Inspection of the piston compressor revealed that both the clearance at the inner and outer end stops had decreased????
Thread Content
For piston compressors, have you ever noticed a reduction in the clearance at both the inner and outer end stops? There are probably several reasons for this
The actual procedure involves measuring the upper and lower clearances; this end-stop clearance includes the clearance of the crankshaft bearings as well as the clearance between the connecting rod and the small bearings of the intermediate shaft. Practical applications complicate the situation, making it unsuitable. These are the few things you want to ask, right?
Decrease both inside and outside? If the piston body remains unchanged, it is likely that too much of the cylinder head was inserted during installation; in such a case, consider adding shims to the cylinder head and then adjusting the crosshead connection.
What was said on the third floor makes some sense; the reduction on the outside side might be due to thinner gaskets, but I don’t understand why the stopping point on the inside side has decreased

Add shims behind the cylinder head for adjustment; check the tightness of the piston nut. Wear on the connecting rod bearing should cause abnormal noises
