Running chipper with hydraulic feed on INTERNATIONAL B414

[Duvie]

I am looking to add hydraulics to run hydraulic feed on pto chipper. Machine used to have a loader and still has loader valves (see pictures). Pressure from hydraulic pump goes to top of loader valves assembly and exits at the bottom of the valves through a quick disconnect, then goes to the port under the seat. The chipper hydraulic feed is open center type so, Can I just disconnect the quick connect at the bottom of the loader valve and feed through the chipper from the valve and back from the chipper to the disconnected hose?

I just picked up two of these B414 diesels and I really like them

You need to find how how many gallons a minute the chipper requires. Then what a b414 does.

The B414 hydraulic pump only has a capacity of 6 Imp or 7.2 US GPM unless it has an external hydraulic pump mounted on the front driven by the crankshaft. So verify the requirements of GPM of the chipper.
PS, someone may have replaced the original B414 hydraulic pump with the larger 10 GPM that was used on the later crate units that were assembled in IH Louisville, KY plant with power steering. A photo of hydraulic pump will identify it.

I have run the chipper on my JD 4100 that has a similar hydraulic flow rate to the B414 so I am not concerned about the flow rate. The hydraulics only drive the feed for the chipper, the pto does all the real work. Just looking for the best way to plumb it.

Good, did I miss the "hydraulic only drives feed rollers" in your original post?
Do you require assistance with connecting the chipper to the existing B414 hydraulics?

Jimb2, yes, I stated that in the first sentence of the post…..lol. I would appreciate some help on how to tie it in. The chipper connected to my John Deere’s power beyond so that makes it an open center type attachment if I understand correctly.

The pump pressure line on the B414 goes to the top of the unused old loader valve and leaves the bottom of the valves through a quick disconnect ,then over to the port under the seat. My thought is that I could just disconnect the disconnect at the bottom of the valves and have it run through the open center chipper , then to the port under the seat.

I just purchased two of these B414 diesels B414’s. One has a loader and the other doesn’t but both have the loader valves. They are both 1962 models.

You have to determine where the hydraulic pressure relief valves are located. There should be one pressure relief valve in the circuit to the chipper.
There is one built into the tractor on that block on the front of the seat. I can't determine if the hydraulic valves from the loader has an inbuilt pressure relief valve or not? Does the feeder control on the chipper have a pressure relief valve?
Do you live in USA or Canada or elsewhere?

Example of Relief valve on loader valves.

JimB2, I am in the northeast USA and I do not see any sign of a pressure release on the loader valve or chipper.

Just looked at my other B414 and the loader valve does have a relief as can be seen on the left side of the valve. This machine has a lot of blow by and is really hard to start. Looks like I may be doing new sleeves and such. She is plumed the same way the other machine is plumbed.

 

[JimB2]

Yes that is a relief valve.
See photo in next post. I believe the hydraulic lines in a loop that I put Red Arrows on are for the loader bucket circuit.
An easy way to connect the chipper would be to disconnect that bucket line at the Quick Coupler that I put the Red Arrows on then connect the chipper hydraulic lines to the Quick Couplers, then by tying IN or OUT the lever for the bucket spool valve for the hydraulic oil to flow in the correct direction to drive the chipper feeder in the correct direction.
PS, to lift the 3Pt, you will have to release the bucket lever spool valve back to Neutral position.
The John Deere may use a different style of hydraulic Quick Couplers.

Thanks JimB2!
