Case 30+4 Trencher Backhoe - Need Some Help

RTR

Well-known Member
I just acquired a Case 30+4 Trencher Backhoe that is non-running and we plan to fix and get it back going to use. I would like to find out what year it is and I have the serial numbers but don't know where to look. Can't find anything searching the internet.

I was told it ran and operated great until last year when the housing where the starter mounts got broken...I haven't been able to open the hood and diagnose yet as the trencher chain is being held up with a chain and would have to be let down to get the hood open. I was told it has a Wisconsin gas engine.

My first plan of action is to Find and order service and owners manuals for the machine and engine, then determine what part(s) I need to get it repaired. Then the search will begin...

Can anyone help me out to get the serial number decoded to find the year?
 
R I have a serial number book that list the 30+4 being built from 1970 thru 1984. Get me the serial and they also list two models a standard and a special. I am thinking your is standard with the gas engine. You may have to spend some bucks to get a Wisconsin engine running parts a are pricy.
 
Here are some pictures. I believe one of the serial number tags is for the backhoe attachment and you can also see the model of the backhoe printed on the boom. I was told the model of the unit as a whole is a Case "30+4".

We paid $750 for it, so I feel like we are ok having to spend a little to get it going. I think it'll come in handy for small backhoe jobs and such and if we wanted to fix it and sell it, I think we would be ok. I was told it was used last year and it ran good. A friend of my grandpas down the street actually told us he used it (it belonged to a friend of his). I'm not sure if there is a bellhousing to replace, or if it is the engine, or what. The starter looks to be a Delco Remy type like found on the Farmall Tractors, so it's a large starter. Keep in mind I haven't opened the hood yet so it's all by squinting through the open areas.
 
If I am making my book right it was built in 1984.Starting number for 84 production was 1232741. Good luck and maybe you can get it going.
 
You can look up the machine parts on the CNH online parts catalog,it is not easy to find as it is under Davis,go to the link below,as far as I can recall the starter was mounted to the tin shroud that housed the flywheel,the minus is the flywheel has to come off to get the shroud off,you may be able to weld it in situ.
Nice little machine,good luck.

Thanks so much for the link to the parts manual. I don't see ANYTHING on there listing the starter though. That parts manual seems incomplete because it really doesn't list very much. You think I would need more info on the engine to find out what parts I would need for the starter mounting?
 
(quoted from post at 03:14:37 07/01/14) I forgot to post the Wisconsin link,this is a PDF file and it takes time to load.

I noticed that there are a couple of "Starter Mounting Plates" on eBay for the Wisconsin VH4D Engines. When looking at the parts list you posted for the Wisconsin engine, the only think I see for the starter mounting is the flywheel shroud tin. Hmm.....it sure would be nice if I open it up and find that the part listed on eBay for $15 is all I need. Too bad I'm stuck here at work and can't go investigate.
 
Ok Guys....we managed to get the trencher boom lowered and the hood raised to investigate further. From where the starter is located (left bottom of engine looking in from air cleaner side), we believe the only way to get to the issue and repair it is to pull the engine out of the machine. Here are some pictures of the engine. You can't read the tag on the engine because some genius painted over it. All I know is that it is a Wisconsin 4 cyl.

What do you all think??

Here are some closeups of the starter and a picture showing where it is located. I did remove the air cleaner assembly so I could get a clear view of the problem. It's not the best view, but it is the best I could get without removing the engine from the machine.

Anyone can tell you the right thing to do remove the engine and fit a new cowling but that is what you don't want to hear,I would be welding that up,granted there is no room,tack it in the correct place and remove the starter,then weld and plate it,have a bucket of water handy in case it catches fire,use a low amp melting rod like Euctectic 680 or equivalent,clean off the paint and rust for a good ground,tip,to extend the welding rod a piece of thin steel pipe the bore diameter the same as the electrode end of the rod,squash the end so the rod is a tight fit,other end in the electrode holder,you have an extended rod.
Good luck

Fit a new cowling? What do you mean by that. I realize we need to remove the engine to access the area, but it is hard to tell what is broken. Will we need to find a new engine block? I have seen starter mounting plates for this engine on eBay. What are those? Is that what we need? Would be real nice to have a SERVICE MANUAL for this machine. I have only found the Owner's Manual and it doesn't help.
 
The cowling is the piece that is cracked up,it houses the flywheel,it is not part of the block,the job of that housing is to direct the air generated by the flywheel around the engine to keep it cool and to carry the starter motor,if you can't weld it in situ there is only one way left to go,remove the engine and repair/replace the shroud.

Thanks so much. It is just so tight in there we will be removing the engine. Would you happen to know what model Wisconsin engine this one has? The engine tag info has been painted over.
 

So....I guess it is safe to say that we need a new cowl for the engine so the starter will bolt up. If that's the part, then I guess Before we pull the motor we can go ahead and start looking for the part we need. Something tells me it's gonna be hard to find.

Does anyone know where I might find a cowl for this motor? Used or New (if available) is ok with me.
 
Be careful with what you buy, a cowl is different from a cowling. Websters says the 2nd def. of a cowl is a hood shaped part or structure and a cowling is a metal covering for an aircraft engine, etc. I associate a cowl with a firewall of a car not a part a starter would bolt to.
