Base tractor for 1957 case industrial TLB

What tractor (farm tractor?) did Case use for a platform tractor to add a backhoe and loader? Axles are flanged. I thought
the platform tractor was a case 300. Ones I have
seen have a keyed axle. Transmission on the 320 is 4 ahead
and back with a shuttle. Additionally there is a high and low
shifter giving 8 speeds ahead and back

The first Case TLB used a 300 round nose utility tractor, non-adjust HD front axle and flanged rear axles. all 300 variations had the option of the 8 speed shuttle, triple range or std 4 speed transmission, the pic is the very first one assembled, there is much more to the story but I will stop here but let me add Case took the market by storm with this machine and still holds the best resale and TLB sales today and have introduced many industry first's, like extend a hoe, hyd self-leveling buckets, over center backhoe design greatly improving roading ability's, they were also first with a torque convertor equipped backhoe with the 420B in 1958

Case Nutty,
Thanks so much for the information. Was the 300 case tractor with solid front axle, flanged rear axle, shuttle with 8 speeds like mine a farm tractor? Case 320 I have haa the 3 point eagle hitch for running 3 point equipment when the backhoe is removed. I used to remove the backhoe to run my bushhog but as through the years we acquired several ford tractors: 8n,ford jubilee which have the 3 point hitches so no need to remove the backhoe. Manual for the tractor says the backhoe is easy to remove and install on the tractor. Always difficult for me. I extended the hydraulic lines to the backhoe which makes is less difficult to install the backhoe. Did you work for case or just like case tractors? Picture you sent is tractor we have.

We had a Case dealership in the 60's and 70's, I have been in all areas with Case units since 1966, ordering, setup/predeliver, selling ordering parts repairing them, I do not even begin to think I know everything about Case but I do know a few things lol. Your 320 is the same exact tractor as any AG dealer could have ordered, they had a base machine for the TLB chassis, but it could have been spec'ed with any number of accessories, eagle hitch,pto,remote hyd all could be added to the base machine, the 320 was sold by Case CE or Industrial dealers, the model 310 TLb was sold through AG dealers,, where the book tells you it is easy to remove the hoe they were telling the truth but they were comparing it to the other backhoe attachments available at the time as some of those took all day or more to remove, I added some shots of the ops manual for the AG units as you can see they even list the utility version like your 320, the AG and CE units are the same tractor 100% powertrain wise, My ops shows the "B" series but is the same exact machine other than the tin work changes

Case Nutty,

Thanks for the pictures of the base tractors for the 320 case. I have never seen the base tractor before.
Removal and assembling the hoe back to the tractor is certainly less time consuming than a day for some backhoes of the day. Takes me about 1/2 hour to remove the hoe,(I extended the lengths of the hydraulic lines connecting the hoe to the tractor. Changed the metal line from the pump to the hoe with a rubber hydraulic line. When I got the 320 it had a loader on it. When I added the backhoe I changed the hydraulic front pump to a 19 gallon per minute pump.

Case Nutty,
Would you check questions I had about replacing the inner seal G13801 on my case 320? I think It is possible that I would need to remove the axle housing take it to a machine shop and have the axle pressed out of the inner bearing, have the outer bearing pressed off then have the machine shop replace both seals and press the two bearings back on the axle shaft

Remove the housing and you can drive the races ans seals out no need to put it in a press, the cones can be a bit harder if you do not have a bearing puller, I have had to carefully split the cone with a torch to remove them trick is to not cut the axle.

Thanks for the reply. Am I correct with the following: Axle housing removed; will need to remove the inside bearing cone prior to the axle coming out of the housing? I have used a torch to cut bearing cones and have also used a grinder with a cutting wheel. A Dremel tool with a small grinder might work better. Risky business due to possible cutting the axle.How would this be done in a machine shop? I know when I have had axle bearings replaced on my ford pickups the machine shop presses the bearings off the axle shafts. Axles on my ford 8N and ford jubilee tractors do not have an inside bearing on the axle shafts. I will proceed with caution with this project. May just let the seal leak a bit as it doesn't get on the disc brakes due to their location on the tractor.My 320 gets used maybe 10 hours a year. Removing a boulder from the field, They seem to grow here in the northwest, hard on the riding lawnmower and bushhog, digging holes for new trees, digging up around a leaking pipe. Age is against me now since I am old like the tractor, 76 years old for me 60 plus years old for the 320. I have kept active all my life so I could take on the project.

Case Nutty,
Thank you for reviewing what I need to do to replace the inside seal. I have cut races with a torch on other axles and additionally have used a grinder with a cutting wheel to cut cones. A risky business due to possible damage to the axle.

Am I correct with the following: Remove the axle housing.2.Need to remove the inside cone bearing in order to be able to pull the axle out of the housing. Drive the race and seal for the inside bearing out of the housing. long piece of round steel for punch. Cut outside cone and remove from axle shaft.Drive outside race out of axle housing. Replace parts in reverse order to install. Would it be
easier, more expensive,to take the axle housing to a machine shop and have the axle pressed out of the inside bearing cone?

Case Nutty,
It seems to me that the 320 I have is much heavier built in the differential and rear axle parts than parts in the differential and axle assemblies on my fords 8n,ford Jubilee,my TE20 Ferguson. Several extra parts for my 320 include an axle which is much heavier build than on my other tractors.Maybe this is why Case chose the tractor to add a backhoe and loader.

Thanks for sharing your interest and knowledge.

all you have to do on the inside bearing is remove the castle nut, then the housing will work back out of the gear and inner bearing race these are not a press fit, Case tractors were always built heavier than most any other brands

Case Nutty

Thank you. Obviously You have worked with this tractor

Case Nutty,
Have the axle housing off with axle inside. The inside bearing is tight on the shaft and I am unable to pull the axle out of the housing.Axle housing will not come off Inner bearing comes up against race which prevents axle shaft from sliding out.

At this point I think I need to carefully cut the inside cone with my torch in order to remove the axle shaft. Once axle shaft is out will cut the outer bearing with my torch or grinder to remove it. You mentioned about using a torch to cut the cones. This sound right way for me to proceed?Should be able to drive the races out once the cones are removed
Thanks Chris

Case Nutty,

You have a collection of case bachkoes and case crawlers? Power steering on my tractor is working good. Another member on the forum told me how he modified a ford power steering cylinder to fit on his 310. Found one at Walt's Tractors. Very expensive so hopefully power steering cylinder on my 320 wili continue working

Case Nutty,

I posted this message earlier today under case loaders, crawlers> Wanted to know: When case decided to use the base tractor-case 300- for addition of a backhoe and loader. Was this tractor designed for the additional weight of the loader and backhoe as regards to differential, brakes, axles, tires, and front end parts? When I got my 320 most of the front end parts: spindles, rear bracket, axle had been broken or welded together. Replaced all the parts with new but did get a good used front axle from Farmland Tractor in Oregon. Tractor seems to work fine with the additional weight of the backhoe and loader.
