Cardan (cross) type universal joint operation is typically designed to be in a range of 1 to 3°, figure 1. A cardan type joint can operate for short periods of time at angles up to approximately eight degrees. Angles that are not within the desired range will cause drive line vibration and significantly shorten the life of the universal joint. Vibration that is created by incorrect u-joint angles is usually most noticeable at low speeds, under 40 mph., under load or acceleration. If a problem with u-joint angle is suspected perform the following basic inspection procedures. 1. Rotate the drive shaft to check for binding, or misalignment of the cross or bearing cups. 2. Check that all surfaces are clean. 3. Check the condition of the motor and transmission mounts. Broken mounts are a frequent cause of drive shaft vibration and are often overlooked. If these conditions are satisfactory a preliminary check of angles can be made with an inclinometer. Before attempting to measure angles ensure that tire air pressure is correct, that the vehicle is at the correct trim (chassis) height, and the ground surface is level. 1. Measure the angle of the front slip yoke by placing the inclinometer on the bottom of the bearing cup, figure 2. Position the inclinometer on the clean flat surface of the bearing cup, level the bubble and note the reading. 2. Measure the drive shaft angle, as shown, and subtract the smaller number from the greater to determine the angle. 3. Repeat the same procedure on the rear u-joint and pinion input shaft.

ROTATING ENGINE STANDS 1. Overall visually inspect stand for any signs of wear and fatigue. 2. Lubricate spindles and gear box as referenced in vendor literature if equipped. 3. Inspect anti-rotation locking mechanism if equipped. 4. Install weight equal to engine weight to the engine stand for approximately 2 min. 5. Rotate weight set 360º in both directions if equipped. Operation should be free of binding and/or catching during rotation. 6. Dismantle fixture and visually inspect stand for any signs of wear or failure. Any item, which does not successfully pass the test, is to be rejected and discarded or returned to Tronair for evaluation. Load Cell Data Load Cell Display Cylinder/Pump Eyebolt 2x4 Wood Block Install Weight To Stand 08-2030-0000 AND 08-2034-0000 1. Install engine stand test fixture. 2. Position beam assembly in the center of the engine stand. 3. Tighten beam locks evenly, until the beam assembly is locked in place. 4. Position engine stand over eye hook in floor. Line eye hook directly under pull point of the test fixture. 5. Install 2 x 4 inch block under wheels and lock stand in place. 6. Attach load cell, pull cylinder to eyebolt. 7. Put engine stand through two cycles of loading the engine stand to 3,000 pounds (2,667 psi on gauge). Hold for 30 seconds then release load. 8. Inspect all welds and joints for signs of distortion; if no defects are found, the engine stand is good. 9. If defects are found discard or return to Tronair for evaluation.
Power from transaxle is transferred to driving wheels by 2 axle shafts. Both axle shafts use Constant Velocity (CV) joints at inner and outer ends. CV joints are enclosed in CV boots, and connected by an intermediate shaft. Intermediate shaft is splined on both ends. Retaining rings retain intermediate shaft in the inner and outer CV joints. A retaining ring retains inner CV joint stub in differential side gear. Outer CV joint stub is splined into wheel hub, and secured by a spindle nut. Left axle has a dynamic damper to reduce vibration. The following are possible types of Constant Velocity (CV) joints used on axle shaft: Birfield Joint (BJ), Double Offset Joint (DOJ), Rzeppa Joint (RJ) and Tripod Joint (TJ). Determine type of CV joint used prior to disassembly. See AXLE SHAFT SPECIFICATIONS table under INSTALLATION. Note type of boot and location prior to removal. See BAND & BOOT APPLICATION. Install a NEW retaining ring each time axle shaft is removed from transaxle.

This procedure will require the use of a hand operated vacuum pump with a vacuum gauge. If you do not own one it can often be rented or borrowed from most “big box” parts stores. (Note: 18”HG is the minimum engine vacuum at idle in gear to effectively operate a vacuum booster 1) Remove vacuum hose from check valve on booster. Place hose from vacuum pump onto check valve and draw booster to 20” of vacuum. 2) Let booster sit with vacuum applied for 5 minutes. If vacuum does not stay steady at 20” it is faulty and needs to be replaced. If vacuum does hold steady at 20” proceed to step 3. 3) With 20” of vacuum in booster depress brake pedal once and release it. The booster should transfer some but not the entire vacuum in reserve. Depending on how hard the pedal is depressed it is normal to see 5-10” of vacuum depleted from reserve. The most important thing is to ensure the booster does transfer vacuum but does NOT transfer the entire vacuum in its reserve. If vacuum remains at 20” OR goes to zero the booster is bad and will need to be replaced. If vacuum transfer is within the above parameter proceed to step 4. 4) Once again draw booster down to 20” of vacuum. Go inside car and depress brake pedal and hold down for 30 seconds. You should see the gauge drop slightly and then hold steady. Vacuum should stay steady as long as you are holding the pedal down. If vacuum drops while pedal is being held down the booster is faulty and will need to be replaced.
CONTENTS, PART I - Consists of the bleeding procedure for the Hydraulic Brake Booster only. The Hydraulic Brake Booster works in conjunction with the Power Steering Pump and the Power Steering Gear. CONTENTS, PART II - Consists of bleeding procedure for the Brake System. The Brake System consists of the Master Cylinder and the Wheel Cylinders. The Hydraulic Booster System uses power steering fluid. IMPORTANT! The Brake System uses hydraulic brake fluid. THESE SYSTEMS ARE SEPERATE! USE OF THE WRONG FLUID TYPE WILL CAUSE SEAL DAMAGE TO OCCUR. DO NOT MIX THE TWO SYSTEMS! PART I BLEEDING PROCEDURES FOR THE HYDRAULIC BRAKE BOOSTER 1. Fill power steering pump reservoir with power steering fluid. 2. Start engine and run for approximately two seconds then shut off engine. 3. Check fluid level; add as required. 4. Repeat steps two and three until (power steering reservoir) fluid retains constant level. 5. Raise the front of the vehicle until the height has cleared the tires. 5-a. Run engine at 1000 to 1500rpm. 5-b. Depress brake pedal several times. 5-c. Turn steering right and left, making light contact with wheel stops. 6. Turn the engine off, recheck reservoir fluid, and add if needed. 7. Lower the vehicle and repeat steps 5-a, 5-b, 5-c and 6. 8. If pedal is up and firm, the vehicle is ready for road testing. 9. If reservoir fluid is extremely foamy, let the vehicle stand with engine off for one hour, then recheck.

Race Day Checklist By: Steven Miller – March 2012 Last month’s article explained the tapering phase of a training plan. This article will provide you with some trips and tricks to make your race day as stress free as possible. You may have heard of the 5 P’s, Prior, Planning, Prevents, Poor, and Performance. Nothing could be truer than when getting ready to race. You’ve done all the hard training to get your body ready. You followed a methodical and disciplined training plan; don’t jeopardize your race by making avoidable mistakes on race day. This starts with preparing you race-day gear. I strongly urge you to do this the night before so you are not scrambling in the morning when nerves are already revving at an all-time high. It starts with the weather. Know what the weather forecasts are for race day and prepare accordingly. Here are some ideas:...
It is a never-ending theme for motorcycle and automobile manufacturers, for whom the Machine Tool Division of Mitsubishi Heavy Industries, Ltd. (MHI) manufactures and delivers gear cutting machines, gear grinding machines and precision cutting tools, to strive for high precision, low cost transmission gears. This paper reports the recent trends in the automobile industry while describing how MHI has been dealing with their needs as a manufacturer of the machines and cutting tools for gear production. process before heat treatment. A gear shaping machine, however, processes workpieces such as stepped gears and internal gears that a gear hobbing machine is unable to process. Since they employ a generating process by a specific number of cutting edges, several tens of microns of tool marks remain on the gear flanks, which in turn causes vibration and noise. To cope with this issue, a gear shaving process improves the gear flank roughness and finishes the gear tooth profile to a precision of microns while anticipating how the heat treatment will strain the tooth profile and tooth trace. After heat treatment, it was usual only to finish the portion of the gear that accommodates a bearing.
