I just successfully replaced a 8hp Tecumseh engine with a 10.5hp B&S engine on my Murray riding mower. Everything is working great. The machine is 16yrs old and the next major component that is still original equipment is the transaxle. Although there are no signs of any malfunctions, I'm concerned that next season or the one after that it might quit.
The transaxle is a 5 speed manufactured by Spicer/Dana p/n 4450-3, model# 056191. Spicer no longer manufacturers this part. Both Murray and Craftsman parts lists show no substitute part available.
I have searched the internet up and down and all I could find were used ones. Anyone out there know where I might find a new replacement or an adequate substitute? Any other suggestions would be appreciated.
