Volvo 4300B to L70D: engines, steering and loads

4300B: the earlier four-cylinder machine has its own steering system

Volvo's archive places the BM 4300B in 1984–1986 production and identifies its TD 45 B engine. The later L70 names should not turn that earlier loader into an interchangeable version of the same machine. Volvo specifically records the 4300B's new load-sensing hydrostatic steering system.

During an inspection, distinguish steering response from bucket and lift-arm response; a complaint about one function does not establish the condition of the other.

Its archive also separates straight-ahead tipping load from the lower full-turn load. That distinction matters when a loading cycle includes articulation toward a truck. The straight-ahead figure is not the capacity available throughout the turn.

Keep the steering position attached to any capacity comparison, together with the fitted bucket and tires.

L70B: identify the engine as well as the loader badge

The L70B archive's 1994 specification names TD 61 GD, while its equipment description separately offers the low-emission TD 63 KDE engine. An engine photograph and identification plate can therefore settle something that the L70B badge alone cannot. A parts request should carry that engine designation instead of assuming every L70B has the engine in the main specification row.

Contronic monitoring, load-sensing working hydraulics, the Care Cab and TP linkage belong to this generation's description. The later L70D's Contronic II and Care Cab II labels should not be applied backwards. Test the installed monitor and identify its warning indications using the L70B information.

Likewise, its operating-weight range describes different equipment arrangements; it is not evidence that every used machine weighs the single reference-table figure.

L70D: distinguish brake circuits, rated power and maximum power

The L70D sheet describes a dual-circuit service brake with nitrogen-charged accumulators. A cab switch preselects transmission declutching during braking. Its parking brake is a separate mechanical drum on the front-axle input shaft.

Identify which brake function a seller is demonstrating; stopping with one control does not demonstrate every circuit.

Engine speed also changes the power comparison. Volvo gives a maximum net output and a separate rated-speed net output, while listing gross output alongside each. The standard configuration and optional noise-reduction kit have different net entries.

The lower rated-speed figure is not a second engine.

For lifting, Volvo separates pin-on and hook-on buckets and lists full-turn tipping loads for each arrangement. Bucket fill factor can change the actual carried volume. Identify the attachment and material before comparing those rows or using a tipping figure as a payload allowance.
