Mi-T-M PUMP – CRANKSHAFT Part 46-0716

Description

Mi-T-M PUMP – CRANKSHAFT Part 46-0716

Restore the mechanical heart of your pump or air compressor with a factory-certified OEM Mi-T-M replacement crankshaft assembly. The crankshaft is the heavy-duty core of your equipment, responsible for converting the rotational energy of your engine or motor into the raw, reciprocating pumping power that builds air or water pressure. When a crankshaft becomes scored from contaminated oil, bent from extreme overloading, or suffers a journal failure, your machine is completely sidelined. Rebuilding with a genuine OEM Mi-T-M crankshaft assembly guarantees the exact stroke length, precise journal diameters, and critical factory balancing required to return your pump or compressor to its original performance ratings.

Key Features & Benefits

• Forged Industrial Construction: Manufactured from high-strength forged steel to withstand the brutal, continuous mechanical stress and intense heat generated by commercial pressure washing and air compression.
• Precision-Machined Journals: The bearing and connecting rod journals are machined and polished to a mirror-smooth finish, minimizing friction, reducing heat, and maximizing the lifespan of your internal pump components.
• Factory Calibration & Balance: Perfectly weighted and balanced to eliminate the destructive heavy vibrations that cause premature bearing failure, metal fatigue, and cracked crankcases.
• Exact OEM Stroke Length: Because the crankshaft dictates the travel of your plungers or pistons, using an exact OEM replacement ensures your machine perfectly maintains its factory-rated GPM (Gallons Per Minute) and PSI specifications.

Common Signs of Crankshaft Failure

Replacing a crankshaft is a major rebuild. You likely need this OEM assembly if you have experienced:

• Catastrophic Oil Loss: Running the pump dry almost instantly scores the crankshaft journals and welds the connecting rods to the shaft.
• Water in the Oil: Milky oil degrades lubrication, leading to deep friction grooves on the crankshaft.
• Severe Knocking or Locking: A seized or heavily knocking pump often points to a failed crankshaft journal or a broken throw.

Compatibility

Genuine Mi-T-M crankshaft assemblies are available for the specific high-pressure water pumps (including Mi-T-M, General Pump, and AR brands) and heavy-duty air compressor heads utilized across the entire Mi-T-M industrial equipment lineup.

Warning: Crankshafts are highly specific to the exact pump or compressor head model, not just the overall machine. You must locate the data plate directly on your pump or compressor and cross-reference that specific model number with your Mi-T-M parts diagram before ordering.

If your crankshaft failed due to lack of lubrication or contaminated oil, your connecting rods and main bearings are almost certainly damaged as well. Never install a brand-new OEM crankshaft into a pump with old, worn bearings or scored connecting rods. Always rebuild the entire bottom end simultaneously, and generously coat the new crankshaft journals with high-quality assembly lube during installation to prevent dry-start damage!
