Ohio_hunter,
Apparently you have a pump and motor that the stars were lined up just right. In other words, you got a good one.
Having been in RX (Reliability Excellence) the past 9.5 years repairing everything from a simple check valve to wire guided vehicles, proper and religious preventive maintenance was key. Many would be curious how you treat your YH.
Short cycle times to minimize excess heat can be a factor, some have said avoiding the max psi of the compressor, and god knows what else could contribute to premature failure.
To me, and others have said it, a YH is best suited for direct gun filling and not so much for Great Whites, which also means not topping off of Great Whites or similar volume CF’s. Maybe a thread should be started for YH or YH copies should be started with time to failure, temps, maintenance performed etc. to sort of document or predict trends.
I have an Alkin, not because I’m a super user, but might be in the future. I own an Alkin because I suffer from a gear hog disease. On the upside, if I burn out on airguns I can sell it for a decent amount.
