Ill look at the pictures and see what I can scounge up.

Want what you paid for it, back?

The teeth are PAPER THIN and knife-edged. It damnear cut me taking it off the shaft.

Nah, I'd rather get a gear at the same great price. ;)

What grease goes in there? For now, I gooped it with some white lithium grease which I had handy.

When I took my xmission cover off, the oil was *gold* from the bronze wearing off over time. It originally comes w/ oil, gear oil I would imagine. I put a gear oil in there, w/ some Kroil, Marvel Mystery, spit, whatever. I filled it up much more than the original, for good immersion. If you *really packed it* w/ white lithium, I dunno, should be oK. I would put in some gear oil anyway. I've noticed, that until the greases gets hot, the gears may turn in a kind of cavity, and not get really wet. I'd prefer to pack in Li grease or sumpn myself, but always wondered about the intimate contact/immersion of everything.

The instructions on my HF 4x6 called for 90 weight hypoid oil, used rear-end lube from Autozone when I cleaned out the gear box(not a whole lot in there to clean out).

My dad's 4x6 did the same self-destruct thing on the worm, we managed to get a new gear set out of the dealer for free. Worm and wheel should BOTH be replaced or it'll do the same thing again. Changed from a bronze worm and steel wheel to the reverse. Seemed to work, the originals destructed in only a few cuts, the replacements are still going 20 years later. Sticking a magnetron magnet on the gearbox cover will grab the steel particles, does nothing for the bronze, though, also gives you a place to stick wrenches for the adjustments.

ach!

Its supposed to be gear oil.

Interesting. The gears in mine still look great, but I had started running it before I had encountered the "drain and clean out the gearbox of casting sand" advice, so earlier this year it got to the point where I couldn't get it track worth beans anymore, and found the bearings were toast. Found bearings on ebay, but had to dig for a while to find the bearing seal, which I eventually found at MSC. Replaced all the blade guide bearings while I was at it, the ones on the lower side where all the chips end up were also toast, the uppers weren't much better. Blade tracks well and the saw cuts square once again.

As for the gear, I regularly see them mounted on a shaft listed in ebay stores for a not unreasonable amount. --Glenn Lyford

Egad, not the dreaded Skunky Hypoid Elixir of Death!?! I thought I was done with that crap when I left the automotive field in '86. Come to think of it, the crud in the gearbox case did reek of that...

Great! Danke Mucho for the tips.

What's a magnetron magnet, and where do I get one? Excellent idea. Might, however, be more effective put the magnet on the *inside* of the transmission.

Most of mine came from the local electronics surplus store for cheap, now no longer in business. Every dead microwave oven has two donuts, be careful with the HV caps on disassembly. Also used with a newspaper bag for picking up chips, maggie in the baggie, turn inside out when there's enough chips collected, peel off and dispose.

There's not a lot of room in that cavity for one thing, for another, it's hard wiping shavings off a magnet directly(see maggie in the baggie above). A magnetron magnet has intense enough flux to penetrate the cover, anyway. Works with rear end covers, too, assuming they're steel.

Excellent tips. Elegant idea! Actually remember sumpn from long ago, bout magnets in an engine sump-- Ooooh, OOooohh, OOOOHHHHH---

I GOT IT, I GOT IT!!!!!!! JC Whitney sold, at one time, magnetic drain plugs fer cars!!! Great idear, never thought to extrapohlate it to other scenarios. Magnet in a car transmission couldn't hurt either, I would imagine.

Now, iffin I could only remember d'wife's birthday....

Yep such a good idea that just about every auto now has a magnetic drain plug and a magnet in the transmission pan as well.

On the B'Day, it was the day BEFORE she smacked you up beside the head and asked you how you liked sleeping on the couch......

She must have a birthday about once a month, then.

I betcha the drain plugs on my mazda 929 and Nissan frontier don't got a magnet--no magnetic tip like on one I saw a long time ago. Unless the whole goddamm thing is magnetized..... Hope so... :)
