    Just put in a new flywheel and a rebuilt starter. First of the flywheel I got LOOKED the same, but when the one in the truck was out the one I got had the converter bolts out farther. I have some cucv and hummer 6.2s. So could that flywheel be for a hummer? Second, My rebuilt started starts the truck a heck of a lot faster. why does a starter make so much of a difference? Do I need to put the shim back in? It seams to start fine. The bracket on the back of the starter is that really needed or can I just leave it off? Anything else that I should do whey I am there please let me know. thanks for the help in advance.

    Dunno about the flywheel.

    The recommendation is to put the shims back in. However, there is no guarentee that the shims that were in there were correct in the first place.

    You might have gotten a mini starter, or a gear reduction starter. The original 6.2 starter was a direct drive IIRC. Mini starters are great. Their gear reduction capability means that it requires less current draw, and can also start our trucks with less amps.

    Cranking speed is a big part of good starting. The faster it cranks the more heat is generated by the air being compressed faster. The faster you compress it, the hotter it gets, the easier it starts.

    Mine was a pain in the ass some days before I swapped in a new 28 MT reduction starter. Now it flash's up nice and quick. /forums/images/graemlins/thumb.gif

    I have the original 6.2 starter, just now rebuilt. Where did you get the 28 MT reduction starter? Sounds like a good investment. My truck is a pia to start on some days to, but it is better then what it was. What about the bracket on the back of the starter, is it needed? plmk thanks for the help guys.

    28MT from the parts store. They asked which type I wanted...so I asked for the gear reduction starter. Mine was built (or rebuilt I guess) by Bosch and comes with a 5 year warranty. The brace is quite necessary...

    No pn#...the receipt is so faded you can't read anything on it anymore./forums/images/graemlins/angryfire.gif

    It cost me approx $300 US at the time.

    I guess I'll have to go back and see what they'll do about my receipt situation...I still have 4 years worth of waranty left.

    I am running the gear reduction starter from a 6.5L diesel on my 83 6.2L The only mod necessary was that back bracket. If you get the 6.5l bracket you don't have to modify anything. It turns over 100% better. I haven't gone through the winter yet but it starts at 40* without the glow plugs.I got mine remanufactured off ebay for 150$ from some outfit in minnesota I think. They are listed all the time on ebay.
