JD's Motor Swap and 101 question thread.

[JD Dave]

Thought I would start a thread about swapping the motor in my truck. I already have the motor out and I have the other motor I bought from a member here sitting as a long block that I'm getting ready to put back in.


I'm trying to put the CP3 pump in right now and and something isn't right as the gears don't line up. Can you put the CP3 gear on backwards? The modified pump came with the motor.

The CP3 pump shaft is tapered. So I doubt if you tried to install it backwards to would even be able to start the nut.


Are you sure your not just feeling the resistance of the o-ring sliding into the hole?

 

[JD Dave]

The motor was very straight forward coming out. I didn't have to raise the cab. I actually enjoyed doing it.

The gear looks ok Dave. The fit can be a little on the tight side. Try greasing the o-ring lightly and tap lightly with a dead blow hammer. -Curtis

Shouldn't the gears be tapered the same way on the motor and the pump?

I did oil it, I will try the hammer if you guys think it's suppose to be that way.

They are the same way.

 

[IOWA LLY]

Try pulling the o-ring off and see if it will slide in that way. It should go right in without it.
Then will know its just the o-ring.

 

[JD Dave]

They are the same way.

Awsome, I promise there will be more stupid questions to come.

What ever question you have, I will probably have the same question.

how long did it take you to remove the motor?

I did most of it my self except for pulling it and it took around 6 hours all together. An hour of that time was cleaning up all the coolant that missed the pail. It's actually alot easier pulling the motor then doing the header uppipes and turbo for the first time. Got the CP3 pump in. Very easy after I new everything was ok.

It looks like I have to take the ATI dampner off to put the water pump on. Any special things I have to do? Or look out for when taking it off and putting it back on? I have a 36 mm 12 point and I will use Mcrat's idea for holding the fly wheel. Looks like it's torqued to 268 lbs.

 

[JD Dave]

I have a friend coming over that has the ATI puller to take my Dampner off and I'll put the water pump on and he'll put it back on. I didn't want to mess with it when I know very little about it. I also put a couple tacks on the water pump with the mig. The tacks were a little big but they shouldn't bother anything from what I can tell.

Looks like things are coming together Dave :thumb:

Looks good :thumb: It really only took you 6 hours to pull it? That means it would only take me about 12 hours :rofl:

Very straight forward to take out. I took lots of pictures and put everything in ziplock bags with where they came from written on the bag. I also have a lift which made it easier.

The Socal flexplate is a work of art. I finally got my bigger injectors, 625's and new rocker studs. Thanks Guy. Does anyone know the torque of the smaller studs at the top of the head? Not sure if it's 150 lbs like the rest of them. Probably be another month before I see my twins.

The smaller ones don't take as much as the bigger studs. Don't know the torque spec though. Flywheel looks sweet:cool2:

What does the impeller look like ? They're plastic and I haven't seen one.

I only welded the gear end. So no idea what the impeller looks like. I'm putting Mcrat thermostats in so hope that helps. I know I should do something about the impeller end but I didn't read about that untill I had it back on.
