gear wear pattern?

Well i just did the wear pattern and i think I need to just move everything closer to each other, but im not 100% sure so what do you guys think?

 

yea put a shim on the pinion. didnt you put it together without one?

 

I was thinking of that I'll start with the .010.
What do you think about adding a shim to move the carrier closer as well?
Or should i wait and check the pattern again?

 

First, What rear end do you have?

 

Start with a pinion shim in the .035"-.037" range.

 

That gear pattern is way off. You need accurate measurements when doing this job! What your Back Lash(BL)is measured @ will tell u if you need to add any more carrier shims and also tell you which side to put them on. No way to know unless you check your BL. I would put a .035 pinion shim in it and get your BL in the correct tolerances which is normally in the .008 to .012 range, then check the wear pattern because the BL does effect the pattern a little bit. What ring & pinion brand do you have and what rear end are you working on? Also you need pics of the coast side.

heres the answer to all your questions..

 

Attempt number 2!

 

looks close but get a better opinion maybe jim or devon will say somethin whats your backlash?

 

I ust double checked it ands it's low according to the specs. Coming in at .004-.005. Jim is that monza guy right?

 

too tight use a smaller shim

 

or maybe the shims on the side are wrong.

 

pm greatscat to get an expert opinion just checked he is online when i do rear ends i usually have to take them apart 10 times as i dont know all the tricks.

 

Ill redo the sides cuz I put the smallest shim I had in the pinion. Will see what comes of it and I'll pm that dude.

Thanx I'll compare them in the morning.

 

If you want us to help you need to list the pinion shim thickness and the baclash on each attempt.

Your pattern appears to be pretty darn close. It is a runner. What is the backlash set at and MAKE sure the carrier preload is tight enough. YOU SHOULD NOT BE able to pull the carrier out of the case by just tugging on the ring. HAs to be tight enough to have to use a slight bump with a pry bar.

Also try more dribbles of gear oil on the ring and spin it around 3-4 time also PUT some load on the ring gear with a rag wedged between the case and the edge of the ring ...this will create MORE pressure to really giv ethe compound a squeeze. Jim

 

attempt number 3!
backlash .008-.009
I added .010 to the right of the pinion.
One thing though the gears seem to be tighter now by the feel of turning them.
