I have a 2005 Mack Granite roll-off truck that recently spun a rod bearing at 400,000 miles. It has a AMI 370, Serial # 5k0232. We tried to replace the rod bearings only and it lasted about 20 miles before it spun again (we think the same one #6).
Not sure we really want to attempt a full rebuild in our current shop (its not an engine shop... pretty dirty)
My question is, what is the best option, in your guys opinion to proceed. The truck is not in bad shape and I plan to keep it for a few more years at least.
Long block reman?
Used engine complete? Will any AMI engine work or does it need to be 370hp rated?
We are a small family owned business and I am trying to get some options before we proceed.
Thank you for any input
