Gunsmoke Posted May 6, 2015 Share Posted May 6, 2015 Bought a Deluxe CD8 Engine recently and I notice it has a heavy steel "over the pan" piece at rear of oil pan, looks like it might be a mounting bracket/support of some sort, fastened to block with the pan bolts. I don't see a similar part on my earlier CD8 Series1 block/pan. I know a crossmember runs side to side under the engine in this area and wondered if anyone knows whether the Deluxe Series used the cross member as an additional support for the engine, perhaps to reduce vibration? On the early car they used 4 point mounts, 2 at front and 2 at rear via bell housing. the Deluxe engine raised the horsepower 33% or so, and so I thought an additional center bracket might reduce torgue winding. Anyone know? Link to comment Share on other sites More sharing options...
Gunsmoke Posted May 6, 2015 Author Share Posted May 6, 2015 Here are photos of the mentioned "reinforcing/protection/mounting plate on underside of '31 Chrysler Deluxe CD8 engine. Link to comment Share on other sites More sharing options...
Gunsmoke Posted May 7, 2015 Author Share Posted May 7, 2015 No one has given their suggestion for this "add-on, so here's my thought. These engines are a challenge to mount on an engine stand due to the sheer weight cantilevered from one end and the load that places on the "ears" of the block where bell mounts. So a jack stand at front of engine is advisable. However, if one has the pan off (to work on internals), then by putting a part like this "add-on" after oil pan is removed, one has a support for a jack stand at this end. So in essence this is not a car part, but rather a servicing tool, which has been left in place. That might explain why this "add-on" is not listed in Chrysler Master Parts list. Any old mechanics out there have a view? I don't see any evidence it could be used for much else. I considered it may be intended to go on other end of pan to protect pan from rocks etc, but the lowest part of the pan goes 2-3" lower than this plate. So......?

keiser31 Posted May 7, 2015 Share Posted May 7, 2015 I for one have never seen that piece on any Chrysler product. Link to comment Share on other sites More sharing options...
Gunsmoke Posted May 7, 2015 Author Share Posted May 7, 2015 Mystery solved. A member kindly sent me this photo of his Deluxe CD8 setup, the piece is part of the rear engine suppport sandwich shown here. Not sure if the rubber was vulcanised to one of the steel pieces or held in place by screws thru lower plate as shown here. The crossmember shown is missing from my car's chassis (when a foreign engine was installed in 1952), so I guess I'll have to get one fabricated unless one of you has a spare.
