MV dropdown

I am in the need of one dropdown rear housing for my farmall MV, the one I have is cracked and leaks right through a previous owners weld. If there is anyone out there that deals with the farmall Hi-Crops I could use his number. If you have any ideas on a fix I would like to hear it as well. Thanks for your help.

If you take the case off, and take everything off it,clean it up good, grind off the old weld, make sure everything lines up, get the proper rod, do a little preheating and post heating , it should be able to be welded up as good as new. but it needs to come off the tractor to do it right. or take it off,clean it up and take it to a professional welder to weld it up for you. If you know what you are doing it is not too hard to do.
Good luck

You are going to take it off either way, so why not remove it and clean it up at the weld area, and have a good weld shop look at it. If it is repairable such that it can be ground back to original contour it will last and be cheaper than transportation. Jim

Here's a related thread by another MV owner with bad housings. Last reply was yesterday.

Just curious. Looking at the sections of the parts book that you showed in the linked thread, I noticed that there is a reduction, both in the chain drive and in the gear drive. So an MV is slower than an M, right?
Is the reduction the same for the chain drive and for the gear drive? (From the pics the reductions seem to be different, but would you care looking at the tooth counts in the parts list?)
Thanks, Hendrik

Thanks so much for the info and the help..I am in the Bakersfield area about very six weeks or so if you could find an area map or street address for the cotton farmer I would love to track him down...Thanks again to everyone.., and my personal email in hixson19@yahoo

Andy,

I searched quite a few square miles south of Bakersfield on Bing Maps but couldn't find the farmers buildings.

In July 2007, I was in Bakersfield to pick up a deadhead load for my trip back to MA. The load was a Diamond Reo pickup truck going to CT. The origin was a body shop on the west side of South Union Ave, 3-4 miles south of Bakersfield.

I asked the owner if he knew of any old cotton pickers in the area. He sent me up to Taft Ave (medium confidence on that) and told me to go west for a few miles. I took a left on a road I can't remember the name of and found the guy. He had four MCH's and alot of other parts on pallets. He had two sets of chain drive drop boxes. We spent about an hour removing a cotton picker PTO off one of his derelict MCH's. I offered $100 and he accepted the offer.

My suggestion to you is to go to the body shop and ask the owner who this farmer is. Can't remember if I asked the owner (about 30 years old) or his ornery retired father who happened to be on site that day. Good luck,

Below is the link to the aerial photo of the body shop/antique auto restorer. The Diamond Reo is in the picture next to a Dodge van.

Chain drive has 17 and 18 tooth sprockets.

Gear drive has 44 and 57 tooth gears.

Harold H would know better than me but I think the cotton pickers may have had nearly the same speed as the row crops. It's possible that they had W6 mainshafts and ring gears in the differential.

Thanks, that is very interesting. You are right, the mainshaft (pinion gear) and the ring gear are also part of the equation, and, for that matter, even the transmission gears.
