AW11 MR2 Urethane Engine Mounts |
|
The motor mounts were replaced when I right after I bought the car. I had no choice really as the front mount ripped away from the chassis and almost killed me at high speed. I purchased new mounts from carparts.com and had the front mount rewelded.
When we replaced the engine in the spring of 2001 I noticed that the rear mount was showing some wear. So during the winter of 2001/2002 I am going to 'refill' the front and rear mounts with urethane. UPDATE January 13, 2002 I have made the decision to update my mounts using 80 Shore A Urethane. I have gone through 2 sets of mounts in two years. My clutch is putting too much strain on the stock rubber. I have started removing the rubber. I ordered the Urethane for us$21.00 from McMaster-Carr. Here are the latest images:
All of the original rubber was pulled from the old mounts. The steel bearing tubes were cleaned up. The center of the mounts were cleaned up. I bought 2 bags of sand and a tub with lid. The sand can be used for other stuff later. It is regular construction sand... nothing special. The Mounts were then taped up with duct tape. I then took the center bearing and placed it in the exact center. Took a hammer and made some indention's in the tape. And then cut a hole in the tape smaller than the bearing. I pushed the bearing through the hole, and centered it in the mount. I then placed it in the sand. The sand will support the whole assembly to keep bubbles from forming within the urethane. This is very important to keep the mount as strong as possible.
I then read the instructions and warnings about how this stuff can kill you if you breath the contents... but only if you live in California. I live in Virginia, so I must be safe. But I am from California, so I moved the whole assembly outside. I opened the can and poured in the whole container of hardener. Stirred it up very well, and then just poured it in. I had a bunch left over, so I filled up a Slurpy cup with the rest. This will be used to make isolators, spacers or anywhere it might look cool.
I checked the mounts after 5 hours. They are sitting in my basement shop. The temp is 65° F. They are solid enough to pick up. I am going to leave them in the sand for 24 hours. The destructions stated 72 hours for total hardness.
Reactions will be posted when I get the car completed. Links - http://www.raktron.com/misc/mt.htm http://www.geocities.com/CapeCanaveral/Hangar/6160/se-r/mounts.html AJ Perez states: Back to Parts Catalog |
