Lycoming SB 632 7/17/2017
I just saw this on a facebook post. Going to read the entire SB then try to track down serial numbers for my rods that were installed a couple of years ago during my OH to see if I have to do this. This could be a huge expense for some Lycoming owners.
EDIT: Looks like my engine won't be affected as my rods were shipped in 2014, before the specified time period. http://www.lycoming.com/sites/defaul...0Removal_0.pdf |
Yup, our engine is on there. In fact, I'd say if you bought a Lyc in the past year, you're on there.

Yeesshhh.... this one might get ugly.

Lycoming must realize they really stepped in something here - curious to hear the backstory on this one. At least its a relatively small time window for production. My engine is not on the applicable list, I dodged this bullet. |
Big bummer. I'm always amazed when something like this comes up as the engines really haven't changed since the 50's.
Have they ever been perfect or does one SB eventually just create another down the road after material and or procedures change? I'm guessing it is always work in progress after looking at the 74 pages of Service Bulletins Letters and Instructions. Wow, tough business... |
Can you replace the con-rods and bearings without splitting the case? Doesn't look practical to me but I've never opened an engine either. This looks like a pretty invasive fix to a nearly new engine.

I didn't see a date for the engine/parts shipped but checked my S/N and luckily I am not affected
|
Got my engine through Van's at SnF 2016. Still in box.
And it's on the SB list. |
