Difference In Diffs Be1 To Be3

[ericdean 0]

Hello Folks

 

I've just bought a LSD in a BE1 (Lift up reverse) gearbox for my brothers track toy without checking what 'box was in his !! The 'box in it is a BE3 (right & down reverse) my question is will the LSD fit into the BE3 or do I need to change the 'box and lever etc?

 

Thanks in advance for setting me on the right path!!

 

Cheers

Almost certain the diff is interchangeable between be1-3. but if you are changing your box over from a be3 to a be1 im not sure how you get around selecting reverse? Sorry cant help anymore than that.

If it's a LSD then it will fit BE1, BE3 & BE4

Hello Folks

 

Just a quick question, I've just read a post about the crown wheel being different? Does this mean that I need to swap the gear ring bolted to the diff ie: remove the BE1 ring that is on the diff and put on the BE3 ring?

That is correct. But count the teeth on both crownwheels first. If they have the same number of teeth, just swap it over including crown wheel. It would be smart to change the bearings though!!

Just a thought - a mate of mine swapped the diffs over for us and it meshed together perfect, no force required.

To me this sounds like the right crownheel for the gearbox?

Must have the correct wheel then.
