hpop drive gear

[melmount]

On the gear that goes thru the reservoir and timing cover, the gear that attaches to the hpop with the 18mm bolt and washer. Does that skide straight on or does it line up with some kind of key way?I am assuming just goes right on.
thx

It is completely smooth. It holds on only with that bolt and washer. That is why it is important to get it *real* snug. I use a 3/8" impact with a shallow 18mm socket. Even on my vans, I have just enough room to get it in there with the fan in place to remove or install it. A truck should be easier, since the fan clutch and fan sit about an inch farther out from the engine.

Yes it is smooth, no key way.

cool, I hope I got it tight enough. I used a long ratchet handle 1/2 drive and once it got tight i banged on the end with my hand as hard as I could. The quick force prevented the gears from turning(sort of) I did it like 10 times. I removed it by banging on the handle once. It was not that hard. Hope its good enough. It runs better now,

I am sure you would have seen a problem if it wasn't tight enough.

[melmount]

i hope so. Its not looser then it was. That i know. If i hear any loud noises or something i will pay attention. It should be good

[elibenson]

If it comes loose, no big deal. Your truck will shut off immediately though. The bolt can't back out enough to fall down into the engine or anything. More than that, if it came loose enough to shut the engine off, it certainly wouldn't be backed out far enough to fall out completely because the engine will quit before it does.
