Toughbox Assembly

[mjgard]

Has anyone else had problems assembling the toughbox? I cannot get the large bearing over the large shaft. I tried using force but it barely starts and gets stuck. Any recommendation to getting this piece on. I am afraid if I use to mush force it will get started and I wont be able to get it back off.

[Coach Norm]

We had difficulty with getting the pins. We had to get extras before we were successful.

Good luck.

We are a Rookie team and the AndyMark Toughbox was our first successful assembly in FIRST.

One thing down and counting.

Someone else was having trouble with the large bearing. You may need to make sure it's straight first.

[Mike Rush]

We had the same issue with the bearing. It appears to me that the finish on the shaft is not very good. When it was turned to size there are small ridges remaining on the shaft. To correct the problem take some abrasive cloth and remove a small amount of material. I did this on our small lathe using an emory cloth to smooth out the finish. The bearing slips on easily after the finish is improved.

We had some trouble too, but I took it to be because of the close tolerance. The bearing has to be perfectly straight to slide on smoothly. A dab of grease on the shaft helps. We also used a deep well socket and tapped gently with a hammer to get it set.

i am having the same problems with it. ty will try these suggestions

Things that you can do to make the bearing go on to the shaft.

1. Put a dab of grease on the shaft and "wiggle" the bearing down onto the shaft.
2. Use emory cloth or scotch brite pad to smooth the surface of the shaft.

***Do not try to lathe down the shafts*** The dimensions of the "trouble" shafts that I have seen do not require more then 5 minutes of scotch brite/ emory cloth work.

lathe??? our teacher had to spend about 10 minutes per shaft with a sheet of sandpaper sanding it down to size. but it works now so woot! note: try to sand evenly so it wont turn into a metal oval

Use the provided transmission mounts with the kit bot.

Today we were looking at assembling them (possibly reducing them to one stage for speed...) and i found that the pinions would not fit on the CIMs. They go on about 1/4", then they get stuck.

My team had the same problem. You can use a deep well socket and lightly tap the gear down onto the shaft. You can also lightly scotch brite the shaft of the CIM.

We used a rubber mallet to get the bearing onto the shaft. To get it back off, we put a bolt in the end and put the bearing on top of a vice so that the shaft was inside and the assembly is resting on top. Simply use a mallet to hammer the bearing back off or for a more safe approach (as to not strip any threads), try pushing down on the bolt.

Our toughbox's are assembled nicely and our stuff should be coming any day now so that we can install two more CIM's. Are we supposed to get a shipping confirmation from Andymark? We have not gotten ours yet and we placed our order before 3pm cst on tuesday.
