roof pump noise. after replacing hoses roof latch, I hear ringing in pump, oil loses some hydraulic cylinders, I found oil under the rear seat, the squeak is air in system ... effort ¿.
I low fluid in the reservoir after several operations, when comes the shriek principalmete ... besides getting a little slow operation.

 

sorry tanngo, can't understand your question buddy.

The pump will make a noise when operating. Its normal. Running the top through several cycles should move all of the air from the system. It may take more than a few if there is alot of air. If you lose oil again, you've got more leaks, and air will continue to get in.

 

gracias h20boy.
I have leakage of hydraulic cylinders, pump causing the noise, I wanted to know.

 

I have noticed over the past few months that the hood operation is getting louder. It is usually at the beginning of the cycle when the roof is being raised. It then happens again towards the end of the cycle when the roof is almost closed. It sounds like hydraulic action and it is very audible and getting worse.

 

Is the oil level in the reservoir going down ?
Have you got a leak in one of the lift cylinders?

 

I understand that you have a leak in at least one cylinder. That will have to be removed and rebuilt. The noise may be due to low fluid, is the fluid level between the lines near the middle of the reservoir?

 

gracias .

fluid level ok, cylinders leak. Argentina repair not available, I can use it to ?

 

I don't understand - if you've got a seal leaking the pump fluid level would go down.

 

While not directly addressing his full issue, one thing Tanngo mentions is the "ringing noise" when operating the pump. I too have this noise. I know it is air in the system. Whenever I close or open the roof, when the pump first starts, I hear air in the system for about the first second of operation. It clearly is air, yet seems to have zero affect on the operation of the roof. This has been happening for over a year ever since I replaced the latch hoses, yet, I can positively without question confirm that I have absoloutly no leaks anywhere. I marked where my fluid level was last year, I open and close the roof nearly every time I drive the car, and the fluid level has never dropped when I recheck the level. I also have pulled the rear seat recently for other reasons and inspected the rams, dry. The last time I pulled the latch cover to inspect things it was dry too. I presume that there still is air in the lines somewhere and for some reason never was purged. But it has not affected operation, so I just have left it.

 

Steve,
I have doubts about the 'self-purging' bit myself.
It is a closed system and while I can see the volume of fluid displaced by the lift rams would be enough eventually to purge air in their lines,
it seems surprising that, given small displacement of the latch cylinder together with the length of the lines (and hence large volume) would let this part of the system purge.
Gus, who knows a great deal about the hydraulics, says it does though.

 

sorry idioma

latches replace hoses 2 weeks ago, now ... leaks in the hydraulic cylinders, liquid added bit annoying squeak at first. ¿¿A danger

 

leaking cylinders means less pressure in the system, those leaks can worsen, and one day, you won't have 'automatic' operation of the system. Good time to manually bleed the air out as well?

 

Thanks everyone, sorry for language.

 

tanngo, language not a problem. Here is a rebuild service several members have used.
XK8 XKR Convertible main lift cylinder upgrade service - Top Hydraulics, Inc

 

RJ - his problem is the same as us Europeans - shipping from Argentina.
Top Hydraulics won't supply the seals separately.

 

accurate, I have to buy new cylinders. imported. I thought , seals lubricated hydraulic elevators ... put pure silicone handle cromo ..
gracias .
