Rotor Feed Nut - FMC - 90077 — a direct-fit replacement replacement hardware. Ordering the replacement hardware 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: BL-50002
- Type: Genuine OEM replacement hardware
On lift hardware, fit is the whole job. A pin is not a rod of roughly the right diameter — it is a specific length, a specific fit in its bore, and a specific way of being retained, whether that is an e-clip groove, a cotter key hole, or a shoulder. A bushing is a precise interference in its housing and a precise clearance on its shaft. Manufacturer-spec hardware carries all of those dimensions; the hardware-aisle stand-in carries some of them, and the missing ones become play, wobble, and premature wear. This is a spec-correct replacement for the assembly it belongs to — it goes in the way the original came out, retained the way the original was retained.

Not sure this fits? Here's how to check
Pull the number off your lift's model plate first — model and serial both. Manufacturers run mid-cycle revisions that keep the model name but change hardware, so two lifts with the same name on the column can take different parts. The serial is what removes the guesswork.
Second check: compare the old part against this listing before you order. Length, mounting pattern, and thread sizes tell most of the story. If anything doesn't line up, or if the old part is too worn or broken to measure, call us with photos — we work on these lifts every week and can usually confirm fit from a picture and the lift's serial faster than you can dig through a parts diagram.
Lay the new piece against the old before installing: length, diameter, groove and hole positions, thread pitch. If the old part is too worn to compare against, check the new part in its bore or against its mate by hand — it should fit the way a machined part fits, snug and smooth, not loose and not forced. Replace the retaining clips and keys while you are there; they are one-use money.
Retention is not optional. A pin without its e-clip, cotter key, or bolt is a pin working its way out under vibration, and what it drops depends on where it lives. If the retainer came off damaged, replace it — never spring a used clip back on and call it held.

About this 90077 rotor feed
Sourcing the correct 90077 rotor feed is not the spot a shop wants to gamble. This piece sits inside a load path the lift manufacturer engineered to specific tolerances, and a substitute that looks close but is off by even a small margin can transfer load onto a neighboring component that was not designed for it. We stock this exact part to the OEM specification the original manufacturer publishes, which is why techs who have been through a bad aftermarket cycle keep coming back to us for the same replacement whenever their next need comes up.
Technical specification & installation notes
Technical specification matches the OEM published dimensions to within manufacturing tolerance. When a shop installs the 90077 rotor feed correctly, the lift returns to factory-rated performance immediately — no break-in period, no cycle-count adjustment required. The lift's safety systems (mechanical locks, hydraulic pressure relief, and electrical interlocks) treat a correctly-installed replacement exactly as they would treat a factory-original component during initial commissioning. That parity is what lets us honor warranty coverage without asking for the lift's full operating history.
Shipping & ordering
Freight covers the continental United States on all standard orders. We ship UPS or FedEx ground for parts under 30 lb; heavier assemblies quote at published carrier rates. International orders on the 90077 rotor feed require a freight quote — email dimensions, weight, and destination country to [email protected] and we return a rate within one business day. Alaska, Hawaii, and US territories quote at published rates and typically take five to ten business days depending on carrier and destination.
Warranty coverage
Return policy on the 90077 rotor feed follows our store-wide standard: all parts sales are final; exchanges only if the piece arrives defective. In the case of a defective delivery, ship the failed piece back to us at your cost, we verify the defect on receipt, and ship a replacement at ours. Wrong-item deliveries where we made the shipping error follow a different path — we reimburse the return shipping cost and cover freight on the correct part. Contact [email protected] with the order number to start either process.
Cross-reference & fitment
Fitment on the 90077 rotor feed is verified against the lift serial number when the order comes in. Even inside one manufacturer's catalog, a lift model built in one production year can carry subtle revisions from the same model built two or three years later. Sending us the lift serial number when you place the order — either in the order notes or in a follow-up email — lets us verify the piece against that specific serial's parts list. That five-minute step catches revision mismatches before shipping and prevents the delay of an incorrect delivery.
