Some people flip every other pinion, effectively locking the differential…

I would assume you are speaking of the 8 pinion trans,?

No sir. No need. 

My tractors are built HEAVY so I get traction.  

 

Also worth considering is that a locked rear does NOT want to turn. 

I've had great concerns about breaking an axle so I leave all our machines as either Open Diff 8 speeds or Limited Slip Differential 6 speeds.

8 pinions I've seen. 

10 I haven't. 

IMHO it's pointless to weld or lock a 10 pinion because it's already a Limited Slip Differential.   Locking up a 10 pinion could lead to easier damage than an 8 pinion because the pinions are smaller and the end plates are not as strong.

Obviously, this is not a guarantee that it’ll perform or last as you expect.  These are not trucks and are sometimes treated as such.  Individual results may vary :handgestures-thumbupright:

Recommended for ages 8 and above - some assembly required, batteries not included, may not be exactly as pictured, etc.....

I flipped every other pinion and it locked one side. the other axle spins free. Not engaging the pinions

How many pinions?

If it's a 10 pinion it might not lock that way. 

Only 8 pinion diffs work that way and each set in sequence needs to be opposite.

In stock form it's every other pinion. 

To lock it, have two opposing sets of two headed the same direction.  

I have an 8 speed open on the bench so I can get you pics tomorrow morning if it helps.
