Description
Small shop assembly benches experience press ram binding when low-grade casting guide slots wear out of square. The Dake Arbor Press Ratchet Lever 3 Ton Model 1-1/2B gives mechanics controlled mechanical downforce for pressing wheel hub bearings, pressing broaches, and assembling bushings. It delivers 3 Ton pushing capacity through a heavy hand lever. Ratchet mechanism engagement requires deliberate operator lever return strokes.
The one-piece base and column casting uses high-density semi-steel to resist spreading forces across the throat under full working tonnage. A heat-treated alloy steel ratchet gear meshes with a ground rack cut directly into the square alloy ram. The hand-operated ratchet pawl utilizes hardened tool steel to eliminate tooth slip under high manual input loads.
Ratchet Lever Mechanical Leverage Assembly
The ratchet drive mechanism allows the operator to position the hand lever at the most comfortable ergonomic position for long-stroke broaching jobs. A heavy slotted table plate supports diverse workpiece diameters during shaft push-out tasks.
- 3 Ton mechanical leverage capacity presses gears, bushings, and universal joints with precision.
- Ratchet mechanism allows multiple strokes for continuous ram travel through deep broach cuts.
- Adjustable hand counterweight automatically returns the lever to top dead center when released.
- 1.5-inch square steel ram maintains linear alignment to prevent broach drift and tool breakage.
- Four-position slotted cast iron table plate indexes to support various shaft shoulder sizes.
- Large 17.5-inch throat height accommodates tall component assemblies and hydraulic cylinder shafts.
- Ram shims allow easy adjustment of wear plates to maintain zero side-to-side slop over decades.
Mechanical Stress Bench Telemetry
Applying 85 pounds of downward force on the ratchet lever produces 6000 pounds of linear pressing force at the ram end. The semi-steel frame throat deflects only 0.0025 inches at full 3 Ton mechanical stall. Friction across the square ram guideway raises head temperature by just 8°F above ambient during continuous 30-minute bearing assembly routines. Sound emissions during operation remain below 58 dBA.
Mechanical Limits Service Protocol
Bearing repair stations, electric motor rebuilders, and machine shop tool rooms benefit from the mechanical control of this ratchet press. Do not purchase this press for high-speed automated production stamping because manual cycling limits output speed to hand crank cadence. Never slide pipe extensions over the factory ratchet handle to multiply leverage because you will crack the semi-steel frame throat.
- Coat the alloy steel ram rack teeth with heavy open-gear lubricant every 40 hours of use.
- Adjust the ram friction shims every six months to eliminate lateral wobble during delicate shaft broaching.
- Keep the rotating slotted anvil plate free of metal chips to ensure workpieces sit perfectly perpendicular.
- Inspect the ratchet pawl engagement face monthly for rounding or chip damage to ensure operator safety.
