OK, so here it what I have going on. I burnt the stock servos the day after Christmas. Since I have to do the Servo, why not get a GKA Mount? Ordered, a Savox 1210SG water proof servo, GKA mount, and 3 servo horns, because I wasn't sure what would fit. I had wanted to shim the diffs and swap the fluid out, but wasn't really ready to spend the time fixing something that wasn't broken. Then I win a set of Fast Eddie bearings (thank you Arrma Forum). So now to get to the bearings I have to get inside the differentials anyway. And another order is made. 2 sets of the mugen diff shims, and some diff fluid that is most likely WAY too thick. I am going to try 80K in the front, 500k in the middle and 100k in the rear. Along the way I picked up some thicker sway bars, Hot Racing Chassis Braces, New out drive cups, a Hot Racing metal bell crank, Hot racing center diff carrier, Stock motor mount to cut down for a center diff mount, and a voltage hobbies steering rack. I also picked up a set of the stocks screws on ebay. I figured I might strip a few getting them out, but I found some rusty ones in there. I guess I need to do a better job of drying and lubing the car when I wash it. And the red aluminum wing mount button looking things. As spares I also have set of dog bones.
Last night I got the green light to spend a few hours wrenching the Kraton. Heading for the front diff first. Since I hadn't taken anything apart yet, I really had no idea what to expect. Started on one hub, and completely removed the whole assembly, trying to get to the differential. Realized there are bearings to replace in the hub....duh...wasn't thinking bearings, only diff at the time. So I swapped the bearings on both of the front hubs. And set them aside.
Now onto the differential. I have no idea on how to get to this, but I thought I could just pull the front plate off and get to it. But it seemed like there was more to remove than I thought. So what the heck, both the top and bottom Arms off the car, sway bar off the car, front shock tower off the car. Damn, this is looking like one heck of a puzzle to put back together. Finally get the entire bulkhead off the car, and still can't get to the differential. A little elbow grease and a screwdriver used as a mini crowbar, and the front of the diff comes off. I guess that will be easier next time.
I first worked on getting the bearing in the front spur gear swapped out and then moved on to the shims.
I pull out the Kindle and queue up Thomas P's bullet proof diff video on you tube and get busy. Really not as hard as I expected. I laid everything out just like he has on his towel, and followed him set by step.
By now it's been a few hours and the wife is getting a little bit antsy. "see Dave, this is why I don't like this. You can't just do a couple hours, it's gotta be all night, or nothing." I am trying to explain that I can't just stop working with a dis-assembled differential. She doesn't get it, oh well. it's been 17 years, she's not leaving over an RC Car. I really wish I had a power driver, because my driver handle is small and it seems like those screws are a mile long after while.
I wanted to get it to a stopping point, where I knew I could remember or easily figure out how to get the rest of the front end back together. So I got the bulkhead back in, and secured it with the 2 screws, through the chassis.
I still have to replace the shock tower, upper and lower arms, and the shocks, but I am super proud of myself to sat the least. All the bearings up front are swapped out, the diff is shimmed, diff fluid swapped for 80K, and is half way back together.
I think tonight I am going to be able to get the Front Arms back on, and may just do the front Chassis brace, even though it may have to come off when I go to do the steering mods. Only a couple screws so no big deal.
I will have to do the rear end before I do the center diff, since my New Center diff carrier is being shipped right now. So maybe I can get the rear end taken down tonight too, or maybe I'll just cut that motor mount down so I don't leave the car in too many pieces tonight. Either way I am at least 3 hours last night, and look to have another 7 or eight hours to go.
She my not leave, but I'm going to hear it when it takes me another 3 session of 2.5 hours each. Guess her birthday should be a little extra special this year.
