I have a new Honda HS928TCD blower.  Apparently a change was made in the past for the shear pins for the HS928 so now there are two types available, depending on the frame serial number. The older style pins have a P/N of  95701-06016-00 and the newer style is 92101-06016-0A. Since I have a bunch of the older style shear pins, I am wondering what the nature of the change was and if the older type of shear pins will work for the newer model.  If the old style is used on the new frame type, is there a danger to the gearcase because the shearing point is different?  See  http://www.boats.net/parts/search/Honda/Snow%20Blower/0/HS928%20WAS%20SNOW%20BLOWER%2C%20JPN%2C%20VIN%23%20SZAS-1100001%20TO%20SZAS-1129999/AUGER/parts.html for the illustrations.  Any ideas out there?

I would not risk using an ordinary hardware bolt for this application - even a grade 2.  Shear pins are designed to sacrificially break when your auger locks up on something hard.  Rather than the aluminum gearbox breaking.  Cost out replacing a gearbox and you will see why.

Woof,

the shear pins you are recommending via eBay are after-market bolts/nuts as they are not the OEM replacement.  my dealer stands by the Grade 5 so I am totally okay with it.   Again if you feel better buying the original Honda then go for it.

I know that people have used grade 5 without any issues but it worries me.  I'd use grade 2 in a pinch but my preference would be for the shear pins specified for the machine.  Most shear pins are either grooved or pre-stressed to insure that they will fail when the proper amount of force is applied.  Also true shear pins may be easier to remove compared to regular bolts. 

Just my two cents.

The after market shear pins designed for the Honda only cost 66 cents for the pin and the nut.  Why take a chance?

The Canadian Ebay seller responded to my question regarding the "grade" or hardness of these replacement pins;

 " Hello these will fit the Hs 624. The grade is the exact replacement grade as specified by honda for this application. They would be commonly known as grade 8.8 metric."

Can anyone tell what a "metric grade" might be?

 

Underdog,

Yes.  My bolts are in metric and say they are 8.8.  The 8.8 is written on the head bolt.

I did order some of these - still in the mail - should be here in a few days.  I'll let post here what they look like when I get them.

The spare spare shear pins that came with my new Honda 928 are hex head flange bolts.  On the cap, there is an "8" in a circle with an underline.  The nuts are self locking type.  I'll see how they compare to the new ones.

 

Left bolt is from my Honda dealer ($0.36) and Right bolt came with the blower.

The one on the right is the type that came with my blower too.  But I haven't taught them to play the piano yet.
