Need help with P250-W-D-M-H268 compressor

Currently working on an Ingersoll Rand P250 compressor driven by a Deutz 4 cylinder diesel. Need to pull the IP but need to make sure the motor is in time before doing so. The manual (TM 5-4310-452-14) shows a drawing of the four gears, however it does not show the timing marks and their relationship. I'm aware that we should be at TDC on the compression stroke, but want to be sure of the gear relationship. Can find no reference to which timing marks are used (there are several). Any help would be appreciated
