6840L-70SV2 Left Straddle Leg Adapter for ESCO 70SV2 Excavator Buckets

Full Description

The 6840L-70SV2 is a left-hand straddle-leg weld-on bucket adapter referenced to the ESCO SV2 70-size tooth system. Catalog documentation identifies it as a Type 4CN, 1-1/2 top-leg straddle or corner adapter. It is intended for installation at the left outer tooth position of a compatible bucket lip, where the upper and lower legs straddle the lip structure before the adapter is welded into position.

This component provides the mounting nose for a compatible 70SV2 tooth point. The adapter itself is not a complete tooth assembly. Tooth points, pin assemblies, locks, installation tools and other hardware must be confirmed separately and should not be assumed to be included in the quoted supply.

Published catalog geometry for 6840L-70SV2 includes a nominal 89 mm (3.50 in) lip thickness, 419 mm (16.50 in) top-leg length, 197 mm (7.75 in) bottom-leg length, 214 mm (8.44 in) adapter width, 30-degree ramp angle and 10-degree nose angle. Catalog weight is approximately 96 kg (212 lb). These values are useful for preliminary identification, but the actual supplied part and bucket lip should be measured before welding or bulk ordering.

The part is cataloged for heavy bucket applications under descriptions including HEX, Backhoe and HFS. These are equipment categories rather than confirmed machine-model applications. Fitment should be determined from the existing adapter number, bucket identification, lip thickness, lip profile, left-hand mounting position and the installed tooth system.

This aftermarket replacement is intended for distributors, importers, mine maintenance teams, bucket repair companies and contractors sourcing ground-engaging components by reference number. Buyers should provide the required part number, equipment details, bucket or attachment number where available, photographs of the existing adapter and tooth, and critical installation measurements.

The supplied product is not represented as an original ESCO component. ESCO and SV2 references are used solely to identify the applicable tooth-system family and dimensional configuration.
