Adamcurrie 34 Posted January 30, 2020 Hi, Picked up a vintage hotshot and wild Willy last week. Never had a Willy before. Just tearing it down at the moment to give it a clean and check. Can’t wait to get this thing going again. How do I remove the pin holding the wheel hex on? thanks Share this post Link to post Share on other sites
Rich h 1 Posted January 30, 2020 With a very small punch. But be carful not to brake the round alloy part Share this post Link to post Share on other sites

But be carful not to brake the round alloy part I'd advise soaking the pin (and the matching hole of course) in WD40 or a penetrating oil for a couple of days first. You really want to be super careful not to break the alloy part as they are extremely fragile. Just tap away at it with the punch gently - take your time - catchy catchy softly monkey Share this post Link to post Share on other sites
Adamcurrie 34 Posted January 30, 2020 Thanks! I’ll soak them for a good few hours and find something I can use to punch them out. Can I reuse the pins? Share this post Link to post Share on other sites
jonboy1 2943 Posted January 30, 2020 No probs You can indeed - although if you have some spare hex drive pins from pretty much any other rc car you can use these instead, which have the benefit of not needing to be pressed in (and therefore you don't run the risk of breaking the alloy parts reassembling them) Share this post Link to post Share on other sites

So be carefull removing the bearing, and as long as there is no need for it don't remove the potmetal parts from the alloy tubes. 1 Share this post Link to post Share on other sites

The ol' grey cells don't work quite as well as they used to! What I was mixing up in my head was that you want to be careful how you hold the assembly while you try and punch the pin out - if you clamp the bearing or the pot metal part it will probably break. Soak the bearing in penetrating oil before trying to remove it. Sorry chaps! 1 Share this post Link to post Share on other sites

I’ve cleaned everything and started reassembly to see what’s missing. I’ll be pulling it apart again to install ball bearings when they arrive. Technigold doesn’t fit but believe it or not, I don’t have a spare silver can! In the 2nd photo, the plastic spacers between the motor and top plate, I don’t have them so raised the parts to find a couple of plastics that looked right. Anyone got a pic of the proper part?

WillyChang 1814 Posted February 12, 2020 M38 really needs a vintage 540 with plastic endbell, there's a big ring that seats into the cradle at the other end. The only hopup motor that fits perfectly is the plastic endbell Black Motors. Then there's the pinion to consider - original is pressed onto shaft. 1 Share this post Link to post Share on other sites
Adamcurrie 34 Posted February 12, 2020 Ah yeah, missing the pinion :-( and the spare tyre on the back of the body Share this post Link to post Share on other sites

Adamcurrie 34 Posted August 31, 2022 It's been 2 years since I posted this. I shelved this and fixed the Hotshot. I should put up a post for that car. It ended up putting the technigold in the hotshot instead. I've been thinking about re-visiting the willy again 1 Share this post Link to post Share on other sites
