FRONT MOUNT HYDRAULICS

I have been the proud owner of a 47 2n front mount for 20 years. During the 20 years I have restored the old girl to excellent condition. I would rather give up my wife and maybe my dogs and guns in order to keep her running. Keeping her running has not been a problem! Convincing my wife that I need to keep taking on new projects with the N is another story. Ihave recently taken on a new one and the wife is probably going to kill me. I was given a Freeman FEL # 114000 in very good condition and one thing led to another. I did not want to run the loader from the on board hydraulics nor did I like not having live hydraulics so I purchased :
1. Cassapa hydraulic pump 6.1 gpm @ 2100 rpm
2. crankshaft pulley with 4 threaded holes from the host of this site
3. Pump drive adaptor 6 spline from the host
4. Pump drive shaft 6 spline x keyed from the host
5 Morflex coupling. ¾ x ¾ from Walts tractor
6. Sun priority flow valve fixed orifice rated 3 gpm
7. Prince hyd cylinders, double acting 36” stroke

My plans are to mount the pump to brackets I have already fabricated to run the loader and use the priority flow valve plumbed to the hyd test port to provide live hydraulics. My first question is how a standard 5/8” nf is bolt modified to be used in place of the hand crank nut to retain the crankshaft pulley. Also is a flat or lock washer needed? Do I need to worry about the crank rope seal leaking after the new pulley is installed? What is the best way to align this type of pump drive?

I am sure I will have more questions as this project evolves and would welcome any advice regarding pros and cons, prior experiences, or any comments from the very wise and helpful members of this board. I am going to tip a few beers out in the shop now and play with the N. Hope to hear from you.

I have a small amount of experience in this matter - I'm in the process of putting together a kit to do this very thing. From the sounds of it you have it pretty much worked out. Take a look at my pics and if you still have unanswered questions fire away - either here or direct to me.

1) just grind the head of the bolt off enuff to clear the drive hub, no washer needed

2)the rope seal should b OK if its not leak'n now

3) just make sure you align the notch on the end of the crank pulley to the key on the crank

4) keep the pump shaft inline with the crank

Enjoyed the photo-tour!

Four 3/8" bolts seen just below the radiator, attach the loader to the front of the tractor. Been like that for 25+ years, never had a problem with the front end.

Pump mount is welded to the loader frame. Pump is 11 gpm from Northern Tool. Two 3/8" bolts just foreward of the pump go down thru slots in the mount to adjust for pump shaft length.

Pump alignment is critical. Shaft will wear out quickly if it hits on the axel pivot. Eventually (2-3 years) the shaft spline will wear out, as it is softer than the spline it goes into. I usually just cut about 3/4" off the end and adjust the pump mount in to compensate.

Neat, live hydraulics with out a pump hanging way out in front of the motor.
Excelent.. Except, on the side mount N's there's a generator there. You making a a kit for the other side also?

If I had a front mount, I'd be wanting a $quote.

Hokie---very clever, neat idea---keep us "snow plowers" posted on your progress.

Yep - that was a big part of the motivation.

Side mount is in the works - looks to be easier thatn the front mount.

So the internal hyraulic pump still functions when the PTO is engaged? It just becomes additive at that point?

Do you have pricing? Very clean installation.

Yes - the internal pump continues to work as it always did. Remember it's not like a modern constant flow pump - it only pumps fluid when the 3pt lever is raised and opens the inlet valve.

I don't have a "hard" price for the belt drive and mounting kit yet but it will be $175-$200.

The hydraulic pump, hoses, and fittings (except for the sump adapter) are all off the shelf items. If you want to buy them from me along with the mounting kit I intend to resell them for exactly what I pay for them - $175.

When I have all the details all wrapped up and a hard quote from the CNC shop for cutting the brackets I'll post a full product description and ordering info on my website. Hopefully that will be "real soon now".

I have a 1941 9N would like to know if this system works for it, also, how about a backhoe, setup? Thanks, new 9N,owner, Doc Beckner Lexington NC

Yes - in fact my tractor shown in the pics is a 41. Backhoes need a big (high volume) pump - can likely be done but requires more components than what's needed for live hydraulics. Interesting application and I'd be interested in working with you to work out the details.

Doc:

The system TOH designed for the front-mount 8N should work on the 9N too.

You asked about the backhoe setup....most of the backhoes I've seen made for the small tractors have a pto-driven pump rather than a pump up front.
