Draw bar bolt size / pto pump bracket

[MikeRW]

Just bought a log splitter with pto pump. I attached the pto pump to my 8N and split some logs i've been unable to split with my maul without issue. Had the pto running about 3/4 throttle. The pump i had just sitting on the pto with a chain attached to one of the lift arms to keep it from spinning or sliding off. what i'd like to do is to build a pump mount using the Draw Bar bolt holes on the underside of the rear end. I'd like to get the bolts today but i forgot to size them. I'm at work and if someone knows the size and lenth of the bolt hole i'd appreciate the info. Also, if anyone else has fabricated a pto pump bracket i'd appreciate any ideas. Its a prince style pto pump. Thanks for any info or ideas.

The bolt holes under the housing that a swinging drawbar brckt would bolt to are 5/8".

Mike,
I mounted a trailer receiver to the swinging draw bar bolt holes under my tractor to accept a mount for a PTO pump. The extra supports in the picture are for a backhoe that mounts to the tractor. You would only need a receiver welded to a flat plate and bolted to the tractor. The 2" receiver is just wide enough that I had a relief machined out in the side of the receiver at each bolt hole, then used cap screws because the head is slightly smaller than hex bolts. As the PTO pump mount slides into the receiver the splines of the pump mate with the PTO shaft and a regular receiver pin locks it into place.

Hey nice catch you are rite give that man a cigar.

Draw bar bolts under the diffi the original plate used for the draw bar pin were the bolt goes threw is 3/4" thick. The bolt used to retain it is 5/8" X 1 13/16" course thread. Remember it has a lock washer that's 3/16" thick. That leaves about 7/8" of threads once the bolt is fitted with a lock washer and threw the plate.
To B safe make a dry run with out the plate to find the correct bolt. If 2 long a bolt is used it will pop the casting and you will have a direct hole rite into the diffi fluid. Makes for a rite nice oil leak. I would not want to have more than 3/4" of treads that go into the diffie housing. Make sure the bolt holes are clean of any obstruction. The OEM length bolt with a lock washer will only work if the plate used is 7/8" thick, adjust to the plate used and figger 3/4" of treads are less threw the plate. Nice werk "murn ga"
