As the heading says im starting to build a 1/4 scale MT i have been colecting parts for a few months now and i think i have enuff to make a start ...

heres the engine 39cc water cooled pocket bike engine comes complete with every thing needed to run and puts out 5kw standard ;D


and heres what im using for front and rear axles they are off a self driven toro mower









tyres are 10x4.5-5" front wet gokart race tyres


alloy rims and fitted up the tyres on them heres a pic


been playing with the unis that my bro found in oz for me the are socket set unis but they are a ball and pin set up .......

they will do for the steering front axle but i think they will have to much slop in them to use as drive shafts they will vibrate way to much i think will look at maybe trying to shim then or something to take up the slop any way heres some pics





heres 2 photos of the front axle





finished both front axles with uni joints


started on the front hubs and drive flange will weld lugs on the the hub where needed

da mad maori

good to see ya build on here Bentley!!

as for scale? get some pics measure, and scale em down

Very nice parts!Good luck with the project!I wanted to begin one too,but if i do i'll never get my boat!Anyways,Bentley what are you gonna use for shocks?Also,how much did that engine set you back?

bentley marshall

im not sure what imgoing to use as shocks yet i need to build all the chassis etc so i know how long they have to be then i will go hunting for some thing to fit
the engine cost me NZ$300 (US$176)

Lars from Norway

Looking very much forward to see more of this project

Nice.. I like the water cooled engine!
What are you planning to use for a transfer case, body?
Running solid axle in rear or 4 wheel independant suspension?
Might look into LST shocks, there huge, capable of stabalizing heavy chassis's, offer about 3" of shock travel, and there rather inexpensive. You can usually pick up 4 prebuilt shocks off e-bay for about $40.00. If needed you could double 'em up... With some thoughtful placement ie canterlevering, they could offer 5-6" of suspension travel if the Uni's are as capable...
I spotted these 5th scale Baja shocks the other day in another forum, not sure if there any longer than the LST shocks though. The consensus is there top shelf, tuneable, but they aint cheap, @ $180.00 for a set of 4 before any changes/upgrades.

hi yeah i like the water gooled engine to and thye put out a lot more hp than a 50cc air cooled

the transfer case i will make will only be one speed and no reverse will be tooth belt or chain driven and have a disc brake on it as well

will be running fixed axles font and rear and only front wheels will be steering

as for shocks i realy need to get the the whole thing built so i can see how long and how strong they need to be i have been looking at some pocket bike shocks that might do the job with differnt springs ..

bentley marshall

well made some more bits made for the truck today .....front diff is geting closer to being finished

Mmmm gonna be a big one for sure!
Am looking forward to more pics as well.

Hey that axle from the Toro lawnmower, that would be from a ride-on lawnmower, no?
Good idea.
Been thinking about how I can get hold of something like that.

trophyMCfly

can you please tell me where I can get that motor for under 200 bucks

mcspanners

Wow thats gonna huge! great work Bentley, i hope this one doesn't run away on ya[X(]

Looks awesome. I'm thinking of making a 1/4 scale rally car (or 1/3 scale) as a summer project. Not sure if my dad up to helping/paying for most of it though. I'll definitely be watching this build.

bentley marshall

hi no the axle is out off a push type mower not a rideon

bentley marshall

the motor was bought from a shop here in New Zealand try lookin round ebay

bentley marshall

yeah mark will be running a kill switch on this for sure

mcspanners

Hi Bentley,
First off, CONGRATS. Thats great news. You take your time and take care of your baby.

Were are you getting the ballends from? I'll have to look around, I had a place that carried everything.

Hmmm, I believe its 1/2" and aarrrgggg I cant remember, I will get the size of the tubing tomorrow for yah.
Sorry about that. I've been putting my truck off for a long time, actually since I have had my baby .
Keep up the great work.
Later man
