Newbie Qn: How to clean and maintain the Nitro Engine?

[Richard]

Hi,

I am using a OS .15CV engine, the one with the blue heatsink..
Since I bought 2nd hand and the previous owner has nv open the engine for servicing b4.. The glow plug and heatsink is very filthy with dirt... I want to clean it..

1. Shall I open it up for servicing? Or someone with experience can show me?
2. What is used to clean the engine innards?
3. What things to watch out for?

i strip my engine bear for my r/c cars and soak then in thinner... but remember to take care of rubber seals as they get corroded and it'll be useless...

after that assemble and lube with wd-40 once engine is back in a piece remove glow plug spray just a little of wd-40 into the chamber at a time until u're more or less happy... crank the engine everytime u spray by turning the flywheel

before u start i advise u to standby the blueprint of the engine. unless u know it inside out

[sinner]

if u like i can show u how to when i'm free =) just need to get a bottle of good quality thinner (try not to get those in glass bottle) just personal preference

what u'll need is:

1. a glass or metal container (to pour thinner and soak)
2. tissue, cotton buds
3. basic tools

pour some into the container after u've stripped the parts. pour alittle at a time as it evaporates quickly. standy tissue and cotton buds, use cotton buds to rub away sign of rust (if any) and tissue to dry them.

ensure that u've something to hold all unclean and cleaned parts as they're small and are often misplaced. now the only area i'm not going to advise u cleaning is the throttle body. as for the reset u may strip it bare cleaning piston etc.

word of advise, NEVER NEVER get the rubber seals/ gasket in contact with thinner. if u need to use a mildly damp bud to clean (repeat process if required).

'Regards
Sinner

I won't recommend striping and cleaning the engine on your own. Esp removing the carb. But if you must, during reinstallation use "after run oil".

Hi,

I download the blue print of the engine.. seems alot of small parts.. Yesterday night I tried to remove the top four screws from the haetsink.. its so tight.. almost broke my wrench.

already mentioned in my post that the throttle body (carbrator) should not be touched

Can remove the heatsink and backplate. Flush with nitro. That would be enough.
Unless you want to remove the piston, sleeve, con rod, crankshaft and bearings

Messing with the carb is fine, if you know how to tune it back. If not, it would lead to many many frustration moment

Upon assembling, use some gasket sealent to seal off all possible air leak

For external, just blast it clean with contact cleaner ... expensive but it works I usually brush the bust off with a brush and its ready for the next session

That are lots of writeup on the net that leads you to clean the engine... can do a search at www.rccaraction.com

Good luck

Good Idea!!

Den can put it as sticky.. Anyway, the heatsink is super tight.. couldn't remove it..
Den I found my pull start supposed to tighten by 4 screws to the engine, now left one.. where to buy replacement? I dun really like to go hobby shop, buy some screws can cost 5 to 6 dollars. Really felt screwed

Try to invest on a good set of hex drivers, which have hardened steel tips. This will help to minimise the chance of stripping a capscrew. Do not use the cheap L-shaped allen keys. If you ever stripped one of the heatsink screws, you're a goner.

Use the correct tool for the job!
