Another Restoration Project

[aircommuter]

Here is the latest update. I finally got them all out. No.1 was the most challenging. It moved so slowly I had to measure progress with the dial caliper. Here is that movement log. Started with a measurement from the piston to the top of the sleeve. I would tighten the puller to maximum tension I felt safe without pulling out the threads I put in the piston, then go under with a 3/4" diameter punch and a 20 ounce hammer using 10 blows, then taking the measurement, then I removed the bearing insert so I could drive the piston down further to clear more rust. Measurements: 4.011- 3.965- 3.925- 3.820- 3.786- 3.745- 3.650- 3.410 then it kept moving just with the puller. The other ones all came out just with the puller but would not allow me to turn the crank until numbers 1,2,5,6 were out, then I moved it enough to allow me to pull no.3, with just no.4 remaining I could move the crank only slightly, so I put the puller on it and finally they are out.
I measured the crank and it is perfect size, round and nicely polished. The sleeves are next.

If this were Egypt 4000 years ago where they had a god for just about everything, you'd be the " God of Patience."

Slow but sure, things are being done almost daily. Sanding, sand blasting priming and component painting. Replacing fuel linkage ball joints with Heim joints. Chasing all threads. Removing the sleeves, scraping gaskets, cleaning the connecting rods and transferring them to the new pistons. I repaired and put new bushings in the throttle control clutch assembly. New hardware was used in most places. I also replaced the water separator with a separator filter combo. Many more small but time consuming tasks.
I am picking up some dry ice in the morning for installing the sleeves.
Also I made a couple fittings to convert from metric O-ring type to JIC and purchased some other fittings to adapt from metric internal seat to JIC also. The JIC fitting conversion makes it easier to get or make hoses from my own stock of hose and fittings.

I sometimes think that I would enjoy doing something like this, then I read what you are doing, and quickly realize that it's a lot more complex and time consuming then I imagine. It's more fun watching you do this then trying to do it myself!!!!

Just like TV they make it look easy.
Today was miscellaneous, replace main bearings even though they look and measure perfect. I used my dial bore gauge and the cylinder sleeves all checked well within specifications. Those main bearing cap bolts call for 180 ft lbs of torque and laying on my back between two tracks is a challenge at my age. Maybe I can get my wife to help me put the pistons in tomorrow, if not I will just have do a little more crawling in and out.

I got all the pistons in and the pan back on by myself. The weight of the rod and piston assembly allowed me to just push them down part way and from below pull them down the rest of the way. The rod bolts have to be installed after the rod is seated on the crank journal. I did 2 at a time. I spot glued the pan gasket to the block and put in 2 guide studs, lifted the 80 lb pan onto a floor jack, the rest is obvious. All very simple stuff. There are three bolts in the back of the pan that thread into the bell housing that are quite hateful. They can only be turned with an open end wrench and and one partial turn at a time. They are blocked by a large cross support that holds the front of the machine. All the bolts are fine thread on this engine. Pretty typical British like the Jaguar engines I have rebuilt.

I have been putting the engine together and I filled it with oil through the oil galley with the pressure tank in the picture. I like to fill newly assembled engines this way, then everything is filled.
I also drained the hydraulic tank and replaced the filter and breather.
I am also draining the transmission and other oils while I am inspecting and repairing things as I go.

Very impressive!

I am still working on this project as time allows. I have finished the water pump, fan and alternator. I had make 2 special banjo bolts for the bleed off line. I couldn’t locate the ones that have a connection on top for return to the tank and one to the filters. I drilled a couple stock bolts and tapped them 1/16” npt. Then I used a 1/4” barbed hose fitting in them. (Picture)
I have removed the brake bands and sent them in for relining.
I am also fabricating brackets for the air filter which I didn’t get with the machine. I have also been re-threading numerous holes and removing broken bolts.
I started bending the stainless tubing for the fixed hydraulic lines on the loader boom.

Here is the latest, I couldn’t find pedal pads so I made these plates to fit a readily available pad close to the same size. I welded some 5/16” flathead bolts on them then just drilled the steel plates on the machine.
Then I finished fabricating the air filter mount. I got the filter assembly and the pre-cleaner from the Donaldson catalogue. I sized it from their chart using engine displacement.
Lees time to work on it with so many summer projects. I had some epoxy stored in my basement that was approaching shelf life so I switched to that for a bit.

Really appreciate your attention to detail. Have you started the motor yet?

Very nice progress! Did not know M-F had crawlers state side, I know You can get them in Italy & it's looking awesome & I like your conviction .

The hydraulic feed tube from the tank to the pump passes directly over the brake access cover. So with an emptied tank I can’t fire it up yet. Brakes should be back sometime next week.
I also want to drain the transmission and final drives. Then all the oil the machine has will be new. I like to know where I stand as much as possible.

I had a little time today so I started sanding and removing old decals. I plan on painting the operator’s area while the battery box, seat and dash are removed so I can do a better job and put those pieces in and I will have all the gauges when I start it and not have to use jumping devices for battery and starter.
The one picture inside the tractor shows the right brake cover sitting in place without bolts (upper part) then at the bottom of the picture one can see the large suction tube from the tank to the pump, and the left brake cover is under it.
Then there is a battery box picture already sand blasted and painted with two new nuts atop the hold down studs. The nuts were missing but I had some and they were metric extra fine so I had to order a die to clean the threads. Probably why they were missing after they lost them they couldn’t find the extra fine ones.
The seat assembly sits on top of the battery box. Also in one picture.
There will be more painting stages once it is running and I can position the loader and ripper as needed to clean and paint all the places.
In the next post I will explain what I found wrong with the fuel system that probably led them to remove the injectors which wasn’t likely the problem and ultimately caused them to lose this machine.

Is that a tube gauge on the side of the machine that is broken? That wouldn't be good in a dirty environment.

Same Donaldson Air Cleaner that is on both of my Kubota M9000's. Botha are turbocharged. Donaldson makes all Kubota air cleaners far as I know and you may have a double filter air cleaner. Donaldson makes both an outer pleated paper filter and an inner paper filter as well for that housing. Both mine have the go-no go restriction indicator but I may install gages on both mine as it's a simple upgrade.

Yes that gauge is the fuel. I have the tube off. I am replacing it.

That is a double filter unit. I selected that option as I have always had them in the past.

I have been dividing my time with early mornings while it’s cool working on the tractor then switching over to the house work.
I got the brakes back and they are in the housing but I have to hook up the adjuster and go through several steps for the adjustments. The steering clutches get adjusted now also.
In the one picture of the band you can see two little metal strips. That is the bottom of the band and an adjustable support bolt comes up from the bottom of the case. That supports the band to keep it centered around the drum.
I know one isn’t supposed to sand a tractor. I just didn’t want see all those scratches and chips every time I went to get on it.
While sanding I have found all the decals they painted over and I took all the individual measurements so I can have them made as original.
The story about the fuel system i that one of the olive type seals was put on incorrectly and the rubber was blocking 3/4 of the fuel line and the hydraulic oil cap and the fuel caps were reversed. The hydraulic oil cap isn’t vented. I think is was severely starved for fuel and they blamed the injectors.

 

[EddieWalker]

I didn't know that there was a place that would make the decals for you. I always thought you had to hunt and search all over to hopefully find them somewhere!!!!
