Question PS MK20 - what was the recall in the early 00's? Late 90's?

[OMyMyOHellYes]

The recall that had to do with overtightening the yoke nut and splitting the reg body - what specifically was the fix in the recall service bulletin? Replace saddle? Replace nut? Ream out reg body a little deeper?

I'm assuming, when I do the MK25 conversion, that if I do a DIN conversion that will supercede having the recall done? Or should I get the recall done anyway and then do the upgrade/service?

Scubapro® Recalls MK 20 Scuba Regulators for Service


Remedy: Scubapro® USA has been providing a service upgrade kit via the authorized dealer network since May 2005 which contains a Yoke or Din retainer that prohibits over-tightening during annual service. Consumers can easily identify if the service upgrade has been completed by counting the vents on the plastic saddle located on the regulator.

It's not a nut, it's like a 'bolt' called the yoke (or DIN) retainer. If you have a MK20 and you are getting a DIN kit to change it from yoke to DIN, that kit will have the new style retainer. It's been a few years since I've even seen one of the older style DIN or yoke retainers on a MK20. That recall has been going on for a long time.
