for some 5 years and was built from old parts. The hope therefore is, that some new parts would sort the next couple of seasons. :-)

Cool :)

IIRC the angle should not exceed 15º. If it did then it has probably flogged itself out. On mine (Thomas winch, not Koenig), I had a similar problem from a LT95 pto from the upper transfer case output. To get around that required two uj's and cushion bearing blocks mounted to the chassis, holding the shaft into a stable position. Different to yours I know, but just to illustrate an alternative to the single uj.

Here is a couple of pictures. Some more will follow, but he was in a bit of a rush today, something about yesterdays storm taking some roof with it...

As you can see it is a rather short prop, but it seems I was a bit wrong about the length -the prop is approx 19cm fitted. It have to be this short because the winch is mounted very deep in the front of the car, making the space between the engine and winch rather tight.

The engine is a 300 placed as a 2,5 n/a in the enginebay running a normally placed LT77.

The last attached pic is the best one I had of the winch setup from the outside. He will take some more soon.

Mads.

Its a smaller u/j than the mgb ones, and the application charts I found dont state a 3/4" x 2.5" u/j. I think with the flange hole locations one end and the 7/8" shaft the other, you should be able to get one made, albeit a bit pricey. is it just the u/js you want or also the slider bit?

Found it!

Remembered a couple of weeks that our local scrapyard actually specialises in old toyota 4x4's.. A quick call and I got a number and an uj. For any future reference the toyota number is: 04371-10011.

Sorry I didn't reply on the mgb idea earlier daan, but they are rather exotic here (Denmark) :-)

And now off to pack to the weekends adventue race!
