Pump Alignment/Install

[paczowski123]

So I started messing around with my Chan and trying to get the pump aligned, but it's not going as planned. It seems every time
I get the driveshaft coming through the hole in the center from left to right (before I even mess with the up and down height) the pump mounting holes are off. I have read a few how to's but when I try to follow the steps the holes don't line up. Even when I try and just put the front two in they barely even line up perfectly. Any tips? I put an example of what I have below:

Take a burr bit and make holes in reduction nozzle and wear ring bigger if you have to pretty common

I thought I had read somewhere of someone having to do that, but wasn't sure. I suppose once locked town and torqued the pump won't move out of position?

This is where the cold fusion tool can save you a lot of time aligning the driveshaft/midshaft.

 

[paczowski123]

There's a tool??

 

[Ducky]

Yea man. I don't have a link because I'm on my phone. But it's in cold fusions site. I have one...id be willing to mail it to you if you could get it back within a week or so.

 

[paczowski123]

Yeah I found it, still looks like it requires you do do all the shinning and stuff beforehand and use the tool to test...man, I was hoping there was some sort of tool that would hold the pump/shaft square so all you had to do is figure out where to put shims and where you needed to clearance holes etc.

Also, no need to mail it to me, no telling when this thing will be done. Every time I touch it I get so frustrated I want to kick it off the stands lol

Tool is bad ass man you shim the plate if you have to then all you got to do is put midshaft housing on and put shim where it's needed

 

[paczowski123]

One thing I never understood about shimming the mid shaft was how the deal would be affected? If you shim it, doesn't it reduce the amount of pressure on the midshaft seal?

 

[Ducky]

It helps you figure out the actual center between your Midshaft bolts. It's possible that your driveshaft tube is not perfectly centered.

 

[paczowski123]

Well yeah, but in order for the midshaft housing to make a good seal, doesn't it need to be flush against the firewall?

 

[Little_Franny]

A little shimming can be fixed with silicone. In a perfect world the bulkhead would be true 90 degrees to driveshaft, but rarely is that the case in AM hulls

 

[paczowski123]

Ahh I see! Well looks like I'll be off to the hardware store next for a grinding bit to clearance these holes a bit

Likely your shoe is not in square. How does your intake grate look? Mine was out of wack. I egged my holes on my pump out first. Later on my shoe installed by steve came loose so I was able to reinstall it in correctly. If yours has the epoxy he used you can probably just tap it out.

 

[IS0LD0UT]

Oh and my shaft was not centered in the hole when all was said and done. It was however centered in the midshaft.

 

[paczowski123]

It could be, I don't have an intake grate, probably not going to run one. The intake tunnel is +2 so I don't have anything I could even mock up. As of now the shoe is just held in by epoxy it looks like, there are no screws. There's also no way I'm going to start fooling with the shoe, I'll notch the holes lol

 

[txsuperjetfreak96]

Pump shoe wasn't square on my aquabot so I had to pull it off actually got it off without destroying it lol

I egged out my wear ring on my kdx with a 155

Should I put screws into the pump shoe? And is there anything like 1211 I should seal up any open edges around the shoe?

 

[txsuperjetfreak96]

Yes use 4 screws at each corner use 5200 or equivalant
