12mm cp3 swap

[N2BRK]

I've researched and put it all together in my mind so far. Any particular gotcha's from you experienced folks? I've never swapped a CP3 One youtube video recommended a punching bag and case of beer nearby, LOL.

I'll need to assemble a list of O-rings and other add on items, but I can search for those part numbers. I'll prolly change my thermostats while the cover is off too, since they are original at 110K.

Thanks in advance for any seasoned advice

The only thing that never crossed my mind was swapping the gear off the stocker. Not a big deal if you have a vice and few blocks of wood. Just be careful.

Oh shit! I didn't think of that at all. Thanks, that's the kind of info I need :thumb:

If you have time and a vehicle and don't have a vice could do like I did.. Went to a parts store (o Reilly in my case) and they pulled the gear for me..

it just looks like a gear pressed on a tapered stem. I don't think that'll give me much trouble. Maybe a shim on each side with a few taps and a burb or two from my airhammer on the hub, no?

Hold the gear in your hand, suspending the pump, tap the shaft/looseened nut and the gear will pop right off. Easiest part of the job:thumb:

I had to put mine in a vice, but I'm a little guy so maybe y'all Heman can hold it bare handed.

Shims would probably work to to hold the gear from turning. I just gave the pump shaft a good wack protecting it with a block of wood. No need for an air hammer.

Wow that's surprising to hear. Most the time I go in with a simple question and they give me a blank stare then ask if it's 4x4 is it a manual or auto lol etc etc.
