After all of the critical measurements needed on the crankshaft were done, it was time to put it back into its home with some fresh bearings to continue the engine build. Since there was no noticeable wear on the crankshaft, standard-size replacement bearings were used along with an appropriate amount of assembly lube. The torque specifications for all of the main crankcase bolts are torque-to-angle, which requires you to set the bolt up with a relatively low torque setting first, then finish with a final turned angle using an angle meter. Digital angle torque wrenches are great tools, but can be fairly expensive for the home mechanic. I’ve been using these manual angle gauges and although they take a little longer to set up on each bolt, I’m happy with the results and no batteries required. After using the proper torque sequence, the crank is in, spins nicely and we’re
We go to a lot of shows a year. The slammed look is popular, most presumably because it makes a car look more performance oriented. I mean, in general full blown race cars are very close to the ground. That keeps a lower center of gravity and ensures the least amount of airflow is allowed underneath (thus reducing lift). The interesting part about stancing out a car is that, while it might actually handle better on a race track if you know what you are doing and your alignment is good, on public streets the utility of this is nearly non-existent, and even extremely inconvenient depending on your environment. I’ve noticed an interesting trend in European car shows over the years that people are looking for something different. This almost always involves a sawzall and a MIG welder, we’ve all see Monster Garage. Chopped Euros, a Ute if you will.
After a very cold New England snap, a January thaw has reminded me that the racing season is fast approaching and we better get back into the shop! The engine block came back , hot-tanked and bored for our forged Wiseco pistons. These pistons have thicker top ringlands and the forging process gives superior strength and durability over the hypereutectic factory ones. With the all the bottom end saab performance parts here, let the build begin. First thing I want to cover is the current development of parts in our balance shaft delete kit, in progress. Before I even get into sizing up the new bearings and assembling the crank, I wanted to take a look at the balance shaft and engine timing system. But, we probably should talk a little about the purpose of balance shafts first. Balance shafts are weighted shafts that run off the crankshaft in order
We fully endorse always switching to winter tires when the snow falls, but with many new cars, TPMS sensors can be a burden. Having to take your car to a dealer to program your car not only costs money, but also time. On the new generation Saab 9-5, however, as long as you have working pressure sensors it is quite easy to reprogram them yourself without any additional tools. All you need is a way to let the air out of your tires, a way to fill your tires back up, and a tire pressure gauge. In about 5 minutes, The NG9-5 TPMS will read correctly at all four corners once again! First set your parking brake and start the car. On your left control stalk, clear any messages and go to your vehicle information menu. Scroll to the screen that displays the tire pressure sensing and hold down the
When you buy a shiny new set of brakes, it’s pretty exciting to finally get rid of that horrible vibration, or terrible squeaking. However, if you’re not careful you can be revisiting the problems faster than you think. A customer recently asked a question about why his BMW 740il was shaking when applying the brakes. Almost always, a brake jutter or vibration through the brake pedal is the result of uneven wear on the brake rotors at the end of an improper brake pad bed-in. Because of the nature of the friction material, there are a few crucial things to keep in mind when you finish your brake job. Read on to learn how to avoid all of that after installing your next disc brake kit. Why do I have to bed-in my brakes? The key concept to understand when discussing brake pad brake in (also known as bed in,
