TCRD=Transfer Case Reduction Drive


   We finally managed to disassemble the np241J, 52853-400AC, 09-06-07-J1, 2.72 transfer case which at weigh-in time weighed 80 pounds and when reduced to usable parts weighed 25# less the case, prop hub, and outer gear reduction ring.

   Primary initial hope for the all up weight is 40# which appears to be within striking distance.

   At the present time we will use the automatic transmission bell housing as mounted on an Rx8 engine which benefits from a very light weight of magnesium, a standard starter which mounts such as the advantage of shifting the C/G positively in both a pusher or tractor configuration, and reduces liability when the TCRD Kit is sold in parts and personally certified by the builder as airworthy.

   We will use a 4:1 gear set sold separately, but have been unable to confirm that the driveshaft splines will fit one of the 4:1 input gear with 5/6 pinion gears.

   If anyone has knowledge, or where to get the information of a combination please give us a shout.

Please excuse me, as there has been talk about the TCRD in the past year, we have access to cheap 3.10 to 1 gear sets,
from GM and Ford, so I am not  following here !. Where is the 4 to 1 gear set in this case? I think most of these parts
are acquired as is, and without other parts used to make a complete PSRU, assembled, where does liability come into play ?
