Pump/Engine Mounts

MAGNALOY'S PUMP/ENGINE MOUNTS are available for mounting SAE flange-mount pumps to gasoline and diesel engines with pilot mounting capabilities.  Four basic engine pilot mounting configurations are available from inventory determined by the pilot diameter. Optional sizes are available upon request.

Engine Mount Selection Method

  1. Check TABLES 2 thru 5 to determine pump flange size.
  2. Determine Engine Pilot Group from TABLE 14 (other sizes available, consult factory).
  3. Measure the pump shaft length from the shaft end to the flange mounting face and ADD to the engine shaft length measured from shaft end to pilot face. An additional 1/16 inch (minimum) is recommended for shaft end clearance.
  4. Refer to the appropriate TABLE (15,16,17,or 18) according to Engine Pilot Group determined in STEP 2 above and locate the applicable pump flange selection from STEP 1, above.
  5. Select mount length option (dimension "XM" in tables) based on the minimum length determined in STEP 3, above.
  6. Check for proper clearance between the mount inner surfaces and the coupling O.D. (dimension "Z" and "CL" in tables). Dimensional data for Magnaloy Couplings is shown in TABLE 1 for reference. A complete Magnaloy Coupling catalog is available upon request.
