white90 Posted May 16, 2007 Share Posted May 16, 2007 The Rover oil pressure switch is ½ inch UNF with a spanner size of 22mm. The quoted pressure rating is 5.8 – 10.2 psi (nominal 7psi). These fail with monotonous regularity – even the OEM which IIRC is intermotor....part number 50600 (see below) Here are the complete range of oil pressure switches Part No. A/F Size Thread Pressure ( p.s.i.) 51150 24 1/8" BSP Taper 0.7-2.2 50820 22 1/8" BSP Taper 2.2-3.6 51140 22 1/8" BSP Taper 3.0-5.0 50750 22 1/8" BSP Taper 3.0-5.0 51100 22 1/8" BSP Taper 3.0-6.0 51110 22 1/8" BSP Taper 3.0-6.0 50740 22 1/8" BSP Taper 3.0-6.0 50810 22 1/8" BSP Taper 3.0-6.0 50700 22 1/8" BSP Taper 4.5-7.5 50800 22 1/8" BSP Taper 4.5-7.5 51196 24 1/8" x 27 NPTF 1.26-3.25 51010 22 1/8" x 27 NPTF 2.0-5.0 N.O.C. 51011 22 1/8" x 27 NPTF 2.9-7.3 N.O.C. 51000 22 1/8" x 27 NPTF 3.0-5.0 50620 13 1/8" x 27 NPTF 3.0-5.0 50530 22 1/8" x 27 NPTF 4.4-8.7 50540 22 1/8" x 27 NPTF 4.5-7.5 51060 22 1/8" x 27 NPTF 4.5-7.5 50670 22 1/8" x 27 NPTF 4.5-7.5 N.O.C. 50500 22 1/8" x 27 NPTF 5.8-10.2 - Standard sprite 51020 24 1/8" x 27 NPTF 6.5-8.5 N.O.C. 50650 22 1/8" x 27 NPTF 6.5-10.0 N.O.C. 50630 13 1/8" x 27 NPTF 10.0-13.0 50610 25.4 1/4" x 18 NPTF 2.0-8.0 50850 22 1/4" x 18 NPTF 2.9-5.1 50590 22 1/4" x 18 NPTF 2.9-8.7 51050 22 1/4" x 18 NPTF 3.0-5.0 50690 22 1/4" x 18 NPTF 4.5-7.5 51190 22 1/4" x 18 NPTF 7.5-11.9 50510 22 1/4" x 19 NPTF 2.9-5.1 50520 22 3/8" BSF 6.1-10.2 50680 22 3/8" BSF 17.4-29.0 50611 22 1/2" UNF 3.0-5.0 51170 22+18 1/2" UNF 4.5-7.5 50600 22 1/2" UNF 5.8-10.2 50950 22 M10 x 1 2.2-6.5 51031 22 M10 x 1 5.8-10.2 N.O.C. 50660 22+15.8 M10 x 1 7.5-10.0 50760 22 M10 x 1 7.5-10.0 51030 22 M10 x 1 17.4-23.2 N.O.C. 50970 22 M10 x 1 23.0-29.0 N.O.C 50960 22 M10 x 1 Taper 2.2-6.5 51197 24 M10 x 1 Taper 4.25-6.25 50550 22 M10 x 1 Taper 4.4-8.7 51015 22 M10 x 1 Taper 4.4-8.7 50710 22 M10 x 1 Taper 4.4-8.7 50951 24 M10 x 1 Taper 4.4-8.7 51040 22 M10 x 1 Taper 23.0-29.0 N.O.C. 50720 22 M12 x 1.5 0.7-2.2 50570 22 M12 x 1.5 2.9-7.3 50730 22 M12 x 1.5 2.9-7.5 50725 24 M12 x 1.5 4.25-6.25 50910 22 M12 x 1.5 5.5-8.5 50770 22 M12 x 1.5 6.0-8.0 50780 22 M12 x 1.5 7.5-10.0 50790 22 M12 x 1.5 7.5-10.0 50830 22 M12 x 1.5 7.5-10.0 51195 24 M12 x 1.5 Taper 4.25-6.25 50890 22 M12 x 1.5 Taper 5.8-10.2 50900 22 M12 x 1.5 Taper 7.5-11.5 51131 21 M14 x 1.5 2.0-4.0 50985 21 M14 x 1.5 2.0-4.0 50980 22 M14 x 1.5 2.2-3.6 50990 21 M14 x 1.5 3.5-6.5 50721 24 M14 x 1.5 3.5-6.5 51133 21 M14 x 1.5 4.25-6 25 50930 22 M14 x 1.5 4.4-8.0 50935 22 M14 x 1.5 4.4-8.0 50840 22 M14 x 1.5 4.5-7.5 50860 24 M14 x 1.5 5.8-8.7 50560 22 M14 x 1.5 7.3-11.6 50880 22 M14 x 1.5 8.0-11.0 51134 21 M14 x 1.5 28.0-32.0 50870 22 M16 x 1.5 5.8-10.2 50871 21 M16 x 1.5 5.8-10.2 50875 21 M16 x 1.5 10.5-14.5 51130 21 M18 x 1.5 4.25-6.25 51132 21 M18 x 1.5 4.25-6.25 50861 21 M18 x 1.5 6.0-8.0 50941 23 M18 x 1.5 8.0-10.0 50920 23 M18 x 1.5 8.5-11.5 50940 23 M18 x 1.5 8.5-11.5 Ian Link to comment Share on other sites More sharing options...
