Tjm pro locker?

[506Montero]

They are solid, more reliable than ARB.

Saving for a set for my stupid Nissan Patrol, but almost $4k and kind of hard to justify.

Do it! I wanna see.

I may have to investigate too...

And thanks for the thread. Never heard of them.

Or maybe I'll just pickup extra actuators, and or build a lock out piece. At least you can just pull the cover and switch actuators.

What's your experience with them?

second hand, good relationship with the distributor (Costa Rica) and been around them in a couple of trails of different cars. Less leaks than ARB, never seen one broken. Neither a broken ARB, to say that.

They are pretty solid, not made of chineseum (have seen those fail awfully).

FWIW TJM is reevaluating their locker program. After reading through this thread I was super interested in their toyota SKUs but they are all out of stock but not discontinued yet.

Yeah, I noticed that the one I got was out of stock at TJM.

TJM = Jack McNamara

Here's a rambling history from his kid.




And the air cyl circlip. I'll get some measurements on mine later. Grainger sells internal spiral locks.




Too much one-wheel peel =

Well actually ARB is not. The 2 o-rings constantly wear out as you drive. Every revorlution of the wheels makes the o-rings wear a flat and then the diff lock leaks air and diff oil goes up the air line into your air compressor and fuckes that up. ARB also have small bolts holding the diff lock together. We modify ARB diff locks and put bigger and more bolts in, to make it stronger. Dad designed the TJM Pro locker 40 years ago to fix all the problems that the ARB air locker had. After he sold the design and patent to TJM they started making the tjm pro locker. And they kept making it incorrectly with mistakes after mistakes. Dad kept telling TJM the problems they are doing and they didn't listen to him and just kept making them incorrectly. But the things they were doing are so mynewt that it is still usable. We have videos showing the problems. But if I was going to buy a diff pock I would go with the TJM Pro locker because it is a stronger diff lock in every way.

re: comp lock.

Maybe room for springs in there to keep the 4 pylons pushed into engagement, then just a matter of flipping the air cyl to disengage?

Here, more spam.

Air cylinder by itself, $150. "Out of Stock". WTF?

Looked at their site, hoping to see some 9" options. Maybe in the future.

Same. Looking for something better than ARB's standard 9" air locker and cheaper than their $2500 comp version.

FWIW, I took my cylinder apart.

I don't think it would be so easy to flip. Not just "bolt it on backwards", anyway. Maybe if you remade the bottom part in the diagram above so it stuck out the other way...

Both my circlips were nice and tight, but both were installed backwards, with the rounded edge out. I flipped them so the sharp edges were out.

The bore is .75", with a .025" deep clip groove.

Was deal thread, now TJM locker install thread

^ it was not an issue with the lockers, more of a dealer to distributor disconnect. The closeout deal was at Summit Racing because they were dropping the TJM product line all together( they inventoried most of TJM AU catalog of products for several vehicle platforms.) and they were blowing out...

FYI as you are installing the solenoid to your compressor manifold (where you connect your locker air hose to the compressor) from the orientation of the inlet and outlet of the solenoid isn't marked so you're left guessing which side connects to the compressor and which side connects to the compression fitting.

The side of the solenoid with the wires coming out faces the manifold- also if you look inside the solenoid block where the 1/8 fittings go you'll see one side has a larger hole (inlet) and the other side has a very tiny hole) outlet. Another clue telling you the larger opening is the inlet side.
