Finally got around to disassembling the spare pumps I have on hand, a smooth case 10 mm, ribbed case 10 mm, and Iveco 12 mm. I still haven't finished cleaning up the parts and then coating them with WD40 or oil or submerging them until I can send them out to have them properly assembled into a frankenpump. Short of doing that, I want to know what is worthwhile to keep to build a DD 12 mm in a 10 mm ribbed body, MK IV style mount, injection pump.
The good usable parts I have so far are the heavier springs from the 10 mm ribbed body, 3 plunger shims (haven't measured their thickness just yet), 2 good QA collars, 2 good QA's, the 12 mm pump head, the 12 mm plunger, At least 1 solid N108, at least 1 good timing assembly, 2 sets of rollers & pins & washers & cages for the cam plates, a DE053 cam plate, and a DE643 cam plate.
From what I've read, I want the heavier springs to counter the 12 mm plunger's mass. DE110 cam plate is a solid choice to keep destructive physics in check thus minimizing cavitation. The DE053 cam plate seems to have a slightly steeper incline in comparison to the DE110. I have not looked at the DE643's profile yet, but the plate is in good shape. I wouldn't mind advise on how to make and indexable rig to map the profiles since these are not longer documented.
I'd like to extend the pump timing like some have done in order to have proper dynamic range and eliminate white smoke on startup. However, I can't seem to find the specifics from way back when. I do recall a diagram being posted with possible dimensions.
This will be a daily driver pump with the occasional spritz up to 5000 RPM.
