Good morning guys. So I just bought this case backhoe. I got some ideas on what it might be from another forum. 310b or a 420b. Thing is great starts right up does everything I need. I need a power steering pump. I have a guy trying to rebuild the original pump but it s been a couple weeks and not sure if it s gonna happen. So any help in identifying this backhoe and where I can find parts would be greatly appreciated.

Bro told you on your previous post that you have a 420B The lever on the RH side of
dash locks up the torque converter drive. A 310B did not have torque converter drive.-

Does the pwr steering pump need to be rebuilt($249.0 rebuilds available) or do you need to replace the paper filter that is more than likely clogged . Filters available from Saeli 315-585-9826. CM

Apologize but just getting opinions. Not trying to $&@@ people off. Thanks and I looked into the power steering pump. What would be the best site to get parts from. This is my first machine and have no clue and am learning. Gotta find where the filter is located and yes the pump is shot. Where can I find a rebuilt one
 
Well, guess what I already told you EXACTLY what it was so you now have yourself to thank for what I am saying next, I am DONE helping on this site I am sick and tired of putting out the correct info to someone who acts like you enjoy your purchase
 
If you have a belt drive PS pump, the filter element is in the reservoir mounted on the valve cover. If gear drive PS pump mounted on the right side of the engine, there is no filter.

The s/n in your pic is for the BH not the tractor.

Get your !!!!! out of a bunch.
I have a backhoe I bought, new to this whole backhoe world looking for parts and info and any help I can get to get this thing up and running again I appreciate it. In the other forum I was told to head over to this forum to get more info and that s what I m doing. Thank you and stay off the post if u can t handle the things I ask other people s opinions or if your going to be a lil

When a long time member with 14K posts, who was a Case dealer, who sold tractors like yours gives you info, I wouldn't crap in his Wheaties. I realize it takes noobies a while to get the hang of his place, but he was doing his best to help you out. You are going to want to contact another long time poster here- John Saeli of external_link. http://external_link.com He's another long time dealer that knows more about these old girls than we ever will. You will get help here, but posting the same question after having the rig ID'd comes off as rude or like you don't believe the guy who gave you the straight scoop. Just calm down, get a manual for a Case 420B off Ebay, here's a link to the one I bought earlier this year- https://www.ebay.com/itm/Case-420B-420-B-Industrial-Wheel-Tractor-Owners-Operators-and-Service-Manual-/300707164193?hash=item46038b3021

That will get you started.

420B PS pump is item #52 p/n G45157 at the first link. That is a common pump to several models of early Case tractors. You are not going to find the exact pump other than used. All States Ag Parts, as well as probably others, is selling a universal PS pump that they list as a replacement for p/n G45157 as well as other p/n pumps. I haven't bought one from them so I can not advise as to suitability.

If you buy one of these universal pumps compare it with your existing pump for housing fit and most important that the drive gear is the same type (helical), same diameter, same nr of teeth and positioned the same as your existing pump gear relative to mesh with your cam gear that will be driving the pump.

Be advised that these old tractors with the this PS system that has the cylinder mounted in front of the axle is not true power steering, it is billed as power assist steering. It is most effective when the tractor is traveling and at higher throttle. At full speed the original new pump was rated 6 GPM @ 1000 psi.

Please remember CNT that there are many on this site that appreciate your advice and knowledge, even if a few may ignore you. If I see your handle on a post I am always sure to read it, even if I do not own that particular tractor. We also appreciate your pictures, and look forward to them!

Thanks that is awesome. Did u ever have a problem with any pump seeing as the original pump uses a bracket and the starter mounts to the ps pump.

I don't understand what you are referring to???

Joe, the only possible thing he could mean is the Generator mounts to the PS pump!
 
(quoted from post at 07:56:37 08/05/19) Joe, the only possible thing he could mean is the Generator mounts to the PS pump!


That s exactly what I mean. I had a problem with the start I thought it was the starter/generator it ended up being a wiring issue but I can t check if the starter problem was fixed because I have someone trying to rebuild the PS pump and can t mount the starter. Just wondering if anyone had a problem with buying the PS pump and having to have to fabricate something to mount the generator/starter.
 
Read mEl's post, does you're PS pump piggy-back a generator, if not is your generator belt driven on the left side of the engine?

If there is anything piggy-back driven off the PS pump it can't be the PS pump I linked to in the 420B CaseIH parts list or the one on Amazon that I linked.

Is not your starter located as in my pic of a similar 310 utility engine? Can you post a pic of your engine right side?

Joe

Ok, I can see how the generator is mounted to the top of the PS pump at the link. That was a configuration for diesel engine with separate belt drive PS pump mounted top front of the engine. Obviously an option for gas engine also see the link.

By the looks of the generator mounting bracket it appears to bolt to the PS pump casing in front of the reservoir. If that is the case then the PS pump listed in the CaseIH 420B parts list p/n G45157 is probably the correct pump.

This just points up the value of having long time experienced Case people like CNT, mEl, Loren, and others participating on this form.

Another thought, the fill pipe on the universal PS pump appears to be offset from the top but hard to tell from pic if it will interfere with the generator mounting. The generator bracket may mount far enough forward to clear the pipe. You may be able to determine that from the existing pump.

Sorry I was wrong the starter is not mounted to the ps pump. I m guessing it s the generator. It connects to a belt for the fan. And yes the ps pump goes on then this metal bracket bolts to the ps pump then the generator mounts to the ps pump. I ordered the pump had to get from Alabama hopefully I will get it in a couple days. It s an exact aftermarket replacement pump. Hopefully it works with no problems.

I m new to this and trying to figure it out and all your help is greatly appreciated. And thanks for helping identifying the backhoe. Just got the tank back cleaned and painted bout to mount that and make connections new ignition oil filter and plugs hopefully get this thing to work on the yard.
 
When you get the new pump all mounted up and operational, you still may not have power
assist. The valving for the steering cylinder is located in the cylinder head and
controlled by the steering linkage. I have seen far more problems with the control
valve than pumps.-------Loren
 
Joe, don't forget to give yourself a pat on the back also.
It gets frustrating when people come on here with little to no knowledge of what they have and then question what we tell them, and they have done no testing or anything to diagnose the problem before throwing new part at the thing and wonder why it doesn't work yet.----Loren
 
Good to know, I hadn't seen that PS pump/generator setup before. Good thing mEl gave me that kick in the butt, LOL. Normally utility tractors have factory belt drive PS pumps and the gear drive pump is usually factory on general purpose (ag) tractors but there are factory options and they can get swapped in later years. The 310 pic above is one I swapped from belt drive pump to gear drive.

Loren is correct, the cylinder is much more problematic than the pump. Aside from moisture damage, piston binding from dented ram housing, the control valve bore/spool gets scored from debris in the oil and seals leak, the control valve actuator assembly frequently is not adequately greased and is not water tight. Most of the posts on here seem to be people replacing control valve seals and not reassembling the cylinder correctly.

Joe
 
Yeah Loren it tends to get a little irritating sometime but I spent 20 years as C/E sailing with some licensed marine assistant engineers that had college smart sheets and about as much engineering expertise as God gave a goose so I am pretty much use to it. I am willing to help as long as they pay attention and try to get it right.

Yea great job joe. The pump was shot trying a new one if that doesn t work I will go from there. And yea I used the information u guys gave me and it has all panned out so thank you. Maybe one day I will know half of what u guys know. Thanks again
 
Those of us with Case equipment greatly appreciate the information from the real Case mechanics on this forum. I hope those without enough knowledge to understand how much you old Case guys contribute do not discourage you from helping those of us who do appreciate it.
 
Is it possible that the engine came from a 600 combine. I have an engine from a 660 that has a similar bracket but with the 660 being a 1966 model it had an alternator mounted there.
