This may help anyone needing to know sizes of bolts connecting loader to the tractor frame.
I sheared off two of the bolts where the loader frame connects to the main frame at the front of the tractor. I can't recall those sizes, but they are straight through with nut so an SAE equivalent will suffice. I didn't think much about it, even after doing it a second time.
Saturday I was using the loader and started hearing a click. I thought not good, must have sheared those front bolts again. Couldn't figure it out. Finally after looking several times noticed a bolt sticking out without a head. Drat.
Realized the bolt sticking out was one that bolted the engine to the frame. That bolt is an M12-1.25x35mm bolt. I picked one up at Advanced Auto.
Also noticed two of the bolts towards the back of the loader frame were missing. Those bolt the loader frame to the tractor frame, and are a M12-1.75x35mm. I picked those up at Tractor Supply. They had been missing since I purchased the tractor and I didn't think much of it.
Well, other than those 2 missing bolts, I just realized where there are 4 other holes about where the oil filter is that were missing. It appears they bolt the loader frame through the tractor frame into the engine. UGH! They haven't been there since I bought the tractor I am sure. No wonder I keep shearing bolts (other than probably overworking the loader). Well, those bolts are a M12-1.25x55mm. I had to order those from Fastenal because no one around here had them. I had to remove one from the other side of the tractor to determine the size.
So, all in all, from back to front (for one side):
M12-1.75x35mm - 4 bolts at back of loader past engine compartment
M12-1.25x55mm - 4 bolts near back of loader near rear of engine
M12-1.25x35mm - 2 bolts near front of engine, actually not supporting loader I don't believe
And then 2 bolts at the front of the loader that go through the loader frame, through the tractor frame, and then have nuts inside the tractor frame.
Hopefully once those 55mm bolts get here I can stop shearing bolts.
Now, if anyone knows the correct torque, especially for the ones that go into the engine, that would be great. Otherwise I have read that for M12 bolts the torque is 85 Nm, so I'll have to go with that.
