Have tried to contact "Sea Space' . No reply. Anyone able to contact?
Ok, I'd like to fully, ( and respectfully) comment on the Sea Space pump mount.
Honestly, it's a bad way to do it, and they haven't addressed some very important issues.
If you review my original post, which was obsessively thorough, I showed how to mount the pump without pulling ALL the crankshaft pulley bolts at once. This is what I would loosely refer to as "a bad idea"
The very cool method of installing the studs does 2 things:
You can install the pump and ensure the crankshaft pulley and harmonic balancer don't shift.
And, if you want to pul, the pump for service. Etc., you just unscrew the nuts and it pops off.
BUT, what I really don't like about the Sea Space. Is that they didn't cover (at all) one of the most difficult aspects of the pump installation, and that was how to keep the pump body from rotating, while the base is spinning.
And here is where I remind you that I hadn't totally figured that out when I posted the article. You see, this is very challenging.
The pump is moving around in all directions with the engine as its jumping for joy on its mounts. The theoretical way to stabilize the pump body (which has a 5/16" threaded post), is to somehow attach a linkage arm from this to the engine surface
3 words... Good luck Chuck
The pump is way too far from the engine to fabricate anything resembling a stiff brace, and I spent more hours staring at my engine imagining how to do this, than watching the entire Breaking Bad series 3 times.
And I bent up a lot of aluminum in the process.
So, I cheated.
As you will note in my article, I mounted an aluminum angle across the engine bed, put a shoulder screw stud in the pump, and made an angle bracket with an oversized hoke that tge shoulder screw could "float" in. Yes, it wasn't a great solution, and I said so at the time. But, I didn't see anyone responding to my post (although hugely congratulatory ), saying "Hey Art, you should try this"
So my shoulder screw has been rattling around in the oversized hole, making it much more oversized, and finally reminding me quite audibly that it's time to get this finished.
So I went (solo) for an all you can eat sushi dinner, taking my McMaster Carr catalog, and a stack of paper. Now, I know what all of you are going to say...
"How did you get McMaster Carr to send you a catalog"
After an hour and 58 minutes, ( maximum seating time is 2 hours), I sorta had it.
Now, I'm really sorry I don't have any pictures to post. I blame Apple
The concept is simple. I used a compression spring interface between the pump stud and the engine bed mount. A compression spring will float in every direction, and will compress over an arc, which is exactly what you need this to do. Little tricky, but you need to cobble together some angle brackets which you can mount the ends of the springs to. One angle bracket mounts to the pump, and the other to the engine bed .
But there is one other really important thing that (a rightly selected) compression spring will do: it acts as a limited extension spring.
And here is why this is very important.
On the F5B-9 pump, (actually all pumps share this phenomena), when you shut the engine off, there is actually higher pressure on the outlet side than the input side. What this wants to do is run the pump backwards. As the F5B-9 is a 2-part pump, (versus your standard integrated pump), the rotating pump tries to rotate backwards until the pressure equalizes.
On my original version (with oversized hole) the sound and force was noticeable. So. I pre-biased the pump in the running direction by securing the outlet stem with shock cord. Very ugly,
So, by using the compression spring, it now compensates for this by floating counter clockwise very briefly when the engine shuts down. And with no banging, etc.
So, here is what I'm saying .
I you want to install tge F5B-9 pump to end your impeller changing misery, I highly encourage this. I would not ever count on changing the 4JH impeller anywhere except at a dock the way is is originally configured.
But, be aware that the spacer kit being offered is a very small piece of the puzzle, which now has a full solution.
And when I get an Android phone, you can see what it looks like.
