RV Slide Out Operation and Troubleshooting
Hydraulic RV slide out mechanisms use a motor-driven hydraulic pump to actuate a hydraulic ram. Mechanical slides can fail due to low hydraulic fluid levels, fluid leaks, and defective valves.
Check for binding around the wall and ceiling if the slide out moves slowly or jerks when moving; if there is no obvious reason for the binding, it’s probably time to contact an RV repair center. There are two basic types of slide out mechanisms: hydraulic and mechanical. Hydraulic mechanisms use a motor-driven hydralic cylinder to move the slide out.
How do you fill a hydraulic reservoir?
Open the hood and look for the hydraulic reservoir, which will have a vented fill cap and a sight glass or fill gauge on the side to indicate the fluid level. Provide the fluid u2013 Remove the vented fill cap and insert the oil into the fill tube, then start pumping the liquid into the reservoir.
How full should a hydraulic reservoir be?
The volume of a hydraulic reservoir should be three times the rated output of the system’s fixed-displacement pump or the mean flow rate of its variable-displacement pump, according to a rule of thumb. For example, a system with a 5-gpm pump should have a 15-gal reservoir.
Does a hydraulic tank need a vent?
Because the oil level in the tank must be free to go up and down as oil comes back from and goes out to the hydraulic cylinders when you operate the tow truck bed, the hydraulic system requires a vent. When someone defeats the vent, it is usually unintentionally.
When should you fill hydraulic fluid?
When the machine is cold, do not fill it to the full mark; this will cause the machine to overfill when it warms up. Instead, wait until it warms up and then add enough fluid to bring the level to the full mark.
What is the proper way to check the fluid level in a hydraulic reservoir?
The hydraulics system in your Geoprobesup>u00ae/sup> machine relies on a proper hydraulic fluid level, which you can check by looking at the sight glass on the side of the hydraulic tank (a Geoprobesup>u00ae/sup> Model 54LT is shown), or by checking the dipstick on the hydraulic cap on some units.
Is it bad to overfill hydraulic fluid?
If you overfill it, the fluid expands as it warms up, and if the case is too full, it will push the fluid out the vent.
Where should the reservoir drain plug be located?
The reservoir’s bottom is frequently convex, and a drain plug is included at the lowest point.
What happens when hydraulic fluid is low?
Low fluid levels and improper filtration can lead to air contamination, while fluid contamination can lead to temperature issues, with leaks exacerbating both problems.
Does tractor need to be running to check hydraulic fluid?
IMPORTANT: Never check the hydraulic fluid level with the tractor running; the engine must be turned off to get an accurate reading. Check the oil level in the sight glass (A). It should be between the marks on the glass, with the optimal level just beneath the top mark.
Do you check hydraulic fluid hot or cold?
When the tractor is cold, check the hydraulic fluid level and make sure the vehicle is level. Lower the boom and bucket cylinders, not only to ensure that the machine is in a good position, but also to keep you safe while checking the reservoir.
Can I use ATF for hydraulic fluid?
4. A gallon of ATF is hard to come by for less than $20, but five gallons of hydraulic oil can be had for less than $40; however, ATF is closer in quality to synthetic hydraulic fluid, so it can be considered reasonably priced.
What fluid goes in Lippert leveling system?
Lippert Components, Inc. recommends Dexron III or Mercon 5 automatic transmission fluid (ATF) or a blend of both for the Lippert Dual Sensor Motorized Leveling System, which comes pre-filled, primed, and ready to use straight from the manufacturer.
