Funny, when I bought my second M275 I got it from Bruce Kubu. At the time he has Jumbo the M125. When we arrived at the farm Jumbo was out. After prepping the little tractor that could, I pulled it up next to Jumbo. Think deuce compared to Zuk Samurai.

All fixed, and so far the locker works great.
The last pic is the 2 missing spider gears that were in the bottom of the housing. I had to scoop all the shrapnel out after draining the remainder of the gear oil.
If I have to do this again, next time I will buy new nuts and studs to bolt the chunk to the housing, instead of dealing with dirty and stripped threads.

Would somebody please explain what these "lockers" do? How many do you need for a deuce? Are they different from the front axle lock-out hubs?

Thanks!

No one better to explain than the maker!

Seems there would be a lot of wear on the tabs from them being spring loaded against each other in turms

The design has been in use for years. They are preferred over a Detroit locker in off road community. The more torque difference the harder it is to ratchet. They work good. Not recommend for front axles unless lock outs are used. You can't steer otherwise.

The Grizzly is preferred over the Detroit?

Thanks Phil! You're right- great explanation.

I did some reading and some people claim that lockers make tire scrubbing in turns worse- also that lockers can cause under steer and other problems when coming out of a turn, especially on snow & ice. I thought lockers would improve these problems- no?

 

[gimpyrobb]

NO.

Steering characteristics are way different.

Especially on ice!

You have to learn how to drive with Detroit's (or Grizzly's). Driving normal with cause some interesting things to happen and most likely a bunch of pop's and bang's or a good solid bang felt through the chassis. When approaching a turn, like a hard right from one street to the next, lift and let the truck slow on the engine as you make the turn and the locker will stay open. The work by engaging when power is put to them through the driveline. Lift on a turn, less tire scrubbing and smooth turning. Accelerating through the turn and you'll bind up stuff and wait for the reactions.

The "Detroit Locker" was the first "Locker" unit made. The "Grizzly" and "Eaton" lockers are just different manufactures of the same thing ( actually Eaton bought out the Detroit Locker). The patent ran out years ago, so now anyone can make a Detroit Locker "Style" differential. I know most people don't care about the semantics of differentials and what is and is not a "locker" , but as a gear mechanic it really bugs me to hear people use the wrong terminology when describing different types of differentials . A "Posi-Traction" is not a "Locker" is not a "No-Spin" is not a "Torrington" or "Helical Drive" . They are each a different type of Limited Slip differential. It's like going up to a Mustang owner and saying "that's a cool looking 350 cid engine you have there" . If he didn't shot you on the spot he would at the very least tell you to get lost ! Or tell a Camaro owner that his 318 cid engine looks great. They are all engines, just not the same engines. Same with differentials.

Never accelerate on a turn with a Locker differential ! Not unless you like to replace axles on a regular basis .

Talked to another Ag customer Friday that said the deuces they used to use went through axleshafts a lot. I think the reason recreational users don't break them as much is because we don't use them as hard (over)loaded.
