Last month I installed a gear reduction starter. Seems ok so far. Some positives, some negatives. This is the one I used: Rareelectrical 24 VOLT GEAR REDUCTION STARTER COMPATIBLE WITH 92-04 AM GENERAL HUMMER HUMVEE 5.7 6.2 6.5 DIESEL 5744719
Here is the good, the bad and the ugly of the gear...
Not to restate what others stated, but if you want to try to get yourself out of it on the cheap without other heavy equipment, and there is a tree or something you can anchor to not too far away, you and use a come-along with some heavy duty straps.
Takes forever and not pleasant in the mud...
I figure I would post this in case someone like me wants to use a double pole rocker switch to manually control their fan clutch based on @Mogman excellent drawing.
Like Mogman indicated, I ran three 18 guages wires under one jacket into the cab.
I used a "Waterproof Rocker Switch Toggle...
These are not the products the military uses, so no HUMVEE tax from the vendors, but is what I used when I installed a 24V Serpa. Great winch BTW!
For the protective coating, search for "NOCO NCP2 CB104 4 Oz Oil-Based Brush-On Battery Corrosion Preventative, Corrosion Inhibitor, and Battery...
Not to hijack this older thread, but one of the last maintenance items on my M998 I got last year was to to replace all the belts and I just started experiencing belt squeal after repairing the AC on my 92 M998, with 6.2 and generator. Mainly the AC belt, but I figured I would confirm the part...
and you really need a bunch of specialized (expensive) equipment, like GOOD gauges, vacuum pump, leak detector. and you really need a way of recovering refrigerant unless you like pissing off the greenies. Actually, the basics can be "borrowed" with a large deposit from AutoZone. But it is so...
Just to add my 2 cents, having done this twice in the last few months... Use a third jack with a block of wood on the transfer case. It helps get the right angle so the whole assembly mates up to the engine...
And for the tranmission jack, don't use the cheap mechanical tranny jack from Harbor...
Excellent suggestion. Why didn't I think of that?
When I briefly short the terminals, the starter does indeed spin. So the starter is ok.
I'll investegate some more once I get a good VOM.
Well, got a new VOM and of course the Chinese POS was no good out of the box so I am waiting again on replacement. Even the Fluke ones that are hundreds of $ are Chinese.
In the meanwhile I did check all the battery connections and I did find one loose terminal but tightening it up did not fix...
Another update on the gear reduction starter.
Found that the two piece torque converter cover, the part that covers the starter - the holes won't line up with this starter. So I'll have to look at how to solve that.
The starter seems to be working well. Yesterday, I replaced the leaking...
Another update on this gear reduction starter. I decided to give it a try, and keep the rebuilt original as a spare.
Still a PITA to install even though it is less than half the weight of the original. Good news is all the original wiring reached after a bit of fiddling. The only modification...
Bit of an update.
I hoped I could pull the tranny back far enough to R&R the flexplate and avoid dropping the tranny completely but sadly, I could not move it far enough back because the tank and muffler prevented that. So I had to drop the tranny. :cry:
I received the gear reduction starter...
Thank you. Reading a bit more, I see a gear reduction starter will have problems without the proper front support bracket. I see GM part number 23502557 might be the correct part for a gear reduction starter on a big block GM engine, 454 gas or 6.2 or 6.5 diesel.
I have to look at the block...
Indeed I am not see much talk about using a gear reduction on a HMMWV.
Questions I see that were asked include:
Do you use the same shim?
Will the existing wiring reach?
Do you need a different front support?
I see they offer it on Amazon and it is returnable. I'm thinking of trying it and...
The HotRod guy like the gear reduction starters because they are:
lighter, less weight = go faster
smaller, easier to fit headers
I stumbled on to this. Wondering if the wires will reach? Do I use the same shim?
Wondering what you guys think...
Thank you for that. I now will take my starter to a rebuild shop in town and have them test it and install a new gear. I am sure if I tried, I would get it apart, but not back together!
One other question. While I am in there, I may as well replace the flexplate bolts. I would use ARP...
Looking at part's, I see the drive gear on the starter might be available as a seperate part? I would like to replace it with the new flywheel as a safety measure so they don't tear each other apart.
Looks like part number 12339360?
Anyone have the proecedure to replace the gear? It is...
No, I did not remove the starter or flywheel when I swapped the tranny. Starter bolts are solid. The starter looks like it was never disturbed, at least in the last decade!
It could be this started before I received the truck. I do recall hearing grinding briefly a couple times during the last...
Folks,
My luck just seems to be going from bad to worse. I am working two different AC problems in different threads and now another horrible issue developed.
When starting the engine I heard a horrble grinding sound while cranking. I get under the truck and pull the Torque Converter cover...
