O/T. For the Mack lovers
The big dog is in sad shape. Yes, she had developed a bit of a knock under load, so we took her in to the shop to have the big 998 checked out. Turns out she had a bad rod and a worn camshaft (the engine is virgin with 485,000 gravel and grain hauling miles on it). So the new parts are installed, that fancy fuel pump is re-bolted in in the valley of the big v-8, and the mechanics take it for a test drive. Well, the fuelpump is gear driven, and the timing is set by indexing the gear forward or backwards to get everything right...and then you tighten up the 3 bolts that hold that gear on. They forgot to tighten up the 3 bolts. It started great, ran great, and they got about 1.5 miles away from the shop when the gear skipped around, apparently injecting fuel at the wrong time when the motor was huffing right along...to make a long story short, she needs all new pistons, 3 new cylinder sleeves, another new camshaft, a bunch of valves and rods...the list goes on and on. Our Big Dog is layed up for a little while.
