Craftsman mandrel housing substitute
I have a Craftsman YS4500 that I believe is 6 years old.Model 917.276683.
The mandrel housing broke and I ordered part #187281 listed as an approved substitute. I also got a new pulley, locknut, spacer washer, spindle shaft and deck mandrel bearing. I did not get the mounting bolts. When I took the old mandrel out the 4 bolts that held it to the deck broke off. The whole thing seems to be cast.
The new part is not threaded(mounting holes). Does anyone know if the original bolts were self tapping. I do not feel safe trying to tap this pot metal and believe I will get some long bolts to mount it but I am curious if any die hard Craftsman mechanics might be able to shed light on this? Thanks, Sharon
