Quick OWB Clean

[ajames942]

Hey guys as some of you know the t-maxx is running great. BUT the OWB is slipping and i dont really have the time to take it apart and clean it because i only have less then an hour and a half to run it when it snows tomorrow hopefully. I was wondering if theres anything i can do to clean it quick without taking it apart. Thanks Guys!

Some say WD-40 down the head. I don't think it is a good idea (we have had arguments about it here before). You could try a little carb cleaner. Just a puff then spin the motor over. Nothing beats removing it though...

WD-40 I don't think ever works to un-slick a owb. I dont think there is much other than carb cleaner for a quick, yet maybe ineffective, fix.

If you need to start it before you run tomorrow, Take a hair dryer and heat up the back as much as possible. Should make it grip pretty good. But you would have to do this every time untill you actually cleaned it.

Wish we had snow here in tacoma Washington.

Yeah, its only bad getting it started when its cold, when I'm out running it and it stalls, it starts up right away no problems. Its about 50 degrees in my garage when i start it.

So just heat it up before you run and you should be good. Just don't let your mom catch you.

Look at the bright side, it's suppose dto snow this weekend.

Nice to see someone else up in my neck of the woods posting on RCNT.

Well, squirting anything down the glow plug or in the carb on a traxxas engine is pointless. The OWB isn't inside the engine.

You can drill a small hole in the center of the starter case, then a small hole on the bottom of the starter case as a drain. A quick shot of WD-40 works just fine. Pull the starter a few times, then blow compressed/canned air in the hole to blow the residue out the bottom of the case through the drain hole you made. Makes a bit of a mess... but you gots to do what you gots to do!

I've done this with OS engines time and time again. However, I started using DA vs WD-40, then I'd put a few drops of 3-in-1 oil to lube the bearing back up. Just make sure to point the rear of the engine up before spraying WD-40 or DA and the oil, so gravity will take some of the DA and oil down onto the back of the bearing and starter shaft. Less of a mess using the DA.

I thought heat makes metal expand =/. Won't that make the OWB expand? I'm just guessing.


Anyways, what I did for my OWB is I sprayed WD40 on it and it didn't slip anymore.

A lot of times (especially when cold), it's oil gum that makes the OWB bearings/springs stick, so the bearings don't come out properly and connect with the shaft. Heating the engine up makes the gum softer so the bearings can move to where they are supposed to.

This of course is less likely of a problem if you maintain your OWB periodically.

There is about 5 tanks left on my first gallon in this mill. Everything was new when i got the engine so i will clean it when this gallon is done.

I just squirt a shot of brake cleaner down the hole for the string when it gets temperamental... works every time

I've never had problems with melting plastic or anything, so it should be safe.

I have the E-Z start. I have a pull start that came with my engine, so I'm thinking about ditching it and put the pull start on.

 

[Skwerly]

Once I can get mine to start up faster, I'm going back to the pull-start, as well. Charging the batteries and all that is becoming a pain - not to mention the extra weight of the starter engine and all that hehe. I like stuff that is simple, yet effective.

Here is a dumb question. Where can you get "DA" from?

 

[Tmaxx96]

i put it in a little glass container of fuel and shake it

Hardware store in the paint supplies isle. You will find mineral spirits and other things there in tin-cans. Denatured Alcohol should be there too.

When you DO take the backplate off, massage the starter shaft with some 1000 grit wet and dry sand paper and rub the starter shaft from the front end to the rear end, not side to side as it won't work as well.. It creates a key for the OWB to grip to and helps no end. I do it with all my stock engines with a pull start. It hasn't failed me yet.

DA ?? Try Humbrol Enamel paint thinners. Works even better. (model / hobby shops). Even beats carb cleaner.
