how to you replace snapper tube brake

Hello, I have a snapper snowblower model number I4233 serial number 55077757. I need to replace the tube brake. Has anybody ever done this? How in the world do you get in there to change this thing? I think I have to take the whole thing apart. Thanks I am stumped.

Well, for the life of me, I've scoured over the various diagrams, and I'm not seeing the tube brake.

If you can narrow it down the specific diagram, and number of the part, I think it might help folks offer some assistance.

Here's a link to the diagrams:

Lawn Mower Parts, Small Engine Parts & Much More! | PartsTree.com - Briggs, MTD, Toro, Cub Cadet, Husqvarna, Troy-bilt...

Garage:
MTD....2 stage(modern 8.5 HP) not my favorite
Honda HS622 TA-B - acquired at an auction- nice machine for it's size.
Toro S-140- Picked it up on trash day... it runs, sort of.
Yamaha YS 240 TB "Ricky" latest Craigslist find- on the bench now.

Found it under clutch system parts. It is item # 28 and appears to be a piece of rubber hose? Part # 29 is a cotter pin and maybe removing that will help move the arm???

Thanks to db for finding the parts list.

Experience is something you don't get until just after you need it.

Even with the top pulley out its hard to get to. I took the back off can't get in there that way. I think I am going to take the front housing off and try that.

I have the same machine, nothing but a chunk of hose that slips over a stand-off. I replace mine when I do belts with the front housing off. I believe 5/16 fuel hose works well.
See also impeller won’t stop spinning thread from a week or so back, use the search function when you are logged in and it will come up.
Actually, I see that was your post.

What the heck is that part for? Just to avoid metal to metal contact? To take a little sound away?

I believe it is a brake pad to stop the auger pulley from turning when disengaging.

100% right on, the idler that tensions the blower belt and the tube brake are on the same bell-crank at opposite ends. Pull down on the lever and the brake lifts off the blower pulley and the idler pushes the belt tight, let it go and the and its vise versa. Very basic but effective.
I have had this machine 20+ years and know it intimately.

Great feedback you gave to the OP. Don't have this machine but am always impressed when something is designed simply and can maintained without hassle many years forward. Good read!

thanks for the info. bnurczyk that's what I needed to know. Now to take the front housing off. It seems like a lot of work just to replace that little piece of hose.
