Need BD Help - and ? for Walter Hudson

[Orangeman]

Hi Guys:  I stumbled upon a BD this morning that is whole and complete machine.  I talked with the owner who wants scrap price for the machine.  Has a blade on front and pto on back.  Would appreciate your advisement on the following:

1.  Where should I be looking for the serial number on this machine.

2.  Are there vendors that still provide parts for the diesel engine in the event that I need to go through the block.

3. On the steering clutches - do they run in oil or are they dry?  Are the steering clutch plates still available. 

4. Walter what does the SH stand for on a BDSH?

There appears to be an A sitting next to it that has a nice 4 cyl. hercules in it. I thought all the A's has six cylinder engines.

Hope you guys are staying cool.  Thanks for any input.  Orangeman

1) the serial number plate should be on the engine side of the firewall on the opposite side of the aircleaner.
2)Zimmerman Oliver Cletrac and others in the classified section
3)There are no clutches.  It has controlled differiential steering, only gears and brake bands which run in oil.
4)Never heard of a BDSH, only a BGSH.  The S then was for Studebaker who made the engine ( or that what is thought, Studebaker used that engine in 6x6 trucks during the war and it is though that they sold surplus engines to Oliver after the war).  The H is for hillside model or wide gauge.
5) the A model was originally made with the Hercules OOC gas engine or DOOC diesel engine.  During the war the OOC was not available so they used the Coninental 226 6 cylinder engine of the same displacement.

Serial number is on the firewall. The engine parts are getting fairly hard to get, but are still availible. Cletracs don't have steering plates. Just brakes that run in oil. They are availible and very reasonable priced. Easy to change also. If ita a BD, there shouldn't be an SH on it, maybe an H for Hillside, but...

The S on a BGS stands for Studebaker. After WW2 Hercules had an excss of JXC engines laying around. So they made Cletrac a deal on them. The engines for the Studebaker trucks had some extra bosses and were balanced for higher RPMs. The S designated this difference.

As had OOC hercules in then which were a 4 cylinder. They also had a DOOC, which is a 4 cylinder diesel.

Well while I was typing this, Robert beat me to the punch! Well you're getting my copy anyway! LOL

Hello Bob and Robert: You guys are sure a wealth of information, and I certainly do appreciate the guidance and advise.  Is the six cylinder hercules in the BD referred to as the JX series of engines? 

I guess I should have figured that the differential is planetary and thus the brakes operate in oil similar to the little HG.

One more question if you don't mind, when talking with the owner he mentioned that the machine would lock up in one of the gears.  I am working up a cost estimate to get this machine back to working order so need your advice on the transmission.  Should I be thinking this is a gear issue, syncronizer issue or should I be thinking about something else.

My main goal for this machine is to save this vintage American Iron from being scrapped and to use it here on the farm to move some small piles of loam and keep it in good working order. 

Thanks again for your previous replies!

OK, first off, a BD is a diesel and BG a gas.  A BD would have a DJXC or DJXD, a BG would have a JXC or JXD. Later models used the larger engines.  Do you have a gas or diesel??

The transmission is a sliding gear type. All gears are straight spur gears.  If it locks up in one gear I would expect there is a problem with the shift rails and it is going into two gears at the same time. That should be a relatively easy thing to fix.  If you have broken gears that need to be change that is a lot of work. The top transmission shaft comes out the front into the clutch housing.  The bottom shaft goes out the back into the diff area, so the diff has to come out as well.  You can work from the clutch housing with the engine in place if you like working hanging by your feet!!  Other wise the engine needs to be removed.
I have done all this on my DG so I know what it takes!!
You can take the transmission cover off and have a look inside and see what is wrong. That is an easy job.  Zimmermans may have parts.

Hello Robert:   

Thanks for the insights into the engine and the transmission.  I guess I will proceed to see if I can secure an original service manual for the BD crawler.  Do you know if White offered a manual on the JXC or JXD engine.  I was thinking they would since they offered on for the IXK and IXB engines. 

Thanks guys for your responses, I will keep you posted as I progress on this project.  Orangeman

If you have a JXC or JXD engine you have a BG as those engines are GAS!
An Oliver manual for a BG would have a section on the engine.  They often appear on E-Bay, originals are better than copies!

The Oliver Cletrac books are very thorough on engines as well as everything else. They are very helpful. I have done the trans in an A and it wasn;t too difficult, but, it was just a trans housing I was working on with no tracks or engine in it...
