FAQ

Q1: How do I verify these rings fit my Perkins 404D-22 engine?
A1: Verify your engine’s serial number and cylinder bore size. This set is specifically for an 84mm STD (Standard) bore. If your block has been rebored, you will require an oversize (e.g., 0.50mm or 1.00mm) ring set. Also, confirm if your engine uses a “Keystone” (tapered) top ring or a “Rectangular” ring; this set typically covers the common rectangular profile.

Q2: What is the correct installation procedure for these rings?
A2: Installation requires a piston ring compressor. Ensure rings are installed with the correct orientation (top side up) and that ring gaps are staggered at 120 degrees around the piston. Always lubricate the rings and cylinder bore with clean engine oil before assembly. Refer to the Perkins service manual for specific torque and gap specifications.

Q3: Can I use this ring set in a high-hour engine without replacing the cylinder liner?
A3: It is highly recommended to measure the cylinder bore for taper and out-of-roundness before installation. If the bore wear exceeds the manufacturer’s service limit (typically 0.005-0.010 inches), the new rings may not seat properly, leading to high oil consumption. For best results, install new rings in conjunction with a new or reconditioned cylinder liner and new piston.
