So what is the smallest size for the better made CRB's ? Smallest Pro Version I guess. I don't see how I could use a 10 inch now that I know it will fall apart if I'm not super careful...

This was a situation where extensive metal corrosion resulted in bearing failure
The gears were not at issue, it was the bearings on the lower gears that drive the brushes that had seized and could not be extracted from the side plate.
So can a silicone or rubber gasket be applied to keep out those pesky
oh good lord...
Gear box..

While not sealed I just can't see pre spray getting in there unless a careless tech used a HF to wash it down at the end of the job/day

Only open areas I can see where possible splashing could get in but all the guts and motor are up high, so again, the corrosive liquid would have to be sprayed in there, while the machine was upside down..
Arrows pointing to areas where liquids could get in.. But not during cleaning...

So I applied this stuff to the two areas that COULD potentially cause an issue, if you were using the tool to scrub walls or ceilings..

Reg and or Steve can you point out were you saw the corrosion?
Spray these areas with WD40 or it's equivalent every time you put the brush rolls back in
Saiger and I have both experienced the nightmare of having the axle rod get stuck in the receiving end..

Are the bearings not sealed bearings?!
Heck of a thread you started here Rick...
I know a lot of motorcyclists who use WD as chain lube..
I'm pretty sure the bearing is replaceable.So that bearing is not replaceable?

So Dan,
Thank you a ton, I have never heard the Wedge lube theory---absolutely awesome.
Mikey, Motorcycle vs Bicycle chain lube is exactly as Dan said. The lube for motorcycles is much thicker to stay on the chain at higher speed and to have a thicker Wedge.
I would only use WD on a bicycle or motorcycle chain I was about to replace to get rid of the squeak so I could ride it back to the shop.
WD displaces water AND the lube that is already there.
Dirt motorcyclists seem to be the most common users of WD on their bike chain as a lot of them use WD to clean the outside of their dirty bikes. ---horrible to use WD on a bike chain.
Chain technology has been focused on in the bicycle industry because we are working with 1/20 th of a horsepower and trying to go as fast as possible with tiny energy input.
The chain is far and away THE most efficient method of transferring energy. But they wear themselves and the gears they run on rapidly. The stretch is easy to measure in a bicycle chain and once the chain stretches a little bit they wear the gears rapidly. Especially small gears--the smaller ones in back and the smaller ones up front.
Motorcyclists get away with bad chain care because energy loss is not a problem, you are not moving the chain from cog to cog regularly like on a bike.
I know this is too long a post for Bama Hogwarts to read..
So it was just the brush roll axle bearings that failed on Steve's unit?
I wish you and he would have told me that.
There aint diddly one can do about getting pre spray in there..
I wonder how The Little Ivan is set up in that area... Might need Zerks..
I got 34k out if a chain and rear sprocket on a road bike
Re applied every 400 miles or so
glad you added the lolUse a 175 with a brush or red pad....
lol
