FAAC Hinge & Roller Replacement Nationwide

FAAC Hinge & Roller Replacement: The Berkeley Owner’s Guide

FAAC hinge and roller replacement in Berkeley typically runs $340-$620 installed, depending on gate weight, single versus double-wheel carriage, and whether the mounting bracket has warped. We stock FAAC-compatible hinges and rollers for the 400, 402, 422, and S418 series on our Berkeley trucks, and most replacements are completed in under two hours once the part is confirmed. If your gate is sagging, grinding, or catching at the catch post, the hinge or roller is usually the first place we look.

Most Berkeley homeowners notice the problem during our wet season. The roller starts clicking on each open cycle, or the gate develops a visible droop that worsens until the bottom rail drags. In the Elmwood and Claremont neighborhoods, we see this often on swing gates installed fifteen to twenty years ago with original FAAC hardware that was never greased on schedule.

Which FAAC Models This Applies To

FAAC uses several hinge and roller configurations across its product lines, and matching the wrong one accelerates wear on the motor arm.

• 400 and 402 series: These hydraulic swing-gate operators use a heavy-duty adjustable hinge with a 20 mm pin and a grease zerk on the barrel. The roller is typically a single V-groove nylon wheel on a steel bracket. Check the label on the motor housing; if it reads “400” or “402 SBS,” this is your hardware set.
• 422 and S418 series: These operators often ship with a double-wheel roller carriage for gates over 600 pounds. The hinge pin steps up to 25 mm, and the bracket has three bolt holes rather than two. Measure pin diameter with calipers if the label is worn; guessing by eye costs you a second trip.
• OEM versus aftermarket: FAAC-branded hinges and rollers are cast in Italy and carry a premium. We stock quality aftermarket equivalents from American manufacturers that match the load ratings and pin tolerances. For most Berkeley residential gates under 800 pounds, the aftermarket part lasts equally long and costs 30-40 percent less. On commercial-grade 422 installations with continuous cycle counts, we recommend OEM.

The compatibility gotcha: FAAC changed its roller bracket bolt pattern around 2012. A post-2012 400-series roller will not bolt to a pre-2012 hinge plate without drilling new holes, which weakens the masonry or post. We check the manufacture date stamped on the motor housing before ordering.

Signs Your FAAC Hinge & Roller Replacement Is Failing

• The gate droops at the catch post. The hinge barrel has worn internally, allowing the gate leaf to settle. In Berkeley’s clay-heavy hillsides, this settling accelerates because the post itself shifts slightly with winter moisture cycles.
• Grinding or clicking on open/close. The roller bearing has lost its seal and ingested grit from the driveway. Once the bearing races pit, lubrication cannot restore smooth operation; the roller needs replacement.
• The motor strains or overheats. A seized hinge or flat-spotted roller increases the load on the FAAC hydraulic pump. The motor draws more amperage, runs hotter, and eventually faults out. We log the amp draw with a clamp meter; if it is 20 percent above spec, the mechanical hardware is the culprit, not the motor.
• Visible rust weeping from the hinge barrel. The internal grease has washed out, usually from a missing or cracked zerk fitting. Berkeley’s marine air accelerates this; we see it within eight to ten years on unprotected hardware.
• The gate catches or bounces at the end of travel. A worn roller develops flat spots or the axle bolt loosens, causing the gate to hop rather than roll. This misaligns the FAAC limit switches and can damage the operator arm over time.

Replacement Cost & What’s Included

What drives the range: gate weight determines whether you need standard or heavy-duty hardware; double gates require matching pairs; and if the mounting surface has rotted or the bracket has twisted, we replace that too rather than bolt new parts to bad geometry. The price we write on the estimate is the price on the invoice. Under Haven Standard Clause 1, you get that number before we pick up a tool. Parts carry a one-year warranty; labor is covered by our 365-Day Done Right Promise.

DIY or Call Us?

There is a safe middle ground here. You can inspect the hinge zerk fitting for grease, check whether the roller spins freely by hand with the gate in manual release, and photograph the motor label so we know which series you have. What you should not do: remove a loaded hinge pin from a gate that is not properly supported, or attempt to realign a sagging gate without knowing whether the post itself has shifted. A 400-pound gate leaf on a worn hinge is a genuine crushing hazard.

We carry FAAC-compatible hinges and rollers on our Berkeley trucks, and we document every installation with photos of the old part, the new part number, and the torque settings on the mounting bolts.
