Cylinder Sleeve Puller

Cylinder Sleeve Puller ENGINES Engines 33-5-38 Georg Hertz-Kleptow of Dapp, Alberta couldn't justify the cost of a commercial hydraulic-cylinder sleeve puller, so he made his own. With only about a $360 investment and 12 hrs. of his time, Hertz-Kleptow built a unit that serves his needs well. "Hydraulic sleeve pullers are very expensive and it's not something you use every day. You could spend $5,000 for a comparable unit," he says. "I'm really happy with mine. It's a 30-ton puller with a 5-in. inside dia. cylinder." The specialty tool pulls engine sleeves and also presses new ones in. It's something that Hertz-Kleptow needed in his shop, where he works for neighboring farmers and also himself. Hertz-Kleptow saved money by being able to use an existing hydraulic pump in his shop û one that he normally uses on his hydraulic press. Hertz-Kleptow salvaged two hydraulic cylinder rods from an old air seeder and used them as the sleeve puller's frame. To power his unit, he already had a hydraulic cylinder "laying around". He spent about $80 on hydraulic fittings, hoses, 2 pressure gauges and other miscellaneous materials. Because various engines have different sleeve sizes, the puller also needed several adapter plates. Hertz-Kleptow had a local machine shop make up 3 sizes of adapter plates for about $40 each. The adapter sits under the sleeve to catch the bottom edge of the liner, and a threaded rod connecting the hydraulic cylinder to the adapter plate pulls the liner up through the boring. "I also use the sleeve puller for pulling large tractor tires off axles as well as pulling king pins out of the front axles of FWA tractors to remove final drive pivot housings," Hertz-Kleptow says. "You only need a welder, a torch and a drill press to build it." Contact: FARM SHOW Followup, Georg Hertz-Kleptow, P. O.
