Scubapro 1st Stage Servicing Questions

[halocline]

Considering that you put a yoke reg on a DIN valve and took it for a dive, you should probably get that regulator completely rebuilt.

Not that it matters, but you don't need to 'give up balanced' with a 109. You just convert them. The performance is about the same, balanced or unbalanced.

Ah, I didn't know you could convert the 109s to balanced. I'll look into that route, should I decide to go with a left-hand reg.

Anyone know where to buy equivalent (or OEM) hard bits for the SP MK10? I'd love to find a source of shims (piston, turret), a HP spring, and the cone filters.

It isn't critical since these parts rarely wear out, and I can clean the filters. I just like to have a spare on hand if it is needed.

HP seats are easy, they are a standard Trident item.

Hi @raftingtigger ,

You can stamp out shims from a plastic milk jug if necessary.

All SP first stages except the MK5 and new MK19 use the same swivel retainer: 10500104 and washer: 01060500 (the new ones are not as wide as the older flat ones but work just the same)

Filters and loads of other stuff are available at Scuba Gaskets
