I updated the Insight pack removal and disassembly pages so that they would print correctly. Basically I just adjusted the picture size and text spacings. Printers should be set to landscape and .5″ margins on all 4 sides.

Honda calls this mount a rear engine mount. I call it a transmission mount. In any case, I had to replace it with a factory new part so that the clutch wouldn’t chatter so badly. It worked very well!! The clutch engagement is far smoother than it’s ever been. Ran about $97usd.

Since the urethane added to the mount was only cured for 40 hours when I test drove the Insight today, I was a bit nervous that it would not be cured enough to withstand the test drives. But it worked. It does not respond so harshly to having a chattering clutch with the motor mount repair/improvement that I made with the Loctite Urethane from Home Depot. I tested the worst case situation for the motor mount over by my mail box. The driveway there is a bit steep. I usually have to back out of it going up hill. Backing up this hill made the engine shake thunderously due to the worn out rear motor mount. But now it feels as though the clutch is still chattering, but the whole engine and chassis are not responding to the chattering any longer. I could back up the Insight at far lower rpm and still get a fairly smooth motion out of the car considering the clutch chatter. Now the test will be to see how long the urethane mod lasts. The cure time is 7 days. I’m hoping that setting it to cure under a 100w incandescent lap helped to shorten the cure time. In fact the lamp browned the white urethane just a little on the surface. The center bushing and the mount itself was quite hot after sitting over night under the 100w bulb. Those inefficient bulbs sure make for easy curing ovens. So I think this repair/mod of the rear motor mount was a worthy improvement for general reasons, but specifically for helping tame the clutch chattering so many of us have. I knew the mount was stiffer as I could not tilt the engine up and down with my hand while laying under the car. It was located far more firmly. I could not tell that any more vibration was added to the chassis by making this mount a little stiffer. The car still feels smooth and quiet as far as vibrations are concerned.

The car seems smooth on acceleration since I’ve cleaned out the egr plate. I’ll still swap out the egr valves to see if they produce any noticeable change in driving feel. I also put a bunch of missing screws back into the under chassis aerodynamic panels. They cost a bit from Honda.

I saw that there was some room for a screwdriver to pry the crankshaft dampener away from the engine to help check for end play. Pushing the crank back in will be tougher.

A few things I found out tonight working on the Insight.

There is not an inspection panel to check the crankshaft end play. The oil pan would have to come off. The oil pan is clear of any obstructions, but it has the oil filter and something else attached to it. Decisions, decisions.

Here is the rear motor mount from my MT Insight. The mount is pictured just like it sits in the car. The broken leg points toward the front of the car, the good leg towards the rear, and the short leg points upward. The lower right leg is cracked clear through. Both lower legs are compressed when the car is in any forward drive gear. That means the lower legs are stretched when in reverse. With a broken leg the motor mount will not dampen the engine when in reverse. I was thinking of taking some of that Urethane window caulking called 3M Window Weld and gluing the broken leg back into place, but more importantly adding a bridge from the top leg to the inner ring. That will help the reverse gear chatter and help hold the broken leg in compression and hopefully make it a bit more stable. A new mount is about $80-$100USD. So a tube of Urethane and some time is a good trade off. The motor and trans are balanced well so that the rear mount being removed does not require anything to hold the motor in place.
