MECHANICAL DAMAGE 
IN CRANKCASE

Check plungers, connecting rods, bearings and crankshaft for damage.

Repair or replace if needed

 Noises caused by these problems are unique.  There is nothing like the sound of 2 pieces of metal coming together.  

Generally, if it's a knock in the crankcase, the problem is with the connecting rods or crankshaft.  Usually, if it's a grinding or scrapping sound the problem is a bearing that the crankcase turns on. Either way the noises are distinctive and means there is a serious problem with the pump.  

Crankcase repairs can be very expensive.  If it's a bad crankshaft bearing or connecting rod, the crankshaft may also need replacing.  You may find a dealer/repair shop with used parts.  If not, and you have to use new parts,  you will be better off with a new pump.  Some super duty, expensive pumps are worthwhile to fix but smaller everyday pumps are not worth it if you need a crankshaft and bearings. 

The best way to prevent crankcase problems is to make sure you change oil according to manufacturer schedule and specifications and do not overheat the pump.

SOME OF THESE OPERATIONS CAN BE EXTREMELY DANGEROUS.  IF YOU DO NOT HAVE SUFFICIENT TRAINING IN THESE PROCEDURES, WE RECOMMEND YOU SEEK ASSISTANCE FROM A
