Truecountry Posted August 31, 2021 Share Posted August 31, 2021 ok Guys bear with me ..i havent work at this shop but 2 years and this truck has engine sitting in floor for 6 years ...first engine had clutch replaced and old mech put in pilot bearing with snap ring on it ...ok i get why it broke that crank shaft ...now 2nd engine no snap ring on pilot bearing and it broke crank in 15000 miles this was a mack reman ..and boss didnt have a mech at the time to pull it before warranty ran out ....my question is can i have transmission problems now to break this crank ..im the clean up mech ..i get the shit everyone else has played with but not fixed at least its not torn apart and in buckets lol Quote Link to comment Share on other sites More sharing options...
fjh Posted September 1, 2021 Share Posted September 1, 2021 (edited) So here's something to think about ! WAS THE CLUTCH ADJUSTED properly on this second failure ? Lack of free pedal can take out the thrust bearing and cause a whole dogs breakfast of issues ! including what you have. I've Seen it happen! Just sayin!

mrgumby Posted September 2, 2021 Share Posted September 2, 2021 Also did both engines use the same harmonic balancer or did the new engine come with it own. I’ve seen some where you reuse your old balancer 1 Quote Link to comment Share on other sites More sharing options...

I’ve seen some where you reuse your old balancer nobody knows if they reused harmonic balancer but today i pulled trans and drained it oh my god at the metal ..pull shifter cover and input shaft its a snap ring with washers the housing is broken and snap ring was just spinning on shaft so i think bearing is also gone ...now im looking for a trans and engine lol my luck Quote Link to comment Share on other sites More sharing options...
