So, I'm just going to go wild and swap my pump elements myself. I have a total of 12 cam rollers of various sizes to adjust the port closure/start of delivery.

Should I:

1. Just swap the elements and leave the cam rollers the same.

Or

2. Swap the elements and choose a selection of cam rollers that is even as possible.

I realize this is just blindly swapping parts but I'm looking for a best course of action to reach a baseline.

Now, my second question:

If the pump has a balanced delivery but the port closure/start of delivery is wrong, will adjusting the port closure/timing effect the volume from that element?

How about the reverse. If the port closure/start of delivery is balanced but the volume is not, will balancing the volume effect the other adjustment?

Thanks!

If your port closeure is not exactly phased, your per-cylinder timing goes off the wall, which is a bad thing.

If your quantity is off, you get mismatched power, excess vibration, and etc. Also a bad thing.

Changing a plunger/barrel assembly nukes both of those adjustments.

Best bet is to get the Bosch MW 6 cylinder service manual that's floating around, read it, and get a feel for it all.
There's also some service training slideshows floating around on the governor, and what it all does. With luck, we'll have a less grey-area resource on the governor soon.

This is the electronic pump so no governor to worry about. I'm familiar with the individual effects of each of the 2 adjustments. My main questions besides 1 and 2 above are:

Does the port closure adjustment effect quantity and vice versa?

If so, how?

I'm not sure if they do, but you don't want to try running with bad phasing, at best performance would be crud, at worst, it could cause damage.

Port closure adjustment, this is rotating the element? If so that controls volume. Height controls timing. Atleast on the MW pump. I assume it is much the same on the M as the basic operating principal is the same.

The height/roller size controls timing. Rotation/position of the holders on the rack determines volume. I'm trying to figure out if one effects the other and to what extent.

I'm leaning towards leaving everything set as is and trying it out for size.

I'm also building a simple test rig for these two adjustments so eventually, I'll be able to adjust them myself.
