Looks good! That’s quite a bird house you have in the background. Is it for purple martins?

Hi,
The Cub looks good in your pic.

If the Cub has the IH carburetor, the low idle speed is set by the small adjustment screw, at the top area of the carb, on the engine side of the carb.
Below is a pic from TM Tractor of the screw, it should have a spring on it.
The rod ahead of the carb has to be pushing back, when the throttle is in the rear position, to close the throttle plate enough that the end of the screw touches the stop. :)

Congratulations on a job very well done. I was pleased to see that you kept it 6v. I am a traditionalist. Keep up the fine work, and you'll have many memories built with your Cub.
Why is there never enough time to do the job right, but always enough time to do it over. :?:

No - it's for starlings (sturnus vulgaris)

They are extremely effective against harmful crawling in the garden. And they are spectacular to watch when flying in flocks of hundreds of thousands. Try to search murmuration.

Hi Glen,
Thanks for your wise direrctions.
It is an IH carb.
I've just read what the Service Manual states about gov.-carb. link and low idle adjustments, and must admit that I was way too hasty on this issue. :oops:
When I installed the carb., I turned the low idle screw to the bottom, and one turn back (I think I've read about that - somewhere). And then forgot all about it :roll:
I've just started splitting the Cub again, but when it's ready to start again, I'll strictly follow the Service Manual on the gov.-carb. and low idle adjustment.
Best regards

I’m familiar with starlings. We have them here, also. But, they’re considered a major pest here.

With the front end and the engine done, it’s time to split the tractor again for renovating the remaining parts.
First I drained the gearbox/transmission. It contained oil :) Unclear yellow/brown with no free water. From that, and from what I heard during testrun, I will NOT split it, just change oil seals, gaskets and cleanout with diesel oil.
Then I removed the left final's oil pan. Remembering Dale’s warnings in another thread, I did manage to contain the mess.

Removing the right finals oil pan made no mess, as there only were traces of oil in the bottom of the pan :shock:
IMG_20190428_102238.jpg
Then split the tractor.

Real split.

Well - my good friend

tells me, it's time for a walk before bed time, so I have to postpone further update.

Front part with wooden wedges and home made support bolted onto the starter motor flange.

IMG_20190522_114734.jpg
Bearings in LH final looks OK and spins free, so they will be put back in service together with new oil seals and new gaskets.
Bearings in RH final are doomed. Too much clearance, rusty and don’t really spin. To be replaced.
Then time for cleaning the major parts for sticking and hardened gunk built up over decades.
Ordinary methods didn’t work, so I loaded the parts on the truck, and visited my good friend. He has a hot water high pressure cleaner (200°F and +2.000 psig). It removed the major part. The rest must be removed with chisel, hammer and rotating wire brush. Very wet and dirty job, so no pics.
Inspection of the gearbox/differential housing revealed two holes.
No expansion plug in the PTO shifter shaft hole. New will be bought and installed.
IMG_20190520_163238.jpg
One of the bolt holes for the differential shaft housing goes through to oil side.
IMG_20190520_163213.jpg
Must remember to seal when reassembling.

Removed the covers on the gearbox and the differential for replacing the gaskets.
IMG_20190529_170313.jpg
Nothing to notice inside, besides being surprisingly clean. Only a small amount of sediments in the bottom, which was flushed out with some diesel.

I've just ordered bearings, oil seals and some minor items from TM :shock: :cry:
With a little luck, the parts will arrive here in 10-11 days time.
Until then I'll be cleaning parts :(

A period with lousy, rainy weather is good for the Cub project.
The torque tube did not have any drain hole for early warning of leaking oil seal.
IMG_20190608_080450.jpg
Now it has! I drilled a 3/8” hole in the bottom of both ends. Pic unfortunately lost during fumbling with the phone (neither first, nor last time) :cry:
TOB fooled me as it looked more like steel than graphite. Found a thread on here where graphite v. thrust bearing was discussed. It enlightened me :)
The thrust bearing TOB is quite new, so I will stick to that.
Installed the torque tube and gearbox/transmission (with new oil seals).
IMG_20190629_171150.jpg

Timely I found out, that the transmission tube has to be fitted to the right final FIRST. Otherwise you certainly will destroy the oil seal in the transmission, as you can’t see and control the shaft when it enters the seal.

Got the finals reassembled with new oil seals all over and new bearings in the left one, and then installed on the transmission. Then rear wheels on, and finally – the Cub is back on its wheels again.

Really a wonderful sight.

Next to come is cleaning the fenders and platform for rust and old paint :cry: :censored: It must obviously be sour before it gets sweet :roll:

Very nice work. I am enjoying your write-up and photographs. One question: what paint are you using?

Sorry for the late reply :oops:
When I started this project more than a year ago, I visited the nearest Case/IH dealer, to see if they could help with spare parts, fluids, advices and . . .
When I mentioned Farmall Cub 1949 they were lost. They knew that IH and Farmall was related, but a Cub from 1949 - :?: :?: :?: :?:
I also asked about paint for such a tractor – and then they lit up. They didn’t know about paint, but the person in charge of their painting department is quite well known for his interest in colors and staffage for vintage tractors.
After a long talk with him about tractor and implement colors, I persuaded him to mix me 2 litres “old IH red” (his name for an old Dupont color recipe). It is a “heavy duty” alkyd enamel they use for all agricultural machinery. It can’t be bought in paint shops, as it is too toxic for ordinary people. Normally you must have done a safety course before using it.
