    New 1000CCA battery's, all new 1 gauge cables, new terminals and connections, and of course a 28MT starter, and it actually starts without needing the glow plugs. Until today I didnt even think that was possible.

    I had done the battery's and cables last week, but because of my other project sucking down all my time, i never got arround to installing the new starter, until yesterday when heat soake caused mine to give up the ghost when i was 25 miles away from home. Luckily i got it started with WD-40, a powerstroke, and a 5th exide orbital battery. Unfortunately it fried the starter for good, but at least i got it home.

    All i have to say about the 28MT is WOW. I cant believe how fast it spins this motor over. Thank you CK5, because if i had never read about it here, i would have put a stock replacement in and spent more money doing it. I picked mine up brand new off ebay for $90 (not a bosch, though), which was $150 less than what autozone wanted for a remanunfactured duralast.

    Freaky how much more cranking speed the 28MT provides isn't it? :) Probably the best thing i ever did to my 6.2 so far.

    Yes it is, im amazed.

    Honestly after putting some mall terrains on it for street driving, and now having it actually start when i want it to, it almost feels like im only driving a 100K mile truck :D

    I can rememeber needing 4-6 seconds of glow time even when the motor was at operating temp, now I only use the GP's when it's dead cold, if the motor is even somewhat warm it'll flash up in less than 2 seconds with no GP's.

    My truck will start up with out glow plugs after sitting for 4 hours on a 70 degree day, also with in 2 seconds or so, with the stock starter and a single battery. I just used good quality 2 guage battery cables and a 6 ga cable between the battery and glowplug relay for the cold mornings...

    Cool deal. I'm kinda feeling out the starter thing, to find the best price vs. longetivety (sp?).

    You should have seen me running around the truck looking for my hammer, at the boat dock on a small lake, to beat the crap out of my Autozone starter that wouldn't stop :haha:

    Do you need an adapter to put one of these on a 6.2 from other years?
    Every time I've researched it they never list the older 6.2 engines. Mines an 85. Thanks

    My 6.2 is an '85 as well. The 28 MT bolts right up, but you will need a new support bracket. I'd guess the dealer or a parts truck would be best to find the little bracket.

    Or, you can do like me and cut and re-drill the old bracket instead of buying a new one.

    Other than that they just bolt right up, and getting the 28mt in is a easier than getting the OEM starter out.

    What is the difference between this 28MT and the stock starter? Is the 28MT just the starter spec'd for the later GM diesels?

    Could my stock 1990 Burb 6.2 have this starter already?

    Thanks!

    yup..

    From what I've read,they are a gear reduction style starter rather than a "straight" direct drive style one...not sure if the motor itself is a permanent magnet design or not--I'm thinking it is,but I havent seen one other than in pictures online...My "old" style starter seems to work good,cranking speed is not a problem(maybe my diesel has low compression!)..I had to replace the starter drive bendix on it when I first bought the truck,it would not stay engaged long enough to fire up the motor( I think the previous owner used starting fluid and the kickback ruined the starter drive bendix)...cost 35 bucks for a rebuilt starter drive,and only NAPA could get it!--all the other stores wanted 70 bucks for a new one,special order--a local dealer wanted 110 bucks! :eek: :yikes: ...

    I'll be getting the "new" style starter if mine croaks again--but mine was an AC/Delco rebuilt,and looked new inside!--guess they cheated and re-used the old starter drive--its gears were pretty worn too...but I think it will last a long time now-(I HOPE!)... :crazy:
