The ATC W470589015900 Piston Ring Compressor (OEM alternative to W470589015900 / J-47386) enables safe, uniform compression of piston rings for smooth insertion into DD15 and DD16 cylinder bores. Prevents ring breakage, bore scoring, and piston damage during heavy-duty engine rebuilds and overhauls.

The Critical Risks of Improper Piston Ring Compression in DD15 & DD16 Engines

Detroit Diesel DD15 and DD16 engines power Class 8 trucks and heavy equipment, but damaged rings or scored bores from poor compression lead to oil consumption, blow-by, and catastrophic failures.

• Ring breakage – Uneven compression snaps rings, requiring $1,000–$2,500 piston/ring sets
• Bore scoring – Rings catch on installation, leading to $2,000–$5,000 cylinder honing
• Oil consumption – Broken rings cause blow-by, costing $1,500–$4,000 in repairs
• Downtime losses – Manual struggles extend rebuilds 2–4 hours, adding $400–$800 labor
• Piston damage – Misaligned rings score pistons, totaling $2,000–$4,000
• Engine failure – Untreated issues demand full overhaul ($10,000–$20,000)
