Restoration 536.884810 5hp/23" width Craftsman II Trac-Drive

Just completed my first snowblower restoration project!

Recently purchased a 536.884810 5hp/23" width Craftsman II Trac-Drive on Craigslist. It ran, but motor seemed weak and the Trac-Drive train was a bear to use. It seemed frozen and binding.
Today, following a piece-by-piece tear down, inspection, and restoration or replacement of every engine and drivetrain part, I am proud to say that the snowblower looks and runs like new.
I learned a lot working with this model. It proved to be more complex and in need of more obsolete parts than I ever would have imagined.
If I can help you with what I learned, let me know!

UPDATE: Kudos to stuart80112 for excellent discussions and documentation of working on his 536.884810 machine. Similar kudos go to PLZ523. To make searching easier, I have copied the following entry and links to TracDrive photos posted by stuart80112.

Welcome to the forum, you should have joined before you rebuilt it all. Then you could have done a rebuild thread.
Have you been so lucky as to have snow to try it on yet?

This last storm that predicted my area yesterday and today said we would have 12" plus....... turned out to be 1/16 of an inch for me.

This guy might need some of your expertise on the track drive.

Check out his thread and jump right in if you can help him out, https://www.snowblowerforum.com/forum...ck-drive.html?

I hate shoveling SNOW!

Welcome, to another tread-head. There is something to be said about complex machines, then tend to make you look for more complex machines. Mine, is my "Ricky."

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.

Welcome

Welcome to the forum. One suggestion is to watch those tracks. I've seen and heard they can rust onto the respective shafts and become hard or impossible to drive.
I've also read where some people drill into the hubs to add grease zerks to them and supposedly have had good luck with that.
Good to see another 'old girl' running like a 'young chick' - congrats.

Thanks Guys...

I agree that the Trac-Drive is the best and worst feature of this unit. The plastic hubs that secure the tracks to the 3/4" main drive axle are VERY prone to building up rust inside the hubs, as well as in the chain sprockets that drive the track wheels. That creates tremendous friction where you don't want it.

The rust in my hubs was so bad that the snowblower could not be budged forward or backward without power. That created excessive wear on the the friction disc and the hex shaft, so much so that the bronze hex shaft bearing was wallowed out and cracked, and the friction wheel rubber was toast.

The main drive shaft could not be removed from the unit without cutting it in half, since the chain sprockets in the trac-drive were "welded" to each end with rust. After cutting the axle shaft, I was finally able to salvage the sprockets following a day in 12-volt electrolysis with sodium carbonate. That is among the best rust removal techniques going. Brute force with a gear puller was only bending and ruining the sprockets!

I have not installed zerks on these track hubs yet, but I will very soon since pushing grease into them is a great way to keep water and rust out. I did already install a zerk on the friction drive plate input shaft to preserve the 2 new needle bearings. Also replaced the hex shaft bronze bushing with a ball-bearing equivalent from Ariens. A big shout out to "td5771" for "Fix to avoid big failure on Murray machines"; and to "archangel" and "Shryp" for the hex shaft bronze bushing replacement with a ball bearing. See "Craftsman 5-23 Track drive...PARTS N.L.I.S?"

Sure like the idea of stainless steel shafts to replace to steel versions so common to all these machines!! Would be very easy to make up on a lathe.- guess that will be my next shop investment. [IMG class=inlineimg]/forum/images/smilies/wink.gif[/IMG]

This is a sweet little forum - Thank you!! [IMG class=inlineimg]/forum/images/smilies/biggrin.gif[/IMG]
