Nothing to exciting. I completed drawings for a new chassis that will be a lot more finished looking. Waiting to have that machined. Started tearing the truck down to finish the small details. Here's a game plan

- Take anodizing off integy shocks and rebuild
- Lock rear diff and rebuild front diff with thick oil
- Sleeve links with Acetol
- Mount servo brackets and servos, links etc with new hardware
- Rebuild maxx tranny to single speed

That should keep me busy until the new chassis gets here.

Here's the shocks now. Hopefully they'll be silver tonight.

Man..Finish that thing, then take a vaca over here and we can hit the trails!!

jeepcreep · 02-24-2009, 07:40 PM

So how did those shocks turn out?

NickRummy · 02-24-2009, 08:35 PM

Not a good turn out yet. EZ off wasn't working well by just spraying it on and letting it sit. I was trying not to get it inside the shocks so the inside stays smooth. Not sure what to try.

NickRummy · 02-27-2009, 08:38 PM

Well these shocks proved to be a challenge. The easy off oven cleaner ended up working. A few of them cleaned up after soaking for about 15-30 minutes with them being taken out about ever 10 minutes to make sure they weren't etching. The other parts took almost an hour...

Then I picked up some mothers aluminum polishing compound. $9 for the big tub.

Smeared a little on the shock reservoir and body and took the buffing wheel on the dremel and gave it a good buff. Made a mess doing it but it came out pretty nice! After another round with the wheel I think it'll be really nice. I am not sure how to clean up the threads though. Here's a shot of one that has just been stripped of the anodizing and one that had one round of buffing.

Hopefully i'll get the chassis in soon and can start putting this thing together.

jeepcreep · 02-28-2009, 12:17 PM

nice, man. It looks great! I sure can't wait to see those on your truck.

NickRummy · 02-28-2009, 09:14 PM

I'm going to try 40wt with a single MGT spring first. It feels like it should be WAY better than the previous setup.

Servo bracket powder coated black and mounted up. I used FFRC servo clamps. They should definitely help from breaking the mounts off the servo housing.

Links are all sleeved so all I have to do now is finish up the steering links.

jeepcreep · 03-07-2009, 01:01 AM

sweet job man.
when are you expecting the chassis?

NickRummy · 03-07-2009, 10:43 AM

I was hoping it would be finished by now but the guy making it has been extremely busy lately. Hopefully it's not much longer.

jeepcreep · 03-14-2009, 03:14 PM

got the chassis yet?

BiG_DaWgZ · 03-21-2009, 01:43 AM

GREAT BUILD...on a MAMMOTH TRUCK !

jeepcreep · 03-31-2009, 07:43 PM

updates?

good looking rig you got there

Waiting on a chassis to be machined.

NickRummy · 07-28-2009, 07:28 AM

Well it's come to my attention that no one is willing to take on machining these big chassis plates. Oh well, I'm sick of the truck sitting on the bench in parts. It has to go back together. It's just to fun to drive not to.

So back to the bench with the UGLY pieces and parts mock up chassis! Changed around the upper shock mounts since there are reservoirs now. Finished polishing the shocks. Swapped out to MGT springs which look like they'll help for sure. I think I'm going to end up limiting travel and lowering it a bit but I won't know for sure until the body is mounted up again.

I've been wanting to tear into the trans for a while. It's made some not-so-good noises last time it was ran and I've been wanting to get rid of the two speed to simplify some things. I've never really looked to see how the E-maxx tranny worked so I tore into it.

Definitely some parts of gears in the wrong places

Drilled out one of the lower gears with an 1/8" bit in two spots (already have hole indentations there)

3mm x 30mm hex head with a flanged nut. (2) places

Gotta slide the opposite gear on just to use it for a spacer.

Kept both top steel gears since one is needed for a spacer, removed one of the idler gears and the shift fork and linkage.

Spins A LOT more freely and no slop to speak of. Now we'll see how long these plastic gears hold up. I doubt much longer.....

jeepcreep · 08-06-2009, 04:49 PM

sick... even with the old chassis plates.

kind of a bummer that no one would machine those for you though. :-(

TANK08 · 08-23-2009, 12:00 AM

that looks like it would be a blast in the snow

NickRummy · 08-23-2009, 11:17 AM

Yeh it's definitely fun.

I have an update I'll have to post in a bit. I got it all back together and running. Took a few pictures and some video and too.

NickRummy · 08-23-2009, 01:19 PM

Got it up and running today. Found out that the upper links didn't have the right length of all thread them. First pull of the trigger ripped two of them apart

Got those redone. The airtronics servo for the rear steering wasn't strong enough to hold the rear wheels straight under power or while cornering since the rear axle is locked. Ended up taking that off. After modding the front knuckles for more steering and changing to a hitec 5955 servo it steers pretty well now.

I think I'm going to gear down though. It's pretty fast and unstable at speed. As you can hear in the video the trans gears are toast. I think it might be the trans case flexing and allowing the gears to slip?
