Title: Gear-One 930 Midboard Hubs Repairs *#@***!!%###
Post by: fabr on April 14, 2015, 09:07:54 PM
Few pics showing the shaft repair sleeves from SKF (and others) First and third are of the sleeves with flange that allows the thin walled sleeve to be easily driven on with the correct press fit. Last one shows how the flange is designed to allow it to just be peeled off easily. Second shows sleeve with flange removed.

Soooooo,everything went as planned,repairs made,torquing the cv through bolts and guess what. THREE OF THE EFFERS WERE STRIPPED OUT. Likely from the accident a couple years ago. DAMN!!!!! 5 days till dune trip. Figures.  ANOTHER next day air charge IF I can get G-1 to answer their freaking phone. Freaking unbelievable.

 Gear -One continues to be on my CRAP list. There is absolutely no reason for these repairs being needed .The repairs needed should be part of the design from the beginning considering the use of these things.

Yup. $700 bux. The large repair sleeves are $134 each alone!!!!! The 4 sleeves and 2 of the seals are SKF ,off the shelf items. The large seals are G-1 available only. Custom size things. I was amazed though that the 2 large seals from G-1 were the least expensive items!!! $35 bux each.

Well,guess what. They have upgraded (seems like a common BS theme in the offroad components world)the aluminum parts that should have made from steel all along. Only a $750 upgrade! Oh ,the killer part,THEY HAVE NONE !!!!! Soooo,it's helicoils for now. bs1 bs1 bs1 bs1 bs1 bs1  The lady was very nice though. eyes eyes

i know there could be a few that disagree with me about that having anything to do with stripped holes etc etc but  still  ;D
does kartek (  or another competiter) offer a set like these or are these based on there design? if so what do they make there's out of?

It appears that all brands of midboard hubs used aluminum originally. All apparently found out that was a bad idea. GEEEE,YA THINK !!!!???!!!?????? SFAIK know,all either have changed to steel for all components but for the hub itself or offer it as an option today. Just my luck. Hopefully the helicoils and steel repair sleeves will hold up  and I will skip the $750 for upgrading to steel components. I feel pretty confident it will work. The helicoils can be a full .750 long instead of just 3/8ths or 1/2 inch long as most are. The cv bolts will engage the full helicoil length. I would use a solid thread insert but ,no room or at least I feel too much material would be lost and strength would be definitely compromised.

Bad luck with the parts mate. Any chance you can tell us the bearing part numbers just out of curiosity?

I'll try to remember to look later today when I get to reassembly.

Thanks. Just another thought, you could have drilled and tapped a new set of holes between the old ones if you wanted.

Post by: fabr on April 17, 2015, 05:56:32 AM
  Crap,I forgot,in the rush , to get the numbers. I still have the other side to do. I'll do that side when I get back from this trip,didn't want to chance further issues with only 3 days to go. 
  Drilling another set of holes wasn't an option I wished to use. Best option was the long length helicoils. Did the repairs on the mill.Came out perfect. I'm not likely going to spend the money to upgrade the components with steel. The sleeves should stop further excessive wear and the heli's will prevent more stripped threads for a lot less $$$$.

I'm not listening to any of that pig stuff. My car is around 1800 with sand tires,a bit more with dirt tires/wheels.

Front to back empty is about 25/75 With me and wife in the car then it go's to 30/70 so not much change.  interesting to know is with just me in the car the balance stays the same at 25/75. I am going to run the rear spring pressure up to nigh because the car is sagging some in the rear.  Plus I had 300 psi in the shocks before I started the over haul of the them and I only put 250 psi back in.  I am going to run them back up to 300 psi.  Getting the oil level right mite be a problem all so. All the information I have on Fox shocks say to fill the shocks to 6.5 inch down from the top of the barrel and that is with no shim in them.  So with about 2.5 inches of shims to keep my droop in line at 22* I put the oil level down to 8.750 from the top of the barrel.  My spring pre load was 2.0 inches down from to top of the shock but wen I put them back together with the new spacers I had more spring then shock.  I had to use a spring compressor to get them to gather.   With that I only run the adjusting nuts down and inch. Mite have to run them down some more.  I'll be kingmaker some finial adjusting while at the dunes.

Save your self some money and mix the water with e85 instead of the meth.  Jerry and I are running it now and it works as good as the meth.  Keep the mix at 40 percent e85 to 60 percent water and your good to go at around 2.25 a gallon compared to better thee dollars a gallon.

Did some diggin after I read that you were running that, and not 100% sure pump insides are compatable with the 15% gas.  Granted it be dilluted down, but?  Running 30% meth washer fluid.

You do still have a CNC mill right? Those would be pretty easy to whip out in steel if you have any more issues.

True,very true. The 2 seal surfaces should be ground though as opposed to milled/turned.I'd have to farm that operation out. On second thought though,my spindle speed is 10,000 rpm. Hmmmmmmm,I'd hate to eff up and explode a wheel but it would be doable. Honestly,I thinkthere will be no more issues other than wear in the seal area but the sleeves are a simple service item now.

High helix EM will give a good enough surface for a seal to run on.
