 |
|
When I talked to Van's, I told Scott Risan that my engine was an
experimental Lycoming built by BPE and Scott said that he knew "that
those guys in OKLA cast there own sumps". It didn't seem to be an issue
with him. Scott was EXTREMELY helpful, offered to pay the shipping. (I
agreed to split it with him). I didn't think that grinding the rear of
the fins would have given me the clearance I wanted/needed.With the fins
ground, I _might_ have been able to get it hung and to get the upper
mount/bolts in, but the clearance with the cross member would have been
too tight to provide peace of mind for the engine settling when the
mounts compress over time.

not hurt it to grind off some for clearance.
Vans won’t talk to us BPA users because we are “Hot Roders”. They told
me I was on my own on that. Wonderful Aircraft and for the most part a
good company, but sometimes they just drive you nuts.

Gary, just a question based on A & P school experience. Why would
anyone grind a fin on an engine rather than have the errant clearance
corrected by a properly modified engine mount?
Does anyone know if VANS is yet properly modifying the mount or will
Deems' be the first sole with a third generation modification? I am
waiting with anticipation to hear that his mount was a first
generation "non modified" variety.
On a second note, How does BPA feel about kit builders grinding their
engine components? This might just be an important point on Safety
being passed over by the reading audience.

I needed to grind off some of the fins on the bottom ob my cold air
induction sump to give the clearance I was comfortable with.

Just to let everyone know, I talked to the guy at Van's that welds the
engine mounts. They are made in house. I asked about the bar hitting on
Tim's and he said that the bar was an after thought for some added
strength. He said it could have gone anywhere between the two down
tubes. On the 220RV it cleared just fine and on my engine that I bought
used and had rebuilt if fit fine. He did say that they had moved the
bar down and shouldn't be a problem any more if you have a pan like
Tim's. Well it looks like they may have to move it again. Randy 40006
