this weekend im considering welding up my motormounts so that they are solid,ive busted them a few times ,it is a1994 f150,is there any reason i should not do this??

Do it! Broke mine twice a year also. But why not just weld up one side, This will still take some of the vibration out. I was going to do just the drivers side.

ya i think ill try it i was not totally sure if there were any reason not too do it

why not find some good poly mounts? id never run solid mounts unless it was just a 1/4 mile vehicle, its probably gonna have some nasty vibrations

where do u think i could pick up some poly mounts cris?

though of chaining the motor? we have to do it for the race truck, just run a length of chain from the block and to the frame. i will stretch enough but not wreck nuttin. and allow for vibration dampening.

I welded up my drivers side first, there was no difference in vibration.
then I welded up the pass side and there was a little vibration.
I like having the drivers side welded, now with new pass and tranny mounts it works great.
just make sure it's angled correctly before you weld it up and get good penetration.

so are u saying to weld it up while in the truck ,or weld it up and then install it

just put a torque strap on the drivers side of the motor to the frame. use a hevy duty piece of chain and good grade 8 bolts or a thick piece of metal

I wouldnt run poly mounts on the engine
poly doesnt like heat at all, low melting temp.
anywhere that doesnt see heat is a great place for poly
I have 10 year old poly trans mounts in my chevy

soo i guess ill just weld the drivers side then and leave the rest

I like the torque strap but the old fords have that built in back at the transfer case

but hes got a 1994 if you welded the motor mount I would be worried bout it cracking around the weld cause the weld will be a harder metal then the rest of it.

05-19-2007, 10:54 PM
u think it will crack around the weld??

05-19-2007, 11:24 PM
u think it will crack around the weld??

not if you use thick enough material...i'd use 3/16 plate or even 3/8 if your really worried about it and just bevel the edges of all the plates before welding to get maximum penetration

hope it works out[cheers]

if your other 2 mounts are in good condition then just mark the one you are going to weld before you remove it for welding. there is some adjustment in the mounting bolts but not much before it will begin to rotate off angle and cause your other mounts to wear out quicker.

cut out any rubber on the mount (i used a wire wheel), then weld it up with nice thick welds make sure you have heat marks on the other side of the metal or you won't have a good enough penitration and the weld will crack off of the material from the engine vibration. (do a practice weld on some metal of the same thickness) After welding allow it to cool about 5 min before you douse it.

I'd fab a mount for the transfer case , like the older fords had.

ok thanx for the pointers working on it now

i went solid mounts in my b-2 2x4box 1/4"thick on both motor mounts i dont notice any vibration in the truck but can feel a little bit through the frame and use nylocks or lock tight on the bolts too stop any loosening[cheers]

ok thnx
