ACEBRI PTO Clutch replacement for Ogura GT1A-EH (53462700) — 1.125" crank, 6-groove CCW heavy-duty fit

ACEBRI PTO Clutch (GT1A-EH compatible) is a direct-fit replacement clutch assembly designed to restore reliable blade engagement on compatible Husqvarna, Jonsered and other lawn tractors.

This heavy-duty PTO clutch from ACEBRI is engineered to match the fit and function of the Ogura GT1A-EH series (OEM 53462700) and several factory part numbers used by Husqvarna, AYP, Craftsman, Ferris and Dixie Chopper. Built with the same crankshaft size and pulley configuration required by many zero-turn and garden tractors, it provides the correct rotation and torque ratings to operate mower blades consistently while fitting the listed model numbers without modification.

Will this clutch fit my mower model?

The ACEBRI PTO clutch is a replacement for numerous part numbers across brands; compatibility depends on your tractor’s specified clutch dimensions and OEM references. Compare the listed replacement numbers and mower model list to your machine’s manual or existing clutch stampings to confirm fit.

• Directly replaces Ogura GT1A-EH (53462700) and Dixie Chopper 500144.
• Interchanges with Husqvarna/AYP/Craftsman part numbers like 174605, 179335, 414737 and 532 series.
• Fits many Husqvarna and Jonsered models such as GTH 2548, LGT2554, YTH220, Z454, LT2223 series and others.
• Check crankshaft diameter (1.125") and pulley count (6) for exact fit.

What are the key mechanical specifications I need to know?

This clutch assembly is built to match the mechanical footprint most service manuals expect: crankshaft fit, pulley groove count and rotation direction. These figures determine whether the unit will mount correctly and deliver safe engagement for cutting decks.

• Crankshaft bore: 1.125 inches for a press-fit installation.
• Pulley grooves: 6 to match the mower drive belt configuration.
• Rotation: counterclockwise (CCW) as viewed from shaft end.
• Rated torque: 110 (units per OEM specification) for blade engagement reliability.

How do I address clutch engagement issues and brake shim adjustments?

Wear changes the clutch air gap over time; if the clutch engages when cold but slips when hot, the brake shim may need removal to restore proper clearance. Always perform adjustments with the engine off, keys removed and clutch disengaged for safety.

• Remove brake shim only if heat-related engagement problems appear.
• Confirm engine is off and ignition key is removed before servicing.
• Follow service manual torque and clearance specs when reassembling.
• Contact ACEBRI support for guidance on shim removal and gap tolerances.

How do I replace OEM numbers or verify interchangeability?

ACEBRI lists the OEM numbers this clutch replaces to simplify selection; match any of those numbers stamped on your original part or listed in your parts manual. If in doubt, measure your current clutch and consult our support team with photos for confirmation.

• Common replaceable part numbers: 174605, 179335, 414737, 532174605, 532179335 and others.
• Other brand equivalents include Ferris 5100417 and Ogura GT1A-EH01 references.
• Seller offers model consultation—email ACEBRI shop for verification before purchase.
• Keep your tractor’s model and serial number handy for faster support.
