Cleaning Inside Of Crankshaft

[James_03]

Hey guys,

For those of you who have done it, what's the best way to go about cleaning the inside of a grub screwed crank?

Apparently you can get wire brush cleaners that you can bend to get inside?

Cheers.

ive been told good old fashioned pipe cleaners work well...the proper cotton cloth ones, not those silly sparkley ones they sell at craft stores.

Rifle barrel brushes. Not sure if thats the proper term.

They look like twined fencing wire and the end has plastic strands wound in with it and you twirl them in and out of holes with your choice of cleaning product/solvent. Thats what the ones I have look like, no doubt there are a variety of similiar looking products which will do the job just as good.

Can of carby cleaner, thin stiff pipe brush, air compressor and blower. Take grubs out, pump the carby cleaner in, brush as much as you can then blow out any loose bits and repeat until carby cleaner is coming out clear then do it one more time to be sure.

Spraygun cleaning kit and thinners is the best I've used.

Yeah I ended up getting a "moroso engine block cleaning kit" from repco. Had to order it in.

I was told by a couple of guys that the spray gun cleaning kit works great too as you mention r31. Now just need some carby cleaner and Im set, got a HD air compressor off a mate too blow it all out at the end.

Thanks guys.

i usually remove the grub screws, use my hot tank at work and replace with new grub screws

[T04GTR]

what is the solution used in the "hot tank" also the cold tank? trying to buy some for work, but cant find out what they are called...

[Sammy]

Hot-tank is just a strong caustic solution. Pure caustic powder/soda can be bought at your local supermarket.

Cold-tank i'm unsure of, but can't be caustic because it would turn alloy into a lovely poisonous gas/sludge. I'd say it would be a solvent of some variety that's fairly PH neutral, like degreasers in a can.

[T04GTR]

yeah i know the hot tank stuff, but the cold tank i thought was a solvent de-carboniser solution, till i put my hand in it and the next week i lost all the skin off it. after i turned yellow that is... you put water in it to stop it evaporating and keep the smell down.

For brushes, go to a laboratory supply company and get Test Tube Brushes. Got 5 brushes from 3mm to 20mm for $15
