Liftmaster K11-8062, INTERMEDIATE SHAFT
The LiftMaster K11-8062 intermediate shaft is a drive-train shaft used in select LiftMaster barrier arm operator systems. In a barrier operator, the intermediate shaft helps carry motion through the internal drive assembly so the barrier arm can move consistently and stay properly timed with the rest of the mechanism.
This part is most often associated with the LiftMaster BG790 barrier gate operator family and related perimeter access applications. It is not a generic shaft. The correct replacement depends on the operator model, shaft length, bearing support, keyway, and the surrounding drive components.
Common Replacement Reasons
- Barrier arm movement is rough or uneven
- Shaft is bent, worn, or corroded
- Bearing or sprocket area shows excessive play
- Drive assembly is being rebuilt after mechanical wear
- Arm linkage does not stay properly aligned

Technician Note
On a barrier operator, shaft alignment is critical. If the arm has been struck or the gearbox area has shifted, inspect the complete drive path instead of replacing only the shaft.
Before Ordering
- Match the manufacturer part number to the operator parts diagram before ordering.
- Compare the shaft, bearing, bushing, or gasket dimensions against the removed part.
- Check the operator model, series, and generation because similar LiftMaster mechanical parts may not interchange.
- Inspect nearby collars, sprockets, chains, keys, fasteners, and bushings for wear before reassembly.
- For commercial gate or barrier operators, have a qualified technician handle service if the gate movement is unsafe or the drive system is under load.
Professional Advisory
Commercial gate and barrier operator drive parts should be serviced with the gate secured, power disconnected according to the operator manual, and all safety devices left in proper working order. Do not bypass entrapment protection or operate a damaged gate system to test a mechanical repair.
Product Questions & Answers
What operator is K11-8062 commonly used with?
The most common confirmed application is the LiftMaster BG790 barrier gate operator.
Is K11-8062 the same as K11-8061?
No. K11-8062 is an intermediate shaft, while K11-8061 is a main shaft. They are different drive parts.
What related numbers should I compare?
Common related numbers include 11-8062, 118062, G118062, and LM-K11-8062.
Can this part fix a barrier arm that shakes?
It may help if the original shaft is worn or bent, but bearings, sprockets, arm hardware, and linkage should also be inspected.
Why should the parts diagram be checked?
Barrier operator shafts can be similar in appearance but have different lengths, machined sections, or keyway locations.
