What is acceptable snoot wear?

[mattshup]

Hi guys. I’ve been reading a bit here and there on the forum about how you can build up the snoot so it doesn’t leak oil. With Ni55 rod?

How much is considered a lot of wear. I have a caliper that shower 2.66inch on the 9 and 3 o’clock position, while showing 2.58inch at the 12 and 6 o’clock position. Is that too much wear and needs build back up?

There also appears to be a wear mark on the inside of the hub? I’m just learning as I go here so really appreciate the insight. This last year of full send windmilling has taught me so much.

Matthew , looks great to my eye , a new bearing instert would be a perfect solution to any wear .
Just my opinion for what thats worth , MIke B

Personally i would try to repair it.On hands experience is the best way to learn weather you fail or succeed you learn from both.

You dont have a normal wear pattern because the end play of the hub shaft is off. There is lots more than .08 of wear but not where it usually is. It can be repaired Ni 55. The hub shaft is pitted and worn so when you put in a new shaft, the end play can be set correctly. The inner hub ring looks fine but to be sure you measure.

The inner hub ring is also worn down in one area. I was looking at that further today. I have one more donor 702 case that I might crack open and see what shape it’s in before making executive decision with this one.

Well I sure gave it a fighting chance. First time ever doing it. I think I need to build up a little more in a couple spots but I ran out of rod.

I did but a groove in the top like I saw Ron say to do in another post somewhere.

Not bad. A few more and it'll be like riding a bike !!

Just like a good caulking gun is to a woodworker, a good grinder is good for a welding person.

The weld or buildup being round is the essential ingredient. The tolerances dont allow for being off much. We used to check buildup with calipers but after a couple assemblies of getting the hub shaft within a 1/4" of being home and hitting solid, I got sleeves machined for mill sizes 6-12. It seems a more foolproof way to check
