Hey guys, well, to finish out the year, I figured I would upload one of the more troubling repairs I have made in the recent months. While This may look like a simple fix to some of you, I struggled. Things don’t always go as planned and a lack of tooling doesn’t help either. So kick back and cringe as I did on some of the things I was having to do. If anything, you will see that we all struggle from time to time no matter how experienced you may be. Thank you for your support and I appreciate the comments.

No sweat, it's fixed. A field expedient repair. And the customer got it back on short notice.
That heater u own
may be defective.
i have the same one.
If when u shut it down,
it does not do a 3 minute cool down,
it is defective.
Mine has a thermostat.
If it shuts down on thermostat
it does a 3 minute cool down,
but if i shut it off,
using the power switch
it just shuts off
and that is wrong.
Isaac, dont you think that the arc is too long for aluminium? I usually use shorter arc.
not too bad
Looks like cummins isx accessory drive that the air compressor mounts to that surface thats broken off I believe thats not a dowel pin hole its the oil supply port that feeds the air compressor the big hole is the oil drain back
Im positive you can buy those as a reman or possibly get the housing i used to rebuild those really easy
Press off the spline drive and it comes apart
Yep nothing to say Your good
is the video sped up or am i tripping
This is the first video I've seen of yours and I learned a few things. With your operating expenses, still and experience, does the cost of a repair like this exceed the value of the component?
I think Im going to reschedule tomorrows dentist appointment for later.
Good video thanks no artificial and selected repairs, reality.
That part connects the High Pressure fuel pump to the gear housing on a Cummins 15L engine. I've never heard of one breaking like that. DId the customer tell you how it happened?
Great Video! Nothing new from the newer miller?
Think it’s a Cummins N14 accessory drive. Used to be cast iron with replaceable bushings inside. Now make of aluminum and housing is bushings. Throw away part now
I weld a lot of oil impregnated cast aluminum. That casting is pretty good quality compared to some. I use an E3 (purple) electrode with great success, it seems to recover better when you dip the tip. Another thing that works for me is after cleaning and weld prep with a carbide burr is to go over the area to be welded using cleaning action only, no filler rod. That burns off the last of the impurities. Great job!!
Great job. Its never easy fixing stuff especially when its hard to get at and keep everything clean with welding aluminum
Sharpen your tungsten on a grinder works a lot better on aluminum !!
That looks good am not a professional welder by no means but steal and sheetmetal i can weld but aluminum not really I bought an aluminum boat to try to learn but never got good at it
Belt sander may have worked
Not sure if it’s the same for everyone but the video is sped up at certain times
It looks like you are bleeding some air from the backside of the welds. You might find it easier if you bled gas onto the opposite side of these welds.
Love the real world repair on a tough part to repair
Cummins ISM accessory drive. With your labor, it would have been less expensive to buy a bare housing, but, I get it if is 3 weeks out
This is the most liked comment in the history of comments.
Might not be “Pretty” but if it works, it works. And I’ve flattened cylinder heads with sandpaper on glass. Nothing wrong with that.
How many amps / hz you welding it?
I’ve got an aluminum head I need to weld up a crack, hope my 200A welder will do it .
Turned out all right for the technique I would have used aluminum brazing/gas welding wrap it in KO wool to maintain the heat.. Sand groove from the outside toward the machined surfaces so the puddle can get in and proceed to braise all flat surfaces will maintain their dimensions and very little sanding will be required… I also recommend a graphite rod for oil passages and bolt holes…
happy new year guys!
Thanks for. sharing the way things really are. the video that shows all the pretty welds are for the most part aren't the reality that I see in my shop. I appreciate the thought process and I do learn from all your videos. Keep them coming.
