Jewell County KS | I agree with bushton on them. I think they got the bad rap from the ones in trucks. I think it was from all of the overnight idling. I belive they had alot more luck in an ag tractor with the more constant rpm's . Dad and I have had 2 naturally aspirated 903's (265 hp) 1 since '79 and the other I picked up in 88-89. both have been good engines. As mentioned overheads every 1000 hrs and keep the coolant treated.
As for lugging they do drop rpm a little quick but you can also let the clutch out under load at idle and it will pull unlike the turbo 6 cyl. that has to build a little rpm's and boost first.
These are a couple of the dreaded MF that you like so well!!!! | |
