WATCH FOR broken snap ring groove/friction disc assembly

just a heads up, when buying old machines, take a look at the friction disc assembly, my Drift Breaker 10/32-14" came in with a friction disk assembly similar to this one, the snap ring groove and snap ring were broken off the casting from shifting it. so it needs the entire retainer casting with a good snap ring groove, just to put the snap ring and throwout bearing back on and hold it there. that snap ring takes all the pressure of the gearshift movement when shifting gears.

a clean break occurred around the snap ring groove, a ring of metal broke off and there is nothing there to hold the snap ring in place. this makes the gearshift mechanism inoperative.

Is that a Murray. I see that unit in parts tree, or other sites. hopefully you can find a match. Probably not enough "meat" on that sleeve, or too brittle material, but a lot of seasons of use.

Question

You say it was broken off from shifting it.
I guess then someone abused it and shifted the wrong way?

It is not normal for it to break just from shifting it if you shift the proper way right?

Edit,
OK maybe from a lot of use, huh?

the hexagonal hole in the center, has a tendency to get stuck on the cross shaft it rides on from sitting, lack of lube, and corrosion. most of these never get opened up unless something breaks.

the owner gets the machine out for winter, tries to move the shifter, it won't budge. about half the old machines I bought, had stuck shifters from sitting. I pull the cover, spray them with PB blaster, oil/grease the shaft and they come right free.

some guys muscle up and try to FORCE the shifter to move, and presto break this snap ring right off the retainer casting, then the throwout bearing and snap ring come off too

in this case the casting is aluminum and there was not a lot of material there, the machine is up at my Mom's but I'll get pics of what it looks like when it breaks off. the snap ring, bearing, and piece of broken casting all hang there from the cross shaft, all disconnected from the friction disk assembly.

it looks like they made them better in later years.

the Craftsman expert and mod here, is looking into a spare for me.
I can get a spare from the junk machine I left at another guy's place last weekend, but that is a 90 minute drive each way. trying to find one that can be shipped in or locally.

we'll get 'er ! compared to the Cub Cadet and Gilson, this is small potatoes....

Who would that be?
Shryp?

Most seem to just knock a Craftsman here, and not just the mods.

But at least a Craftsman is recommended over some of the other brands.
There are a few around me that have Craftsman's and they all work fine.
I guess the dependability of ANY blower is the person who operates it and how he/she takes care of it.

it was a Craftsman Drift Breaker 1978, the big mutha' in my other thread...3 stage with headlights. Made by AMF ? or Murray or Noma ? it may be an early Murray...

all of the above you said is true- not enough material there, brittle material aluminum casting, and an old machine with lots of miles on it. The condition of the impeller says it saw a lot of obstacles, every impeller blade is bent a little, or a lot- and one shear pin is snapped off in the hole of the auger shaft.

if your question is serious, not just kidding- this fella Paul, has done more with the old Craftsmans than anyone I've run across on the net. check out his photobucket and threads ?

old Craftsmans from the 1970's are made by AMF and can go head to head with any Ariens, Gilson, Snowbird, Jacobsen of that era....

the late model recently made Craftsmans are tinny made in China machines, hit a drift with them, and the chute spreads, and drops the auger shaft on the ground....that actually happened to previous owner of the 5HP track machine I had.

Old Craftsman machines were made by a few different companies. If the model number starts with "536" it could be AMF, Noma or Western Tool & Stamping that produced it. I think mine is Noma.

yes true but they were all the same basic design between those 3 makers, and it all stemmed from the original AMF machines- so many of the parts interchange between the 3 makes.

it was badge engineering i.e. Chevy, GMC trucks- same truck.

I just looked at a single headlight Drift Breaker like yours yesterday- but I passed on it. this one had friction drive 8HP 3 stage, 1978, HM80 engine

is yours a friction or gear drive ?

what's the model number ?
