Where to get cast aluminum welded?

I disassembled my tire changer thinking all I'd need to do is change the bearings to fix a wobbling turntable, but found the upper gearbox case cracked at the bearing mounting surface. Any reputable places to get this welded or otherwise repaired instead of just throwing a band clamp around it? A new gearbox guaranteed to fit is $1600 from a reputable parts supplier or I can take my chances with Aliexpress for $500.

Anyone used Vangro? They have the most reviews by far in my area, and 38 out of 39 ratings are 5-star, with a single 1-star rating relating to price. Never even noticed this place living in Mississauga almost my entire life and driving past it often.

Won’t be cheap. But they are VERY good

Welding is tough on cheap Chinese castings. First, it’s gonna take a lot of time to disassemble, welding ADC1 castings at stress points rarely holds up ( and it won’t be cheap unless you have a friend.)

I’d measure the od then but a a simple split collar to slide over. Amazon has a lot of sizes.

I'd disassemble it before bring it in - 5 bolts and the top lifts off, then press out the bearing (or it will fall out because of the crack).

OD is about 90mm, but where the neck sits when assembled, there may not be clearance for something like that. For all I know this has been like this since I bought it, so a band clamp should be more than sufficient if I can't get it welded. I'm also waiting for Bendpak/Ranger to get back to me on the cost of a case half.

Would they be aluminum, stainless or mild steel?
