Hows my gear pattern look? 9"

Working on my gear swap. I previously set up my 4.33s (they were brand new and free from my brother) but were way too much for steet use so im going to a more street friendly 3.25 in my 9inch. Heres some pics of my pattern I think it looks pretty good but hopefully some of you pros might just give me your opinion. I did the 4.33s my self even though they only ended up with 5-600 miles on them they didnt make any noise and they held up behind my 532BBF. So I at least like to tell my self i know what im doing

My backlash according to the markings on the ring gear are supposed to be at .008 I have checked in 10 different spots and im at .0085 to .009 should I try to adjust or leave it be??? Thanks!!!!!

Pattern looks good to me, best I can tell from the pics....I like .009-.011 on street gears,so IMO,you're good enough there too...One question for conversation sake,do you check the wipe with a load,or no load, on the pinion flange?

I use a old soft sanding block to hold pressure on the ring gear. Then I'll put a drill on low and turn it a few times each way. Seems to lay down a readable pattern

Looks great

That looks great. Just make sure you get enough carrier bearing preload by using a proper tool of some sort to apply 150+ft#'s of torque to the side adjusters. A huge cresent wrench with one 1/4" holes in each jaw to hold hardened roll pins works well and the wrench is reasonable from HF.

I use a otc brand spanner wrench designed for Toyota timing gears I think. It has screw in pins for different sized holes and also has a 1/2 square Hole for using with a 1/2 tq wrench
I can get the part number if anyone is interested I use it for all kinds of automotive projects. But I have never used it on a Toyota timing gear haha

Heres the tool, Works great in a lot of situations with all the different "pins" Since its adjustable with the 9/16" nut in the center it works great for tightening down harmonic balancer bolts with an extention, i cant see how it wont fit anything any car guy would need it for (maybe not some big diesel stuff)

That is helpful -- Nice tool! Thank you

Just be aware the torque reading on a tq wrench will be delivered to the spaner multiplied from the wrench reading depending on the angle and total length of the wrench system relative to the tq wrench itself.
