Where can I purchase the two types of shear bolts for my Kubota BX 2750D Snow Blower Shear Bolts. They break easily and I need to keep a quantity in stock. The part numbers are 5/16"NC x 2 1/4" silver plated Grade 5 and 5/16" x 2 1/4" gold plated Grade 8. Include lock washers and nuts for both (same size).

I moved your thread to the Kubota Owning/Operating Forum.

Buy them at your Kubota dealer. You probably have the same blower that I do - B2782. One of the bolts has a snap ring around it which you would not find at the bolt store, even if you got the correct grade.

Anyway mine have always worked they way they should. I actually bought the dealer out when I bought them. - about a dozen for the impeller and a dozen for the auger.

Kubota dealer as they are grooved. You should not be breaking them all the time. Find and fix the problem.

Welcome to TBN! My BX2750D takes P/N 70060-02808 (gold grade 8) for the fan and P/N 70060-01338 (silver grade 5) for the auger. They should be torqued to 9 lbs-ft. according to the manual. This is my second season and so far I've gone through 6-8 fan bolts total and still haven't sheared an auger bolt.

I also wanted a quantity of them, but my dealer was getting almost $2/bolt. So I bought a bunch of bolts each grade from Napa & grooved them myself. I have a small metal lathe, but I'm sure it could also be done with a drill press & Dremel or hacksaw. Duplicated the groove positions & depth with a caliper. the auger pin has 2 grooves, the fan pin (grade 8) has just 1.

I paid $1.25 for them last year, bought some this year and they want $2.50 for them.

Why would they use a grade 8 bolt for a shear bolt? grade 8 is the strongest bolt there is.
