RE: [Chrysler300] 64 tailpipe brackets



Decent pictures of the J-K ram engine viewed from the left front and showing the LH manifold support bracket may be found in the 1963 & 1964 J-K Service Manual Supplements

 

The pictures are found in Group 9-Engine for both years.  1963: Page 8; 1964: Page 11.  The drawings clearly show the LH bracket supporting the bottom of the humongous CI exhaust manifold.  http://www.jholst.net/64-supplement/engine.pdf    The support bracket in question is the rather triangular horizontal flat plate below and behind the alternator and straight back from the fuel pump.  The support is bolted to the bottom of the block and the bottom of the manifold.  The picture also shows the thin section around the four bolt holes in the outlet flange.  Over-torqueing bolts connecting this flange to the exhaust pipe inlet flange can damage an ear or two on the cast-iron outlet flange.  Correct alignment appears to require precise alignment of these two flanges as there is only a flat gasket between the flanges.  Might have to rosebud the exhaust pipe to relax it into proper alignment.

 

Adding a support hanger at the muffler inlet might cause more problems than it solves by making the system more rigid.  The only flexibility in the steel portion of the system is the pipes themselves plus a little at the muffler inlet and outlet.  The two tail pipe supports are designed to isolate exhaust system vibrations and heat from the floor pan and frame while also dealing with the oscillations of the ram engine and expansion-contraction.  Getting all this to line up, along with the clamped tie over between the two exhaust pipes is where the amateurs and the pros at the muffler shop are identified.

IIRC either the 63 or 64, maybe both, FSM, somewhere in there is a picture of a Ram car on a hoist.

photo is of the underside and shows a ram car w/4 speed transmission.

You can plainly se that it is indeed a std trans car w/rams

Don’t recall if the support plates are  visible or not

Steve:

 

Go online to:  <http://www.jholst.net/64-parts-manual/engine-8.pdf> http://www.jholst.net/64-parts-manual/engine-8.pdf  Scroll down to Page 9-28 For the picture.  While not detailed, the brackets are bolted to the bottom of the block using two extra-long cap screws with spacers or washers under the heads of the capscrews to space out past the rolled-up edge of the steel pan.   That rolled-up/stamped -up edge may properly be referred to as the flange portion of the oil pan.  Then one bolt through the outer end of the bracket into the base of the exhaust manifold.  Spacers or washers would be used to assure a slight upward pressure of the bracket when everything is cold and bolted up.  Same on both sides.

 

Then, scroll down to Page 9-45 to see the brackets and spacers described and their part numbers. Items 9-48-77 and 9-48-86.  The brackets help support the front end of the exhaust system so that all the weight and dynamic loading does not hang on the manifold-to-block studs and flanges.

 

The rest of the exhaust section may be viewed at:   <http://www.jholst.net/64-parts-manual/exhaust.pdf> http://www.jholst.net/64-parts-manual/exhaust.pdf   Scroll down to Page 9-25 to view the 300K ram exhaust system from the exhaust manifold back.    Scroll down further to view the descriptions and part numbers for all components.

 

My friend John Holst’s most excellent website provides letter-car owners with Service Manuals and Parts Catalogs online at:  <http://www.jholst.net/> http://www.jholst.net/  

Let your fingers do the clicking, beginning with Chrysler 300 resources.  Manuals, catalogs, paint data and many other items of interest and importance will be found there.  The site is open to the public so your mechanic or other MoPar owner of the letter-car era may address the site and possibly find information on service and parts.  Now, finding those parts is the challenge, but if you have a picture and a part number, you are ahead of the game.   Thanks to John for creating and populating his own personal website.

Rich, Dave's &  All

Can someone send me a link or a copy of the Parts Book pages referenced for this bracket, Please. From the description, from the "Oil pan bolts" it sounds like it uses the "flange bolts" holding the exhaust pipe to the manifold, a picture is well worth a thousand words. All assistance is GREATLY Appreciated. Thanks in advance.

Thanks for your post.  I stand corrected.  Good point about the brackets that support the exhaust manifolds on the J’s & K’s.  Properly installed, they take some of the stress from the connections to the block.  In the 1964 Parts catalog:  Page 9-25 (Picture) and 9-45 (Description) for Items 9-48-77 and 9-48-86—Brackets and spacers.  If spacers are lost, flat washers should work just fine.

Regarding the J-K header supports.

There are 2 support plates mounted to 2 of the oil pan bolts on either side.

Longer bolts and flat washers needed to clear the flange on the oil pan.

They extend out and upwards somewhat and have 2 slight bends in each to compensate for the higher location of the mounting boss in/on the lower/main header pipe.

Pictured on page 9-8 of the ’63 master parts book part type code 9-48-77 part #2202-426, 2 required

Ironic the last 3 digits, huh, “426”

The 1964 Parts and Service manuals don’t seem to show any supports for the exhaust system other than at the muffler’s outlets and at the end of the tailpipe. Apparently, the supports at the rear of the mufflers are attached to brackets fastened to the bottom of the floor pan. If additional supports are common, are there any details on best practice and location? Supports similar to those at the rear of the mufflers could be added to reinforce and support the joints at the muffler inlets. Provision for thermal growth and engine oscillations and vibrations would be required. 

1959-1962 ram-engine exhaust and header pipes had varying degrees of support between the exhaust manifolds and the muffler inlets. It would appear that Chrysler engineers felt that the big cast-iron exhaust headers on the J & K engines would adequately support the front end of the exhaust system. A glance at the ’70 hemi exhaust system shows the first support is also at the mufflers’ outlets.

That said, I’m having to deal with a ram-K exhaust header with one of the four bolt holes torn out. There was not that much “meat” around the bolt holes. No telling how it was damaged but it looks like an installation or removal error.

Dave, 300 List

The long exhaust manifolds for the Short long ram, require support to hold up the exhaust pipe. If installing the pipe without proper support, the four bolt flange at the connection can break, from what I've heard somewhat easily. Can anyone send a picture of these supports for the exhaust / tailpipe "Installed", and possibly a dimensioned sketch, with mounting points. Any assistance is Greatly appreciated! I think this question fits in this "64 Tailpipe brackets" string, Thanks again!

Thanks for all the support on the K tail pipe hangers.

I found them as B body, the rubber straps need to measure up to your pipe.

And this is the last I'll say about them.

Thanks again,
