Posted: Fri May 13, 2005 5:39 pm Post subject: Generator Mounting??
Is this suspose to be such a tight fit?
I can't see how I am suspose to get the generators 7 1/4" inside measurement of the mounting plates on to the 7 1/2" overall measurement mount with the rubber bushings.
Can the generator be stuffed into that mounting space?
And assuming that I have the right mounting bolts now with the 7/17" threads.

The 7 1/2 " measurement is not right, the distance between the back of the motor mount plate to front of the L bracket ,(not the round part) should be about 5 5/8 ". Let me know if you need more measurements.
Ken,
Looks like you have too much meat sticking out front on the engine mount plate. Take the rear bolt and bushing out and slip the generator in place so it's front leg is pressing tightly against the front engine mount plate. How do your pulleys line up? If the generator pulley is still too far forward of the water pump and crank pulleys then that steel bushing welded in the front plate is too long. _________________ Wes K

The thickness of the front mount bushing alone (with out the rubbers) is .840"
I will mount the generator without the rear rubber bushings in place to see if all pullys line up, and get back to you later.
It looked like I could have squeeze the generator in place if I was to remove a rubber bushing on the rear end. _________________ Tropical Veteran

The front plate isn't bent. I was able to get the generator on the mount by leaving off a rubber bushing on the rear bracket. I posted some photos on http://photos.yahoo.com/kls235
they seem to be too dark on mypic gallery. I had my grandson hold a straight edge on the crank pully to the generator pully. They almost line up. It is a little cockeyed because the rear bolt is too long and I had to leave out the rubber bushing too.
Are the bolts suspose to be identical?
And it appears that the bracket that bolts to the engine is alittle too long also. It is about 6" from the inside of the "L" to the engine plate. _________________ Tropical Veteran

TM 9-8012, Page 195, Figure 66 shows the correct mounting hardware for the generator.
SNL Page 119 lists The following hardware:
2 ea - INSULATOR, ru, 334 ID, 1 1/6 OD, 1 5/32 thk (mounting support)
2 ea - BOLT, SHOULDER, hex-hd, S, 7/16 X20NF-3 x 2
2 ea - NUT, PLAIN, HEXAGON, It, s-fin, S, cd or zn-pltd, 7/16X20NF-2 (supersedes NUT, HlOl-0218585)
2 ea - NUT, PLAIN, HEXAGON, s-fin, S, cd or zn-pltd, 7/16X20NF-2 (superseded by NUT, 120370)
2 ea - WASHER, FLAT, It series, S, cd or zn-pltd, 7/16 in, 15/32 ID, 59/64 OD, 0.065 thk
2 ea - WASHER, FLAT, S, cd or zn-pltd, 17/32 ID, 1 1/16 OD, 0.095 thk
2 ea - WASHER, LOCK, It, S, cd or zn-pltd, 7/16 in (superseded by WASHER, 136857)
2 ea - WASHER, LOCK, S, cd or zn-pltd, Style No. 1, 0.740
in OD, 7/16 in bolt size (supersedes WASHER, 121621)
There should be a flat washer on both sides of the rubber bushing, the generator pivot tabs, a lock washer and finally a nut.
Thanks Hal, I don't have the TM 9-8012 with a picture. Do have a parts lists. I really must have the wrong bracket that mounts to the engine because I couldn't get the Gen. mounted without removing a rubber bushing. So If there are flat washers that go on each of the the rubber bushings, then there isn't anyway that I have the right part. _________________ Tropical Veteran

Thank you so much Wes. A picture tells it all. I had some manuals on CD but that TM9-8012 wasn't in it. I have one coming now. I hope the repo maunal has good pictures.
After seeing the yours and Hals post of the picture and the detailed parts list, I am still a bit puzzled on how one rubber bushing on the front and one on the rear mount is sufficient for providing the support.
When I ordered my bushings, they sent me four. So now I was thinking that all four had to be used. But not so, accordinging to the parts list and picture.
In the picture you posted, the letter "N" is pointing to something I can't make out, and you didn't list it. So maybe it is insignificant. _________________ Tropical Veteran

In Wes' picture the "N" is the engine front plate...
You have a set of the newer bushings, the originals were solid one piece and went thru so that they had shoulders on both sides of the mount... you should still place both arts of your bushings on. I know it is a tight fit but patience pays off.
As DJ said in his post, "the distance between the back of the motor mount plate to front of the L bracket ,(not the round part) should be about 5 5/8 inches ".
I measured mine when bolted to the motor block and I come up with 6 1/8". With bracket in my hand I get 6 1/16".
So that makes it too long, and is why I can't mount the Generator.
What a fiasco!! _________________ Tropical Veteran
