Rear Differential issue

Just a note about the gear mating surfaces. Prussian works, but so does a good blue sharpie...

 

I read somewhere that the venture rear has the lowest ratio. Anyone ever try or hear of that swap mod?

 

Hit the Diff specifically on the outer Axel Hole, and you don't have to go crazy either. One or two solid swat's and you should be in Buisness. Good thinkin Skylrk62...

 

Really? How can you resurect a 9 yr old thread and not notice? Just cost me nearly an hour going down all the rabit holes that are @skylrk62, and his development from "differential" hitter to turbo monster builder.
Excellent.

 

I noticed lol, Google Direct's you to a lot of these Old Thread's if you Run a Search. So if I can save a Man 20 Minute's of beating on an differential with no Result's, I will haha.

 

1: It's not a differential (there is only one driven wheel).

2: Hitting it is not a solution to any problem. Proper diagnosis and repair is.

 

When I say final Drive Gear people kept thinking I was talking about a Chain drive, obviously it's not a limited slip Differential when there's only 1 Wheel. Just used due to lack of better word.

 

And I Created a Post on here asking if there was a Sequence it needed to be Torqued down in, basically asking what I was doing wrong and nobody Responded. Then I found this thread in a Google Search, and what He did worked for me too. But just beating on it doesn't do the Trick, you don't have to "Beat" on it at all. Couple solid Rap's to the Axel Hole freed it right up.

 

Final drive is what it is. It's what Yamaha called it.

 

Instant responses are not guaranteed.

Final drive reassembly requires special tools (that can be fabricated at home if you have the ability). I'm happy that your method worked, but in all honesty you got lucky.
Hopefully the gear mesh wasn't disturbed.

 

I have about 300 Miles on it without Issue yet, I think it's ok. It feels Normal, but I suppose I could be chewing something up. Any idea why it's getting hung up like that? It happens after snugging the first Nut, and it doesn't matter which Nut you Start with.

 

It's because you're not using the special holding tools to keep everything in place. That causes the pinion to bind on the ring gear.

 

Makes sense, gonna have to keep that in mind if the situation ever arises again.

 

Had the crown wheel inner oil seal and needle roller bearing replaced on my XJ650 FD unit today. When "boxed up", the FD unit didn't spin freely. If the flange nuts were backed off a little, the unit spun up ok. The answer is to put a thinner shim in and try again. Have ordered some new shims and will wait to see what the results is. Should solve the problem.
