I am posting Caterpillar 3304-3306 Service Manual, this manual has a total of 316 pages, but this manual seems for natural gas engines - 7Y291-up and 37Y1-up - oh well, I encountered "file too large" when attempting to upload. If anyone wants it, just message me with your email address.
I am looking for the same service manual for 3304 Engine, serial: 12Z31015. This is on Caterpillar 963, serial 21Z0267x, please email to zhao.joe @ gmail .com thanks!
The CAT publication number is:
SENR2253-02 - Systems Operation Testing & Adjusting - 3304 Direct Injection Vehicular Engine with New Scroll Fuel System.
Please help. Thanks a lot!
