20176B-02000 Forklift Truck Support Hydraulic Cylinder

Cab Tilt Locking

On forklifts with tiltable cabs (common on 5+ tonne models for engine access), the support cylinder holds the cab in the upright operating position. If this cylinder leaks or loses pressure, the cab can tilt forward unexpectedly — a serious operator safety hazard. The support cylinder must hold the cab weight (200–500 kg) against vibration and inertial forces during travel, cornering, and braking.

Mast Pivot Stabilisation

On some heavy-duty forklifts, a support cylinder provides supplementary lateral stabilisation to the mast pivot mount. While the primary tilt cylinders control the fore/aft angle, the support cylinder resists side-to-side rocking of the mast under uneven loads. This is particularly important on rough-terrain forklifts where ground irregularities create lateral forces that the tilt cylinders alone cannot fully absorb.

Auxiliary Equipment Positioning

Battery trays, engine hoods, counterweight access panels, and fuel tank covers on larger forklifts use small support cylinders to hold these components in their open or operational position. These are typically the lightest support cylinders on the vehicle — Φ30–Φ50 bore with 50–200 mm stroke — but their failure creates maintenance access problems that prevent routine servicing of the vehicle.

How do I verify that this part number fits my forklift?

Check the original cylinder for a stamped or engraved part number. If the number matches 20176B-02000, the Korea Ever-Power replacement is a direct fit. If the number is different but the cylinder performs the same support function on a compatible platform, measure the six critical dimensions (bore, rod, stroke, closed length, port thread, pin bore) and compare them with the 20176B-02000 specification. Contact Korea Ever-Power with your measurements — our engineering team will confirm whether the 20176B-02000 is a direct replacement or whether a custom-dimensioned cylinder is needed.

My support cylinder leaks but the forklift still operates — do I need to replace it urgently?

Yes. A leaking support cylinder should be treated as an urgent safety issue, not a cosmetic problem. If the cylinder supports the cab tilt mechanism, a leak means the cab could descend unexpectedly — a serious operator injury risk. If it stabilises the mast frame, reduced support pressure allows structural movement that accelerates wear on mast rollers and pivot bearings, creating a cascading maintenance problem. Even if the leak is small (seepage rather than a stream), the loss of oil reduces the holding force proportionally. Replace the cylinder at the earliest scheduled maintenance opportunity — do not wait for the next annual service.

Can I upgrade the seal specification when ordering the replacement?

Yes. The Korea Ever-Power replacement uses the same bore and rod dimensions as the original, so any seal profile that fits those dimensions can be specified. Common upgrades include: switching from NBR to FKM (Viton) for cold-storage or chemical-exposure environments; switching from standard polyurethane to Hallite PTFE-based rod seals for reduced friction and longer static holding life; or adding a secondary dust wiper for outdoor applications. The seal upgrade does not change the cylinder's external dimensions or mounting — it is an internal quality improvement that extends service life.

Do you stock this part number or is it manufactured to order?

Manufactured to order. Support cylinders are lower-volume items than lift or tilt cylinders, so maintaining inventory for every part number is not practical. However, because the 20176B-02000 dimensional data is in our validated database, the engineering review step is eliminated — production can begin as soon as the order is confirmed. Typical lead time for a single replacement unit: 2–3 weeks. For fleet orders (10+ units), discuss blanket order arrangements with annual call-off scheduling for faster delivery on repeat orders.

Ordered the 20176B-02000 for a HELI CPCD30 we've had in our yard for 11 years. Original part was discontinued, dealer quoted us 8 weeks and a ridiculous price for a "special order." Ever-Power shipped in 16 days. Bolted right in — pin holes, port threads, stroke, everything lined up perfectly. No shimming, no adapter fittings. We're running it 10 hours a day now, three months in, zero leaks. Already placed a second order for the tilt cylinders on the same truck.

Good quality cylinder. Finish is clean, chrome is smooth, pressure test certificate was included in the box. I requested NOK seals and they confirmed the exact part numbers before production, which I appreciated. Only reason for 4 stars instead of 5: packaging could be improved — the cylinder arrived with minor surface scratches on the barrel paint from shifting inside the crate. Functionally perfect, but if you're reselling to an end customer who cares about cosmetics, ask them to add foam padding.

We service a mixed fleet — Toyota, Hyster, HELI, Hangcha — and sourcing support and auxiliary cylinders for the Chinese-brand trucks has always been a headache. Started working with Ever-Power last year for cab support cylinders and mast stabiliser cylinders. So far we've ordered 23 units across 6 different part numbers. Every single one has been a correct-fit drop-in replacement. The engineering team is responsive — we send them measurements and photos on WhatsApp and usually get a drawing confirmation back within 24 hours. Turnaround averages about 18–20 days door to door.

Needed a cab tilt support cylinder for an older forklift where the original supplier no longer exists. Sent the old cylinder by courier to Ever-Power, they reverse-engineered it and sent me a drawing within a week. I approved, and the replacement arrived 3 weeks later. Fit was exact. I specifically asked for Parker seals and FKM compound because the truck works outdoors in the Netherlands — rain, frost, the works. Six months later, holding pressure is still perfect. No drift at all. Would recommend for anyone dealing with obsolete cylinder part numbers.

Ordered 2 pcs for our warehouse forklifts. Product quality is very good — you can tell the machining is proper, bore finish is mirror-smooth. Communication was a bit slow at the start (time zone difference I think) but once we got connected with the right engineer things moved fast. Price was about 40% less than what our local dealer quoted for the equivalent OEM part. Will order again when the other trucks need cylinder replacement.
