Water is the worst thing for idler pulleys, and any roller bearing for that matter. The balls or rollers get rusty and there is no real fix for them. A freed up water damaged idler will get noisy and loose in a short amount of run time. Sometimes, old dried grease can be flushed out with gas or WD as you mentioned. You should be able to push some grease in the bearing afterwards.

My BIL has a needle fitting for his grease gun, he just drills a small hole in the rubber around the bearing and fills it with grease. Seems to work good for him. He took a Simplicity tiller that had been sitting outside for 15 years and made the mule drive pulleys work like new.   Good luck.                                 Roger

I use a syringe filled with grease. Slip the needle under the lip of the seal and add the grease. A larger diameter needle makes it easier depress the plunger.

I use a syringe, too.  That way I can grease the bearing any time I need to.

Many idlers are held together with rivets. The bearings inside are often common ones and then you can bolt or possibly rivet the idler back together.

If its a common one, many idlers are available. Bolens1000 has a number of them, I'm sure SuperABen does too, probably most of our Sponsors would or could

I have pried the rubber seal off (with a jewelers screwdriver) and used carb cleaner to free the bearing up, add some grease and push the seal back on. Only works on the older ones that you can remove the seal.

For several yrs I've been carefully removing the crimp over the outer race w/ a burr bit in my die grinder, knock the old out and coat the bore and new brg w/ locktite. Haven't had one come loose yet.

Yep, most bearing sales stores will have them on the shelf. If you can't find the numbers take the old inner and outer races there and they'll find the replacement w/ inner and outer diameters.
