+ | ====== Starter Rebuilt Update ====== | ||
+ | ** By Tim Palmer, Green Country Corvair Group ** | ||
+ | |||
+ | All of us who attended the tech session this month found out something new about starters. Maybe the most important is that they are not that hard rebuild. We also found that many " | ||
+ | |||
+ | * **1-** The starter nose is no longer available from GM but is from others. Usually all it needs is a new bushing. Be sure to check the Armature shaft for scarring. If there is, it should be turned and an undersized bushing used. The housing is sometimes broken. This usually indicates a bad ring gear, but could also be caused by an improperly installed starter or one that is worn out. We have noticed some of the housing have a seal for the starter Bendix to keep out water I guess. This would probably be preferable for a Corvair you drive everyday. | ||
+ | * **1A*-** This gasket was missing from most of the starters.It' | ||
+ | * **2*-** This should be a pin with a snap ring to keep it in. Many rebuilders used bolts with a nuts. probably not a good idea. TIP: take note of how you install the pin. Remember the start is installed at a angle. You want to install it such that if the snap ring falls off the pin will stay in place. | ||
+ | * **5*-** This is the main wear item on a starter. All the ones we looked at were worn. Some rebuilders will turn them around to use the outer side of the pads. We suggest replacement since the cost is low and that insures full engagement. | ||
+ | * **7-** The solenoid should be taken apart and cleaned. The brass or copper parts should be buffed with a wire brush. It is very important this be cleaned for good electrical contact. The battery terminal can be turned around 180 degrees to expose a new wear surface. The contact ring must be cleaned thoroughly. | ||
+ | * **12, | ||
+ | * **15-18-** One of the main parts to fail. Beware of any aftermarket Bendix' | ||
+ | * **19-** This assist spring was missing from some of the starters. The spring is not shown in the 65 shop manual. The parts book is not much help. My Chilton' | ||
+ | * **20-** The armatures are usually good. Check with a meter as shown in the shop manual. Check for bad wear on the commutator and bearing surfaces. Black burned into the commutator indicates the starters has been hot and the commutator will have to be turned. Also check the solder joints to the commutator for loose connections caused by the starter getting to hot and throwing the solder out of the joint. | ||
+ | * **20A*-** This fiber washer is either missing or messing up on almost all the starters. It should be there to provide proper end play. | ||
+ | * **21-** This bushing in the end frame rarely shows wear since it is loaded lightly. A new end housing with a bushing already installed can be purchased. | ||
+ | * **26*-** Brushes should be replaced as they are a big wear item and cheap.They are easy to find since they are the same as most GM starters made. | ||
+ | * **28-** The fields are rarely bad. Perform the check with a meter as shown in the shop manual. Normally these are not removed to clean. | ||
+ | |||
+ | In general, follow the instructions in the 61 or 65 shop manual. Use the exploded view to make sure you have all the parts and that they go together correctly. You should bench test the starter after rebuilding to insure proper operation. This can be done with a set of jumper cables and a switch. Nothing is worst than to install a starter and then find that it doesn' | ||
+ | |||
+ | If you need to store the starter before you put it on your Corvair, it is a good idea to put in a large plastic bag with one of those moisture absorbing bags. The bag will keep spiders from building homes in your starter. The moisture absorbing bags will help prevent any rust from forming. | ||
