1947 Farmall Cub

Since the engine is an inline 4 when one piston is moving up another is moving down so the crankcase volume doesn't change. So crankcase ventilation is only needed for blow by.

There is a narrow tube that runs from the front of the engine to the air cleaner. It's tucked to the rear of the air cleaner so you're not likely to notice it with the hood on the tractor. Presumably its purpose is to provide some positive crankcase ventilation. Supposedly they often get clogged so you might pull it off and make sure it's open.

If you're blowing a lot of smoke out the dipstick though you've probably got a ring problem. They might just be stuck from sitting and might clear up from operating it some.

I went used it today and it didn't smoke at all. It did sit a month before I brought it back home.

 

[bbuckler]

I need to change the oil in the final drives and see if they quiet down.

 

[bbuckler]

I started to pull the pans and then decided to wait until I have fluid to go back in them

 

[bbuckler]

We got the clutch in but got to split the tractor again because there is a little chatter

 

[bbuckler]

We got it back together. One video said 7/8 so that what we adjusted to come to find out it 1-1/4 so now we got it adjusted right it works great.

 

[bbuckler]

Hoping to get the hydraulic parts next week. I got the touch control kit but I still need the filter , boots and pump kit

 

[bbuckler]

 

[bbuckler]

Hydraulic pump is rebuilt now to move on to the touch control

 

[bbuckler]

Got it all back together all left is add fluids and see if it works

 

[bbuckler]

Hydraulics work great now waiting on carb kit and sediment bowl gasket because both decided to start leaking some

 

[bbuckler]

Hydraulic pump started leaking . I'm going to build a block off plate until after the tractor show

Is it leaking into the engine or do you have an external leak?

External leak between the front plate and the body of the pump

 

[bbuckler]

Transmission seals are bad so I need to split the tractor again.

 

[bbuckler]

I got to looking and there was water in there again so it was thinning the gear oil out that probably why it was leaking. I changed it out again today and drove it in the barn in case it rains again.

 

[bbuckler]

Some days I shouldn’t get out of bed

 

[Razorback]

Ouch!

 

[MiCarl]

The good news is it's just a piece of pipe.

The bad news is it isn't going to be easy to dig the end out of the manifold. New manifolds are available though.

I hope maybe I can do it like the k series exhaust and carefully cut and chisel with out damaging threads. I also got a tap to clean the threads after
