Case 900B stuck engine.

[rustred]

Here is my 900B with the American bosh pump. Every 900 B I have seen around here had that pump. This tractor’s was not changed over. 1958 model. My uncle had a 1957 and it had this pump also. So if they were changed over to the German bosh it was at the end of production for the 930 also

I will stand corrected, I have never seen one with short radiator, the PSB pump and have a B serial number! To be honest I don't remember if the one I had was a 57 or a 58, but it did not have the B in the serial number I do remember that. I can ask the fella that bought it if he will look for me some time.

@rustred He got back to me really fast, it is marked as 900, no B, and is serial 8107586, so clearly a 57 model year, I really did think that when they added the B they went inline pump but yours clearly proves that wrong, any idea where yours falls in 57 production? I don't have my Old Abes news near with all the breakouts to get down to the details

Far as I know 1957 does not have the B. Mine is 1958. And as far as I know the in-line pump was for the 930’s many old tractors had that old PSB pump. Massey Harris ,Massey Ferguson on the super 95 , which is a Minnie tractor, Minneapolis, case , Oliver are the ones I know of.

You will want to pull that pump first and make sure its free. They tend to stick when sitting and then something twists off when they are forced to turn. Of that happens they are junk and need to be replaced and that is expensive.

There are about 10,001 ways to go about freeing a stuck engine, none any better than any other. The key is FINESSE not brute force. It'll either come loose or it won't.

Curious, only 1 or 2 exhaust valves would be open at any given time... How'd you get the ATF into

It has a decompression lever on it that opens the exhaust valves.

The time you spent making special tools to break it loose , you could have the top end most of the way off. At the least you're going to need a set of rings. All this talk of a few thousandth of valve recession causing hard starting, yet you're ok with using the piston rings scraping rust off the cylinder walls and getting ground down in the process? Removing the top end will let you know immediately whether the motor has the slightest chance of being freed with these Neanderthal methods, and save yourself unnecessarily damaged parts.

I see on this forum continuously guys waiting months with their favorite snake oil to free the motor, and end up breaking it down anyway. They always have time to wait and hope, but never take the easy way out and just get it apart in a few hours.

yep yep,exactly , cause there is no hands on experienced mechanic's , that understand what a stuck engine is inside. so that tells the story here. rust was never my friend.
