The Rebuild

[hrpearce]

Hi Lionel,
The tractor is 40 Hp Ford made in Japan. I made a front 3PL for it years ago to make it more useful. The jib just replaces the top link on the scrubbing blade, it's easier to use on the front than the rear.

G'day Robert,

Thanks for the reply, I thought it looked a bit bigger than my tractor. The three point linkage on the front must be really handy and a big plus not having to look behind you all the time.

I only have a 28 horse power Yanmar 4wd which is too small to hang a jib off. I have a three point linkage jib crane and I am thinking about hanging it off a differential with wheels and mounting a triangle frame with a similar sized wheel hanging off the top of the triangle. Then using a hand operated hydraulic ram mounted on the triangle frame to lift the jib. At the back of the diff I would put a drawbar which hooks up to tow ball mounted on the front of the tractor. That way the weight of the load would be supported on three wheels and the tractor would just shift the whole rig around the paddock.

I want to be able to lift off the tray of my two trucks which both have motors that do not work at the moment and shift the trays into the paddock so I have access to the chassis and then use it to lift the cabs off too.

I will be using the thickest wall RHS to make it nice and strong. Do you think by looking at my sketch that my mobile jib would work? Nothing is drawn to scale just playing with the idea at the moment.


Kind Regards
Lionel

G’day Robert,

Yaven Creek is not far from my ancestral home of Temora. I am the third generation of my family to be born there. We moved to Goulburn before I started school. My family used to go back to Temora for nearly every long-weekend and holiday break. I got sick of being cold and moved to Queensland when I was 20 for the sun and warmth. I still have links to Temora as my Uncle and Step-grandfather still live there; plus lots of cousins.

Kind Regards
Lionel

Hi Lionel,
That lifting jib arangement should work well, I asume the front wheel is a castor wheel, the rest is just the maths of the lifting capasity of the ram against the leverage disadvantage of the jib to calculate the load it will lift at the end.
My cousin from Holdbrook maried a wheat farmer from Temora by the name of Erol Bishop.

G'day Robert,

Yes, the front wheel would be a castor wheel. I have a 12 ton high lift manual ram so it should handle the weight of the the timber truck bed and the cabs okay, I don't have remote hydraulics on my tractor nor a hydraulic pump operated ram so I have to do with what I've got.

Kind Regards
Lionel

I managed to grab some CMP time today, I got the replacement stearing box painted and did a rough job of painting the diff white to make it look a bit more complete. The third photo was taken of Vicki and I ariveing at Gundagai on a frosty morning for the Shean bridge open day. It was given to me at the last meeting and instead of scanning it I just photographed it to make posting easier (less files to look through)

Though before you install the box. With the modern equivalent for the SAE 90 called for in the manual all three of my CMPs have developed steering box leaks. Original lube they didn't leak even when full, clean boxes all new gaskets fill with SAE 90 they leak like sieves, particularly around the large adjustment nut at the bottom of the shaft.

Consider checking for leak before you get the box in the truck (easier to clean up the leak).

Now for the rest of you living in warm climates what are you using in the steering box and does it leak? Or have you found a good way of stopping the leak? Or is this a problem only on CMPs in New Hampshire?
