Engine mountings replacement

[Mrbrylcreem]

Hello again. I would like to know if anyone has any tips on placing the engine mounts on my 47 Dodge truck. Especially the front one. Plus what should I be looking out for when lifting the engine. As not to do any damage.

Really just use your brain, most everything on these trucks is very rugged. Worst part is lifting points. Some people put a chain under 2 head bolts in opposite corners, if you are lucky you may have found a factory engine lifting hook. Other than that its all about taking your time

Good luck

Yup chain between two headbolts or I've seen a cable setup that bolts under them too. You shouldn't need to lift it very far to replace the mounts. My car and truck both got new ones when I put the engines back in but I did them in my dakota lifting the engine from underneath with blocks of wood and a floor jack. Just don't dent the oil pan.

I was thinking a jack under the oil pan, with a good wood block to spread the load, would work fine to raise the engine enough to remove the front mount. Just go easy and only enough to be able to get the mount out. Once the front is done move the jack under the transmission to lift the rear for rear mount replacement.

Yes sir that works just fine.

Many thanks for the tips. I would like to know if I need to pull the radiator out. Or could I work around it in replacing the front mount.

your really shouldn't have to, but I'd at least pull the fan just so the radiator doesn't get beat up.

I'm thinking that removal of the fan and pulley may be necessary to gain the needed room to access the upper mount.

This thread just got me wondering. When I pulled the motor out of my 52 it had no rubber isolators between the front engine mounts and frame crossmember. It was just hard mounted with two bolts to the crossmember. The motor was not the original to the truck it was from a plymouth car. Just wondering if someone could post a picture of the mounts and how they were installed. I'm just curious.

Thanks,

The front mount is supposed to be bolted solid to the cross member. The rubber isolator is between the top of the triangular mount and the engine's front cover plate.

Attached is a pic of the front mounting.

Thank you Merle and Mrb. I had no idea there was a rubber isolator there. Learn something new everyday....

I wonder, does replacing the mounts make much of a difference? Mine are all still intact, but just curious.

[JBNeal]

the rubber mounts dampen the inertia & vibration from the motor, which helps to keep the frame mounts intact and reduces the risk of crack propagation.  If they are rock hard, they aren't dampening as much as they are transmitting vibrations & inertia.  Also, the engine mounts help relieve any stress that may want to transmit from the frame whenever it flexes.  They are to protect the frame from the powertrain dynamics, and to protect the powertrain from the frame dynamics

I never really thought of the reason for the mounts being located where they are until I watched a great old training video that Bob posted recently (there were actually 3 old videos in that link)... http://p15-d24.com/topic/35490-for-your-viewing-pleasure/ . One of those videos showed an engine stability comparison between Dodge and Ford with the engine mount placement (see attached picture) in which one can easily see what the MOPAR Engineers were thinking when designing the engine mounts back then. It would stand to reason that a Dodge truck engine would have better stability than a Ford truck engine bearing this theory in mind.
