You might be able to add an extra shim to the clutch pack in the diff, if there is one? and tighten it up, or weld the thing solid. But other than that, no.

Nope... I doubt that there is any such aftermarket parts ever made for them. Why? Because they already are... functionally the same as a locker. :)

They are very strong front diffs. Generally have to run them without oil for a long time to kill them.

If yours is failing there are used ones for sale on the fLeebay. Some are very low priced too.

If yours is slipping & making a snapping sound it can be fixed by putting different gear oil in it than the 80w90 it calls for.

Welcome to the forums!

What year have you got? Got any pics of your 350D you can share...?

1986. Don't have any pics on the phone. She's a hand me down. Dad bought her brand new. I've had her about 10 years.

It's "functionally" nothing like a locker. It's limited slip at best, and in reality more like an open diff.

OK, but mine is 30 years old and works like it should. Can you explain to me why/how I got so lucky when all the others, even new ones, are functionally open diffs?

Mine functions as limited slip. Always has as long as I can remember. The bike is 1 year older than I am, dad bought it new.

So your front end acts like a locker how? YOU explain to me how your 30 year old Honda front diff acts like a locker, and I'll explain how it acts like a open diff.....

Ditto for the one we had, bought it new in 1987, sold it in 2005. Was a great machine in it's day, still is now, I can say many good things about it, but having a locker isn't one of them lol

Now now gents, play nicely ;-)

On the locker issue.... I really wouldn't weld it, I shimmed my 300 front diff twice, once was great but the second shim (thicker) pretty much locked it. I never got to try it out in the mud because it was so damn hard to steer I took it out and left it stock!
My source for shims was very limited in choice but I'm sure, if you wanted to, you could shim them up just a little and still be able to steer with some ease.

A locker acts like a spool when power is applied to it, yet will allow one wheel to slip while making a turn.

My 30 year old front diff acts like a spool when power is applied to it, yet will allow one wheel to slip while making a turn.

The only functional difference between a locker and a limited slip is the choice of clutching mechanism built in. Neither are open diffs, those have no clutching mechanism whatsoever.

Wrong. Your front diff does NOT act like a spool, ever. Get one tire in a bind and the other will spin, whether the wheels are turned or straight it doesn't matter, it takes very little resistance at one tire for power to be redirected to the other. As a matter of fact, I wouldn't doubt then FSM for the 350 refers to it as limited slip as well? When I referred to it open I meant that's about how useful their LSD is compared to "real 4wd" like you THINK you have

I never said it did act like a spool! I stated that a locker and a limited slip were functionally the same. They just use different mechanisms to achieve the same result. Open diffs have no locking capability.

I'm lost ........ Is the ops dif down ? Or is he just wanting to tighten it up , as mac said welding or shims, You can cheat that front dif, like this, and still have good steering, unless he's wanting a full out mud machine.

Jmo and not ment to ruffle feathers , the trx350d or foreman s are great machines but aren't that fun to drive in the 1st place , a locked front dif ? Would (to me) be even worse ,and limit the uses greatly...

I guess I'm being too subtle?

"Nope... I doubt that there is any such aftermarket parts ever made for them. Why? Because they already are... functionally the same as a locker. :)"

*******

"A locker acts like a spool when power is applied to it, yet will allow one wheel to slip while making a turn."

*******

"My 30 year old front diff acts like a spool when power is applied to it, yet will allow one wheel to slip while making a turn."

You guessed it, *******

"The only functional difference between a locker and a limited slip is the choice of clutching mechanism built in."

More of the same.

"I stated that a locker and a limited slip were functionally the same. They just use different mechanisms to achieve the same result."

Here we go again....

I really don't think you grasp the concept of what a locker means in the world of ATV's.....
