Recovery Points - Cutting Chassis
Hey guys,
I've got a 1999 GU and it doesn't have recovery points...yet. Now, I'm planning on using it the way it's supposed to be used so recovery points are a must as far as I'm concerned.
My dilemma:
Got a TJM steel bullbar which needs to come off in order to access the ends of the chassis rails if I'm to open them up to get washers and nuts in. However, I was having a look around today and wondered if you can cut the end of the chassis rails right off? There's nothing attached to them and as far as I'm concerned they don't do anything in terms of the structure of the chassis.
By doing this, I'll be able to easily slide the nuts and washers in without removing the bullbar.
Has anyone done this or know if this is a big no no in terms of safety, legality, anything else?
Here's a picture to show what I mean.
Green = area covered by bullbar
Red = cuts
Yellow = bullbar mounts

G’day mate, please do look up a Vendor on here called ‘Outback Recovery’ I believe it is. They will mount up easily below your chassis rail (W/SW) of your lowest yellow arrow pictured above. Cheers!

@MB I think you had something like this done to your rig when the Millweld bar went on? I would think the ends of the 'box section' will need to be capped to retain the shape rigidity, as you are cutting fairly close to the load points for the mounts and the chassis rails are quite lightweight. Strictly speaking you are also altering the chassis so it should be a 'certified modification', but thats up to your interpretation at the end of the day until you get caught that is!

My advice is: not to follow my advice.

G’day mates, never suggested otherwise. There should be no reason why a standard TJM bar trek plan should need such? Old mate John on here makes an awesome compliant recovery point/s to mount below any TJM, ARB or most !

The mounts with the rusty hole witness marks look very accessible or am I not seeing something? Does the TJM bar slide over the chassis rails? I can't see why Johns mounts won't fit straight up.

Back on ‘charge’ apologies for delay @PeeBee Phil mate :-) John’s recovery points mount inline with all chassis’s underneath and bolts x 3 connect them with lateral force not front pull off I guess is the benefit/term :-)

So bolts in shear/double shear, not tensile loading?

Shear is load across the diameter of the bolt, tensile loading is the load pulling on the bolt in the axis of length. A bolt under tension will stretch before breaking, however a bolt under sher will deform in the line of load then shear or cut off, like a whipper snipper cutting thru grass.
