How many hours do you guys have on the DL 50 I have one with 9.5 hours and the ring rotates about .090 .100 I think its the ring or pin-32.01 oil since new and broke on 1.0 hours on the ground , any one checked for this problem
the ring on my DL can rotate about 2 mm either way. I found the pin is only about 1mm raised from the groove bottom and has sign of wear at the top. Obviously that is a short pin and the material used is not very hard.
The pin on my DA has a length that is almost the depth of the groove and the ring has no chance to rotate.
I've ordered a new ring from Frank Bowman because of low compression felt. The engine has about 5 gallons fuel through it.
