detaching the engine for clean...
 

i have the kyosho GS21 engine.
i successfully detached most of the parts out. but the flywheel part attached to the big shaft that drives the poston i could not take it out... it's way too tight to unscrew it...
is that part really necessary to take out for cleaning up the engine? or the dirt won't get over there?
or can i just spray wd40 anywhere all over to get the dirt inside to leak out?
thanks

we use a isopropanol alcohol (IPA) spray to clean our engines. (the same stuff for degreasing circuit boards etc....
turn the car upside down and over a sink. spray and maybe use a cotton bud for tight places. and now this is really important !!!!
leave the car to dry before starting it up. and when you do make sure you are outdoors
if you don't let it dry, you'll have a 40mph fireball on your hands ! :(
IPA dries without leaving any residue, doesn't rot rubber or plastic, in fact it "wets" rubber and it is a fairly powerful degreaser. makes your engine look like newshould cost about 5 quid from any PC store.

qiud? what is a quid?

A quid is a UK pound so about $1.60.

Bluefluffybunny is me and a friend.

Dont think that the car will catch fire!

thanks for the inputs all. :)
btw, can those electric motor cleaner spray works?
i think they are the same as those circuti board cleaners? (they smell the same...)
and after it dries out, i put wd40 to lubrificate right?

stop sniffing thinners! basically check the incrediants. IPA is IPA. dont worry too much but when you clean your engine make sure you block the in and out ports with stuffed tissue etc. you dont want chemicals in your engine.

I wouldn't use wd40, just use the ipa spray and leave it. wd40 is a solvent, with silicon in there. Silicon as we all know is inorganic. it actualy gets rid of dirt, but also drives out oil and anything else thats there, not sure what it does to rubber seals either. wd40 also leaves an awfull slimy greasy residue. this in turn will let dirt etc stay around easier. (like when you soill fuel on the chassis when running the car. Ipa is an organic solvent it does not attack anything and actually "wets" the rubber and keeps it supple/ rubbery, rather than drying it out. because ipa is 99.9% pure it leaves no residue. We however clean our full cars after every bash. (usually need to rebuild it anyway) the electric engine cleaner is essentialy ipa. may have other things in there. it should be ok though. ask you LHS. i just hate paying through the nose for stuff at our LHS. so find stuff else where. RS compnents and maplin are usually cheaper

what about denatured alcohol?

detaching the engine for clean...
 

dosnt clean that good

detaching the engine for clean...
 

denatured alcohal has half the degreasing power of IPA.
Acetonitrile has twice the degreasing power of ipa. Acetonitrile is a little too harsh, and may attack surfaces. Denatured alcohol isn't powerfull enough. I know IPA doesn't hurt your engine.

will IPA clean the rest of your truck? (or car) How much does it usually cost?

detaching the engine for clean...
 

Ipa or isoprpyl alcohol is fairly cheap. you can get it in a pump spray from your local PC / hardware store at around 5 GBP / 7 bucks, about 300ml (good for 3 -4 cleans)
We just spray the full car and then let it drip dry. also another good thing to use is compressed air and or muck off. motoer cycle cleaner. i like ipa as it dries without leaving a residue. spray it on use compressed air (available in a can) to blow of any dirt. and then drip dry. Please make sure it is dry before starting up you enigne. IPa also does not harm electrics.

so I can spray it all over my electronics, and it wont hurt a thing?

detaching the engine for clean...
 

IPA spray is fine on electronics. Basically we use what you buy from a pc shop. i think it is called isoclean something like that. just let it evaporate off. It is 99.9% isopropyl alcohol. nothink else in there.

i use break cleaner. that can be found at your local auto shop. its never hurt my electronics but i dont know if it could or not.

just so you all know, wd-40 is a degreaser, not a lube as so many of us have thought (including me) for a long time.

WD40
 

I don't like the residue it leaves behind though, it attracts too much dirt. I've tried Brake Cleaner before... evopaorates nicely, but does it dry out plastics?

detaching the engine for clean...
 

no it doesnt. wont hurt any thing. just to make sure i took it and sprayed over a crap servo. whol ecan. used the servo and it worked better than before.

Awesome! Brake Cleaner is cheap as hell too.. thanks!

detaching the engine for clean...
 

yes, alot sheaper than nitro car cleaner and other things

Wd 40 lubricates, but not in the traditional sense of the word.
It lubricates but also dries out items. it's hard to explain. I like old fashioned grease and oil, stays there and does it's job.
Simple experiment spray wd40 into some bearings of the bearings on your car, some nice expensive one's. give it 2 weeks and they'll be F'd. Then put some put some copper slip in the bearings you have had toreplace and they'll run and run. found this out in my skateboarding days, buggered bearings are not good !
wd40 drives out dirt, grease, oil etc...., but you are using oil in the fuel. therefore common sense says use something that does not leave a residue. using wd40 leaves a residue and arguements sake that gets into your engine, this then could effect the lubrication performance of your oil. i could be wrong and sometimes i am. just i wouldn't use it. Oh and if you get wd40 on a new body shell prior to painting it....... go get a new one.
