2 piece driveshaft operating angles

Type the words into your computer search box. Some details are 9", 4 link suspension with bags, 2 piece driveshaft. RULE 2: UNIVERSAL JOINT OPERATING ANGLES ON EACH END OF A DRIVESHAFT SHOULD ALWAYS BE EQUAL WITHIN 1 DE GREE OF EACH OTHER (ONE HALF DEGREE FOR MOTOR HOMES AND SHAFTS IN FRONT OF TRANSFER CASE OR AUXILIARY A negative driveline slope points down, while a positive driveline slope points up. Using your Spicer Anglemaster® II or Anglemaster® Pro digital driveline inclinometer, determine the operating angles by placing the instrument on the driveline components. Thanks for the help. Mr 42. To obtain additional operating angles, push the "Alt Zero" button again, and then repeat the above process starting at the second slope (Slope B as the Alternate Zero and measure Slope C to get Angle B). there was a big thread about 2 piece driveshafts a few months ago, i posted a bunch of info on there, id search for it. If the driveshaft is a 2 pc or 3 piece assembly, all sections should be balanced together. For vehicles equipped with a two-joint drive line system, the following chart can be a helpful aid in determining the optimum operating angles. Normally a Double-Cardan style driveshaft is used in applications where it is not possible or practical to properly align the ends of … MEASURING DRIVELINES ANGLES STEP-BY-STEP Place a spirit level protractor on the driveshaft about halfway between the transmission and the Differential. Phasing theory says all bearing surfaces must be in line, front to rear, within 1/2 degree. One Piece driveshaft having a U-Joint and gearbox yoke at the front, and another U-Joint with the pinion yoke at the rear. Angle setup for two-piece shafts is similar to the one-piece. Nowhere does it say make the flanges parallel. I am convinced, of all 57 and earlier Studebakers with 2-piece driveshaft, the worst vibration occurs in 56J (and maybe SkyHawk). “You have to have some angle, a minimum of 1/2-degree, or the needles will brinell the surface of the u-joint, cross-bearing journal. Cardan, or universal joints, are the most common and widely used in single- and multi-piece driveshafts with operating angles lower than about 15 degrees. The wrong angles anywhere in your vehicle will wreck havoc on any bearings and sealing surfaces. The first spot is the transmission angle and second is the shaft's angle. Thanks for the help. I am still trying to figure out how subtracting the first two operating angles gives you the last operating angle needed, but if you Agree, phasing for Studes is a mystery. The two piece driveshaft keeps those working angles to less than 4 degrees, more than that will cause premature u-joint failure – Move More Comments Link To Top Aug 6 '13 at 14:55 Great answer! pinion angle 2 piece driveshaft Dually Suspension Dually Tech views 23440 replies 35 following 9 roadrage41 ... You should be about 1.5 work angles at each end of the second shaft. actually your wrong.on a 2 piece shaft, the trans angle and the rear pinon should be parallel and the angles of both shafts at ride height should equal 0 degrees, which is how high or left to right you set your carrier bearing. When checking driveshaft angles, be sure all tires are inflated to their normal operating pressure. The reason is their fiberboard headliner, which reverberates the driveshaft vibration throughout the car. The assy manual is one. The information below is a step by step guide on how to use the Anglemaster® in measuring driveline angles to avoid vibration … at the maximum operating speed to a ISO 1940/1 G16 specification. Universal joint operating angles on each end of a driveshaft should always be equal within one degree of each other (one half degree for motor homes and shafts … The Anglemaster® can be used wherever there is a need for a precise measurement of angles and slopes. Find the difference between the two readings and this will be that u-joint’s working angle. The Anglemaster® can be used wherever there is a need for a precise measurement of angles and slopes. Multiple piece driveshafts X have a 3 degree maximum operating angle. Constant Velocity (C.V) (Double Carden) Driveshafts: The real benefit to a C. V. (double cardan) drive shaft is smoother operation at higher operating angles and longer life. To calculate operating angles with the Spicer Anglemaster® II or Anglemaster® Pro, follow these five easy steps: NOTE: For maximum universal joint life, angles should be 3° or less. Lowered my '65 Chevy truck and trying to understand pinion angles. Begin with the transmission and work toward the axle. Driveline angles should be equal to or within 1° of each other. Ideally, the operating angles on each end of the driveshaft should be equal to or within 1 degree of each other, have a 3* degree maximum operating angle and have at least 1/2 of a degree continuous operating angle. bearing kit. For more info go to http://www.macsmotorcitygarage.com/2014/07/26/video-driveshaft-angle-and-phasing/ I would be happy to email the page to anyone interested. Ahh, thanks for that explanation on the two-piece shafts, i woulda never figured that out on my own. Ideally, the operating angles on each connection of the driveshaft must: X be equal or within one degree of each other. That’s because the wrong driveline angles can cause excessive vibration, which eventually leads to noise, premature wear, and eventually component failure. Number-3: U-joint operating angles should not be larger than 3-degrees. It is considered either positive or negative depending on whether the slope points up or down when viewed from the transmission toward the rear of the vehicle. Scientific research, appliance repair and installation, machinery, woodworking, aerospace, marine, motion picture equipment, bicycle repair, and physical therapy are just a few of the possible applications. The information below is a step by step guide on how to use the Anglemaster® in measuring driveline angles to avoid vibration problems associated with incorrect driveshaft and u-joint working angles. “If your driveshaft operating angle is too small, there will not be enough rotation of the needles in the u-joint caps and you’ll wear out your bearings due to lack of lubrication,” Dick explained. Two-piece shafts with u'joints are also more sensitive to changes in angle due to sags in the above rubber components. The easiest way to do this is to mount the front shaft section so it … Also remember to check driveshaft angles while the vehicle is unloaded, and again when it is loaded. The movement makes an X … Driving conditions too extreme for driveshaft Increase driveshaft strength. Terms of Service. By using your smartphone as a measuring device, the App will calculate each universal joint angle and provide an overall driveline operating angle. Discussion in 'The Hokey Ass Message Board' started by mugsy, Dec 20, 2005. Read and record the angle shown on the protractor scale and note whether the driveshaft points up or down at the front. To find the working angles follow these steps: Place an angle finder on the bearing cap and take note of the reading. Ideally, the operating angles on each end of the driveshaft should be equal to or within 1 degree of each other, have a 3 degree maximum operating angle and have at least 1/2 of a degree continuous operating angle. The slope at which a driveline component is installed is a slope of inclination. Record the angle as “3 degrees up” or “2 degrees down,”etc. Even factory rear axles can droop over time and may require you to correct the angle. ). Greg Frick Jul 31, 2002 This can tell you a lot about operating vibrations that are only present under certain conditions. Number-2: If you are to achieve cancellation these U-joint operating angles on each end of a driveshaft should always be equal (within 1-degree), but opposite of each other. My question is how do I set my pinion angle with a 2 piece drive shaft and do I need to set this at ride height or what. To obtain the operating angles of your total driveshaft requires making measurements of the transmission slope, secondary driveshaft slope (if present), and axle slope. RPM is the main factor though in determining maximum allowable operating angles. Some GM cars & trucks ran a CV type double U joint and that cures most angle problems, does this truck have one? 4. To calculate the residual angles of the drive line, operators can refer to Society of Automotive Engineers (SAE) publication AE-7 (Section 3.1.1, Cardan or Hooke Universal Joint). You can change your pinion angle or if you have a leaf spring suspension, you can buy leaf spring pinion angle shims like the ones here and correct the angle. This is a Double Cardan Joint, which is essentially two u-joints mounted to an intermediate center yoke. The engine is shown down 2.40 degrees with respect to the front driveshaft. Scientific research, appliance repair and installation, machinery, woodworking, aerospace, marine, motion picture equipment, bicycle repair, and physical therapy are just a few of the possible applications. Thanks for any info on this. Search, Identify and Order Parts - DanaAftermarket.com. (Angle A, Angle B, Angle C). If your second driveshaft-operating angle is out more than 1-3 degrees, you'll need to fix it. vehicles equipped with a one-piece driveshaft as viewed from the side of the vehicle. © 2021 Dana Limited. What a double cardan will do, is split a universal joint operating angle into two separate angles that are exactly one half of the original angle. The operating angle of a u-joint is the relationship between two slopes, such as the transmission slope and the tube slope. Park the vehicle on the surface which is as nearly level as possible both from front to back and from side to side. Copyright © 1995-2020 The Jalopy Journal: Steal our stuff, we'll kick your teeth in. Tons of helpful info will appear. NOTE: Repeat this step X You may also view the "Measuring Driveline Operating Angles" video for free or purchase the DVD with a credit card for $10 + shipping and handling. Although it comes with a 2-piece driveshaft, many owners switch to a 1-piece driveshaft after installing a suspension lift. Proper driveline operating angles are critically important to prolonging the service life of your driveshaft, U-joints, bearings, and seals. Driveshaft Angles The following information applies to street rods that are driven on the street by drivers who travel for fun and appreciate comfortable rides. The display will read 0.0° and the "Alt Zero" button indicator will flash. The reading obtained is the operating angle of the two slopes (Angle A). Driveshaft Angles The following information applies to cars that are driven on the street by drivers who travel for fun and appreciate comfortable rides. I understand that if angle at output shaft of tranny is say, 2 degrees (whether it be up or down), the pinion angle should be equal yet opposite. All three working angles should add up to zero. The Driveshaft flanges should be parallel, or in your case the rear axle should point 2 degrees up, so when you drive the axle will turn down resulting in a Zero degree setup. Mr 42, Dec 20, 2005 SHARE POST #2 You will need to set it up at ride height, and have the engine/trans, carrier bearing, and rear-end mocked up to get the proper angles … I have owned, worked on and test driven driven probably 10-12 of the 56Js, and the only ones Place the unit on the first slope (Slope A) and allow the reading to stabilize approximately 10 seconds. About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features (You must log in or sign up to reply here. High angles combined with high RPMs result in serious vibration problems and reduced u-joint life. The engine and the rear both point down and the required settings are very critical and precise. It shows the specs and specifies the pinion down by 3 degrees or so with respect to the rear driveshaft. Privacy Policy. The slope you are using will be the new reference. All rights reserved. The reason for a two piece, driveshaft is to reduce the angle between the gear box and the rear axle. If you imagine two lines parallel to each component, the angle where these two lines meet is the operating angle. Move the unit to the next adjacent slope (Slope B). Change to a 2 Piece or aluminum driveshaft. GM never knew that!! I would not be so sure of information unless I had a good source. Rotate the driveshaft 90° and repeat step one. The question still has not been answered for a 2 piece dirveline. See how to make your driveshaft stronger. As a driveshaft turns at a given angle, the joint moves in a forward to back motion.
