The parts came when promised. I was hoping that the nut would also be included. I had to go to hardware stoe and buy the locking nut that goes with the bolt

Misleading shipping details.
The product finally arrived. I left an other review this product came in a flimsy shipping bag that took two weeks to get here. IT said three days guaranteed. They left some lame excuse that I paid for ground and they don't guarantee ground shipping. Good thing I took a screen shot of their lie. I'm done with this company.

If the augar turns but as soon as it hits snow it stops? Reasons? Ty
Jeff For model number 927 sbexp - October 16, 2022

Hello Jeff, Thank you for inquiry. Researching the model number that you have provided, first check for any blockages that could be causing the auger to stop. If there are no clogs, then check the shear pins to see if any of them are broken. Another cause is a dirty carburetor, so make sure the carburetor is clean and you have a good fuel flow. Good luck with your repair and if you need assistance with placing an order, please do not hesitate to call our customer service, open 7 days a week to help you. We look forward to hearing from you.

Just put the pins back in. The problem was in finding the pins. Went to 3 repair shops in my city. Went to four hardware stores, nobody carried the Husqvarna type of pin. That took 1/2 a day of looking. Finally went on line, found your website, simple to use, got the correct bolt, they came on time as promised. I will go to you guys f irst, next time. RA

My Craftsman snowblower was rusting

I removed the auger housing assembly from the motor/pulley assembly. Removed the auger assembly from the auger housing, disassembled the augers from the auger axle and gear assembly, the sheer bolts broke off in the disassembly, as they are designed to do. Drilled out the broken sheer bolts from the augers and auger drive shaft. I disasse mbled the snowdrift cutters and various support parts from the auger housing. I used naval jelly to treat the rusted parts, basically the outer housing of the snowblower motor assembly, the augers, the entire auger housing, the snowdrift cutters and sundry parts of the auger housing. I then used a grinder and a poly paint removal grinder wheel to clear loose paint and rust off the outer housing of the snowblower motor assembly, the augers, the entire auger housing, the snowdrift cutters and sundry parts of the auger housing. I cleaned everything with mineral spirits and soap and water. Repainted all the parts with Rustoleum yellow or black enamel, where appropriate. I cleaned the snow deflector angle cable with WD40 and greased it with automatic transmission fluid, which was light enough to lube the cable without freezing in winter. Reassembled it all with new skid plates, new sheer bolts, a new auger shaft bearing and new click pins and tested it to make sure it still ran and functioned properly.

It all took several weeks but considering the cost of a new snowblower of this quality, and the effort to hand shovel a 75 foot drive every dang day next winter, it was worth it.

Punched out the remaining piece of the pin and replaced with new.
However, the nut that was sent had bad threads and I used one that I had in my collection of nuts & bolts.

Went to hardware store to buy the nuts that go with the bolts (took an extra day for them to be open, last OEM bolts came with nuts so this was correctly advertised but less than helpful because you nearly always need both by definition of what a shear bolt does and how equipment is used). Once I had all of the parts I needed, repair too k less than 5 minutes.

Make sure you purchase the right pins,( Look at your manual for the parts numbers) some dealers will sell you incorrect pins)! Make sure you put the pin in correctly. One side the hole is larger. Attach lock nuts. Again people will sell you plain nuts and call them lock nuts.
I read my manual, got the parts numbers, then went to th e web site of the manufacture to purchase replacements.
Note\" These pins are expensive and not always returnable!
