starter problem
This has me stumped and need the experts again. When I bought the M1038 3 months ago, there was always a shrill sound when starting the engine from the starter. When I loosened the bolts holding the starter, I found 5 shims moving the starter at least. 1/4" away and the flywheel had new metal showing at the edge of the teeth instead of the normal rust everywhere else. I removed 3 of them and the shrill disappeared. However, when I give the engine gas to accelerate, the starter hits the flywheel. If I give minimum gas to accelerate slowly to get speed and cruise with very little gas, there is no noise. If I add shims, I will be starting at the edge of the flywheel again. And, the starter moves all the way back in.
Can anyone tell me what to look for in an adjustment or replacement? I would like to remove all shims to have good contact but not run into this problem.

If you have the correct starter, It sounds like you might have a cracked flywheel that is flexing when under load. Look for cracks around the crankshaft area.

The first time I reassembled my tranny and engine together I didnt do em tight enough and they started to seperate and it did ruine the fly wheel. The sound would come almost from directly under the dog house cover. Check the gap tween the engine and transmission and make sure they are snug.
This is what happens

I need to know the proper terminology.
Is there a difference between A1 and A2 starters? Some thought I had a wrong started installed. Just checking. -Peter

GM seems to flop back and forth with the Flexplate/Flywheel nomenclature over the years. The furthest back I have looked so far in my GM Manuals is 1971 and in that one and others they say that the torque converter on the Turbo 400 is bolted to a Flywheel. AMG uses the name Flexplate, but since they diden't sell any manual transmission equiped Hummers, there should be little confusion. Just be shure not to mention that you have a Humvee while you are at a Hummer Parts Counter.

some people don't ever learn. How many times have you seen errors in the TM's? Here's a suggestion if you think you have a flywheel; call up a parts store, any of them, and order one and see what you get.
This is childish ans silly. just bc you have made an error in nomenclature doesn't mean the world is going to end any time soon. I was simply offering up the correct terminology for all to use. if you reject it then fine sooner or later you will find the information useful.

J, it's sometimes called a Flywheel and sometimes a Flex Plate, even if it is used with a torque converter attached. It depends on what the particular manufacturer or org. wants to use. I just posted that TM page to show you that. Maybe in this instance the Military TM Writers thought army Mechanics were too stupid to know the difference, so they kept using a name that they were familiar with, so they woulden't start removing something from the front of the engine, I don't know, but it might be possible.
Schindop If you do actually need a Flywheel/Flex Plate for your M1038 Humvee or is that HMMWV, I can say that you probably won't get anywhere at an Auto Part Store. I don't think their parts catalogs are going to have a listing for you and you don't want to get the wrong part so I'd recommend calling up Kaskar. They have an on line catalog that is very conprehensive.

converter
I will post this on HMMWV wanted.
Problem with my starter is discovered: The converter used was a 3-bolt converter (civilian) instead of the 6-bolt required in the manuals. My thanks to all who supplied information for this. The flexplate is "flexin" to much. I will post in "wanted" for a source to buy a 6-bolt converter. Who would have thunk? (The "G" is great!)

I have had civilian vehicles that have the 6.2 and Turbo 400 combo and they all used six bolts to attach the Torque Converter. Maybe someone put a Torque Converter from a Gasoline application in your Humvee or maybe the 1/2 ton Pick up truck application used the three bolt attach method like the gassers, but I don't think so. There may be more than one stall speed for the available Converters too.
