Merlne units have reverie-reduction gears. Cylinder block is welded of flame-cut eteel sections, stress-relieved and magnafluxed. Air receivers and duets from rotarytype aeavenging blower lorn an integral part of tha block, add to ha rigidity. Bear ing saddles, also an integral part of the block, are line bored. A bevel-gear-driven, flexible, vertical drive connect* upper crankshaft to lower. Part of upper shaft power drives scavenging blower. Crank shafts are higb-eirength alloy cast Iran, cored for lightness end with integral counterweight*. Thrust bearing la at drive end. Precision main bearings are aluminum alloy; forged-steel caps mortise into frame. Interchangeable cylinder liners have steel water jackets fitted around middle where they also support combustion forces. Cooling water flowa through fluted pesaaget. Scavenging air cools upper part of liners; water circulating in exhaust-manifold hous- ng cools lower pert. Inlet and exhaust ports are located around entire liner cir cumference.

A removable piston-pln insert supparu hollow full-floating pin. Piston-cooling oil flows through pas sages between Insert aod inner piston wall. Alloy connecting rode are drop-forged. When engine operates at part load, out put of positive-displacement aeavenging blower i* reduced by an air bypass valve. This minimises blower power requirements. Blower supplies air receivers on both sides of engine; scavenging is uniflow. Exhaust manifolds, one on each side, are watercooled end removable.

The two mem bers are separated by a spoeo filled with small ferro magnetic particles (stainless steel). When one member It energised, the particles polarise and bind together, binding the rotating members together with a proportional force.

' (Continued on page 162) 164 REAPER SERVICE SECTION This "Buffalo" Pump pffers a high degree of efficiency in pumping large volumes of clear water. Available in capacities for 10 to 10,000 gpm at up to 300 ft., these pumps are hydraulically balanced--water enter ing both sides of the impeller in equal volume and pressure. Bearings on each end of shaft mean extra long wear. Horizontally divided casing makes for extreme accessibility in inspection and servicing. Pull details in BULLETIN 955-P- CLOSE-COUPLED |Here is a ruggedly compact pump for those jclo$e-c|uarters" installations. Pump and motor ^;(U rigidly mounted together with impeller on gjfmotor shaft, which means permanent alignment. ^"Buffalo" builds these pumps in a variety of alJloys for specific liquids, with threaded or flanged -^inlets and outlets. Pump casing may be rotated, Aar removed for inspection--on Important maime* frtmee factor. WRITE for BULLETIN 975-B. .3 MULTI-STAGE Each extra stage adds pressure! That's why pumps like these "Buffalo'' Type "RR" (2 and 4-stage models) operate efficiently against high pressures ($00 psi or 1$00 ft. heads). These "Buffalo" Pumps have proven themselves very durable in boiler feed and other clear water installations. Bearing sup* port on both ends of the shaft--rugged, horizontally divided cosing--solid, rigid base--all contribute to easy maintenance and long life. For further details, write for Bulletin 980*B.
