"Hokie Hydraulics" - fluid power for the N-series

While there's still a few final touches to be completed the first prototype of my auxiliary hydraulics add-on for the N-series is nearly complete. This prototype will be headed North to JoeT's place for a thorough field test. Assuming all goes well I expect to be shipping production kits by the end of the year. This is the real deal - modular expandable live hydraulics at an affordable price with plenty of muscle to run 10+ GPM @ 3000PSI remotes with appropriate add-ons. No need to tie up your PTO with a pump for high volume applications. A version for side distributor tractors will be available as soon as I find someone with a side mount who wants to help work out the geometry in exchange for special (e.g. below cost) pricing. :roll:

Final pricing is still up in the air - I' have to get a quote on laser cutting nice professional looking mounting brackets - but I expect the price for everything you see in these pics - a complete live hydraulics conversion - to be ~$375. The belt drive with mounting bracket and industry standard SAE pump mounting foot will be available ala carte for those who want to roll their own using components (pumps, hose, fittings, etc) they already have - roughly $175. If you want to try to make one from scratch I'll [u:480c5d3119][b:480c5d3119]give[/b:480c5d3119][/u:480c5d3119] you the shop drawings - you will be extremely hard pressed to match that price :lol:
Here's a link to additional pictures of the prototype on my 9N: Hokie Hydraulics Photo Album

The tooth type belt should work very well till it eats the teeth. I have rigged up set ups like that over the years and have always used the normal v-belts and they worked ok but a tooth type belt should be at least twice as good

Any reason to speak of as to why it would eat the teeth?

The Gates design manual rates that belt/pulley combo for continuous use to 30+ HP - it's the same technology Harley Davisdon uses on their motorcycles albeit a bit smaller pitch. Load it up enough and I'm pretty sure you'll stall the N motor out before you strip any teeth off the belt :roll:

Misalignment concerns are what will eat the notched belt up,,, it will try and walk its self straight,,, strength is not the question its alignment,,, I spec you built some adjustment into the pump pulley,,, long as its parallel to the crank all should B OK,,, The adjuster mite B the weak link,,, I would have built it smooth and make the pump pulley with the belt retainer made into it,,, whit the present set up there's no room for error,,, just my thoughts,,, you look'n good

The pump mounting foot and idler are both adjustable fore/aft and in/out for that very reason. That idler is a mockup - the real deal is a little larger, runs on a pair of R8 ball bearings, and is mounted on a 1/2 stud. The mounting bracket will also have a strut added over to the block to stiffen it and prevent flexing. Production brackest will be laser cut from 5/16 plate - that one is 3/16 cause I'm a wimp with a grinder and cutoff wheel. And to be double triple sure I intend to add flanges to both timing pulleys. It should be quite simple to get the belt running dead true.

PS - your screw will ship Monday morning.
 

You don't really expect for Joe the back yard jack of all trades to really know how to line up a notched belt do ya,,,, I spec thats why Zanes V-belt set up has survived,,, it can with stand B-N a little off,,, its just 2 simple,,, I know you have considered flex and all that chit by look'n at the brackets,,, its folks that will not take the time to set up the notched set up thats gonna drive ya crazy,,, ell thay can not read a compression gauge and cipher out what its tell'n ya, very few here can ,,, set'n up a belt will b rocket science,,, well I know you did the best job possible,,, its the hands you put it in. :wink:
 
TOH - I'm in big time. I already have one of your sleeve puller outfits and if this setup is half as well made then it's the stuff. That price is awesome BTW. Put me down for production kit #1.
