Engine piston ring set for Toyota Tercel

This engine piston ring set, part number 6140, is built for the 1980-1988 Toyota Tercel with a 3.051-inch engine bore and standard size dimensions. It is specified for the 4-cylinder application and uses grey iron and steel rail materials with phosphate and chrome surface treatments.

  • Fits 1980-1988 Toyota Tercel, N/A.
  • Standard size piston ring set for a 3.051-inch bore.
  • Grey iron top and second rings for consistent sealing performance.
  • Steel rail and stainless expander oil ring design.
  • Phosphate and chrome surface treatments for added wear resistance.

Detailed product overview

Part number 6140 is an engine piston ring set for Toyota Tercel applications listed from 1980 through 1988. The fitment data identifies a 3.051-inch bore, 1.5 mm top and second groove dimensions, and a 2.8 mm first oil groove, making this a direct match for the specified standard-bore engine configuration. The ring package combines grey iron top and second rings with a steel rail and stainless expander oil ring, along with phosphate and chrome surface treatments to support ring seating and cylinder wall contact.

This part cross-references Monroe Shocks & Struts (e.g., 10410X, 12151P) for the same application.

What this part helps address

  • Low compression caused by worn or fatigued piston rings.
  • Excessive oil consumption from ring wear or poor sealing.
  • Blow-by from reduced cylinder sealing.
  • Loss of ring tension in standard-bore engine rebuilds.
  • Uneven sealing in 4-cylinder Toyota Tercel engine service.

Installation notes and tips

Verify the engine bore, groove dimensions, and standard-size specification before installation. Match the ring set to the cylinder bore and ring groove measurements listed in the fitment data for the Toyota Tercel. Proper cylinder preparation and ring end-gap checking are important during engine assembly.

Quality assurance

Use the fitment and dimensional data to confirm application accuracy before assembly. Part number 6140 is specified for the listed Toyota Tercel engine configuration.
