    Posted: 22 Mar 2021 at 9:53pm
This past weekend, I purchased a 1948 Allis Chalmers Model B.
I now have 2 Model B's  (The other is a 1940 with hand crank).

The plan is to remove the belly mower from the 1940, and install it on the 1948.
Hoping everything goes smooth.

The 1948 drives real nice but I have noticed a couple things.
1. The steering is extremely sloppy. So much play in the steering wheel.
     I'm not sure how to solve this.  
2.  The clutch engages instantly, popping the tractor.
     To combat this, you must very slowly release the clutch.
     (Could it be I need a new clutch?)

Thanks for any advice

nice looking tractors... the sticking clutch could be oil on the clutch plates. The rear seal weeps and there is also a wick for lube... What i did was pull the starter, push the clutch peddle down and lock it .... then put dishwashing soap and water in a weed sprayer..  spray thru the starter hole and soak the clutch and entire area... crawl under the tractor and look for the 2 inch diameter hole under the clutch... spray up into that area.. SOAK EVERYTHING GOOD... wait a few minutes, then flush out with a garden hose... reinstall starter and test drive..
Like them all, but love the "B"s.

the steering slop is normally the steering box internals.. There are two different models, but you probably have the one with a  worm gear and "PIN".... the pin wears out and causes a lot of excess play..

Set in the seat and turn the steering wheel 1/8 turn in each direction.. Look at the output shaft on the steering box in front of your left foot and see that it has very little movement = internal SLOP.

 You can open the gear box, and see the worn pin... Some guys make new pins.. You drill out the old pin and press the new on into the hole... There are  aftermarket, or they can be made on a lathe.

I just finished rebuilding the steering box on my G. I believe it is the same Ross brand box as your B. It is a pretty straight forward job. Replaced the bearing races on the worm shaft and put in new ball bearings - Steiner's has both. I also bought the pin pictured but it was smaller than the original in every way. I ended up having my fab shop make up a new one and weld it in. Wow, what a difference! No slop at all. Also be sure to put a new oil seal in the bottom of the steering box as well.
