Whats the torque on the carrier bearing bolts? and the ring gear bolts?

I gotta do a quick gear change tonight, actually cange the mini spool out. I bought one that was supposed to be a 28 spline, well its a 31.

Could someone go over with me, what i need to do to change one out please?

Thanks, Krom.

Your going to want to mark the caps so that you know which side they came off of to start.

Pull the 2 small 1/2 inch bolts holding the carrier stops out

Before you pull off your carrier cap bolts, feel the gear with your hand on one yolk and one on the ring gear, feel any play in the pinion to ring gear.

Pull your caps off, and skrew the 2 caps off the ends. Now your carrier will pop out.

You'll have to pull the ring gear off the carrier. After you do this, you'll have to split the carrier apart to get to the mini spool and cross pin dowel pin. You'll drive the small dowel pin out of the carrier through the cross pin.

Then just re-verse the steps, using a good air impact to put the ring gear back on. I like to use a little red loc tite on the ring gear bolts though.

When you get to the point of getting the carrier back in, Install the carrier, and then the caps loose, and then skrew the cap ends on to set your lash between the ring and pinion. You'll want to adjust the gear side to side to get your lash by turning one cap end one way and the other the opposite. You'll want your cap's to be tight enough that the gear will not move in the case but loose enough that you can use a hammer and a punch to turn the carrier cap ends. Once it is all set and good, spin your yolk a few times to check everything. Then hit the cap bolts with the impact again, pound them on there. Then re check your ring gear bolts, bolt the gear in and go racing.

Pretty self explanitory, just have to do one to get the hang of if.

Built my first "hog head" friday night, and ran it saturday, and it didnt come apart and performed flaulessly.

Thanks all for the help and pointers.

Do you guys check the back lash with a dial indicator? and if so what measurement is a good setting?

I set mine by feel, if i had to guess it had about .020 free play, is that to much?

Also i tried to make sure that the end caps were screwed in enough that it wouldnt move side to side, but still spin freely, the ring gear. Is that the only way to do this or is there a way i can measure it?

Thanks, Krom.

WAY TOO MUCH, I BELIEVE IT'S SUPPOSED TO BE CLOSER TO .008". I SET ALL OF THEM WITH A DIAL INDICATOR.

I usually set mine at .005" excessive backlash will tear the gears all to peices due to the rocking effect it will have on the gear teeth.

I USE A SETUP SHEET FROM MOTIVE GEARS OR RICHMOND GEARS AND BOTH SAY TO CHECK IT WITH A DIAL INDICATOR AND SET AT .008-.014 OF BACKLASH.
IF YOU LIKE I CAN FAX IT TO YOU UPON REQUEST.

SOUNDS LIKE YOU DID A GOOD JOB KROM. GOOD LUCK, LET ME KNOW HOW THE CAR WORKS FOR YA. , YOU HAVE MY E MAIL. RON

Actually it was alot easier than i thought it would be, you know how alot of folks like to mystify things to make it seem alot harder than it is.

Anyway, i will put a dial on it, and reset the lash this week. We actually gotta do a gear change so i'll have time to go over it again.

I hope UMP goes to a quick change, just so i dont have to change any more Hog heads, man them things are heavy.

.008 to .014 sounds good to me.
