3400 Series BGB

[Brettw]

Sorry guys, searched the forums and can't find what I am looking for, although I know it has been discussed. Are the BGB's from a 3400H series and a 7100H series, interchangeable? If so I can repair the one I just picked up. A 3415H with 48" deck, 42" blower, weights, chains, front counter weight, electric lift and a good runner. But the BGb gears are junk.

I don't know 100% about the internal components, but I think they are.

I know you can use either gearbox in either tractor. Main difference is the end of the pto side of the crosshaft. The older one has a smaller diameter threaded end and flanged lock nut. The newer one has threads the full diameter of the shaft with a large lock nut.

Thanks, Sam, that answers my question. Naybe I'll have 'er runnin' by the end of the weekend.

Yes, and that shaft Sam is talking about is NLA. They all use the 3/4-16 threads now. THE BGB`s are the same except for the RBT with variable speed.

What is the going price to repair a BGB these days? I have 1 of each laying around but haven't looking into the parts lists.

My last bevel gear box cost $125.00 It came with some options however. It had the "tractor and engine included option". ^

If everthing is replaced with new parts it is over $400.00 depends on what is being replaced.

400...wow...that's alot of coin!

Yeah at first, but they will last 30 - 40 years if properly maintained and not abused. So, it is pretty cheap. Not many 30 - 40 year old MTD`s and AYP tractors out there.
