Is the red aluminum diff cup for the rtr or exb diff? You probably have the wrong ring gear on the cup. I believe I already pointed out the issues people were having. Rtr and exb diff parts are not compatible.
Interesting that the rear had no issues.. these are arrma aluminum diffs. Never had any problems with hot racing version either... but the end result. I shaved some burr off and it's like butter.
The diff cases are identical there isn't a front and rear.Interesting that the rear had no issues.. these are arrma aluminum diffs. Never had any problems with hot racing version either... but the end result. I shaved some burr off and it's like butter.
Not what I remotely said. There universal.. the way I said it though.... I already have my rear installed without issues... front was given me issues. But I know that there not....
I might have worded it wrong. But simple answer. I know that there identical. Think though the lack of sleep and somehow the wording. You're not telling me anything new lol. I was simply stating that I had to dremel the other one so it fit properly. Felt to tight.
Makes no sense that the plastic diff fit but not the aluminum one. If the aluminum was built correctly than it has the exact same dimensions. That's why I asked if there were rtr and exb parts mixed to build that diff.
The diff cup is the part of the diff itself the housing or bulkhead holds the diff.
So housing and bulhead are the same. Whats the difference between the diff and the diff cup? Or is it not a diff without the diff cup with the diff cup being a component just like the ring and pinion?
I believe the issue was the diff he had built was a combination of exb and rtr parts by the picturesI saw. I tried to help awhile ago... this thread really should be taken down.
GP5’s do not need to be on EXD diffs. Just need to make sure they are straight cut. RTR GP5
Find the part numbers for all those parts. I'm not convinced it's the same ring gear. Exb and rtr cases are not the same width. The exb ring gear in the picture I commented on should have had flat head screws. The gear on that diff you linked has to be different to keep the same diameter. I have built and rebuilt hundreds of these diffs. Simply putting an exb ring off an exb diff on a rtr diff doesn't work. Please end the confusion, lol.
That is correct, you cannot swap the parts. You have however incorrectly identified the part. The GP5 ring gear you see has those screws because that is what goes on the straight cut GP5 pictured. I’ve included the link from Arrma so you can get all the part numbers you need. In short, the user installing a straight cut GP5 gear on a RTR diff is supported. Arrma GP5
That ridge on the gp5 ring pictured tells me it is one that would come on a Kraton or Mojave exb diff. The one on that amain diff does not have that ridge. That is why those 2 diffs pictured have different dimensions.
I think there is a miscommunication, what you have circled in the second picture is the correct GP5 gear. In the first pircture that is the EXB GP5 gear. Those are not the same gear. I’ve included a picture of my 31mm GP5 gear as well as yours.
There's the issue.
And just to be clear none of these are mine. I was just trying to help someone obviously mixing up parts.
