360 convertible top in SLOOOOOOOW Motion

The system is pretty simple so it can only be a couple of things. I would guess by your description that there's an internal leak. It could be the pump itself and replacing the motor was just an exercise in wallet calisthenics.

 

Was the system been bled properly after the pump change?

 

As far as I know, the hydraulics on the capote are self-bleeding. From what I've seen, somehow, the fluid can circulate back to the reservoir. It could be a pinhole at the end of stroke, or a valve? I have no empirical evidence to support it other than replacing rams and just running the top up and down once to get everything working right.

 

Thanks, John. Perhaps I was thinking of the F355

 

If the motor was just replaced I wonder if there are air bubbles in the lines.
When I flushed my fluids 2 years ago mine operated very slowly for about 3 cycles and then went normal

 

Either air in the line, cycle the top more or the fluid has become thick or is the incorrect fluid used. The hydraulic fluid is a very light and will evaporate over time becoming more and more thick causing slow operation even when it is topped up over the years. This is especially true in the 355 where the old fluid is trapped at the end of the system. Last thought is the vent screw is open for the emergency closing option?

 

You have a leak. Losing hydraulic pressure. Main ram or extention ram is the most likely culprit. Just do them all. Once one goes..they all go. 7 rams total.

Call Top Hydraulics..they will set you up.

 

The system will self bleed. Just activate to roof a few times. But be very sympathetic to pump run time..no longer then 20 seconds with a 20 second cool down between activations. With new fluid and no leaks..she will go.

 

F1 pump running with those timings is very bad .. refrain from using car until you duag and fix issue

I can assist if you want
