Grease for polisher

[JustJesus]

JustJesus- Huh, that *did* look really nasty in there! Guess it`s a good thing you opened it up and regreased it.

My mistake for not making it clear. Only that one bit looked nasty. The "clean" grease is from the factory. I hadn`t regreased it yet.

Last night, I finished taking it apart. I kind of regret it now! Removing so much of that good grease, only to apply more good grease?

Okay okay. In all fairness to myself, I figured I`ll try out the process on my cheapest polisher, the PC, before attempting to do it on my Flex 3401.
That, and since I started, I kind of wanted to finish

Tonight, if all goes according to plan, I`ll add the new grease. The parts were cleaned last nigh, and just awaiting the new stuff.

Wish me luck

Why are you regreasing your Flex 3401? All I`ve ever done to mine is the rare (maybe three times total) reoiling of that felt-like ring behind the plate.

it`s for the used model I bought, my second 3401.

It`s an early model, I want to say 2009 or so, and I bought it off ebay. On one of my last jobs, I was using that one more than my newer 3401, and I was noticing my pads getting some heat warp type stuff. I swapped the BP on both 3401s, and noticed the old unit had a bit of "darkening / burn" type stuff, sort of like when you check the dipstick on a car that ran with too low on oil? if that makes sense.

Also, I`m sort of going to "modify" some bits, and figure might as well replace the grease (and any wear items as needed).
(don`t ask about the mods, it`s a secret for now..hehe)

I do tend to reoil the felt ring almost every time before use. It`s quick, and I figure cheap insurance. How else will I go through that hole bottle of the oil, anyhow?

I figure in any instance, no matter what machine, and what grease, grease gets old, it liquifies with generated heat, and then from centrifugal force gets slung out of the way from where it`s needed.

That periodic inspection, and re-greasing, provided re-assembly is done properly with no damage, any and all units will benefit, and then live a longer life.

Ah, OK..does sound like it could use some attention.

Yikes, it makes sense but I`m glad I`ve never experienced anything like that!

Ah, you`re young...you`ll use it up. Though I bought that tiny bottle of SnakeOil back in the `90s, used it a *LOT* at the range, and still have most of it left.

Gee, I`ve maybe lubed that felt ring three-four times since my Flex was new...you must lean on it more than I do as there`s hardly ever been any contact to justify the oiling. Guess I`m careful after all the (IMO user-error-related) failures when they first came out (mine is a really early one).

I figure in any instance, no matter what machine...

I sure won`t argue with that Guess I`m spoiled by those Cyclos....*Zero* maintenance for decades, including years of frequent use in a shop, and when I sent the oldest one in they said it didn`t need *anything* at all.."it`s like new inside"..though I did have them chance the brushes anyhow. Note that unit had been, uhm...abused badly..too, was even left outside during some storms.

I buttoned her up last night. The regret I had, was gone after I was done. I`m glad I did it.

What`s the best way to get that gear assembly out of the top there? Does it just pull straight up and out once you get the plate cover off? Mine was on there good I figured I was missing something, I ended up power cleaning and repacking the new grease from the sides.

Looks good!

 

[JustJesus]

Loach, thanks.

You are correct. There is another two steps before you can pull that gear off. On the other side, you will need to pull the bearing assembly out. It`s the part where the backing plate screws onto.

That exposes a small 5/16" bolt head that needs to be removed. Remove it. You will need to hold the gear assembly as you unbolt it. I used a flathead as a pry bar against the gear, as accessed through the hole on the other side.

Once that`s off, the gear assembly pulls straight out.
