How to Fix a Broken Motor Mount for About $1.00
Tech article by taipeichris and filed under EngineTech article by Chris (taipeichris)
For numerous reasons I broke motor mounts in the past, usually I’d find out when I’d hit a bump in the road and the motor jumps up enough to hit the hood. Not cool, right?
Parts and Supplies Needed:
| Quantity | Parts Description | Cost |
| 1 | carriage bolt | $0.30 |
| 1 | lock nut | $0.20 |
| 1 | rubber bump stop | $0.50 |
| 1 | washer | $0.05 |
Tools Required
| 1 | socket set |
| 1 | drill press |
| 1 | drill bits |
| 1 | floor jack |
| 1 | block of wood |
So here’s my fix.
Remove your broken motor mount.
Drill a hole through it, the size depends on your carriage bolt.
Insert a carriage bolt through it with the smooth side up.
Using a rubber bump stop for a dampener, I drilled a hole through the dampener and fastened it with a washer and lock nut.
Grind the head of the carriage bolt flat, just enough to allow clearance.
Reinstall you repaired motor mount and enjoy!

We are some cheap so and so’s. If you do that much work, why not install a new mount. Many of the new mounts already have the bolt thru the mount trick already done.

Years ago my Mustang ate motor mounts like a child eating candy. So after asking around an old timer mechanic I met told me this trick. I must have changed out 7 motor mounts before I did this mod and I’ve never had to replace it since. [I didn’t know new mounts are sold with the bolts already installed.]

Great tip – I’m breaking motor mounts even with the motor tightly chained down with a turnbuckle. I had one new mount last about 15 minutes – :X
