Hyster-Yale PSI engines - How they holding up?

How's everybody doing with the new engine (introduced on 2015 models)?

I took delivery of my first units with this replacement for the Mazda second half of last year. I've got seven of them in service now.

Initially, they've performed without any significant issues. Just some grumbling on the maintenance end that they are more difficult to work on due to the cluttered engine compartment.

Just this past week though we may have discovered a **** in the armor. One unit had a head gasket fail at 2300 hrs. While it is possible that the truck was overheated, it's not certain. My dealer claims this is the first such failure they've seen.

For comparison, we collectively put over 2 million hours on our fleet of 2.0L/2.2L Mazda engines and maybe had one head gasket failure. And that occurred at ~25K hours.

I'm certainly hoping this proves to be an anomaly. I'd like to hear how others are doing.

I think you meant to say the motor IS interference-type: Belt breaks, valves and pistons go "bang". Buy a new head.

The Mazda, on the other hand, is non-interference: Drive it 'til it breaks, coast to a stop, replace belt, re-time motor, get back on the road.

We'll be coming up on belt change intervals probably in about 6 months (we do 4k-5k hrs/yr). It'll be interesting to see the cost.

What was the nature of the warranty issue? Anything significant?

I had warranty issues on one unit and it was a PSI issue was it was resolved in all due time. I have had no issues with the other 9 units I have here other than operator issues (also known as abuse). I have all but 2 on power mode 2. They pull ramps and seem to be very well thought out. My only concern is the motor is a non-interference type and Yale says to replace the timing and counter balance shaft belts at 5,000 hours. Will miss the Mazda powerplants. Time will tell on these units
