Recently had both front hydraulic rams rebuilt. Did my best to keep any air out of the hydraulic system. Apparently I didn’t keep all the air out. Front slide stalls/hesitates when retracting or extending (sometimes). I don’t halve any drawings for the hydraulic system. Does anyone have knowledge/suggestion’s for bleeding the hydraulics on a HWH system?

I do not on a Prevost. I helped my dad on a fiberglass coach and his system was self bleeding. If the slides are Prevost, have you called them?

Called HWH, they told me air will not completely come out of the system if the rams are connected to the slide. They instructed me to unbolt both ends of the ram from the coach/slide (not the hydraulics), then unplug the electrical connection for the lock & unlock pin solenoids to prevent any movement from the pins. Next run the rams in and out numerous times while they are not connected until they completely sink. Reconnect everything when finished and the air should be out of the system.
So far, so good

P.S. HWH said this is how they bleed the system after servicing.
