These threads provide the motor bearings with oil.\n\n<figure id=\"attachment_471\" aria-describedby=\"caption-attachment-471\" style=\"width: 348px\" class=\"wp-caption aligncenter\"><img fetchpriority=\"high\" decoding=\"async\" class=\"size-full wp-image-471\" title=\"Pinion Gear\" src=\"http:\/\/bentonelectronics.com\/wp-content\/uploads\/2011\/12\/piniongear.jpg\" alt=\"Hammond Organ Pinion Gear\" width=\"348\" height=\"227\" \/><figcaption id=\"caption-attachment-471\" class=\"wp-caption-text\">Make sure the motor spins freely<\/figcaption><\/figure>\n\nTo check the motor push the shaft that is exposed in and it should pop back out. If this movement is easy and free then the shaft bearings are oiled and OK. Also, a severely worn motor bearing here can cause problems with the motor spinning correctly.\n\nIf the motor is stuck, apply oil directly to the bearings and turn it by hand until it becomes free. You can also help free it up by pushing the shaft in and out. The return spring is very light duty so the motor would be considered free if it springs back after pushing in the shaft.\n\n<figure id=\"attachment_472\" aria-describedby=\"caption-attachment-472\" style=\"width: 525px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/bentonelectronics.com\/wp-content\/uploads\/2011\/12\/pinionclose.jpg\"><img decoding=\"async\" class=\"size-full wp-image-472\" title=\"Pinion Close\" src=\"http:\/\/bentonelectronics.com\/wp-content\/uploads\/2011\/12\/pinionclose.jpg\" alt=\"Pinion Gear\" width=\"525\" height=\"295\" \/><\/a><figcaption id=\"caption-attachment-472\" class=\"wp-caption-text\">Pinion Gear<\/figcaption><\/figure>\n\nThe next thing to check is the pinion gear which the start motor engages with when starting the generator. This is the lower and larger gear shown above. This gear rotates with the generator and also slides from right to left on it&#8217;s shaft.\n\nBelow you can see the pinion gear moved to the left exposing the smaller shaft that the pinion gear slides on. This sliding action is necessary to engage with the start motor. It is common for this pinion gear to get stuck either in or out causing the starting motor to be unable to engage properly. Simply slide it to the left, oil the shaft, and slide it back. After a couple of times it will move freely again.\n\n<figure id=\"attachment_473\" aria-describedby=\"caption-attachment-473\" style=\"width: 565px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/bentonelectronics.com\/wp-content\/uploads\/2011\/12\/piniongearmoved.jpg\"><img decoding=\"async\" class=\"size-full wp-image-473\" title=\"Pinion Gear Moved\" src=\"http:\/\/bentonelectronics.com\/wp-content\/uploads\/2011\/12\/piniongearmoved.jpg\" alt=\"Pinion Gear Moved\" width=\"565\" height=\"356\" \/><\/a><figcaption id=\"caption-attachment-473\" class=\"wp-caption-text\">Pinion Gear Moved<\/figcaption><\/figure>\n\nBelow are two shots of the pinion gear from the underside of the generator. The first view shows the pinion gear in the rested position. Notice the two springs on the pinion gear shaft. The larger spring right against the gear <strong>acts as a clutch for the pinion gear<\/strong>. The smaller spring to the left (in the tone wheel bin) is the return spring for the pinion gear.\n\n<figure id=\"attachment_474\" aria-describedby=\"caption-attachment-474\" style=\"width: 397px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/bentonelectronics.com\/wp-content\/uploads\/2011\/12\/pinionbottom.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-474\" title=\"Pinion Gear Bottom\" src=\"http:\/\/bentonelectronics.com\/wp-content\/uploads\/2011\/12\/pinionbottom.jpg\" alt=\"Pinion Gear Bottom\" width=\"397\" height=\"215\" \/><\/a><figcaption id=\"caption-attachment-474\" class=\"wp-caption-text\">Pinion Gear Bottom<\/figcaption><\/figure>\n\nThe next shot shows the pinion gear moved to the left.\n\n<figure id=\"attachment_475\" aria-describedby=\"caption-attachment-475\" style=\"width: 405px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/bentonelectronics.com\/wp-content\/uploads\/2011\/12\/pinionbottom1.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-475\" title=\"Pinion Gear Bottom 2\" src=\"http:\/\/bentonelectronics.com\/wp-content\/uploads\/2011\/12\/pinionbottom1.jpg\" alt=\"Pinion Gear Bottom 2\" width=\"405\" height=\"223\" \/><\/a><figcaption id=\"caption-attachment-475\" class=\"wp-caption-text\">Pinion Gear Bottom 2<\/figcaption><\/figure>\n\nIt&#8217;s a little hard to see but there is a flat spring pressing on the smaller motor gear.
