Cutting the plate picture


Here's a screen grab from the cutting process. I have it in movie form but it pretty much looks like the picture with the noise of the saw going




I put the bolt holes into the transmission adapter plate by bushing the trans bolt holes with some thin metal then drilling through the bolt holes. Then enlarging them to the right size. On my trans the locating dowels are in the same location as a bolt hole so I drilled that through the bolt hole. Counterbored with the closest standard drill size to the dowel hole. Then used a rotary file (round dill bit like attachment with a flat bottom. Kind of like and end mill) in my drill to enlarge them slightly and I mean slightly enlarge the hole and cut a square edge at the bottom of the hole. Worked great.

As others have done I then put the motor spacer plate on and the trans adapter plate and assembled them so they were against each other but not bolted together. I then spun the motor to center the trans. Drilled and doweled the two plates together. Removed them and drilled and dowled them in centered area and cut off the excess metal. I found when trying to center the trans that the best way was to put it together WITHOUT the clutch and move it around until the LEAST drag was felt (trans input shaft rotating easily in the pilot bushing). There was too much play in the splines of the clutch which allowed it to float more than the spining it and testing for the least drag (putting the trans in first gear will also make the differences more noticable.) I actually did mine with just the front half of the trans and the input shaft since I had it apart. When located in it's finished position I could spin the input shaft easily in the opposite direction when the motor was on and running (with the nose of the input shaft engaged into pilot busing in the motor).

Not sure any of that information is useful. There are a number of good "how to's" on making adapter plates. I still would like to balance my flywheel adapter and maybe even the flywheel. However that'll wait until later. I think the next step will be to load the motor into the chassis and see how it fits. That'll have to wait though as I want to get some work done on one of my other vehicles first

Blower module

Blower module aka Blower resistor replacement for a 2011 Volt (Gen1)  22745409   First step is to remove the trim on the passenger door sill.  This is required as the right outboard screw holding the lower trim panel on is not accessible with the trim on.  Removal is simply prying it up and then back.  It just has tabs that click into the slots you can see here. The next step is to remove the lower trim panel. There are three screws.  (9/32 socket fits the head) One to the right of this picture.  One to the left.  Then one to the back center (toward the front of the car).  I'll try to circle these in yellow later.  The one in the middle was missing on my car.  Makes me think someone has been here before.   Once the lower trim panel is removed there is an air duct that needs to be removed.  This was missing on my car.  Apparently the person that was in here last...

1 Month with the Chevy Volt

Image
Today has been about month since we brought home the 2011 Volt.  We have put over 400 miles on it.  Only using the range extender once for about 7 miles.  The one time we used the range extender we were finally able to see how far the car would actually go on a charge.  Not just the predicted mileage. Keep in mind we live in the Appalachian mountains.  The roads are very up and down and never straight.  And on this run there were many sections of 55 MPH and we drove in sport mode (We always drive in sport mode).   And well it included a foot to the floor acceleration run from a stop light to 55 mph.  I'm sure that hurt the range.  We weren't seeing how far we could stretch the range.  We were just driving it like we would drive a car.  Anyway we got 42.3 miles on battery power alone.  Which seems right in the neighborhood of what was predicted for the car when it was new.  For a 7 year old car with a 125K miles I'...

Removing the volts front seats.

Image
Our Volt didn't come with heated seats.  For what we paid for the car we were willing to over look it.  But it doesn't mean we didn't want them.  We decided to add some after market seat heaters. To remove the seat from the car:  The seat belt needs to be disconnected from the seat.  to do that pry out the little circle on the plastic bit that connects the belt to the seat.  See the picture below.  Note how the cap stays attached at the bottom. Remove the bolt in the center remove the plastic half. Then simply remove the metal tab that the belt attaches.  Might need to slide it down slightly to get it out. You may also might want to remove the head rest.  It will give more clearance for removing the seat.  Raise the headrest then remove the plastic bezels at the base of the posts by rotating them counter clockwise. To remove the headrest from the seat there is a latch on both posts that must ...
