Hi all, I saw this idea some years back here on EO, It apparently was thought up by a L-Cool member and posted with pics on their Landcruiser site. I made a simple unit up at the time and it has been sitting in my
camp tool box and untried since then, not knowing how good or not so good it works in a real situation. I noticed the other day that the Schraded valve was leaking around the valve hole in my spare wheel so i decided to replace the complete schrader unit. Simply place the standard jack as close to the bead of the tyre as possible and wind the jack down. I was surprised to see the tyre came away easily with very little distortion of the tyre and it broke the bead easily and completely from that one spot. I jacked in the Schrader valve area and replaced the unit and removed the jack and pumped it back up again. I used a piece of 50mm square, 3mm wall SHS and a piece of 2", heavy walled
water pipe, about 25mm long, faced it in the lathe and welded them together. The Pics shown on the L-Cool site show a landcruiser jack with a hole through one side of the tube, and a spigot coming down through the middle of the part they made up, obviously for stability. The jack on the Patrol is bigger in diameter on the telescoping part so you can not locate inside the tube but i found my simple method vey stable and controled and worked
well.. MichaelImage Could Not Be FoundImage Could Not Be Found

I forgot to say that i will cut off another piece of tube and weld it to the underside of my towbar gooseneck and it will be with me whereever i go!! Michael.
P.S. I think there is room under the gooseneck!!

Micheal,
like the idea simple and quick with very little extra weight to carry
Instead of welding to the underside of the drawbar tongue you could make up a locator with a bolt spigot that would use the towball hole

Yes! That's another good idea. The basic idea is there and it works unbelievably
well, others can tailor to their own needs. Basically the tube is to stop the jack flying out under load, so there are plenty of options.. Michael

Just thinking about the towball hole idea, That may be better as most goosenecks have a 100mm offset in them . I only just had enough room to get the jack under, and then that was up an incline which would have given a little more room than on a flat surface.. With the offset in the up position, that would increase the jack area.... Michael

I used a highlift to break the beads of the Karavan tyres to get the pressure sensors out a few months ago. 'Easy as Bro' as you may say.

Gday John, I should imagine the Hi-Lift would do the same job but the bloody things are huge! I guess the vehicle needs to be set up for a Hi-Lift jack and you need somewhere to store them safely!!! Michael

I made something very similar but I cut a hole in the RHS to take the jack. I think that welding a piece of pipe to the RHS is better. Might modify
mine.l

Ray, I think i have realised why the L-Cool unit had a hole, it does two things, it stablises the jack and you get 45mm of extra height.. What you have is probably the best solution. see my follow up above. Michael

Hi Michael
I just use my Hydraulic jack under the tow bar and after putting some load on the jack simply bounce on the step and, presto, the bead is broken. Don't need to carry any additional gear and it works
well every time.
Was going to make a special plate for the jack but frankly I found I didn't need it.
Cheers Rod

Rod, I thought I would post this as i had no idea how many people owned Tyre plier or baulked at the cost and the size of them. I think the R&R unit removes the tyre and installs it back on the rim although i have no idea how fiddly that unit is. This really works for no cost.. Michael

Rod & Michael. too true! Thats all Ive used for years, the jack that comes with the car always has done the job. Never could see the point of spending all that money to carry more weight. If you have an older tyre that has been on the rim for a while it may take a couple of goes, but hey its cheep. Fairly standard practice in the bush. Cheers Tony.

Gday Michael,
I wrote that article about 5 years ago and at last someone's found it! Hehe
At the time, I was wanting to design a better beadbreaker - one that wouldn't scratch mags, and was keen to minimise weight in the Prado I had then.
You need to use the thicker wall 50mm RHS (just as you've done) - if people were to try the thinner fence post RHS, it won't go into the square hitch.
Cheers

Gday Phil, It works great, i made it years ago but never tried it.. I have plenty of punctures, either fixed with plugs or got to a tyre place later on.. Take a pound out ot the till Phil. Good work!! Michael

Michael,
I like using jacks as beadbreakers. My favourite was scissor jacks but these days, I use the high-lift. Below is a photo from 1978 when we did 3 tyres in a day in a Corolla on the
oodnadatta track.

Gday Richard, those thongs weren't spare - they were
mine - I was taking the photo. Those 155SR12 Steelcats weren't the strongest - thought about cutting out some sidewall to make more thongs, but they weren't thick enough . hehe
Dave, that was a couple of mates in the photo. In the old days, you could fit 3 in a Corolla, and still travel throughout the outback in summer!
But if you want to see me with hair, here's another where I was testing the theory that if you grew it long, it wouldn't fall out..........proved that one wrong :-)) BTW, that was my first real 4wd!

On the last few outings, we've just used the vehicle itself by driving up on to the tyre as close to the rim as possible. Two things I've found always help though in either of these situations, a good dose of soap
water around the rim and taking the bloody valve out - Ha!! I won't divulge which EO member left it in and wondered why it took so long to slide the tyre off.....will I Scotty!

but a good learning post for people who didn't think of it.

Thanks Michael, that's so simple its not funny.. We always seem to look for fancy ways of reinventing the wheel (no pun intended). I'm gonna modify my recovery tongue on Monday. But I might need to make an adapter because of the amount of lift on my 4runner.

A timely reminder of an old and simple practice.
It was a popular way of getting 7" widies off 12" Mini Minor rims.
There was no other way it could be done other than by using heavy duty workshop equipment.
Just imagine: wide JJ alloy (and easily damaged) rims, run hot on forestry tracks, run flat to a safe place to stop, consequently melting the rubber to the rims. Add to that the very tight arc of the rim and the low profile of the tyre and there's your recipe for producing copious quantities of the proverbial 'blood, sweat and tears', tears(rips) to sidewalls, blistered and busted hands, broken toes (from kicking the bastards) and irreparable damage to one's reputation as a cool, collected, controlled and capable crew member.
All at 04:00 on a frosty Sunday morning and all in the name of sport!!!
Jeez, it defies all logic.

Michael,
I have something I purchased many years ago (but cannot remember where) that attaches to the bottom of a high lift jack and uses the weight of the 4wd to break the bead. Works really
well.....

Well, it seems obvious to some that this a good way to break a safety bead but also it has, as mentioned above, shown many, something very simple that may get them out of trouble when they need it most. I was amazed at the ease of operation myself.. Thanks to all that replied and to Phil G for the original idea. This
Forum is a great way to pass on useful information and i think we have done it here today on this thread. Thank you everyone. Michael

Friends of ours just north of
St George in QLD (cattle farmers) he has a piece of un equal angle 2" x 3" 2.500" long, the longer side is ground up and rounded corners.
one to two hits with a hammer and he had the bead broken on a 4WD navara steel rim.
Made some when we got
home and tried them out on some 13" off the 6' x 4' trailer worked a treat, I still carry them as
well as the TP's

would work fine if you have the time- but when time is money and a rapid couple of tyre repairs sees you back on the job quicker
