So are those rods in Bruce’s restoration from the factory and only in certain 515 models? Because as Jerry mentioned, the skins are what hold the pump up.
Another question arose while I was tinkering with this pump. Bolting the skins to the upper and lower base is no problem, but how do you bolt the skins together along the two vertical seams? Once the skins are on, you cant reach 5’ up from the bottom and hold a nut??? Most pumps I have dealt with have the little tabs on the outside that you just bolt together. This pump has holes drilled through one skin and into the other skins recessed holes. (This one is tough to explain, unless you know what I’m talking about).
And here’s the two pipes in Jacks literature that I asked about earlier (red arrows). Do they provide any structural stabilization. I heard they do not. The pipe on the left sure looks like the one in Bruce’s restoration. I can definitely tell you that there are NOT three mounting holes cast into the base like a 615, there is only one (and none broke off). Thoughts???
Thanks for reading / helping,
Steve
