Application Heavy cylinder heads of large diesel engines can be safely and easily clamped onto the extremely stable WV Cylinder Head Stand to perform maintenance and repair work. If required, the WV can be also used for storing a spare cylinder head. Features The cylinder head mounted on the WV Cylinder Head Stand can be rotated through 360° and locked in any position which is most suitable for the work to be performed. A removeable tray provided in the bottom frame collects any liquid from the cylinder head. Antivibration pads are provided at the bottom frame which are to be secured to the floor so that the stand cannot fall over when mounting and servicing the cylinder head.

Application The VDS1A is designed to reface valve seats of the engines of motorcycles, cars and light commericial vehicles. Features The VDS1A refaces the valve seat in a lathe-type facing action. A gear head includes a feed mechanism for continous outward transverse motion of the single point turning tool when the VDS1a is rotated around a pilot inserted in the valve guide. The direction of the feed motion is defined by an exchangeable adapter head screwed to the gear head. A steady rest which is mounted on the cylinder head stabilizes the VDS1A below the crank handle. The steady rest eliminates runout when rotating the VDS1A around the pilot. As a result, the seat is refaced to concentricity with the valve guide under the correct seat angle.

Application The VDS2 is designed to reface valve seats of the engines of trucks. heavy construction vehicles and small ships. Features The VDS2 refaces the valve seat in a lathe-type facing action. A gear head includes a feed mechanism for continous outward transverse motion of the single point turning tool when the VDS2 is rotated around a pilot inserted in the valve guide. The direction of the feed motion is defined by an exchangeable adapter head screwed to the gear head. A steady rest which is mounted on the cylinder head stabilizes the VDS2 below the crank handle. The steady rest eliminates runout when rotating the VDS2 around the pilot. As a result, the seat is refaced to concentricity with the valve guide under the correct seat angle.

Application The VD2 is designed to reface valve seats of the engines of trucks. heavy construction vehicles and small ships. Features The VD2 refaces the valve seat in a lathe-type facing action. The tool head includes two inclined slideways for refacing 30° and 45° valve seats. A single point turning tool is clamped to tool slide guided in the respective slideway. When the VD2 is rotated around the pilot by hand, the turning tool travels in a circle around the valve seat with continuous outward transverse feed motion under the correct seat angle. A steady rest which is mounted on the cylinder head stabilizes the VD2 below the crank handle. The steady rest eliminates runout when rotating the VD2 around the pilot. As a result, the seat is refaced to concentricity with the valve guide under the correct seat angle.

Application The Hunger RDS is designed to precision machine the seat ring bores in cylinder heads to produce smooth and closely fitting contact surfaces for oversize seat inserts. Features The RDS is equipped for counterboring as well as for facing the bottom of seat ring bores in a lathe-type action with a single point carbide cutter. The RDS is aligned in centerline with the valve guide by means of a pilot which is locked in the valve guide. An universal steady stabilizes the RDS against lateral displacement. Pilots and steady furnished with Hunger valve seat refacing tool also suit for the corresponding RDS tool. The built in feed gear mechanism for automatic longitudinal and cross feed of the single point cutter eliminates the need for multiple cutter sets and other accessories. An adjustable stop for the tool slide permits quick selection of the proper sized bore diameter.

Application The K2000 cylinder head stand is designed to support automotive and motorcycle cylinder heads on a workbench so that service or repair jobs, such as valve work or head cleaning and assembly can be easily performed. Features The cylinder head clamped onto the K2000 can be rotated by 360° and may be fixed at any desired angular position. Therefore, assembly and disassembly work can be done with the cylinder head in the most appropriate position. An universal valve spring compressing lever is supplied to remove and install the valve springs.

Application The BDW is designed to reface the seating provided in the engine block for receiving the flange of the cylinder liner. Capacity Refacing diameter range 90-180mm Features Centering in the cylinder bore is automatically effected by simply turning the centering spindle. The studs at the engine block are used for rigidly clamping the BDW to the engine block. The seating is refaced to the preset depth by the simultaneous application of both a rotary and a transverse feed motion to the single point cutting tool. While the single point carbide cutting is rotated around the seating, a feed gear mechanism ensures a transverse feed motion. An adjustable depht stop makes sure that all seatings are cut to the same depth.

Application With the PVM1 assembly set, worn valve guides can be quickly and easily removed from the cylinder head and new valve guides inserted into the cylinder head. The assembly set is particularly suitable for motorcycle, car and commercial vehicle workshops. Features The air hammer can also be used to drive valve seat inserts out of the cylinder head. For this purpose a Hunger valve seat turning device is used to turn a groove into the valve seat ring. The seat ring is driven out of the cylinder head by means of a clamping head whose expandable clamping elements engage in the groove. Handling Insert the appropriate drift pin into the pneumatic hammer and insert the drift pin into the valve guide. Switch on the compressed air supply with the control lever provided on the pistol grip of the air hammer. The valve guide is driven out of or into the cylinder head by the rapid impact sequence. A soft protective ring placed on the drift pin protects the valve guide from damage.

1.Standard Equipment DP1 Valve Leak Detector including a set of seven adapter plates, a flexible extension hose and a sturdy storage case. 2. Working Principle Applying an air pressure of about 6 bar to the DP1 Valve Leak Detector results in a max. vacuum of about 850 mbar which is applied via an adapter plate to the inlet or exhaust port of the cylinder head to check the respective valve for leakage. The vacuum gauge at the DP 1 indicates the tightness of the valve.

Right-hand cutting reamer with expanding blades. Due to the unique Hunger relief grinding operation the blades have a progressively increasing clearance angle giving a soft cutting action. Starting with size D 12 the adjusting nut is marked with an annular scale. One graduation of the scale corresponds to a change of the reamer diameter by 0,01 mm. The reamers are available with standard blades made of high quality special steel to ensure superior cutting performance. The reamers are also available with hard chromium coated blades. The hard chromium coating has superior hardness in combination with a low friction coefficient. Thus reamers of the "hard chromium" series are particularly suitable for reaming abrasive materials and materials with a tendency to adhere to and to build-up the cutting edge.
