Tool Help needed

[Fred from MO]

Anyone know where a guy can buy a short open ended 1" wrench with a 3/4 drive attachment on the other end for a torque wrench to fit on. I want to torque down the block to crankcase bolt that goes in the window opening on the side of the frame (see square hole in frame on picture). JD manual shows what looks like an open ended wrench with a 3/4 drive hole in it. I don't think a Crows foot attachement would be long enough to stick far enough out of the window to attache the head of a torque wrench. I thought about buying an el cheapo wrench then welding a drive socket to one end, but my friends telling me the chrome plating wont take a weld and it would break under 200ft-lbs that the bolt needs (or somewhere around that torque??)

Just a thought. Stand on a bath room scales while tightening with a box end wrench.

Try the Snap on catalogue. Also, ask on the john Deere forum.

I would be surprised if many people use a torque wrench on these. Just get them good and tight. Definitely use one on the head though.

 

[Aaron Halfmann]

if you grind the chrome plating of you can weld it. I have made my own custom deep well sockets by cuting a socket in half and welding a piece of pipe in the center. Never had one break yet Just grind chrome off first

I would just tighten them down good and tight. Just do it in a manner in which you would a set of head bolts by alternating side to side and up and down.
Or by going center top and bottom then next to the right top and bottom then to the left top and bottom.

Just a thought but I usually split the tractor since this is fairly easy on an old JD. Then the bolts aren"t hard to get to. I made a pipe stand to hold the front part with outriggers. I used it on a case vac, JD B, JD H, and a JD A. I support the back with wood and use a motorcycle hydraulic jack to support the crankcase at the initial split an when I rejoin. It really is easy.

Your friend doesn't know what he's talking about. What do think is in stainless steel? Under a 10,000 deg. arc most of the chrome will vaporize since it's only a very thin coating. You might want to use a 309 or 312 stainless rod to weld on the wrench though. Sockets and wrenches have been welded many times and 200 ft. lbs. isn't really that much. You need to find a chart to figure out the proper torque using your home made extension. I think someone posted one on here a couple years ago.

The ideal thing would be a interchangeable head torque wrench such as this Sturtevant Richmont CCM series

With a box end head attached to is such this one.........

I know this would be a stretch, but as I said, this would be the ideal situation. Personally I would use a good sturdy box end and cut it and weld a 1/2 drive socket or similar to it. Need to TIG weld it and if you use a good wrench and socket it will hold up fine. Make it long enough that you can put the torque wrench 90 degrees to your adapter and still be able to get full swing out of the torque wrench and you won't have to do any calculations.

Anything other than 90 to the side and you will need to do calculations for the adapter length and offset.

Will a swivel socket not work?

I saw some of those type of wrenches in the tool room at the JD dealer I worked at years ago. They looked like they were OTC made for JD if I remember right.

 

[greygoat]

MAC or Snap-On

nope no room

 

[Fred from MO]

Thanks lots of good ideas to try!!

 

[Mike M]

Your going to need a box end to hold that kinda torque.

I like the bathroom scales idea ! Wish I'd thought of it.

I would just hook two box wrenches over each other and I had a good feel for those type of things you can't reach with sockets.

 

[JF in MI]

Son of a beezer! That could actually work! (All the angles would have to be perfect) Excellent!

 

[JDseller]

I have done a lot of these and never used anything but an offset box end wrench. On a 18 inch wrench you only have to pull 125 lbs to have them as tight as they need to be.
