Josh's Y-Town Crawlers "Villain" Shaftsmen Build
 

Decided it was time i started this build thread.

First off to a big thanks to Krawlfreak for pushing the bar higher with the YTC line of chassis' "thumbsup"

So to start off this build i ordered up a couple of AR60 housings with intentions of shortening them.

http://i1179.photobucket.com/albums/...521_180733.jpg
A set of plumbers/fridgey tube cutters made short work of the plastic housings. 19mm (3/4 inch) was removed from the long side tube.
http://i1179.photobucket.com/albums/...521_181529.jpg
Next cut a piece of 9mm thin walled brass tube to length, to be slid into the axle to reattach the longside tube
http://i1179.photobucket.com/albums/...521_190726.jpg
The sleeve is inserted into the housing with C.A glue/epoxy then the longside slid back into position.( I should mention i marked a line before cutting to make realigning easier)

Next was time to add the usual VP steering parts aswell as some VP vvds, now that the longside tube was 19mm shorter than standard obviously these wouldnt be a straight fit, so axle housings, steering components and VVD's where dropped off with Dan @ Hulksta Engineering to have him work some magic.

Here you can see the standard axle in the shortened housing

in this pic you can see the axle is shortened and a new tang milled onto it.

The internals on the axles will be gripfab spools and the usual over/under gearing. Dan is making a custom set of 5mm Ti axles to suit these housings.

So next was time to build the transmission.

After reading a few threads it was decided a HR gearset would be used.

I ordered up a set of long 4340 5mm Crawler Innovations lightweight outputs
http://i1179.photobucket.com/albums/...712_215507.jpg
I bolted them upto the final drive gear, marked it then set my dremel onto it, here is the outcome.

With the outputs bolted up

Once again i did the insert mod on the mounting holes of the transmisson
http://i1179.photobucket.com/albums/...713_174252.jpg
For the idler shaft and slipper elimination shaft i picked up a set of Ti shafts from RCP and an axial transmission kit with the plastic spur carrier
http://i1179.photobucket.com/albums/...709_185239.jpg
On this build i will be running 32p spur and pinion
http://i1179.photobucket.com/albums/...709_185444.jpg

Now onto the chassis

My kit showed up Tuesday and i dove straight into it
http://i1179.photobucket.com/albums/...722_182106.jpg
http://i1179.photobucket.com/albums/...722_194054.jpg
Every piece of this kit is excellent quality and fits precisely.

I got the chassis together and ready for my axles to return

Thats all for now.

Thanks 8)

So next on the list was the shocks.

This chassis is designed to use shocks ranging from 3 to 3.5 inches.
I decided to shorten my Alumnium SCX shocks 10mm total 5mm from the shock body and 5mm from the shaft.

Here is the body chucked on the lathe ready for shortening
http://i1179.photobucket.com/albums/...727_100830.jpg
This is a comparison of the shortened body and a standard body
http://i1179.photobucket.com/albums/...727_100919.jpg
With the shock rebuild i ordered up a set of the Axial machined pistons to use on this build.
Machined piston and shortened shock shaft compared to standard shaft and piston
http://i1179.photobucket.com/albums/...729_170659.jpg
The finished shock measured in at 3 1/8" or 79mm eye to eye.
http://i1179.photobucket.com/albums/...729_192745.jpg

I have set these shocks up with 35w oil and will be using Losi Mini T Silver springs, also have done the bladder mod on the shock caps.

Thats all for now.

Looking really good Josh, how long until you think this one will be a roller?

Re: Josh's Y-Town Crawlers "Villain" Shaftsmen Build
 

Thanks"thumbsup", I am hoping to have it rolling by the end of August but that will be dependant on when Hulksta finishes up the TI axles for the rear.

So tonight I finished up the transmission and fitted an unused HH motor just for mock up.

The longer bolts I had been waiting on showed up today and I was able to get the YTC motor plate mounted up.
http://i1179.photobucket.com/albums/...730_195922.jpg
You can see it is designed for a smaller diameter motor can
http://i1179.photobucket.com/albums/...730_195939.jpg
And the complete trans lubed and ready for install into the chassis
http://i1179.photobucket.com/albums/...730_200002.jpg
I will be running 32 pitch gearing in 60/9 with a BROOD 30T powerplant to supply the torque.

Fitted up the trans to the chassis
http://i1179.photobucket.com/albums/...730_200659.jpg
http://i1179.photobucket.com/albums/...730_200724.jpg
This picture shows the transmission mounted and sitting in front of the chassis centre line adding to forward weight bias.
http://i1179.photobucket.com/albums/...730_200803.jpg
And finally the gap between chassis rail and spur is more than enough clearance for my liking.

Rob over at SMW did a fantastic job on these skids, no slop and awesome tolerances and finishes all round8)

Nice work man. I like it

Re: Josh's Y-Town Crawlers "Villain" Shaftsmen Build
 

this thing looks awesome!

hope it is everything you expected and more"thumbsup"

Re: Josh's Y-Town Crawlers "Villain" Shaftsmen Build
 

I'm not familiar with the wraith axles and what they measure stock. What's the purpose of cutting down the long side tube?
I understand centering the pumpkin would have driveshaft clearance advantages, but what about staying full legal width for stability? (stupid question if shortening it actually makes it legal width)

Otherwise I love the idea of having access to your internals without having to take apart the whole freaking axle. Very cool.

Re: Josh's Y-Town Crawlers "Villain" Shaftsmen Build
 

Thanks8) So far it has been above expectations and once i get it driving im imagining it will be the same.
Great design work as always"thumbsup"
The villian link plates are designed for an ax10 axle or narrowed ar60(wraith) i chose the ar60 housing as the diff pumpkin is offset keeping it closer to the wheel and hopefully keeping it away from the diff catcher rocks that i get hooked on with my current ax diffs.
i believe the ar60 housing is legal for 2.2s in standard form."thumbsup"

Re: Josh's Y-Town Crawlers "Villain" Shaftsmen Build
 

There is no legal width to speak of. But the minimum gates distance is 14", so the wider you goes, the less lines you can use to tackle a gate. A shorten AR60 will allow more options (compared to full width) in tackling a gate and also being wide enough to improve lateral stability.

As Joshie said, an offset pumpkin will minimise rock hung up and also lower servo placement.

Re: Josh's Y-Town Crawlers "Villain" Shaftsmen Build
 

16" "thumbsup"

Re: Josh's Y-Town Crawlers "Villain" Shaftsmen Build
 

Yes there is, 12.5" is max vehicle track width

Re: Josh's Y-Town Crawlers "Villain" Shaftsmen Build
 

Nice build so far. What dremel bit did you use to hogg out the final drive trans gear?

thanks, http://www.dremel.com/en-au/Accessor...l.aspx?pid=194
this is the bit i used, drilled out one of the holes big enough to get it through the gear then just worked away at it.

Re: Josh's Y-Town Crawlers "Villain" Shaftsmen Build
 

I understand the advantage of the offset pumpkin. Any top 1:1 rock crawler has them.
I guess my question still remains. What about overall width?
The XR mod with Creation Fab tubes to get VP Wraith knuckles, XR universals, awesome steering AND XR width seems to be the trend these days for anyone with an AX10.
You are actually going the other direction and making the axle AX10 width.....that's where I'm confused.
12.5" is max width and it would seem you would want to stay as close to that as possible for stability and tire clearance for tighter steering (rubbing shocks, links etc.)
Since there's also a max tire height, you could argue that the wider axle causes more hang-ups due to the tires being much farther apart. I only have stock width experience, so I wouldn't know.
Am I missing something?

Re: Josh's Y-Town Crawlers "Villain" Shaftsmen Build
 

By the way I'm in love with this chassis and super jealous.
Don't mean to bog this thread down with my questions.
Thanks everybody for your input.

Re: Josh's Y-Town Crawlers "Villain" Shaftsmen Build
 

narrowing it actually makes it the width of the front xr axle"thumbsup"

Re: Josh's Y-Town Crawlers "Villain" Shaftsmen Build
 

This is a comparison pic lifted from krawlfreak's thread
http://i1179.photobucket.com/albums/...4608c0af08.jpg
In it you can see the narrowed ar60 is the same width as the xr10 housing, which in theory should be very close to the same width as an ax housing w/ tubes.
