Fixing the Transmission

Porsche 914 EV Conversion

Well, these pictures are a little late, but here they are. I spent most of last week replacing the broken parts in the transmission. Here are the two replacement bearings from Pelican Parts ($400!)

T oyota created some excitement with their new Hybrid X vehicle that they unveiled at the car show in Geneva last week. It just might have plug in implications. Here is part of their press release on the new concept car.

AC Motor Controller Installed

Tim, happy to get the controller installed A closer view of the Azure Dynamics AC motor controller. After purchasing hardware from Home Depot to install the controller plate, I came home and drilled all the required holes for the mounting bolts.

The First Sawzall Cut for the Controller Plate

Porsche 914 EV Conversion

My first use of a Sawz-All. The hole for the motor controller plate. All the transmission pieces (waiting for new parts) covered up to prevent metal shavings from getting into them. The motor controller plate provided by ElectroAuto before being bolted and caulked in.

Make it go away! (The engine, I mean)

Porsche 914 EV Conversion

This morning, Jamie from Corvallis bought my engine and took it away, freeing up much needed garage space. Thanks, Jamie! Engine in Jamie's van with a bunch of extra parts. Me, enjoying my desperately needed garage space

Transmission Woes (More than I bargained for)

Porsche 914 EV Conversion

Today was an educational and humbling day. I appreciated having the new garage space after the engine went away. I started opening up the transmission because first and second gears were grinding badly and I wanted to see if I could replace the synchro rings.

Flywheel and Engine Mount Removal

Porsche 914 EV Conversion

I put the engine for sale on CraigsList and have to prepare it for delivery this weekend. There is very little space in my one-car garage so getting rid of the engine while keeping all the necessary components will be good.

Transmission Removed!

Porsche 914 EV Conversion

This was a big evening of figuring out how to remove the transmission with one person. First up was removing the rear portion of the exhaust system, shown here next to my trusty 34mpg 1994 Saturn. Someone else converted a '94 Saturn Wagon to an EV, but I'll keep mine!)

More engine drop pictures

More parts but no instructions or hardware.

Porsche 914 EV Conversion

This week has been a whirlwind and I haven't caught up on sharing all the pictures. Last Tuesday, I received another shipment from ElectroAuto. This one included the motor controller mounting plate (large black rectangle), its rubber mounting posts and the potbox and its mounting plates.

blogger issues and engine drop picture

Porsche 914 EV Conversion

Apparently Blogger thinks this blog is a spam site and is forcing me to type in characters with each post. This wouldn't bother me, except that it doesn't accept my character input as valid, even though I've tried a few times. I've put in a request to stop this, but it will probably take awhile.

Dropping the Engine

Porsche 914 EV Conversion

The engine just about a foot below mounting height. Engine pulled back about a foot. Hole left over in the engine compartment with dropped engine. Notice the belt that drives the air pump for the emission control system. Well, I worked for the last three hours to drop the engine out of the car.

Days 3 and 4

Porsche 914 EV Conversion

I spent yesterday (Saturday) disconnecting all the cables from under the car in preparation to drop the engine. The shift linkage was especially hard because it moved around so much. My friend John (above) held the shift lever still while I yanked out the linkage earlier today.

End of Day 2

Porsche 914 EV Conversion

Most of today was spent just taking the car apart. My friend Pete came over for lunch and we removed the front and rear trunk lids. We also drained the fuel tank by operating the fuel pump with a 12V gelpack battery and took out the fuel tank.

The Great Desulfation Experiment

Porsche 914 EV Conversion

Can one revive a mostly dead battery? Several internet sources say yes. Above is a picture of a heavily sulfated 8-volt golf-cart battery I acquired yesterday. It had a floating voltage of 7.85 when I got it and needed half a gallon of distilled water to fill it back up.

Bush Uses Alternative Fuels

Plugs and Cars

An imperiled attorney general, an unpopular war, a hung-over housing market and a presidential approval level of 32 percent: White House officials took all that into consideration and made their decision. They would have President Bush do another event promoting cellulosic ethanol. Thus begins Dana Milbank's story in the Washington Post today.

A few measurements to not forget.

While taking apart the transmission, I took some measurements with a digital caliper. These are probably different from other 914s out there, but I wanted to record them here in case I lose them amid the rapidly increasing paperwork.

What up with GM's Plug-in hybrid Volt?

Plugs and Cars

"GM tries to unplug Volt hype" is not the headline I've been hoping to see out of Motor City this spring. But there it is in a Detroit News Autos Insider piece today. Just weeks after announcing production, perhaps, in 2010, the industry's hometown paper lets us know this is no done deal. The Volt grabbed headlines, lit up online chat boards and dominated the buzz at the auto show in Detroit. There's just one problem: The Volt may never get built. GM continues to spread the gospel of the Volt.

More Thoughts on Battery Equalization

Porsche 914 EV Conversion

Lee Hart, an EV guru on battery maintenance and equalization, has graciously e-mailed with me regarding the best way to equalize batteries. He's currently working on upgrading his battery balancer (see link at right) to handle a wider range of battery technologies and applications. Lee convinced me that the flying capacitor approach that I originally thought would work is not practical in real world situations.

Let the Conversion. Begin!

Porsche 914 EV Conversion

I just got back from A & P Specialties where Alan replaced the suspension on the 914 and did a steam cleaning in the engine compartment. Without the battery weight and having the unaligned suspension, the car rides unstable and high. No matter, I'm going to start preparing to drop the engine this weekend. I ran out and got another floor jack and a water-proof label-maker so I can mark all the wires and hoses as I take them out. Today is the last day I will drive the 914 as a gasoline vehicle.

The desulfation experiment continues

Porsche 914 EV Conversion

On a more process-oriented note, the 8-volt battery sitting on the desulfator is up to 9.1 volts (from 7.95 volts), so I have warm fuzzies that the desulfation system is working somewhat. I'll wait until the battery gets up to 9.6 volts (float voltage) and see what the specific gravity is. If this experiment works, I might splurge and purchase a $500 super-desulfator and offer to desulfate batteries for the OEVA club.

Plug-in Hybrids in Toyota's Future, Jim Press Tells Reuters; Desires Joint OEM Battery Research

Reuters reports on an interview with Toyota North American President Jim Press that Toyota Motor Corp. is working on developing a plug-in hybrid vehicle and is open to joining with other automakers in battery development. Echoing its American counterparts Ford and GM, Toyota bemoans the unavailability of batteries which will take their plug-ins half as far as their own electric cars could manage just 5 years ago.
