The BendPak 5570851 hydraulic hose is the direct replacement for the BendPak lift it came off of. This is the genuine BendPak part — same fit and same working specification as the one already on your lift. Ordering the BendPak hydraulic hose from us gets you the OEM piece that matches the lift, not an aftermarket knock-off that is close but not the same.

Specifications

• Part number: 5570851
• Brand: BendPak
• Type: Genuine OEM hydraulic hose

Not every hydraulic problem is the cylinder. A lift that lowers itself overnight usually has a lowering valve that won't seat or a leaking check, not a bad seal. A lift that jerks or won't reach full height can be a tired pump or a flow valve out of adjustment. And a hose that's cracked near the crimp will spray under pressure — a real hazard, not just a mess to mop up.

The power unit bundles the motor, pump, reservoir, and valves into one hangable box, usually bolted to a column or a pump stand. Press up and the motor spins the pump, which draws fluid from the reservoir and sends it to the cylinder; release, and the dump valve routes it back. The single spec that matters most is voltage — 110 versus 220 — because the wrong one turns the whole unit into a paperweight.

Replacing your hydraulic hose

Replacing a hydraulic cylinder comes down to relieving all pressure, capping the lines so nothing gets contaminated, getting the old cylinder out and the new one in, then bleeding the air and leak-checking under load. The exact removal path differs by lift style, and skipping the bleed leaves the lift spongy. Because a cylinder holds a vehicle in the air, the full procedure is worth following start to finish. Full step-by-step: how to replace a car lift hydraulic hose.

Find the right part for your lift

Landed here but not 100% sure it is your part? Grab the model and serial from the data plate and open our parts lookup for the visual breakdown — the manufacturer-style drawing with every item numbered so you can match yours exactly. Plate missing? our guide to finding your model number helps, and we identify lifts from photos every week if you would rather ask.

Signs of a hydraulic problem

Pull the reservoir cap and look at the fluid. Clear amber (or clean red for ATF) is good; milky or foamy means water has gotten in and the pump is aerating; dark and gritty means the system is wearing and the filter is loading up. Fluid condition tells you as much about the hydraulic health of the lift as any single part will.

Parts commonly replaced at the same time

Hydraulic parts travel in company: a leaking cylinder often needs a seal kit, a tired hose, and a fluid change all at once. Since you are relieving pressure and bleeding anyway, do the related wear items in the same visit. Tell us your model and we will pull the matching seals, hose, and oil.

Hydraulic fluid

The usual fill is ISO-32 hydraulic oil, with some legacy lifts running Dexron ATF; confirm which your lift uses before topping off and keep the two separate. Bleed after filling and check the level again once the air is out — and see your manual for the exact capacity, which is model-specific.

Safety notes

The failure mode that hurts people is slow drift-down from a bad seal or trapped air, so never leave a hydraulic repair half-bled. Support the lift on its mechanical locks while you work, relieve pressure before opening the system, and cycle it several times empty — watching for drift — before a vehicle goes on it.

Before you order

A little prep prevents a wrong order: confirm model and serial, measure hoses and note fitting sizes, and check whether a reseal solves it before buying a complete cylinder. Budget for oil and bleeding as part of the repair. We will confirm the right part for your production run before it ships.

Check your lift's serial before ordering

The most common reason a lift part comes back is not a defect — it is a revision mismatch. Manufacturers change sub-parts between production runs while keeping the same lift model name, so "it fits my lift model" is not always enough. The model plate carries the serial number that pins your lift to a specific run, and that is the number that settles which version of this part belongs on your lift.

Can't find the plate? Measure the old part — overall length, bolt-hole spacing, thread size on anything threaded — and photograph it from a couple of angles. Send that with your lift's brand and rough age and we will match it against the parts breakdowns we service from every week.
