Winch fitting question

[87County]

Supercheap have a winch on special at the moment for $359. On looking through the instructions, it is indicated that the winch is only to be fitted with the fairlead alignment at the bottom (they call it the underwind position).

Supercheap, of course, is unwilling to advise any different fitment from the printed instructions.

I note that the ARB "winch" bar for the D1s have cutouts which allow for winch fitment either way up.

The winch would fit wholly within a 110 ARB non-winch bullbar (appropriately reinforced of course) if it was upside down -

the question is -- is there any reason why this would not be OK?

Pretty much all winches I've seen are fitted this way. If it'll fit in there as required and the cutouts will allow it then why not?

.... and which "way" might that be cluba ? A non-winch bar has no cutouts.

hmmm.... perhaps I didn't make it plain

Does anyone actually know why the following instruction marks "upside down" as not to be done ??

understanding, naturally, that both alternatives (right way up & "upside down") are behind the front of the bar

I'm wondering if by upside down they actually mean not to reverse spool the cable.
The winch is designed to work with the load in a set rotation of the drum.


I can't see why mounting it upside down and retreiving from the top would be a problem.
Of course you would have to think about rotating housings for the clutch lever and drain holes for the motor.
Have a read of this post on another forum...Need info on fitting a winch - 4x4 Earth
More research may be needed as I've not seen it done.

The top cut out on the ARB D1 bar is for high mount winches. You use the bottom one for all low mount winches.

If you do it as shown in the RH picture the winch will be running in reverse - which may make it weaker or the brake may not work.

I was actually refering to the reference to the two cutouts.

I had the same dilema when I picked up my winch 2nd hand. Ended up operating it to compare the wrap of the rope vs fwd/rev operation. Plus what I've seen the norm and it seemed like the way to go in terms of leverage on the unit.

Interesting the comment on mounting to at least 10mm plate, i got a generic mounting plate with the tigerz winch I bought (from a 4 runner) and it was flat plate 6mm would be generousdrilled for the winch and had two extention plates to make it wider to fit the chassis and bolt on. No angles or anything. just a 20mm overlap and stitch weld.

From a rigging perspective, "underwound" and "over wound" refer to the attachment points of the wire rope to the drum, this is determined by the lay of the wire rope.
Left hand lay (SWR) or Right hand lay (SWR).
If you mount the wire on the incorrect side of the drum, or under, or over the drum incorrectly the wire will not turn up on the drum neatly while it is under load. ie it will bunch up on top of its self instead of neatly along the drum. This will wear the wire more and kink the wire (under heavy load).

Test;
If you stand with the wire in your hand and it is running away from you and it is twisting (the lay of the wire) to the right, it is right hand lay SWR.
Most wire is right hand lay.
So now if you are standing behind your winch with the wire running away from you a right hand lay SWR will be on the right hand side of the drum and under wound. (so it must be connected to the right side of the drum)
If you want the wire to be over wound you must attach the wire to the left side of the drum.

If it is left hand lay SWR it is the opposite to the above (unlikely)

Having said all this most Chinese crap that is coming into the industrial world doesnt worry too much about good rigging practice and we end up with many accidents.

RR P38, your explanation provides a most helpful explanation, and Alien D2, your link to that other site about the Nissan owner with the same problem was also quite informative, thanks.

Since initially posting, the manager of the local Supercheap told me of one customer who mounted it upside down and had issues with rope laying (as referreed to by RR P38).

Thanks to all who replied for your input.



And, as a PS, and FWIW the direction of pull is not altered if it's upside down

That depend on which way you rotate it to get it upside down.

The one in the diagram would run backwards.
