73 - 77 B80 hub interchangeability? 4spd/8spd

Recommended Posts

Will the rear hubs from a 74/75 4 speed work on a 77 8 speed?

Thanks!

Should be the same. Be sure to check the axle size, 1 1/8" or 1"

That's the thing.... I'm fairly sure the axle is smaller on the 4 speed. I was hoping the hubs would interchange.

I'd love it, but it's a bit too far away. ..

I think in 1974-75 they used model 5080 and 5084 transmissions. Both 4-speeds with 1" axles.

Tractor models 1-0140, 1-0141 and 1-0145

 

The 1977 8-speed should have 1-1/8" axles.

 That's what I was thinking. I found an 8-speed to put in my tractor but it does not have hubs. I guess I need to search for some hubs...

The 1977 8 speeds had 1 1/8" axles. New 1 1/8" hubs with the key and set screws is a little over $100 each. I bought one back a couple of months ago. I was for my 1977 C-120/180 it's been modified, and repaired over the years to the point of it being rebuilt with out a complete tear down. Any lose fit of a hub is going to cause future problems be it a worn key, key way, or bore. They will cause the hub to shift and ware off the point of the set screw from their every thing gets worse. The C-120/180 has been my main working tractor for the last 40 years and I plan on keeping it until I don't need one any more.

I won't order til I can measure the "new" axles but What's your source for them?

 

I can see us keeping this tractor at Least the next several years... or more...  so I want to build it right so it'll last.

I got mine from "PartsTree". I call down there first to see if they were open, this was a week or so after they got hit with hurricane in Texas. I then ordered the parts on the computer.

 

There part number Is TLB 105763-03  Hubwheel  $96.62 the shipping to NC was $7.95

I think the price is going to be about the same, maybe a couple of dollars difference. I checked a couple of places and found some a little cheaper but farther away so I guessed the shipping would be more.

While there are some 8 speeds that have 1" axles (what Garry said)...there are no 4 speeds with 1 1/8" axles...except the heavy duty bevel gear trannys.  :)

@A-Z Tractor will be able to sell you some good hubs, he will inspect them and won't sell any junk.

:text-yeahthat::thanks:

 

Called him.

That's likely the way I'll go.

I may also need a long hood and he'll ship all 3 (2 hubs, 1 hood) for a great price.
