The Rotary FJ6138 lift adapter is the direct replacement for the Rotary lift it came off of. This is the genuine Rotary part — same fit and same working specification as the one already on your lift. Ordering the Rotary lift adapter 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: FJ6138
• Brand: Rotary
• Type: Genuine OEM lift adapter

The carriage is the steel weldment that rides up and down the column carrying the arms. It takes the full lifting load through its slide blocks and its arm pins, and it's where cracks and wallowed-out holes show up on a hard-worked lift. A carriage with an egg-shaped arm-pin bore lets the arm rock; slide blocks worn to nothing let the carriage ride steel on steel and cock in the column.

Replacing your lift adapter

A slide-block replacement gets the carriage riding square in the column again instead of steel-on-steel. Pull the carriage down, swap the worn blocks, and confirm the carriage moves freely without cocking. It's methodical work with a clear sequence, spelled out in full in the step-by-step guide.

Find the right part for your lift

Want to be sure before you buy? Pull the model and serial off your lift's plate and open our Rotary parts lookup to open the exploded parts breakdown for your model — find your part on the drawing and you know it fits. New to finding your model number? our guide to finding your model number covers it, or send a photo of the plate and we will read it for you.

Signs this part is worn out

The structural condemn list: pads crushed, torn, or oil-soaked; adapter lips bent or cradles spread; pin holes egg-shaped; arms bent; slide blocks worn to steel-on-steel; cracks at any load-bearing weld; loose anchors or missing retainers. These parts carry the vehicle directly, so any one of them shifting, rocking, or cracking is a reason to swap the part before the next car goes up.

Parts commonly replaced at the same time

Handle the companions while you are at it. The hardware that mounts a worn pad or adapter is often worn too, and the other contact points are on the same clock. One order for the full set keeps the lift even and saves a second trip. Tell us your lift and we will kit it.

Safety notes

The safe grip between lift and vehicle lives in the pads, adapters, and arm hardware — and every one of them wears. A crushed pad or a wallowed-out pin bore is a slip waiting to happen. Change them at the first sign of damage, secure all hardware to spec, and never trust a load to a worn contact point.

Before you order

Ordering tip: contact and locating parts are model-specific and usually come as sets, so count what you need and read the plate before you buy. If the pads are crushed, the pins and hardware around them are often due too — ask and we will tell you what commonly goes together on your lift.

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.
