6.2L Diesel Starter

I have a 1984 K5 with a 6.2L Diesel with starter problems. I know it is missing the back mounting bracket. I just want to know if this is the only problem. Right now when you try to start it the starter grinds bad. Does this start require shimming like other GM starter or is not in the right place becuase of the missing bracket?

Hi!

All I can offer is personal experience on this one...on a 1984 GMC Sierra C1500 6.2L pickup truck...

  1. Is your starter original?
  2. Have you taken it off and looked at it?

I don't know how much of a difference the third support bracket makes. I tested my starter with it off and didn't see a problem. The first two bolts are very important. Make sure they haven't sheared.

The starter on my truck had ground badly for years. It wasn't until the solenoid burned up that I decided to find out why. I dropped the starter to find that the casting around the drive assembly was broken and resting up in the area where the starter's shaft normally is located. It had just cracked off.

Upon dropping the starter I had it rebuilt by a good independent automotive electric shop. What I got back was a night and day difference from what I had brought in for repair. (Yes, it was the same starter...just a before and after.) Putting the "freshened" starter in place resulted in a noticeable difference. Starts were stronger with much less grinding. (I had to have the flexplate replaced in the truck as well...now it starts and cranks very nicely.)

I don't recall ever having any shims or other adjusting devices in place on my starter. It was just the three bolts and any applicable wiring.

I was given the truck because of the starter problems. Here is the story as I know it. It is originally a Military truck so it had 2 alternators and batteries and a 24 volt starter. It was converted over to 1 alternator and battery and 12 volt start before they bought it. They decided to hook up the other alternator and install another battery. This then supplied the starter with 24 volts. The claimed the starter died and broke one of the 2 bolts. They installed a new starter and unhooked the second alternator and battery. They were never able to get it to work right so they gave it to me. They're maybe more to the story that they are not admitting. I looked at the flex plate and it looks good the starter looks good. I plan on going to the Chev dealer today to buy the missing bracket and pick up a shim kit. Is there anything else to look at?

Yeah, it should have two batteries wired in parallel, pos to pos, neg to neg for increased amperage.

24 volt to a starter designed for 12 volt aint going to last too long. I got out of the service before we got rid of the Dodge junk heap 5/4 ton M880 4X4 and M890 4X2 trucks. These were 12 volt everything. Now then, if it got a radio rig slide in the bed like a slide in camper, then it got a 24 volt alt to run just the radio gear, the batteries for this were in the conex unit that held the radio gear. It was my understanding in talking with guys who were in after I got out, that the GM set up was the same, and specs here seem to agree with that,

Uncle Sam was trying to save money by using off the shelfcivilian vehicles with minimal modifications, such as not having everything24 volt. For what it cost for oneM715 5/4 ton 4X4 Kiaser "jeep" the services could get 2 M880 dodge 5/4 ton4X4s. Of course they got what theypaid for too. The 318 2 bbl was under powered. The electronic ignitionsystem that was supposedeliminate cold weather and wet weather starting problems was worthless inwet weather. The floor boardsrotted out because the rubber mat had a fiber isolation that stayed wet,also caused more than a few fireswhen it shorted out the high beam switch. The carter carbs were junk. Thefront hub set up on the 4X4was a pain in the butt to work on. Required special puller and press toolto change a rotor or bearing.Up untill this idea came about inventory was easier too. Every vehicle usedthe same head lamps, tail lights,fuel gauge, voltage gauge, alternator, you get the drift. Every vehicleused flat glass every were, made replacing bustedglass a cinch as well as easy to install bullet "proof" glass every where.Notice the HUMVEE has flat glass.2 different batteries covered just about everything with wheels or tracks.I digress Whitelightning
