Rear Transmission Mounts

[lancair90]

Has anyone had occasion to change the rear mounts on a 1949 Dodge with the car together?

I can't get the transmission high enough to get the rear mounts out of the crossmember.

I would appreciate any help and advice.

I was able to get mine on the 49 Plymouth..same setup..it is not without a fight I will assure you...

[lancair90]

Yes, I can see it would hard to do. The problem seems to be that the big washer with the spacer attached to it won't come up far enough to clear the crossmember before it hits transmission or the floorpan.

man..we could have traded labor.me with my lift and some time to install the mounts..your back and sweat digging trenches...

[P-12 Tommy]

If I could get there quickly I'd take you up on that.

So exchange rate is 10 feet of trench per motor mount??? Or is it ton of dirt?

[Plymouthy Adams]

10 feet of trench per mount..he would have to have 5 mounts changed at that rate..however the trench is is done, lines are buried, yard is back to landscaped and seeded with winter rye..

well.....I guess we ain't adoin' that.

Has anybody ever popped the rivets off the crossmember and made it a bolt-in? I would sure make it easier to change mounts.

The body has dropped down over the years to make it hard to get the bell housing raised enough to be able to remove the 1 piece welded large washer and tube assembly thats inserted into the motor mount. I use a Hydraulic jack( porta power) to push the trans and bell housing up that little extra bit so I can remove/install the new mounts in these situations.

Place car securely on ramps, stands hoist, get her up, safely.

Loosen front engine mounts

place floor jack under trans with wooden piece between jack and trans

unbolt rear motor mounts, and remove bolts

lift trans with jack, just enough to be able to slip motor mounts out

install new mounts, and bolt into place (use new fresh grade 8 bolts,nut,washer)

retighten front engine mount

re-adjust shifter linkage if necessary

Call the Boo Bird Flock and let em know you did the job........LOL

Thanks Fred. I had the tranny jacked up and it was hitting the floorboard. Still no room. I just talked to Tim and he give me another alternative.

Thanks to you Bob for that little bit of info.

I'm working on replacing the rear mounts but I'm not able to replace the new ones since I don't have enough space to slide the new mounts. Can someone please assist? Thank you.

Check the body mounts. If they have collapsed, you might have to loosen some body to frame bolts and lift the body up some to gain enough clearance.

I've thought of doing this too.  Would also make it a lot easier to pull and install the engine and trans as a unit.  I was thinking of using some Riv- Nuts and welding them to the frame.  

 

Anyone done this.

[DonaldSmith]

I gave up trying to replace my motor mounts this Fall.  I jacked the transmission up against the floor, but it wasn't high enough.  

 

I thought about drilling out the rivets on the crossmember, maybe next Spring.  I would have to cut out the weld along the bottom at the frame.  Then I noticed in photos the master cylinder mount, welded to the crossmember.  That would complicate things.  I would have to support the master cylinder.  Well, I'll have all Winter to think about it.

Why not just do it right and pull the engine / bell housing forward off the mounts?

You will only have to do it once in your life time.

I was able to do it on my 1950 Dodge Meadowbrook. Took some doing, maybe the disconnection of the clutch lever and the shift rods. And you have to raise the trans pretty high, but it's possible.

 

My issue and I'm curious about the forum's opinions, is that the new mounts I got were smaller than the originals and quite a bit stiffer, so once installed, a lot of engine vibration and noise was noticed in the interior, so I reinstalled the original, oil soaked one and stacked a couple of large washers to regain some height lost to the rubber settling on the originals. Are there good, original design rear trans mounts available?

There is an upper and a lower. Did you get the lower only?

Take out the floor panel and Jack up the oil pan.

[Dodgeb4ya]

Removable floor pans on 1949 cars is only on the drivers side of the car and small unlike1946-1st series 49 cars. It's removal won't help much when raising the bell housing up.
