Discussion:
Piston Ring Groove Wall broken.

This is in reference to Daewoo Forklift G20S-3 using a Hercules 2.7l engine. We have just dismantled an engine of this model as it was having heavy compression leakage. When we removed all the pistons from the bore we found that in Piston # 1 + 3 the wall between piston ring 2 & 3 had broken and come away from the piston. Does anyone have any idea as to what could be the reason for this failure. The engine was being operated on LPG.

Ive dealt with this as well on the herc engine. My best guess was preignition, detonation, or overheat.

We have looked into that aspect and found that no starting aid wa used. Could it do with something on the LPG composition

My guess would be someone has used a starting aid such as ether on this engine

Take time to do the job right the first time, or you will have to make time to do the job over
