 Kubota BX2750 Snowblower Fan Shear Pin Alignment

I have had this blower since new for 10 years and periodically have changed the shear pins when they snap.

This year the blower fan shear pin broke as it has on other occasions. In the past it was a simple 20 second fix.

This time it took an hour to hammer out the old pin. And it seems that the hole in the fan and the fan shaft are slightly off. So much so that to get the new shear pin I had to use a ratchet wrench to try to work it into alignment.

Well I was able to get the new pin in until it hits the obstruction of the out of alignment fan hole. Lots of tension on the pin. I will have to use the ratchet wrench to work the unsuccessful pin install out.

Puzzled as to what is causing this out of alignment issue now. I could spin the fan by hand when the pin was out and it seemed normal. When I put a punch down the hole it seems to be 1/16th off, where the fan should be closer to the auger blades.

Any ideas? Need to disassemble?

Murf,

One of the problems now that the alignment is off, due to what you mentioned, is that since the blower fan is not HUGE, there is very little swing room, more a light tap of little consequence.

My regular punches were all too long to even tap the shear pin hole in the tight quarters. So your home made drift punch is on my to do list.

I wound up trying to realign the fan by gently using a pry bar and using a punch and hammer to tap the fan near the fan shaft. I still had to tap the shear pin through though so I know from now on it will be and issue.

I wish there was some sort of C clamp tool to use in tight quarters like the brake part tool pictured here for tight quarters

Murf I am sure you were the one who gave me this tip. Worked like a charm in the tight space on my blower fan. Done in a minute !

Thanks!

May be too soon to think of snow.. Update to this two year old post from 2107. The home made bolts Murf suggested worked great in 2017 and 2018. The bad alignment worked itself out on the blower fan and was not a problem in 2018.
