Gear Box Gone In Blower on F2100

[DandW2100]

Hi
I have an F2100 with a blower on the front. I purchased the unit used and it did need some TLC. When I got it there was no oil in the gearbox on the blower and it seemed like it had some slop to me. I got it to hold oil and it seemed better until today when the gear box gave up. It makes a terrible racket and has a lot of slack now.

Like I said I bought the unit used so I don't know what model of blower is on it and I don't see any markings or numbers anywhere. I'm sure it will prove difficult to find parts for. I have never taken one of these apart before and I am not sure if the whole box needs replaced or if it can be rebuilt with new gears etc but, either way I need to be able to identify which parts I need. Anyone had any experience with this ?

Any assistance with this would be appreciated.

You might be helped to identify your snow blower by looking at the online illustrated parts.
https://apps.kubotausa.com/illustrated-parts/

Click on ‘View Illustrated Parts’

Click on ‘I accept the Term and Conditions’ BOX then click on ‘open’

Enter your model – click on search

Click ‘OPEN’ next to your exact model or for Attachments click on ‘Local Options’

Parts list and diagrams will open in a new window

If you go to the Kubota parts website and click on illustrated parts list. Then agree to their terms. Next screen put in Model F2100.
when it comes up click on "local options" you will get a list of all the attachments sold for that model. I checked and it has a number of different front mount snow blowers. Perhaps you can look at the parts diagrams and get an idea of the model of the

snow blower that you have.

Tthorkill beat me to it.

I can't get on that site. I am in Canada and it won't let me access it. I tried the Canadian site and it's not the same.

I poked around and you are not going to like what I learned.
Possible blower models are B281 and B2782.

Both blowers use the same gear box

The exploded parts illustration below shows the two brass gears #200 but no part number nor price just the price for the complete gearbox.
$1,003.00

I then went to the Messicks site and searched for the blower there. B2781

From the Messicks site I was able to find part number for the two matched gears and went back to the Canadian Kubota site with that part number.

In Canada the matched gears are $771 while the complete box is $1,003

There is also a shim kit needed and this gives you fair warning that setting up the gear box after disassembly is not for a novice.

This gear box is not going to be unique to Kubota but finding the correct one at a much lower price may be a bit of a treasure hunt.

Thank you so much for all the information. I am beginning think that the blower is either not a Kubota or some different model. The gearbox on mine looks nothing like the diagrams shown. These all seem to be beefier than the one I have. The gearbox on my machine doesn't look any different then the gearbox on my Cub Cadet walk behind.

I will go out when I get home in about an hour and grab a picture of mine, perhaps it might shed some light on things. This is the worst about buying used... you never know.

Here are a couple of

pictures...

Give me a close up picture of the label on the right please.

 

[DandW2100]

Here is a picture of the label. It has to do with shear pins. I am pretty sure this is not a Kubota blower but, trying to figure out the make and model may be a treat, maybe a briggs and stratton or something like that. Had a closer look when I took this picture. Looks like where the impeller and gearbox rods meet( square metal pieces in the picture) might be welded together... oh no !!

 

[kubotasam]

The two "square metal pieces" that you referenced welding together. Don't weld them!!
That is where the shear bolt goes to protect the drive line when the impeller gets jammed with a rock or stick and can't move.
The shear bolt goes through the small hole in both sides and holds them together transferring power until it shears and stops the power.

I wasn't going to weld them, I believe they are welded by the previous owner because I don't see any pins in them at all. And, it looks like some weld to me.

I also started to remove some of the auger system to see if I could see how difficult it is going to be to come apart. I don't know if the gearbox is actually the problem. The bearing where the shaft behind the fan comes thru the frame is pretty much gone. The shaft flops around in there with no support at all. I assume that's whats making all the noise. So, I guess now I need to take the blower off the front so I can stand it up and get at that bearing some how. Have to take the bottom sprocket off and slide the whole auger system out ?
Then the fun will begin finding a replacement bearing, seeing as I still don't know make and model. To add to the fun, we are still in total lock down here due to COVID and can't get into any stores or businesses that are not deemed essential !! AND it's snowing like crazy

Remember there is a chain reduction assembly on the back side of these blowers to lower the fan rpm down to around 540 from the mid pto speed of 2,000 +. Problems arise with the chain and sprockets coming loose.

Sorry I guess I did not read careful enough about the weld.

As far as the bearing between the top gear and the impeller. They are usually a standard "spherical insert bearing". Measure diameter of shaft and you should be able to source one from amazon or Ebay.

A simple bearing that kubotasam pointed out would be a great and simple (read cheap) fix... that would be outstanding!

Dave_eng and kubotasam may have better suggestions, but your blower looks very similar to my BX2750D blower, much like the B models Dave pointed out.

If I remember correctly, my blower may be a RadTech blower from Canada?

EN – RAD Technologies Inc. – RAD Technologies Inc.

Maybe the B2781 and B2782 blowers are also RadTech blowers, and maybe the Briggs & Stratton reference may be a re-brand of a RadTech blower?

Seems they provide OEM equipment for many manufacturers....

Just trying to help..

I don't see a reduction assembly on the back. Looks like the fan shaft goes into a bearing ( doesn't look to be all there anymore) and then to the sprocket. But, as I mentioned before, I am beginning to believe that this blower is not a Kubota. Still don't know the make and model but I am looking... could be Simplicity, Briggs and Sratton, Snapper, etc. Does it look familiar to anyone ?

As I start to disassemble I will post more pictures... thanks everyone .

Yes, I believe you are correct. But, I haven't got it apart yet. I have to remove the blower from the front and turn it up so I can get at whats left of the bearing. Then I should hopefully be able to remove it and try to match it up. I will post pictures as I find more out... Thank you.

That blower assembly is identical to a Massey Ferguson M50 (I think) blower that I purchased used from an equipment dealer in Waterdown Ont. about ten years ago. It was only the blower housing with impeller and auger assembly plus the chain reduction on the rear. After I completed the required mount to my Kubota I came across a sales brochure from when I bought the tractor in 1985. It showed a front mount snow blower as an available attachment. To my amazement the auger assembly was identical to what I had purchased. Having said this I would have to agree that this is not a Kubota unit but possibly one that is manufactured by one supplier for multiple customers.
With regard to the small plates on the shaft, I just use a standard 1/4-20 fully threaded bolt as a shear pin to protect the drive for when I get a stone caught by the discharge impeller. I always carry spares and wrenches to replace. Lots of stones on my 4000 foot driveway so I have used a few of them.
Although the blower when I purchased it showed very little use, The seals on the gearbox have always leaked a bit so I check it before every use. I figured it would be a pain to replace the seals but certainly will if they get worse.

Any chance you've got a PrincessAuto nearby ? They have a very good selection of bearings !
The there's any more labels' post them,hopefully a 'part number' will show up...

If the bearing on the blower impeller is gone, it'll rattle terrible ! I've replaced several on walkbehinds ove rthe years.

 

[DandW2100]

I do have a Princess Auto near by but, Don't know if they will carry this type of bearing and triangle housing...
I can't find any blowers that look like mine by looking for the Massey Ferguson M50..

I think I have found that it might be a Simplicity 1691360. I did a lot of looking around by looking for the shear bolts specified in the only sticker on the blower. They are listed as Murray, Snapper, Simplicity. I looked all through the different groups for 46" blowers and the one I found that looks like mine is the one mentioned above. It uses both shear pins and seems to be the only one that does, so far. The only issue is, there are two different bearings and housings depending on what range the serial numbers fall into. Still a problem because I can't locate the serial number anywhere. I guess I will try and get it apart and see if I can identify the parts that way. Its no good the way it is !!

I usually remove the defective bearings and take them to an industrial supplier like BDI. I think the closest one to you is over an hour away in Severn but you might have a similar supplier locally. They just measure the old one and give you a match. On a rare occasion they are unique requiring you to go to the dealer who usually only go by part numbers. I generally get all my belts from these folks as well as they are frequently more economical than a farm equipment dealer. I would certainly call them first to see if they will sell to the general public and what other restrictions would be regarding covid.
I am going to the farm tomorrow and will verify the model number of the Massey Ferguson blower housing that I have.
