Message: [QUOTE="Hotrodtractor, post: 575435, member: 25"] I didn't say that you were using the HPOP gear either.... I said that the gear simply needed to be larger - enough larger that the center of the gear where the pump needs to be is no longer in the hole you want to use in the cover. If you just want to run a driveshaft out of the hole - that is very similar to the prospect of setting it up like I proposed earlier in the thread and provided evidence of it being done on a Dmax. Off the top of my head the HPOP gear spins at 80% crank speed and you need the pump to turn at 50% crank speed then you just need a gear set to turn 5/8ths the speed of the HPOP gear to get to 50% of the crank speed. So - you need a gear that is a certain multiple of 5 on the pump and the same multiple time 8 on the HPOP gear shaft. (10:16, 15:24, 20:32, 25:40, 30:48, 35:56, etc....) Of course this only works if the pump really is spinning at 80% crank speed - its been a while, and I would double check that if I was serious. [/QUOTE]
