Bellhousings accommodate non-standard dimensions

A JBJ Techniques product story
Edited by the Engineeringtalk editorial team Jul 24, 2000

JBJ's selection of hydraulic pump adaptors for close coupling hydraulic pumps and diesel engines now even accommodates engines with flywheel and housing conforming to SAE dimensions

From the extensive selection of hydraulic pump adaptors for close coupling hydraulic pumps and diesel engines available from JBJ Techniques, even engines with flywheel and housing conforming to SAE dimensions can now be accommodated, using a bellhousing and coupling arrangement.

Special adaptors are also used for prime movers which do not conform to accepted dimensions, such as small petrol engines.

Seemingly limitless combinations of hydraulic pumps and diesel engines can be close coupled.

Front mounting adaptors for air-cooled diesel engines feature a front PTO facility.

The drive couplings are individually tailored to suit.

A range of engines are covered by these adaptors, including Deutz, Lombardini, Lamborghini, Ruggerini, Same and VM.

A range of clutches is also available with a hydraulic pump adaptor in place of an output shaft.

The pump adaptors take the same form as offered on JBJ's AM multiple pump drive units (see below), but the selection may be restricted by certain combinations of pump and clutch.

Models in the AM series of hydraulic pump drives available allow two or more hydraulic pumps to be operated simultaneously from a single prime mover.

Most models in the range can be supplied as a basic model for independent mounting, with an over-centre industrial clutch, or with housing and coupling connections for a diesel engine.

The pump housing is made from cast iron.

The straight-tooth gears and the shafts are both case hardened steel.

Viton PTFE seals are used on the input shaft.

The pumps drives can be modified for connection to diesel engines, with flywheel and flywheel housing dimensions according to SAE standards.

Correct choice of lubricant is dependent on ambient temperature.

Gear lube oils with EP additive and a minimum viscosity index of 95 are recommended.

The oil should be replaced after the first 50 hours and thereafter every 1000 hours or 12 months.

Because the oil working temperature must not exceed 105C, for some applications, a cooling system is recommended and this is available on many of the models in the range.
