B-112 Barn Find

[David Barkey 23]

A friend of my father inlaw I have done work for was helping a long time neighbour of his clean out old sheds to sell the place (seniors down sizing large rural property ).  He found this in one shed , it had been in there for more than 15 years . Everything appears to be there but the grill and a belt guard for side pto .   I had it running last summer. Had to put a new coil in it , thats why it was parked .  It is currently apart in my shop . It all seam in great shape other than needing bearing belts and seals replaced ect. The only exception is the bevel gear box . It needs both gears front shaft and all bearing and seals replaced .  Hardest pat for me is accessing parts at a reasonable cost as I am in Canada . This is being restored for my father . He is into antiques . There is a family connection to Allis-Chalmers . My dads father had the local (Orillia) AC dealorship between 1960-64 .

The B-112V , the same as a Simplicity 3012V or 3112V, has a small, meaning 3/4" shafts and bearings, BGB of which several of the critical parts are NLA.

Can the box be replaced with the "newer" larger shaft box? 

I believe if it was a straight gear or hydro it could be done fairly easily - The cross shaft only drive standard pulleys. For a variable, I believe the cross shaft/pulley setup is special.   

Finding a used box or two (maybe attached to "parts" tractor) is probably the way to go.

I have managed to cross referenced all the bearing , some I had on hand and some I have ordered . I am in contact with a gear manufacture in southern Ontario and sent them picture and dimensions of the originals . I am hoping that it is something I can get here at a reasonable cost . The shaft I can turn myself . I just need to buy a wood-riff key cutter . Something I don't have yet .  The seals I still working on . 

[David Barkey 23]

Not one seized bolt during disassembly . A few dents , surface rust and dry rotted rubber seals . Not bad for the age of it . What I have not been able to find is what year it was made via the Ser. number . Does any one know where to find this out .? 

[simplewrench 580]

The best way to determine the age is the engine. Simplicity didn’t keep serial number records so if you check the numbers on the engine you can get pretty close.

If you are making input shaft they are hardened where the needle bearing runs.

Very good idea. The 3310V and 3314V have big BGBs thinking it could be switched but I also think the variable speed driver pulley mechanism would need to be changed due to the 3/4" to 7/8" shaft diameter change.

Simplicity manufactured the shafts by pre-machining the shafts out of oversized medium carbon round bar, then induction hardened in the area of the needle bearing, then ground to size.

I will see if I can find another one first . 

[Austin 111]

Very good looking tractor David! Good luck getting it up and going, make sure to keep us updated on it.

[David Barkey 23]

Yesterday rebuilt steering mech. new needle bearings . New bushings in the gear and drilled the ears out to 11/16" and made new oversized bushings and new cross bolt . nice and tight now . 

[David Barkey 23]

At some point someone has made some "repairs "  I need to find some measurements ect. to make these right again .  Any pic I can find on this part does no have 2 hole in the centre or these bushings . This is not my first GT restoration , but is the first AC/ Simplicity I have worked on . I have a service manual on order but it is not in yet . If someone can enlighten me , or point me to information I need that would help .Been searching but no luck so far .

Part appears to be part of the hanging PTO:

Above from the B-112 Parts manual - appears a PO has made an "improvement".   Exactly what info/measurements are you seeking?

If you don't want to wait, there are several B series manuals in our "Downloads" forum.  For $10 dues you get access to them all.  For example, the B series Service Manual:

Yes I have been on partstree.com .  I am looking for the dimensions between the centre line of the holes down the length of #15 ( PTO Bracket ) from where the spring hooks on . That way I can repair the "improvements " and ware .  The last picture is what is left of the Rod Guide Assembly / belt guard .  I will need need to make that one from scratch . The only one I have found for sale is on evilbay and looks a little worse for ware .   

Thank you , I will

I just ran out and looked but three out of four Mid-PTO’s have the extra holes.

Thanks for this , I see that the top hole is being used in one bracket and the bottom hole on the other bracket . Does anyone know why ? The manual only show one hole in the  centre of the bracket . I see you have a PTO rod guide/belt cover . Would you be able to take some more pictures with measuring stick so I can reproduce this part .  

Thanks 

[Bill725 1,287]

I compared the 3212V with the small BGB to a 3314V with the big BGB and the following front variable clutch parts are different.

Ref. Description 3212V - 3414V

AM Slide Spacer 164174 - 172205

AN Stop Washer 164175 - Not Used

AP Slide Spacer 164173 - 172204

AK Pulley-Half Assy 164171 - 172214

AL Pulley=Half & Bush Assy 164300 - 172213

Some more progress .

Wow this should be one nice restore when you've completed it, I'd be happy just to find another B 112 little lone restore as your doing

[Austin 111]

@David Barkey it's coming along very nicely. Make sure to keep us updated on it, looks great.

It's a factory hole. If my memory is correct it is for a rear work light.

Appears my memory is fine. It is listed as an option, here is the link from the Club Research area.

Thanks , Panels are all getting stripped blasted ready for paint . 

[David Barkey 23]

Thats most of the parts sand blasted and repaired . Now in base sand out paint . Needs a couple of weeks to cure before sanding .
