  • Page 8 Exposed rotating drive-shafts should be guarded. It is highly recommended by Darley to use safety rings around drive tubes. Especially near connecting u-joint crosses. Such safety rings would be sufficiently attached to the chassis frame and sufficiently strong enough to prevent a broken u-joint assembly from allowing a driveline to slide out from underneath the truck at high speeds while still rotating, causing severe personnel injury.

  • Page 22 WARNING: DO NOT USE THIS PUMP FOR HOSE TESTING OPERATING THE ENGINE After the pump has been primed, the engine speed should be increased gradually -- never jerk throttle wide open. Likewise, the engine speed should be decreased gradually when shutting down.
  • Page 23 Air leakage into pump while operating is usually indicated by a rattling sound in pump casing, miniature explosions in stream issuing from the nozzle, or by losing of prime when operating at very low capacities. The usual cause of leaky suction lines is carelessness in handling of suction hose. Bruising of hose threads by bumping against hard surfaces or sand in the coupling often prevents tightening of the joints up against the gaskets.
  • Page 24 capacity further, and usually sets up a vibratory motion and “water hammer” as the water surges in and out of the void spaces. When operating with a long suction line, the driving engine should be accelerated gradually, the discharge gates opened gradually, and the capacities of the pump should be held down to within the range of smooth performance.
  • Page 25 TESTING FOR AIR LEAKS Tests for leakage should be made with the suction hose attached and capped, discharge gate open, and all other openings closed tightly. Run electric priming pump with primer shut-off valve open, until 22” of Hg is shown on the gage. The vacuum should hold for no more than 10”...
  • Page 26 If pump is equipped with a heat exchanger, drain heat exchanger using gravity and vacuum drain on all trucks as follows: Close all open lines and drain cocks. Open cooler valve and open air vent at top or drain cock at bottom of heat exchanger depending on model. With the pump air-tight, open primer with engine running for about a minute and then close primer.
  • Page 27 Capacity of fire pump is measured in gallons per minute. The usual method of measurement is to determine the pressure of the jet of water leaving a given size of nozzle by means of a “Pitot Gage” from which the capacity is computed mathematically. A Pitot Gage consists of a small tube adapted to a point directly into the hose nozzle from the center of the issuing stream, the other end of the tube being connected to an accurate pressure gage.

  • Page 72: Common Causes Of Vibrations

    Installation Techniques Common Causes of Vibrations The three most common causes of driveshaft vibration are: Driveshaft Imbalance, Critical Speed, and Universal Joint Operating Angles. Driveshaft Imbalance Eliminate the potential for balance problems before you undertake any other measures. A driveshaft on a vehicle usually rotates at a higher rate of speed than the tire. For that reason, like tires, driveshafts should be balanced.
  • Page 73 Installation Techniques Maximum Possible Driveshaft RPM To calculate the maximum possible driveshaft RPM in vehicles having an overdrive transmission, divide the maximum possible engine RPM by the overdrive ratio. (See examples below.) Example 1: Max. engine RPM: 2100 Overdrive ratio: .79 2100/.79 = 2658 maximum possible driveshaft RPM Example 2: Max.

    Installation Techniques Universal Joint Operating Angles Every Universal Joint that Operates at an Angle Creates a Vibration Universal joint operating angles are probably the most common causes of driveline vibration in vehicles that have been reworked, or in vehicles that have had auxiliary equipment installed. Universal joint operating angles are a primary source of problems contributing to: •...
  • Page 75 Installation Techniques Reducing and Canceling Vibration A key point to remember about universal joint operating angles: To reduce the amount of vibration, the angles on each end of a driveshaft should always be SMALL. To cancel an angle vibration, the universal joint operating angles need to be EQUAL within 1 degree at each end of a driveshaft. On motor home applications and auxiliary transmission installations, the tolerance is 1/2 degree.
  • Page 76 Installation Techniques Single Plane and Compound Universal Joint Operating Angles There are two types of universal joint operating angles: Single Plane and Compound. Single Plane Single Plane angles occur when the transmission and axle components are in line when viewed from either the top or side, but not both.
  • Page 77 Installation Techniques Determining the universal joint operating angles on a driveshaft that is straight when viewed from the side and offset when viewed from the top requires the use of a special chart (See Angle Chart). In this type of application, the centerlines of the connected components must be parallel when viewed from the top as shown.
  • Page 78 Installation Techniques Compound Angles Compound universal joint operating angles occur when the transmission and axle are not in line when viewed from BOTH the top and side. Their centerlines, however, are parallel in both views. (See Fig. 5) Engine Trans. Axle Top View Parallel Centerlines...
  • Page 79 Installation Techniques True Universal Joint Operating Angle The True Universal Joint Operating Angle, which must be calculated for each end of the shaft with compound angles, is a combi- nation of the universal joint operating angle in the top view, as determined from the chart, and the measured universal joint oper- ating angle in the side view.

  • Page 80: Eliminating Compound Angle Induced Vibrations

    Installation Techniques Eliminating Compound Angle Induced Vibrations Compound universal joint operating angles are one of the most common causes of driveline vibration. To avoid theses problems, remember these important points: • When setting up an application that requires compound universal joint operating angles, always keep the centerlines of the transmission and axle parallel in both views.
  • Page 81 Installation Techniques Angle Size The magnitude of a vibration created by a universal joint operating angle is proportional to the size of the universal joint operating angle. Spicer Engineers recommend true universal joint operating angles of 3 degrees or less. Obtain the true universal joint operating angle, as explained above, and if it is greater than 3 degrees, compare it to this chart.

  • Page 82: Multiple Shaft Installations

    Installation Techniques Multiple Shaft Installations Multiple Shaft Set Up Recommendations In general, multiple shaft installations follow the same guidelines, except there are different recommendations for setting up the driveline: • For a 2-shaft application, set up the first coupling shaft (sometimes called a jackshaft) so that the universal joint operating angle that occurs at the transmission end is 1 to 1-1/2 degrees.
  • Page 83 Installation Techniques True angle Adjust the axle to be 1 to 1-1/2 on the same angle as the first shaft Center Bearing These angles will automatically be equal Figure 9 If there is an offset in the installation of the axle, make sure it does not create too large of a compound universal joint operating angle.
  • Page 84 Installation Techniques On applications having more than two shafts, mount the first coupling shaft as outlined in the preceding example, and each addi- tional coupling shaft at a 1 to 1-1/2 degree universal joint operating angle to the previous coupling shaft. Install or tilt the axle to the same angle as the last fixed coupling shaft so the centerline of the axle and the last fixed coupling shaft are parallel.

  • Page 85: Mounting A Midship-Mounted Pto, Pump, Or Auxiliary Transmission

    Installation Techniques Mounting a Midship-Mounted PTO, Pump, or Auxiliary Transmission When installing a midship-mounted PTO, auxiliary transmission, or midship-mounted pump into the main driveline of a vehicle, install it at the same angle as the transmission. Keep the offset to a minimum to reduce universal joint operating angles. Note: Do not make the universal joint operating angle less than 1/2 degree.
  • Page 86 Installation Techniques If there is more than one driveshaft between the device and the rear axle, install the driveshaft as outlined earlier with a 1 to 1-1/2 degree universal joint operating angle on the input end of each shaft. Then rotate the axle so it is on the same angle as the last fixed shaft.
