Sooo, . . . . . Has anybody tried replacing the . . .

[cmann250]

I'd love to know where to find one under 150$,I can't even buy a trashed one

It'll all come back around when people stop trying to fund their P pump conversion from the sale of their VE pump parts. That trend is rediculous.

Hold on. Need to change the design.

Looking at my springs and stuff I found the Hydraulic KSB housing has a recessed pocket that the spring nests in.






It appears that those VE IPs not running a hydraulic KSB have a cover-plate that is similar to that of the hydraulic KSB control housing. Just no ports or Control housing.




Perhaps the adjustable affair could be of thicker plate, and drilled for the pocket?





It appears the Mechanical KSB uses the blank plate, with a shorter/stiffer spring. I suspect timing-device piston has a shorter stroke.




The Hydraulic KSB Spring is:
- Made of 0.115" diameter wire.
- .69" in diameter.
- 1.39" long.

The Mechanical KSB Spring is:
- Made of 0.125" diameter wire.
- .63" in diameter.
- 1.19" long.


There's most likely a number of additional springs to be had pending the application.

In our application, I think we'd do best with mimicking the OEM spring pocket. With that, one could run the stock/OEM spring and adjust as needed. Further, that OEM pocket is tapered to a smaller diameter at its deepest point. I believe that's to center the spring in the assembly.

- If you're NOT going to include provisions for a longer piston stroke (the spacer), you could perhaps simply fabricate a thick plate that's plunge-milled (?) the depth of the OEM spring pocket, the diameter of the spring. From there, alter the design to accommodate the adjustable element.
- If you're gonna include provisions for a longer piston stroke, you might increase the thickness of the plate the appropriate amount, and step-mill (?) it for the larger diameter actual piston bore in addition to the spring pocket diameter.

Ya' know what I mean?

???????????? OK. I assumed we could match how the inside of the ksb plate is..... but just making it spaced off at the same time.

That would be perfect.

My abruptness here was that I was thinking the new cover-plate (with the adjustment) was gonna be flat, with no pocket for the spring. Fiddling with the parts outside, I discovered it's not that simple.

Carry on.

What I was thinking of sending Joe (theredbeast) was a non ksb style cover plate, and seeing is how he has a timing spacer... he then knows what to make at what dimensions. I was thinking, just for sake of doing it, making the it a little more of a spacer than the typical spacer provides. Then having him make it adjustable from a "factory stand point" at all the way in, and a little more than a typical spacer stand point at all the way out. Of course the threads and housing would need to be hardened as to withstand the increased case pressure pushing back on the threads all the time.

I'll fiddle around on my spring manuf. site and see what I can come up with in a "factory" application that they carry for how stiff of a spring we could get that matches the factory one. ( I think we would want it to be the same, just maybe a little stronger ). If I can't find a stiffer spring in a factory application (meaning they already make it for someone else), it wouldn't be worth making one. In order for them to make a new spring design it is usually a $1,000 minimum order...... which sucks.

[RCCUMMINS89]

Well.... with a 10 second search with the manufacturer... I took a the measurements of the mechanical ksb, but with the length of the hydraulic ksb spring length..

I came up with 3 springs ranging from 275#/in to 380#/in load rate.... we should definitely be in business with trying different springs.

[revemup15]

I've found that moving the plug a little, has a
fairly large impact on the case pressure meaning:
a VERY small movement of the plug (don't go out
there and ping it with a punch and hammer)


Ummm are we onto something here?

[RCCUMMINS89]

Hugely onto something.... especially when accompanied by a stronger timing spring.


Does anyone have available to them a solid load poundage on the factory timing spring?

[Theredbeast]

here is my design so far

[BC847]

On to something for us 1st Gen folks, perhaps.

I picked it up from The VE fueled VW crowd a year or so ago. Not sure how long they've been doing it (though not many were at the time I stumbled upon it IIRC). I didn't act on it till I had some spare IPs and seal kits.

[Remps]

Iirc RSWORDS did that case pressure adjustment to his pump a couple years ago, and i think he had some trouble with spoolup after that. So a stiffer spring would definitely be needed. If you can make it work with a higher case pressure range along with a wider dynamic timing range id bet 2.5 hp per cc might be possible!

[RCCUMMINS89]

Joe, your picture is not showing up for me...... is it just my comp. or?

[RCCUMMINS89]

Joe, it's like we have the same mind sometimes......


So, I went and picked up a stock 205 timing spring today and a couple shims (free, courtesy of advanced diesel). Talked with the guy that knows the difference between his butt and a hole in the ground (such a relief) for a long time and got some useful information from him.

So I got home and knowing me.... I messed with my press. regulator. and quickly realized I needed to shim my spring a tad. So I forgot how pooping hard it is to take off all of this stuff while it's hanging off the motor. This adjustable timing spacer is going to be such an important tool to me I can't even begin to emphasize it.

If it wasn't for the fact that the good Lord likes to help me out when I'm in need , there would still be my spcer, one of the green o rings, 2 shims, and my spring lost in 2 feet of snow underneath my truck. . I took it all off and didn't drop a thing, and low and behold my ego/confidence shows through and I go flopping it back on there like I can't make mistakes and fumble the whole 9 yards.

I haven't driven it yet, cuz then the wife's car got stuck in the driveway..... I hate winter.

Doesn't take much of a tweak on the Reg, huh?

If I had a jacked up ramcharger with 400+ at the wheels, I'd love winter!
