Goetze History
Goetze is one of the longest established names in automotive, delivering technically advanced components that significantly lower oil consumption and reduce emissions.
DO's and DON'ts: Piston & Piston Rings
- Piston pins should not be hammered into pin hole
- Piston rings should not be mounted by hand, always use a good quality ring installing tool/expander
- While finally installing the piston & ring assembly in the cylinder, care should be taken that the ring gaps are not aligned and are at equal angles with respect to each other
- Make sure to sufficiently lubricate the piston/ring while inserting in bore, this is required for initial lubrication
- Use a good quality ring compressor while fitting the piston/ring in the cylinder
- The ‘top’ marking on the ring indicates that it should be installed with ‘top’ mark towards top of the piston
- In oil rings with springs, the spring joint should be exactly opposite to the end gap of the end gap
- A good quality circlip plier should be used for installation, also ensure proper fitment of the circlip in one groove and keep the open end downwards in position
- Do not check the tension of the rings by repeatedly pressing it by hand, it can easily disturb the alignment of the end gaps
PISTON RING ASSEMBLY ERRORS
Assembly errors can and will contribute to high base pressure and can cause oil to bypass the rings. This can create a build-up of abrasive carbon, which can lead to ring scuffing, a loss of ring control, and possible piston seizure.
PROBABLE CAUSES
- Piston ring end gap misalignment
- Expander end gap is same as oil ring end gap
When piston failure has occurred, it is extremely important to thoroughly inspect all of the engine components during the disassembly procedure. This thorough inspection will lead you to the possible cause or causes of the piston failure and will ensure that the same piston failure doesn’t occur once the engine is repaired and placed back into service by your customer.
