Connecting Rod Aligner A-650-2R Chinelatto - Ø1.18-5.67in

A connecting rod aligner is used to correct deformations and misalignments in engine connecting rods, ensuring they remain perfectly aligned and perpendicular to the crankshaft axis. The A-650-2R model works with connecting rods from 1.18" to 5.67" (Ø30 to 144mm), covering from small engines to large applications. This machine is essential for eliminating problems like excessive vibration, irregular bearing wear and engine power loss, restoring connecting rods to their original specifications.

The A-650-2R Chinelatto aligner works with connecting rods from 1.18" to 5.67" (Ø30 to Ø144mm) and maximum length of 15.75" (400mm) between centers. The equipment weighs 143 lb (65kg) or 196 lb (89kg) with accessories and occupies 19.7" x 13.8" x 61.4" (500 x 350 x 1,560mm) of space. It comes complete with 8 sets of tempered expanding blades and 3 blade-holder shafts to cover the entire diameter range. This capacity allows working from motorcycle and small car connecting rods to industrial and truck engines.

With the diameter range from 1.18" to 5.67" (Ø30 to 144mm), you can align connecting rods from practically all engines in the market: from 125cc motorcycles to heavy trucks. It includes compact, mid-size and large cars, flex fuel engines, light and heavy diesel, agricultural tractors and industrial machinery. The 15.75" (400mm) center-to-center length handles long connecting rods from V8 engines and industrial motors. The 8 blade sets cover this entire range without gaps, ensuring secure clamping at any size.

The manual aligner like the A-650-2R offers greater control and precision in the process, allowing gradual fine adjustments until achieving perfect alignment. The operator feels material resistance and controls applied force. The hydraulic version is faster but may apply excessive force and damage more delicate connecting rods. For machine shops doing varied work, manual is more versatile and safe, especially on aluminum connecting rods or special materials requiring extra care.

The process uses tempered expanding blades that fix into the connecting rod bore, expanding to make full contact with the internal wall. The connecting rod hangs between both holes (small end and big end) over the machine's ground surface. With squares and dial indicators, you measure misalignment and apply controlled pressure to correct twisting and warping. The blades distribute force evenly, preventing damage to the connecting rod material during correction.

The A-650-2R aligner is a robust machine that mainly needs regular cleaning and lubrication of moving parts. The tempered expanding blades are the item that wears most with use, but last years if well maintained. It's important to keep the ground surface clean and protected against rust, and periodically calibrate the dial indicators to maintain precision. The cast iron structure is very durable, with these machines commonly working for decades with basic maintenance.
