Getting ready to tear apart a few B's

atlarge54 · Oct 5, 2010

I've been mowing with what I think is an allis B for quite a few years now and have finally decided to repair a weak clutch. I've also purchased two other B's to maybe assemble one other good tractor. All these tractors are narrow front ends and they have the flat seat like B's do. The numbers are 072715, 074097 and 081049 if I'm reading the charts right I have a '46 '47 and '48. All the motors run pretty good with the one I've owned the longest seeming to need some oil seals. What would be normal readings on a compression tester for these motors?

Any warnings or tips before I start this project? The two tractors that are new to me have some transmission noise which I suspect is bearing noise.

For compression shoot for 125.

Narrow front would not be a B since they did not come out with a trike on them only wide front. Serial number is just forward of the shifter and will start with the model of the tractor and then the number gives the year. Cs most commonly are the ones with the trike front so you most likely have a couple Cs on your hands. Same engine but wider on the rear end

They did make a kit for the B but I was wondering about that myself.
Probably C"s.

I was going by the picture on external_link and they look like a C but have a seat like a B.

My B and C both have the same kind of seat. Hard to tell kind of tractor by seat.

The B's and C's had the same seats. You could install an after market Monroe pan seat on both if you wanted to. The C's were wider in the rear.

The top drawbar is for a C and the narrower bottom one is for a B.

The wide drawbar looks like what I've got. So I must have three C's.

They be a bunch of B's around with C narrow fronts. Same as a bunch of C's around with B wide front on them.

Dick I know that but as I said (most common) so he is not very likely to have 3 Bs with trike fronts unless he ran into something odd some how sort of like me and all my Cs 4 of them are all 1946s and all my Farmall Hs are 1940s and I have 4 of them

Well as I said look just forward of the shifter and that is where the serial numbers are and if a C the number will start with a C if a B it will start with a B

i doubt your serial number starts with 0.. most likely it is a C not a 0. width of the final drive casese apart is the tell tail.. Also, all Cs have rear hubs that bolt on with 5 bolts like a care wheel. B can have that, but it is rare.

look how narrow the rear end is and how close the tires set to the seat. note that the wheel hubs press onto a shaft with a center nut, not 5 studs... this is a B.
