Kraton Bigger pinion

[Dakota]

Anyone noticed when they put the bigger pinion in ,the truck sounds a lot louder and a lot different is that bad or normal ??

Sounds like your mesh might be off. If it is just louder it may be too loose. If it whines it is too tight.

With the new v4 sliding motor mounts don’t they go pretty much we’re they are supposed to ??

No you still have to set the mesh. The sliding motor mount just makes it easier to position.

Awesome thanks guy I will loosen the screws and make sure their is a little gap between the teeth but not too much ..
I think I might have them to close right now

may want to check your gear mesh again but also harder grade steal vs soft steal makes a louder noise also

It was in too tight I lousened it a bit so theirs a little bit of a gap but not to much

Just make sure you check it all the way around like in the video so there's no binding anywhere. Not all gears are "perfectly" round. Glad ya got it figured out though.

Looks good to me as well

 

[PowerDubs]

Looks good to me too
If anything, back it off just a smidge but it won’t matter really

 

[martysmith223]

feels like a loaded question lol

Looks perfect from where I am. ? But that don't count.

It’s difficult form the camera angle but it looks loose to me. I personally like slightly firm gear mesh contact, but not too tight.

I was afraid of that. I thought it looked good too, but while driving I'd here a frequent crack sound. Could it be one of the diff. They're probably about due for a relube, but I didn't think it'd tell me by being so loud. I check temps on the p/s and it was 150F at the end of the run. It's a 14T pinion on a Kraton and I was bashing. Moror temps stayed right at 140F the whole run. BTW, it drove fine except for the subtle cracking sound. Sound familiar to anyone??? Advice / help much appreciated!

Looks loose to me.

Do you think that was the cracking sound?
