HPOP disassembly question
Anyone ever completely disassembled an HPOP before? Have any pictures? I'm fiddling with a spare pump I picked up for cheap and was wanting to tear it down to see the guts.

Thanks

The HPOP is a seven piston axial pump. Axial Pump Info Link

I've never taken one apart but here is a pic of "the guts". One thing I do know is that to take it apart the first thing you need to do is remove the rear plate. Take pics.

That rear plate does seem like loads of fun to figure out. With it being recessed, Mongo (me) will have to figger something out.

You can use a large C-clamp, front to rear, to slightly depress the rear plate to relieve the tension on the snap ring.
Of course this will also add in getting the snap ring back in.

I'm just curious what pump is in the pic? It's black like another pump I'm familiar with.

That pic was from a Ken Lux site years ago and is a stock pump. It only looks black in this pic, but wasn't. It was long before the SRP1 if that is what you were thinking.
