WR-02 Gearbox

[TexVan]

Years ago, I wanted to change the motor on my Wild Willy 2, but 2 of the screws holding the motor on are completely stripped.  I went to multiple hobby shops and they couldn't get them out.  I tried extractor screws...I feel like I tried everything, but I couldn't get those screws out -- I'm open to suggestions.  Ha ha.  And since I couldn't remove the screws, I couldn't take the gearbox apart either.

So recently, I decided I wanted to get the car running again, and I just want to get a new gearbox.  I've searched the net and can't find one.  I don't need the entire chassis, the wheels, or anything else...just the gearbox.  Is it possible to buy just the gearbox to a WR-02 chassis?

@TexVan Yep, you can buy the whole kaboodle with motor, parts number 18085153. 

Or the gearbox housing, TA-10005713.

Have you tried using a Dremel on the head of the screw? Just grind enough out so you can get a flat head screwdriver in there and extract it.

@JimBear Thanks!

 

@Gorgonzola  I don't own a Dremel tool, but it might be time to invest in one.  As for the stripped screws, its like a smooth concave divot.  There is little to no surface information for an extractor screw, or anything else to grab onto at this point.  I've never encountered a screw this stubborn.

Just buy a cheaper one buddy. I bought one of Ebay for 30 quid and it's superb. It lasted way longer than a genuine dremel. You might have to drill into what's left of the screw and try extracting it that way. Are they hex head screws?

@Gorgonzola  It's just a regular phillips head screw.

The drill and extract method might be your best option. There's bound to be some videos on YouTube showing how to do it.

Given the fact you can buy a replacement gearbox for about £30 I don't think it's worth the bother of Dremels etc if you don't already have one!

I'd just buy a new 'box, then hack the old one's casing about to salvage a few spare parts for the future.

@Twinfan  Yeah, I don't think I'm going to run out and buy a Dremel set right away, but it is a versatile tool, and I have run into a few situations where having one would be handy.  For now, I may just order a new gearbox.  A Dremel would probably help cracking open the old one though.  Ha ha

Just drill the screw heads off and yank the motor out. Simple job, don't waste a whole gearbox.

3mm screws only need a 3mm drill bit if you can centre it.  Might avoid the plastic completely with a steady hand.

[TexVan]

Like I said, I've tried drilling them out, several hobby shops have tried getting them out, I've tried extractors...they are really stuck in there.

@MadAnt Here's what it looks like.

Drill it until the heads break off.

I have no clue how you messed this up unless you used the wrong type of driver or tools.

How do the rest of the gearbox screws look?

Ha ha ha, I don't either.  The rest of the screws are perfectly fine.

That is impressive. I don’t think I’ve ever seen that before. There must be thread lock involved because over tightening surely would have cracked the gearbox.
