    Hi guys. Recently pulled my NP241 to give it an inspection/reseal and I found out that my rear extension housing was cracked in two places. Both cracks were half way from the bolt hole and the housing so I basicly had only 2 bolt holding it on all along since the others were detached. What causes this?? I will need a new one and I hope they are not expensive. Thanks for the help.

    Two things over tighting the bolts or at some time in its life it was dropped on the tail housing. The tail housing will work off of left hand drop np 241. The piece that is broken is the one with the main bushing for tail shaft and the output shaft seal. If needed I have one that is off a np 241.

    There is no "parts wanted" or parts "for sale" in the Garage. Use the classifieds here...

    If my extension housing was cracked I'd just suck it up and go SYE right away. A bit spendy compared to another extension housing, but it isn't ever going to crack.
