Ampscot™ jackshafts are available with either a 21/4-inch or 2 7/8-inch single shaft extension manufactured from 4140 annealed steel. This system permits the operator to release two bolts on the jackshaft and have the head swivel back and forth. Ampscot jackshaft assemblies come complete with a universal-type mounting system. Both sets of belts can then be adjusted by moving the prime mover. The shaft is mounted on roller bearings and is housed and sealed to prevent contamination. The jackshaft is designed to carry sheave sizes up to 24-inch diameter allowing up to a 4 to 1 reduction if necessary. When both sets of belts are at the desired tension all you have to do is retighten the swivel bolts to maintain belt tension. Another feature of this assembly is our swivel-style.

This system makes it very simple to service the bearing without removing the walking beam. which are a Equalizer Bearing for Pumping Units 228 & Larger complete unit. Removal of two bolts allows easy removal of the equalizer bearing and pin. the double tapered roller bearing is incorporated in a housing that is bolted onto the walking beam. This design also utilizes a minimum Equalizer Assembly for Pumping Units 228 & Larger number of parts. This design greatly simplifies maintenance procedures by providing easy access to the assembly for parts replacement or servicing. When the two wedge bolts are removed the pitman assemblies can be lifted off of the equalizer bearing.

This is a simple.PUMPING UNITS 114 BRAKE ASSEMBLY Ampscot™ 114 and 160 pumping units are equipped with a Bendix 3x9-inch internal expanding brake assembly. which allows for quick and uniform belt tensioning. When both sets of belts are at the desired tension all you have to do is retighten the swivel bolts to maintain belt tension. Ampscot™ jackshafts are available with either a 21/4-inch or 2 7/8-inch single shaft extension manufactured from 4140 annealed steel. Both sets of belts can then be adjusted by moving the prime mover. This system permits the operator to release two bolts on the jackshaft and have the head swivel back and forth. Another feature of this assembly is our swivel-style. The shaft is mounted on roller bearings and is housed and sealed to prevent contamination. which allow an operator to retrofit them onto any type of pumping unit or directly onto the concrete base. Ampscot jackshaft assemblies come complete with a universal-type mounting system. The jackshaft is designed to carry sheave sizes up to 24-inch diameter allowing up to a 4 to 1 reduction if necessary.COMPONENTS PARTS IDENTIFICATION JACKSHAFT ASSEMBLY The purpose of a jackshaft assembly is to allow the operator to slow down a pumping unit below its capabilities with standard sheaves and belts.
