Professional chain service – split and rivet Mercedes duplex/double-row chains without removing the timing cover; precise peening for OE-quality joins.

Broad engine coverage – works with popular MB petrol/diesel families: M271/M272/M273 and OM601–OM617 (4 mm chain bolts).

OE-reference compatibility – alternative to MB/Miller 9312A; replaces MB tool nos. 112589096300, 602589003900, 602589023300, 602589024000.

Shop-ready durability – hardened components and guided thrust pieces help ensure consistent, repeatable rivets job after job. (General capabilities shown across equivalent kits.)

Organized kit – blow-mold case keeps drivers, anvils, and links sorted for fast setups in bay or field.

Renew timing chains like a pro. The Oni Tools Timing Chain Riveting & Separating Kit is engineered to split and re-join Mercedes-Benz timing chains with OE-level accuracy—no complete front cover teardown required. The separating tool cleanly breaks the old chain; the riveter forms precise peened heads for a secure, factory-style connection on duplex/double-row and Simplex chains. The kit targets core MB engines used across decades—M271, M272, M273 gasoline and OM601, OM602, OM603, OM615, OM616, OM617 diesels with 4 mm chain bolts—and cross-references common OE/Miller part numbers (9312A, 112589096300, 602589003900/023300/024000) for easy lookup. Built from hardened tool steel and packed in a blow-mold case, it’s ideal for professional technicians and advanced DIYers tackling timing chain renewal, guide service, and cam timing work on classic to modern MB platforms.
