This job is something that I am seeing more and more of. Customer brings a part and tells me that it is almost $3000.00 to replace, and no used ones exist. Can you fix it?
Absolutely, I can fix it. This job saved my customer a ton of money and a long lead time. He said the part would be about 2 months out from the dealer. He told me the New Holland equipment is being obsoleted in short order and parts are almost nonexistent. He can still source this, but not easily.

My father was doing plumbing in a commercial kitchen and someone knocked over a large oxygen tank and broke off the stem which than it became a torpedo. No one was hurt as it went through a wall thank God . Please chain up your bottles. I was just watching random videos enjoyed yours but noticed your gas bottles not secured.

It's always good to be able to repair expensive parts and save customers a fortune as opposed to them buying a new part. It also works when the part is no longer available, as it saves an old machine so they don't have to spend an even bigger fortune to replace an expensive machine.

@Invinciblemoam 2 ай бұрын

It’s always best to heat the whole part in a something like an oven rather than localised heating. When heating with a torch the expanded material close the centre has nowhere to go since the outside of the part is still relatively cool this can sometimes make the bore smaller!. In this case it was the underside that must have had a heat induced taper. I love your videos and never see you make a mistake without explaining your reasons for/against afterwards. I work for a UK based engineering company with 14 years tool based experience, just passing on some knowledge an old timer kindly/angrily gave to me

@user-dy6fy6bx6p 24 күн бұрын

True. Judgement is used as to how best heat it. Cracking on cool down is a big issue with localized heating of hubs with spokes. (Not applicable to this repair) Really old flywheels had curved spokes to address the cool down issue before they figured out how to make the straight spoke castings cool after casting without cracking a spoke. I have lost a few spoked pulleys by only heating the hub. They make a loud bang when they crack a spoke during cooling.

We have an older Ken more self cleaning wall oven. On really difficult pieces we can leave it in over night and freeze the pin the next morning. Press it in and put it back in the turned off oven and let it cool down in there.

I enjoyed watching this repair. My best experience with a precision shrink fit was on the cutter head for an asphalt milling machine. It was 3-15/16 dia. And about 5” long. The interference was 5-1/2 thou so I specified dry ice and heat to 300 deg. F. Because of the bore length we set the parts up in a 30-ton press just in case, which turned out to be good thinking. There was definitely a bit of pucker factor as temperatures try to equalize quickly. Those dry ice fits sometimes make interesting sounds when seating. Thanks for sharing this one.

I used to do some similar sized ones. Since LN2 is not readily available here,dry ice is the best bet. We always went to 400° for safety. Needed the press one time.

Those coax indicators are a pain to use. I always use the good old edge finder to find center. It works better and easier. Most people don’t know this, but it will find the edges of holes and pins just as accurately as it does linear edges. I use it all the time to find center by zeroing one side of the circular feature and the distance to the opposite side, then splitting the difference. It’s much easier if you have a DRO.

Big thing about using dry ice vs LN2 is -109 degree F vs -320 degree F, you only get about one-third of the shrink; gotta keep that in mind. With LN2, the part probably would have dropped right in (at the expense of 2 hours driving to get the stuff). Anyway, nice job there, it's always interesting to see how people approach a problem and get it done.

@TopperMachineLLC 2 ай бұрын

It would have been 2 hours of driving for dry ice, that is why I make it. LN2 would be 3-4 hours of drive time, making that unacceptable. I can't bill for time and materials to get supplies for a simple job. I wish I could get LN2, it just can't happen here, too depressed of a region.

Just a note about sawing off the pin with a slitting saw, slitting saws are pricey but my favorite alternative nowadays is the 8 inch carbide tip blades they sell for metal cutting skilsaw type saws. They are cheap like 40 bucks and less kerf, I have one on an R8 arbor I use all the time for cutting down pieces too short to hold in the bandsaw, slotting, or even have used it in the angle head for cutting plate clamped down to the table. Works great and in 4 years now I am still on the first saw blade of the 2 pack I bought!

That was a high stress moment... averted.. Better to set up the press-shrink fit in the press with the press ready to press before heating the part while the stud is cooling off in dry ice. If the stud is even a tiny bit off axis even with a few thousands of clearance the stud will likely get stuck on the way down the hole. More often than not, the press I needed to avert a Oooops and not fun at ll re-do.. There is a tendency for metal to stick when they are close together, this is why clearance alone is not enough. Some means of mechanical aid (force) is often needed to over come this tendency for separate metal parts to wanna cling together.
