I have the per-the-plans VIP mounts 50901-73 and 50900-71. Prints call out alternates J-7763-10 as the harder durometer piece and J-9612-8 as the softer larger piece
Are the subject Lord J9613-40 and 49 the same diameter and dimensions?
The VIP are probably circa 2003 and 700 hours, I swapped bottoms to tops 2 seasons ago. They did not sag much, the extra washer realigned the spinner to cowl and that has not changed- but, it's time for the Lords.
I asked Ryan at Herber for a quote, assuming they are the right diameter for the type 1 O320-E2D. It's a 9:1 engine and I played all the clocking with the FP 70CM prop.
Will I keep the extra washers with new Lords or do they not sag after 50 hours?
Thanks! ETA- Ryan says -40s are $148 ea @Herber today.
