| ====== REF: Tools - 168 ====== | ====== REF: Tools - 168 ====== | ||
| - | ====== Dremil Type Rotary Tool ====== | + | ====== Bulb Type Pressure Tester ====== |
| - | A Dremil tool has many uses from cutting to polishing metal. Always wear a face shield when using this tool. \\ | + | Below is a bulb type pressure tester for testing the carburetor needle seat valve as referenced in TSB #564. \\ |
| - | It operates at a very high speed and tiny pieces of the cutting bits and the metal will hit your eyes faster than you can blink. \\ | + | It's for use in testing the seat valve of Tillotson carburetors used on 1966-later Sportsters and 1967-later Electra Glides. \\ |
| - | It's good for cutting carbon & stainless steel, shortening bolts, shaping metal projects etc. \\ | + | [[techtalk:miscres:miscres05#tsb_550-599|Click Here]] to go to the TSB page, scroll down and click on the "Y" next to TSB #564 to download the bulletin. \\ |
| + | The bulletin was an attempt by the MoCo to diagnose a simple needle/seat issue and replace if needed at the dealer level. \\ | ||
| + | (instead of sending the carb back to the factory for a warranty claim) \\ | ||

| - | + | Per the service bulletin. it's installed on the fuel inlet fitting with the vent plugged. \\ | |
| - | ====== Uses ====== | + | Squeezing the bulb adds pressure to the inlet and the gauge shows how much is added. \\ |
| - | + | A moistened needle and seat should hold app. 1 to 1·1/2 psi and release at approximately 3 to 5 psi. \\ | |

| - | |{{:techtalk:ref:tools:heatshield_strap_by_graywolf.jpg?direct&300|}}| | + | The gauge is for low pressure (15psi max) which shows a more accurate reading than higher pressure gauges. \\ |
| - | + | ||
| - | Usually, cutting the end off a bolt requires sanding / filing the cut area to deburr / chamfer the end. \\ | + | |
| - | However, the Dremil tool cuts at a high speed with a thin cutting disc. \\ | + | |
| - | Keep the cutting blade perpendicular to the threads while cutting and, most of the time, deburring the cut end is optional or at least minimal. \\ | + | |
| - | There is no need to install a nut and back it off the threads as you would normally do when using a hack saw or grinder. \\ | + | |
