stevo2551 Posted July 12, 2015 Share Posted July 12, 2015 Hi guys, I'm hoping someone can help me out, I've got an old yokomo gt4r and I'm trying to source 1st and 2nd gear pinions, and 1st and 2nd gear spurs. I've seen a couple of pinions from a gt4 but I would like more teeth. I believe part numbers beggining with ze- fit, but could anyone confirm this for me? and also I'm coming up blank on the spur gears, does anyone know of compatible pairs? any help would be apreaceated cheers Quote Link to comment Share on other sites More sharing options...
ta05 Posted July 23, 2015 Share Posted July 23, 2015 Your best bet would be ebay, sometimes a complete rolling chassis will appear if you're lucky. ZE616 is the first gear ZE619 is the second gear I did a google search and it looks like parts support is discontinued, rctech is a useful place to look around for info. Hope it helps somewhat. Team magic G4 might have some compatible parts, worth looking into if you have the time to. Quote Link to comment Share on other sites More sharing options...
ta05 Posted July 23, 2015 Share Posted July 23, 2015 ebay seller stanton-co are selling the ze616 if you need it. maybe they have the other one, I've not looked tbh. All the best Quote Link to comment Share on other sites More sharing options...
stevo2551 Posted July 25, 2015 Author Share Posted July 25, 2015 Thanks for the reply pal, I've managed to get a pair of 2 speed pinions and one spur gear from cml distribution, but the other spur I managed to purchase off eBay.fr, hopefully that will be here late next week. But it's been hard work sourcing the bits I needed. I've spent a fair few hours up to now completely stripping it down, cleaning and rebuilding it, and I can't wait to give it a test run once the last part turns up...

stevo2551 Posted August 4, 2015 Author Share Posted August 4, 2015 I managed to find the parts I need, only to discover the 2 speed clutch bell (ze-610) needs replacing :'( so after much more scouring the internet with no luck, I managed to buy a gt4 roller of a fellow member on here which should be here tomorrow. I didn't take many pics of the strip, clean and rebuild but I'll take a couple when she's all done and looking good. Quote Link to comment Share on other sites More sharing options...
ta05 Posted August 7, 2015 Share Posted August 7, 2015 It's never easy finding parts for older cars but I'm glad you've sorted it part numbers and ebay are sometimes the best way forward when you are searching. Quote Link to comment Share on other sites More sharing options...
stevo2551 Posted August 9, 2015 Author Share Posted August 9, 2015 I was able to get all the part numbers from cml distribution and then try my luck on fleabay with success in the end. I got a roller, which I got up and running, but had a binding coming from the rear I think, wasn't overly keen to leave the line without a nudge but once rolling its quick, when I let off in a streight line it veers off to either side. If I pick it up, all wheels spin as they should, but when all four wheels are on the ground it binds a little. I've swapped the .18 to the 'r' for now till I find the propper clutch bell for the novarossi .12r. But it still does the same. To get the engine to fit I had to swap the pully shafts over as I needed the longer ones for the belt to clear the pill start. checked all the bearings as I went and all fine, built back up and still does it but a bit less. I've had a good look over and stripped it back to the chassis and back again but still unsure of a remedy, I have the manual for it and the diffs are the correct way. It's like the diffs are fighting against each other or something... Quote Link to comment Share on other sites More sharing options...
stevo2551 Posted August 26, 2015 Author Share Posted August 26, 2015 (edited) Solved, or should I say greatly reduced the binding problem I was having, there wasn't/isn't quite enough adjustment for the rear brake mechanism to have enough free play through the throttle action. I think a slightly longer connecting rod might do the trick, but only one way to find out... a couple of pics of them both before I swapped the engines and layshafts over And a little bit of a stripdown... I'll add some more up to date pics when I next go in the man shed there doesn't seem to be many active owners out there on here or any other forums really which is a shame as it's a fantastic peice of kit Edited August 26, 2015 by stevo2551 Quote Link to comment Share on other sites More sharing options...
stevo2551 Posted September 2, 2015 Author Share Posted September 2, 2015 After a bit more tinkering and fettling I've managed to eradicate the binding problem altogether. Ran a couple more tanks through the 'r' the other day, not sure how to tune the rotary carb yet I'll have a look on good old Google next time I take it out. A couple more pics, not ran it with this shell on yet...don't want to scratch it haha Quote Link to comment Share on other sites More sharing options...
