Boone, Iowa | I just did this on a 9370 that I had to replace the cam. Firing order is 1-5-3-6-2-4. There are A-B-C marks on the accessory drive pulley and a pointer on the front cover, below the A/C compressor. With #1 on compression, both intake and exhaust rocker arms will be loose. I like to torque the injector down 1st to proper torque. You will find that reading on your tin plate on the front cover. This one was 125 in/lbs. The intake will get set at .014" and exhaust is at .027". You will do #1 on A, #2 on B, #3 on C, #4 on A, #5 on B and #6 cylinder on C. You can take an 1 & 5/16" socket and a long 1/2" ratchet on the accessory drive pulley nut and turn the engine clockwise, looking at the front of the engine. If you have had your injectors out, make sure the o-rings and rubber sleeves on the steel oil line below the injectors are good. I replaced them on the #1, #3 and #5 injectors that I had out to set the timing of the new camshaft. When you start up the engine with new injectors, it may smoke and rattle for a while, but the injectors take a little time to get filled back up with oil. |
