660 differential mount/support

Guys,I have another 660 in the shop.A perfect model to make a real fix for the 660 chassis flaw.What I haven't told you is my first 660 chassis diff mount/support mod was a total disaster.I wish I had pics of what we did but I don't.When his Rhino went problematic I basically fixed it the same way every diff support I've seen on the market does for support.The problem is he used the receiver box in the back of the chassis.He got stuck bad enough they jerked on it and the leverage applied from the receiver broke the extra bottom bosses off the differential.Then I went threw the hassle that I did on the last one you seen in here.My fix will not be as easy to install but if the mount is already damaged it will fix the issue.I'll update this tomorrow as I get further into it.I'm trying to make this as painless as possible but I can see now way around welding.This will however update it far and beyond the 700 chassis update from the 660 model that Yamaha did.

do u plan on possibly selling one  like your last repair  I think u would move quite a lot of that design know I would grab one fast as possible

It will be similar to the last one, minus cutting the factory mount out of it and using a jig.I'll post pics when I get back to the shop.

Baxter..I own copyright laws to the wht rhino..... hahaha..... this is the first of several BBF parts for this machine

lol,I hope to finish yours up tomorrow night Wht07.

I'll get a price worked up for the kit if anyone is in need of one.

Here is a pic of the pieces I made to drop in the top.I just need to make some spacer to go in between the plate and the factory mount and a longer bottom bolt.i'll try to make some instructions to help.

Oh great now I'm going to have to use my Awesome welding skills lol 
Well they're not too bad until I have to overhead weld then I think I have more slag on my neck than weld on material lol

lmao! There will be no overhead here so you should be golden.lol I've never heard it quite put that way before but that's funny.

Great Idea. How much are they going to be ?

I'll let you know asap.Trying to get this one done, hardware and all,and make sure there is nothing else to add.

nice!!

Last piece of the puzzle going in the Rhino on the lift. I'll have diff mount/supports coming very soon.It's going very smooth in this Rhino considering the Rhino is pretty busted up.I'll have a drill bit ,as an option, in the kit. This 12" 7/16 drill bit makes it so you don't have to take the diff completely out.I'll make that your decision.The shop is filling up with these things. Lol

in picture of mount is that the fill plug behind the mount if so can u get plug out an be able to add fluid if needed .

I think it's just the way the picture looks.There is plenty of room there but I will look at it tomarrow because it almost has me convinced it's in the way.lol

cool if it's not put my name in pot for one when u start selling them

The kit consists of (2) grade 8 7/16"x 6" bolts ,(5)SAE flat washers,10mm lock washer and 10mm x 30mm bolt and 2 brackets with 1/4 thick spacers welded to them to space the brackets out far enough to get around the factory mount.This gives the bolt a 1/2 of material on ea side to eat threw instead of the 11 gauge sheet metal it rips threw and rids the twisting motion applied by the diff to the factory mount.In addition wraps around to the lower boss on the diff for additional support.Kit cost is $85.00+ shipping payable threw PayPal.For an additional $20.00 I'll send a 12" long 7/16 drill bit that will save some time from having to pull the diff out of the machine to drill the holes out to 7/16.The factory bolt are 10mm and you can not get a long enough bolt to go threw all of it in that size.You'll probably find that you'll be 1/3 of the way threw your diff before you start to remove any material because the twisting motion egg shaped the holes in the chassis mount and the diff.You will need a way to clean the factory powder coat off,welder,and a drill with a 7/16 drill bit.If you have these tools your as good as gold if not take it to a local weld shop that does.I know that seams like a lot to fix a factory problem but this kit in my eye's is the only way to fix your problems with your 660 chassis and not just put a bandaid on the problem with one of the other diff supports.I've found some very misleading info out there.I've been down the road of a bolt on diff support to find out later it causes problems else where if you continue to use the Rhino in hard conditions.Here are some pics of the one I installed tonight.The factory mount on the drivers side had cracked and fell apart.I just cut that side off to give the new bracket a flat surface.If you find yourself in this position you need to space the diff bracket out the thickness of the factory mount.Otherwise the bracket will hit the diff..If interested PM me here or feel free to call 419-953-8509 with any questions and I'll get you fixed up.  
      

Here is a over head pic of it before I welded it in.

As soon as this motor is paid for I will be ordering 2 kits. 
Awesome job and the price is right!

after I get back to work an catch up some fun funds I will get one right after the new year , an x2 on price

Nice kit , post your contact info

Just let me know.I'm busy posting it on other sites but I have 8 sets ready to ship at this moment.

Mounts are in the mail Jay.Thanks

alot of the cross tubes breaks too that i seen..maybe you can add one that you slide in the stock tube to beef it up too

I see what your saying James.I might try that on the next one.I put a support on the bottom of the last one after I jacked it back up straight.It wasn't very user friendly and wouldn't advise someone to loose their knuckles putting it in.lol The twisting motion that the factory mounts allow is what fatigues that back tube till it finally cracks. I looked at 2 more 660 Rhinos last night.One appeared to be fine the other the front mount on the rear diff. had a hairline crack in it.The one with a crack was bone stock and only had 1800 miles .I'm making it a point to look at as many of them I can find.He had a 3rd at his shop that we couldn't get to.I'll let him get caught up and go back at a later date.The guy I sold a kit to yesterday had one of the diff supports that bolted to the receiver box and it broke the boss off the diff.and ironically I found 2 places advertising the receiver style supports and claimed it's to avoid cracking of the aluminum diff housing.I've seen plenty of these Rhinos thrashed and trashed and have never seen the housing break unless it had a receiver mounted support on it.lol It's the sheet metal tabs holding the housing in that let's go.I'm not saying that the receiver mounted supports are junk by no means.Any extra support is better than none. I'm just saying there is a flaw there that could possibly make a mess.
