How to pull auger drive shaft for Hobart 4346 mixer-grinder?

Need to replace bearings and seals on the gearbox shaft which drives the hopper auger. Have opened the cast gearbox and removed the hopper but can't figure out how to pull the shaft (with large drive gear) out of the hopper side of the gearbox casing.

    I'll answer this question myself since we figured out the problem later in the day. The shaft consists of two parts (which we knew), and they should just pull apart easily. What we didn't know was that the clutch mechanism which connects the two shafts was frozen and wouldn't release even with the use of a gear puller (broke the cast iron drive gear figuring that out...oops). Once you have the gear housing open the large cast gear and shaft assembly should pull straight back, and then you can access the snap ring on the remaining shaft section which can then be removed through the hopper. We eventually figured out that we could loosen the clutch by locking the gear to the housing with a c-clamp, and then using a box end wrench with a pipe over the handle for leverage, on the auger drive end to turn the shaft until it loosened enough to pull. The clutch is supposed to let the drive shaft turn freely in one direction...ours was locked in place. Once the large the large gear was pulled off, the rest was easy.

The oil seal is the resistance you feel. take a soft mallet or hammer with a soft drift and gently but firmly tap the stub shaft and it will drive out the oil seal in the hopper direction.The lower skirt of the tapered bearing is what contacts the seal so go slow.
Worked for me.

yes the cast can be welded(brazed). if you are able to weld this yourself, just remember before you can weld it, you have to heat it till it is cherry red then you can weld the piece. if your not qualified to weld it you can usually find a portable welding company to do this for you. hope this helps you please rate the solution...thanks

Large Hobart mixer, leaking oil?


* Model? Check side plate or post picture so I can check.
* Usually leaks are at the bearing seal(s). Replace.
* Frequent seal changes (less than 1-3 months). Replace bearings and seals.
* Check shaft near bearing seals for pitting (rust) that will damage seal. Remove and have a machine shop refurbish part. If possible; replace whole part and bearings. (or rebuild gear box.)
* Call your Hobart service rep for a quote.
* Check and replace lost oil as needed until machine is rejected (inspector, quality control, maintenance, etc.) Be careful oil does not get into food product.

I can't get the main shaft out of an A200 Hobart Mixer to service the lower bearing. Any advice?


Honestly, get someone in that knows Hobart mixers. The a200 is an amazing machine, but you will need to strip the entire gearbox apart to get to the bearings. Take this from someone who works for Hobart :)

Need to adjust clutch on hobart 4346 meat grinder how do you do it?


On the 4346 mixer/grinder the clutch can't be adjusted. It is a Moorse clutch and will need to be replaced. If you ate handy buy the rebuild kit for the bottom end from Hobart. It's not cheap but once it's done it will last for years. Hope this helps, Food luck

HOW CAN I GET OUT THE AGITATOR PIN IN ORDER FOR ME TO REPLACE THE OIL SEAL


Punch and hammer. It's best to remove the planetary so you can support the shaft while driving it out. If not it puts a lot of unnecessary stress on the bearings and other parts.

Hobart A200 mixer motor worm gear


sometimes you read of other problems and solutions and it puts you at the edge of your seat. in this case of changing the worm gear on the A200F was cake. when you drop the lower end (3/4 acorn and jam nut), pull out yoke (speed select handle) the center transmision shaft and gears pull right out.worm gear easy to change at this point. if you can change a motor bearing, then you can do this job. Note: change seals and bearings as needed,check all gears,keys and spacers for wear and if you go the mile take gears off drive gears, these are the 2 smaller trans shafts put in lath if you have accsess to one if not roll shafts on flat surface to see that shafts have no bends in them. Also remember when you put the bottom back do not over tighten the jam nut,hold and lock acorn nut, should spin free and have about .016 to .030 movement up or down. Lay out all part on cardboard the way they came out. should go back together easy.

Oil seal


1. Remove the acorn nut, hex nut, and washer that hold the "planetary" agitator section on the transmission shaft.
2. Remove the trim ring (if any) around the same.
3. The agitator section should now be able to be worked free.
4. Remove the retainer clip on the top of the agitator shaft. (Some models have a pair of hex nuts here; if so, remove those.)
5. Pry the gear up and off the shaft. Remove the square key from the shaft keyway at the same time.
6. Tap gently on the top of the agitator shaft to drive it out from the bearings and grease seal.
7. Recommend removing and replacing the top bearing at this time; it's inexpensive to replace, if you're in this deep.
8. Use a suitable diameter piece of round steel stock to drive out the lower bearing and oil seal. I don't recommend using the agitator shaft.
9. Clean thoroughly, insert a new bottom bearing and oil seal, drive in place with a rubber mallet.
10. Replace agitator shaft through oil seal and bearing, tap gently into place.
11. Fill cavity with approved lubricant. I use USP-grade mineral oil, as it is food-safe and provides satisfactory lubricity.
11. Install top bearing, tap gently into place.
12. Reverse steps 5-1 to reassemble.
