Thrust Plate

Well that's a shame! MAM changed another item that was 100% perfect the way
it was, to make it fit something else at the expense of "Mickey Mouse'ng"
the original installation for our Rebels! Glad Darryl had sent Howard a
spare to replace the new one we had just put on his Rebel prior to Oshkosh
last year, that had to have a crack stop drilled up near the nose. Cracked
one is still on and not getting any worse, but I hope the replacement that
Darryl sent him is the older version or we will be farting around to install
it and need to buy longer bolts!
That set of prop bolts from Sensenich is worth $250+Cdn (well maybe not
worth, but that's what they cost!). If MAM knows that you have ordered a
spinner and a prop through them from Sensenich, they should make sure that
Sensenich ships a bolt set for an S11 assembly and not an S8, For those that
don't now the S= spacer (in the prop assembly 74DM7S8-0-56) and the number
is 1/4's of an inch. ie: 8=2" spacer and 11=2 3/4" that would equal the 2"
spacer + the 1/2" Mickey Mouse spacer + the 1/4" of the E-26.
Bruce, when you put the prop bolts in, the proper bolts with the 1" thread
length will protrude through the back of the bushings a few threads if the
correct length. You can use normal AN7H-** bolts (that's all the newer style
prop bolts are with just the double length thread instead), but it is a fine
line between bottoming the threads and having enough into the bushings to be
safe. You should be able to put your finger across back of the bolt bushing
on the prop flange and the pad area of your finger should be able to touch
the end of the bolt, otherwise they aren't in deep enough! I always hand
thread the bolts into the flange without a prop on and bottom them out
lightly. Then I take a feel behind the flange to see where they are in the
bushings. Remember this location and make sure you don't go this deep with
the bolts when everything is torqued in place.

beWayne,
The front bulkhead bolts on with the prop bolts. I do have the metal
Sensenich for an 0320 from MAM that measures 4". My front bulkhead HAD to
bothspaced exactly a half inch from the prop to meet up with the spinner.
Is the 0360 prop 4 1/2" thick? Maybe MAM is using this spinner kit for
boltsinstallations now, to consolidate inventory. I recollect Grant mentioning
that I wouldn't have needed the spacers with an 0360. At any rate, the
engagementSensenich sent out with the prop made no allowance for any spacing of a
bulkhead, or thrust plate. I believe the bolts have to have thread
flange.at least the diameter of the bolt. In this case 7/16" into the prop
