CFR MPS rebuild, Copy of instructions Options

[Ron914]

I needed to rebuild my MPS but Chris Foley is out of the kits due to no longer having a supplier of the BE-CU diaphragms . I was lucky enough to have a member here offer to sell me his spare parts kit from Chris (Thanks Tom). His kit did not have the instructions with it so I am wondering if anyone has a copy of those instructions?

I agree. I think anders is really doing the deep dive, which is great, but you don't need to overthink it. It is three adjustments and you can watch the outcome yourself.

The initial setup is easy, just do as Chris says, then check the curve to make sure it has the right shape, pop it in the car and tweak the inner and full stop till it is doing what you need.


And you don't want it leaking. Not only does that make initial setup and idle difficult, but a small leak probably means a cracked diaphragm and that will break as you start to actually drive it and stress it. When I bought mine it went from running good enough to broken diaphragm pretty quick as I was daily driving it.

And ignore the inductance numbers themselves. You just want to make sure the curve looks right you just want to plot the inductance at each inhg increase or decrease in vacuum.
