The Rotary FJ7813-13 replacement part is the direct replacement for the Rotary lift it came off of. Cross-referenced as ALS-7536-38, it is the genuine Rotary part — same part number, same fit, and same working specification as the one already on your lift. Ordering the Rotary replacement part from us gets you the OEM piece that matches the lift, not an aftermarket knock-off that is close but not the same.

Most lift failures do not start with the big components. They start with a part like this one — something small that wore quietly until the load found the weak point. A worn pin lets a sheave wobble, the wobble chews the cable, and now a cheap part has turned into a cable job. A sticking valve, a thinned bushing, a fatigued spring: each one is a few dollars of steel guarding components that cost hundreds. Replacing wear parts on schedule — instead of when they announce themselves — is the cheapest maintenance a lift ever gets, and it is the difference between shops that fix lifts and shops that keep replacing the expensive parts downstream of the cheap one.

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.
When one wear part is finished, look hard at what it touched. Metal shavings are the tell — where there are shavings, something has been grinding. Check the mating surfaces this part rode against for scoring, ovaled holes, and rounded edges, because a new part installed against a chewed-up mate wears out on an accelerated schedule and takes the blame for it.
Do not put a known-worn part back in because it looks serviceable enough — on a lift, “probably fine” is carrying somebody’s vehicle over somebody’s head. If it was worn enough to remove, it is worn enough to replace.

About this fj7813 dampening spacer
Sourcing the correct fj7813 dampening spacer 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 fj7813 dampening spacer 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
Placing an order online is the fastest path — add to cart, check out, done. If the shop needs a purchase order, net-30 terms, or a formal quote for a fleet-service contract, our accounts team handles those via email at [email protected] or by phone at 800-674-9302. Volume pricing on the fj7813 dampening spacer kicks in at 10+ pieces on the same order for common wear items. Ask about the volume rate specifically before you check out — many fleet buyers stock 6-12 pieces at a time and the discount is meaningful over that shelf life.
Warranty coverage
Consumables and wear parts like this are covered under the manufacturer defect warranty for twelve months. Because the fj7813 dampening spacer is a component that eventually needs replacement in normal operation, warranty coverage specifically addresses failure due to manufacturing defect, not failure due to normal end-of-life wear. Our team can help distinguish between the two on a phone call if there is any question after installation — call 800-674-9302 and describe the failure pattern; we will tell you honestly whether it looks like a warranty case.
Cross-reference & fitment
Cross-reference on the fj7813 dampening spacer is straightforward: match the OEM part number from the lift's parts breakdown against the number on your original invoice. If the numbers match, the component fits. If your lift's parts breakdown lists a superseded or alternate number, we accept the superseded value on the phone as confirmation of fit. When a manufacturer has issued a running change during production, we track the change in our catalog so ordering by the older number automatically pulls the current-spec replacement.
