Motor Mounts Constantly Breaking

[440sportfury]

Hello I asked for advice several weeks back on recommendation for motor mounts. I have a 68 sport Fury 440 convertible that the drivers side mount kept separating. I was purchasing over the counter Chinese made I assume mounts and they would be gone in 300 miles I don't do burnouts or abuse the car in any way besides maybe getting on it a bit on the hwy. I chose the Mity mounts on recommendations they were a little costly but they were easy to install fit perfectly and 750 miles still no worries of my engine coming up through the hood. Thank you for those that recommended these. I do not work for them or receive anything (because someone will say something) I highly recommend them so far. I am sure somebody will say theres better options which maybe there are but very happy with these and talked to others that use them with more hp and higher than 500 ft pounds and they been using them for many miles and race there cars and have had no issues.They appear to be a decent quality product and will give a lifetime warranty but you must send paperwork. Thanks Stay Safe Frank

Glad you found mounts that work for you. The ChiCom mounts are all crap because the rubber compound is inferior.

Thank you for the feedback. On the advice of several members, including @saforwardlook, I avoided the cheap mounts too but could not make up my mind between the Mity Mounts and the Schumacher Poly-Locs for Medina, my T-code (440-4) 1971 Monaco. So I got both, and decided to install the Schumachers first (thinking I'd keep the MM for Elsie, my 1973 Imperial). Well, after a few hundred miles of driving Medina with the Schumies, I concluded that they transmit too much vibration for my taste -- an opinion shared by @polara71 (who has the PL on one of his cars) and by @71Polara383 and @david hill (who have both driven Medina with the Schumachers).

As a result, this year I replaced them on Medina with the MM and sold the Schumies to @71Polara383 for one of his Polara builds. I'll post here if I am not happy with the MM, but I have no reason to expect less than complete satisfaction.

Any parts for our cars that are still available over the counter or online should be researched as to their country of origin. You are definitely better off spending a few extra bucks or looking a little harder for the part you need to get the good quality parts our cars deserve.

a torque strap or rod will keep the mount from going too far. and you will still have the comfort of the rubber mount.

Thank you Dave I was buying mounts from a fairly reputable old time shop and they were lasting 3-5 days of 15-20 mile nighttime rides to the beach at speeds no higher than 70 miles per hour. What junk but they were only 25 bucks. The owner couldn't believe I was telling him the truth. What junk Have a good day and thank you for your advice you have given me over the years of restoring my car. Best Regards Frank

Actually most of the junk motor mounts come from India.

These are rubber and they are vibration free. To tell you the truth they seem to be better than the originals when the motor was stock. Best Regards Frank

I have kept the old mounts and boxes for whatever strange reason One of the pair in fact is from India The rest good old China LOL Best Regards Frank

Wish you the best of luck . I will keep my fingers crossed for the both of us good luck Best Regards Frank

I put limiters in my standard mounts. So far so good - the comfort of a rubber mount and there's no way my motor's going to pull that stainless bolt and jamb nut apart...

It's not how fast you drive, but how hard you accelerate from a stop. That's when the torque reaction is the greatest as the engine's rotation will try to separate the lh mount.

As the rubber ages, it dries out and loses some of its flexibility. Continued "flexing" form throttle applications tends to wear it out. Then it will pull apart on heavy throttle at lower vehicle speeds. Just the nature of that particular design. Chevy had real issues with their OEM mounts in the later '60s, which generated a massive vehicle recall and their famous Motor Mount Retention Kit installation. Later mounts had a tab which hung over the bottom as its "fail safe" function. On the vehicle which had throttle linkages with rods, the throttle could hang when the motor moved enough from a failed lh mount. Not so bad with a throttle cable system, it seems.

ALSO check/replace the rear transmission mount too!

Just some thoughts,

Since Schumacher has no mounts in stock...
Just chain the sucker down..

 

[cbarge]

Seriously,
My next recommendation is a lot more involved but in the long run makes more sense.
Next time the motor has to come out altogether,swap in 1973 and newer spool type motor mounts. They hold up much better than the biscuit mounts.
This requires cutting out the old mounts and welding the spool type one and using the matching spool mounts that bolt to the engine.
No more blow-outs,and makes engine re & re much easier.
Hope this helps

1973 and newer spool type motor mounts

Did the engine mounts change in 1973? Mity Mounts lists the same part (BCE66-74) for fusies through 1973 (Fury) or 74 (Dodge, Chrysler).

My 73 Satellite wagon has spool mounts and yet I had to order mounts for a 75 yom.
Not all parts lookups are accurate.
Add insult to injury 1973 was a year of changes in the Mopar camp.

For C-bodies, the part number from the 1973 book is indeed different from the 1972 book. Compare pp. 9-12 and Illus. 9-13 of the 1973 Parts Book:

with pp. 9-13 and Illus 9-14 in the 1972 Parts Book:

Thanks @cbarge for alerting me to this issue, I case I ever need to replace engine mounts on my '73 NYB.

My 73 has the biscuit, or sandwich type mounts. I too had the same problem with the chicom mounts. That was one of the first parts I replaced on the car after purchase, and man it was a pain, only to be completely surprised two weeks later when the LH mount separated. I was able to get another brand at the local parts store, which was made in Korea, and holding strong 5 years later. Still have the chicom on the RH side. When I pull the motor, I will replace with the Mity Mounts...never heard of them before and thanks to all for the tip!

If you have photos of the Korean brand, that would be good for folks who don't want the MM -- or for whom they don't work.

Take each case inividually. Some are biscuit ,some are spool.
