Dirrect Replacement,

July 6, 2009

By 1HappyCustomer

from Southaven MS

"I replaced an 11+ year old 12hp Briggs & Stratton engine with this engine. It was a direct replacement. Mounting holes and electrical connections were the same. I was a little surprised that the mounting bolts had to cut their own threads into the new engine block. But I just take my time and pre-cut the threads before mounting. I am very satisfied with the results."

Was time for a change.,

March 7, 2007

By GRodman

from Yorktown, VA

"I replaced the engine in my 1989 38" riding mower, this mower was given to me 5 years ago with a worn out engine, I procrastinated for a long time about keeping mower until engine finally just plain blew up. I questioned the value of repairing mower until NorthernTool bailed me out again. On one hand I could have spent more and replaced whole mover, but for the Price and quality I am glad I replaced engine. The exchange was flawless, no drilling in deck frame, no modifications needed for drive pulley, wiring needed a little work but only because engine was 18 years newer and a different make, but in all the yard work was only delayed about 90 minutes from the time I blew it up to when I started it back up."
