A Light Recovery Trailer from Downunder

[Sam Scholz]

Hi fellow MV tragics,

I've been playing with wheels. Managed to get some 7.50 x 18 tyres in good condition, so I have been cleaning up some rims and fitting them up. The original size tyre is 10.50 x 18 and is only available (in Australia) in an agricultural tyre which has limited road speed and a very poor wear rate on hard surfaces. So the 7.50 x 18's are going to have to do for now. The 16 ply tyres will go on the rear axles and the 14 ply will go on the front wheels.

So, after disassembling the wheels I purchased, I removed the tube/liner and cleaned them and re-assembled them. The picture below shows the fitting of the liner to the tyre following the fitting of the tube.

The next problem which I did not anticipate was the mis-alignment of the studs. These I "massaged" with a large soft-faced hammer.

Then drop the tyre onto the rim inner followed with the rim outer. . . .

. . . . and then the nuts which had been chased with a 1/2" UNF tap. I was a bit surprised as I expected BSF from a Commonwealth country!!!

Finished them with a torque wrench set to 60ft/lb. I got the setting from a generic torque chart that gives torques for each size for coarse and fine threads.

And then I could fit three rims to the LRT more-or-less permanently. I am seeking another 3 or 4 18" 6 stud rims to complete the LRT in 7.50 x 18 wheels.

That is all for now. I wish for you and yours a happy Christmas and prosperous and peaceful 2020.

Enjoy.
Sam.

Good morning all,

Well, what memorable times we live in.

My overall plans have changed quite a bit recently, for obvious reasons.
As BTTT2020 has become BTTT2021, I have 16 months to do what I previously had 4 months to do.

This has opened up the possibility for taking the LRT to the MJCQ Swap meet at Caboolture in October, 7 months time. Only time will tell.

So, with the pressure off, I collected the LRT and brought it home.

I fitted the last of the 7.50x18 wheels, and loaded and strapped down the ramps. Man, they are heavy. I'll weigh one sometime and report back. Suffice to say it was Dennis on the crowbar and winch assistance.

As I had not yet replaced the axles after the trip to Corowa, The Glorifier needed to be towed up the wet grassy slope out of the paddock and up to the road. But once on the road, everything went well. We stopped to check all was well on the 15km trip home.

It seemed to travel very well, but I sure noticed the weight (41/2ton-ish), having to drive it like a well loaded truck. It is beyond me how these trailers, loaded with a 4 1/2ton Carrier were towed with a 3ton Chev CMP!?!

Anyway, it is home now and I feel like I actually own it now.

I have acquired a wheel chock as seen in the youtube video linked above, thanks Dave M . More on that later.

Have a nice weekend, BUT stay at home!
(Good excuse to get some restoration/maintenance jobs done.)

Hello all,

I have recently found the time and energy to make a sort-of return to the LRT.

The first job is to straighten the very bent stub axles mounted in the rear bogie rocker assembly. The bend can be seen here in the gap between the axle spacers.

The axle carrys a seal carrier, then a spacer, the backing plate and lastly a large spacer plate. These just slid off, a little too easily I fear. The remains of the brake backing plate can be seen, it has been oxy-cut off probably due to the bent axle. It is held in place with six 5/8" UNF bolts and has a spacer behind it, which can also be see.

To straighten the axles, I had long ago intended to use brute force in the form of a "porta-power" which I bought at a swap meet cheaply as it needed seals replaced. Having fixed it a year ago, I tested it and managed 27 tons pressure, so I figured that would be enough. I also have a fairly heavy "H" beam that I have used repeatedly to straighten stuff for many years and have never even come close to bending it. But I would also need to constrain the outer end of the axle while applying pressure at the inner end. To avoid damaging the axle end, I manufactured a collar designed to go on the end of the axle with a neat fit and hold it in place with the original wheel bearing nut.

And here it is in place. As it is not long enough to carry 2 wraps of the chain, I found a neat-ish longer collar to go over it to get the length needed.

So far, so good.
Enjoy.

Continuing the axle straightening, here is the setup described in the previous post.

One axle was also slightly bent forwards, dunno how that happened. So I could jack it from the rocker.

One question was how to know when the axle was straight, or straight enough. An engineer I know suggested the method in the picture below, however I ran into a problem I have seen before. That is that the whole assembly is so battle-weary that there is not anywhere straight enough to take accurate measurements from!!!
So, while this method is quite accurate, I couldn't make any sense out of it due to the imperfections in the axle. I ended up using a combination of a straight edge and eye.

The first axle I attacked was the worse one. I often do it that way so that they get easier as I do each one. The last two hardly took an afternoon!
And here is the finished job. Part of the preparation was disassembling all the brakes, which is the next part of this story.

Time for a sit down and a nice cup of tea.
Have a nice day.
