    Posted: 23 Nov 2019 at 5:16pm
I just acquired a 1940 Allis B it is the same model my grandfather had when he and I would log the property when I was a young buck so I brings back some of the best memories I had growing up. I am looking forward to getting this allis running again but it has two issues one being the radiator fluid getting into the oil and the second is a clunk in the right rear wheel on every revolution, The wheel I am hoping is a bearing but the fluid in the oil my guess is the sleeve o rings being bad. I plan on putting 7lbs of air into the cooling system and pulling the oil pan to look for leaks as suggested on this forum. Assuming I have a sleeve o-ring issue can anyone give me some advice as to reinstalling the sleeves with the new O-rings is it hard is it straight forward are there some tricks to it?

Clean up any rust, sharp or rough spots.
If pits are too deep, use a good quality epoxy (Belzona) to fill the pits.  Sand smooth.
Use assembly lube or glycerin to lubricate the o-rings.

A bearing would turn many revolutions per revolution of the wheel. maybe just a loose rim to hub or loose hub to axle shaft. Lets hope.

Pull the valve cover and check the freeze plugs in the top of the head.  They tend to rust through and the coolant ends up in the oil.  If they are bad, your pressure test should show up any leaks here.

Do this first. It could be what you are thinking, but more likely the freeze plugs.

I agree...pull the valve cover first and check freeze plugs. I had the same problem on the WC, and it just a rotted freeze plug. Quick and easy (and cheap) repair...Dan

I agree with the posts about the freeze plugs. I will add that they may look good from the top, but may still be bad. I would remove them and I am betting you will find at least one bad plug.

As for the wheel clunk, the bolts that hold the rim to the center had an eccentric or cam on them. Make sure the cams are extended and the bolts are tight. I'm betting that's where your noise is coming from.

As for the clunking in the wheel, one clunk, per rev says wheel clamp(s), as others have said. If it were a wheel bearing, a constant grind or squeal would be there, and may disappear with a brake application, to the wheel, in question.  Grab the wheel in question, and rock the whole tractor, side to side, and see what moves or clunks.  Repeat the rocking, after rotating the wheel a quarter turn...Wink

gman,
 Welcome to the forum! If you can post some pictures that would be great. These things are similar to calling your doctor and asking him to fix you over the phone. Sometimes he may get it right. Giving more information will always help figure out the problem. Good folks on here to help you with any and all Orange issues! I like the little B's! Don't ever tell them they are little! They think they are a big tractor!:) Spent many hours on ours on the farm. Hauling wood was its favorite job!
Regards,
 Chris

If you pull the head to change the sleeve rings, might as well replace the core plugs (aka freeze plugs) also, they could very well be going on 80.
