 Posted: Sat Jan 29, 2011 10:14 pm Post subject: Section 46 - Engine Mount Question |
 |
|
Hi there guys, I'm at the point of installing my engine mount as per Section 46, page 46-2 (Drawing Revision 1) and I'd just like to clarify the hole sizes and installation hardware for the engine mount please. I have amended my drawings from Revision 0 to Revision 1, so i think that I have the correct installation drawings for Section 46?
The instructions indicate to drill a 3/8" hole in the Firewall Assembly common to the WD-1001-D1 Dyna-1 Engine Mount, I did this. The drawing also makes reference to 6 x AN6-24 drilled bolts, which are used to attach the engine mount to the Firewall Assembly.
In my firewall forward kit I have kit 'EA DYNA BOLT I(O)-540 Motor Mount Bolt Kit' which appears to correspond to the hardware required to attach the engine mount. This kit contains the following hardware:
4 x AN7-26 Drilled Bolt, 7/16"
4 x AN310-7 Nut, Castle, 7/16"
8 x AN960 -716 Washer
4 x MS24665 -283 Cotter Pin
The above kit appears to be totally different from the hardware specified in the drawing, coupled with the fact that it is short 2 bolts, 2 nuts, 4 washers and 2 cotter pins and the diameter of the bolts are 7/16" instead of 3/8"?
Have I missed a drawing revision guys?
I'm hoping that you might be able to clarify this for me as I'm a little confused here.
Kind regards

Rev 1 12/5/08 is the version that I have, which I received with my finish kit this past spring.
I think you are confusing two different steps.
46-2 talks about how to fasten the mount to the firewall and all the required hardware is included in the finish kit. I just performed this task a couple weeks ago and the instructions are correct. There does appear to be some “magic” to get all the holes to line up appropriately. There was a thread about a month ago, which I can’t remember if it was here or on VAF, talking about this. My bottom holes didn’t align perfectly, but the 3/16” hole was within the circumference of the 3/8” hole. Fortunately, the motor mount kept the bit from wandering using the 3/16” hole as the center.
The parts you are referencing in the fwf kit are for attaching the engine to the mount. Two different tasks. These are used on page FF1-5. Here’s a snipet:

Thanks Kelly.
Is everyone drilling the 3/8" bolt holes in the firewall in one hit or step drilling them?
Its a very large step from the original hole to the 3/8" hole. I'm stopping and lubricating the drill bit as I go, but is slow going for each hole.

Pat

You really need to drill these with the mount in place, so that eliminates the step drill option. Like I mentioned previously, the engine mount does a good job of keep the bit in place if the original 3/16” hole isn’t quite centered.
We have the opposite problem at the moment. We’re experiencing a warm spell today of about 0 C :^) It’s been 10-15 degrees colder the last couple weeks.
