Hate Bad Welds

[Kubotasrking]

So I've been off digging holes stayin busy on the TC45D for the last couple years. She has done a heckuvalot of clean up work on my place...every waking available hour we worked to clear trees, tear down junky old buildings, and generally improve our property. Posted a pic of an old building that was built mostly out of garage doors (66 doors used as floor, roofing, siding, and of course...doors:laughing. Big blue was awesome in the process of ripping that eyesore down.

I'm working on the main entrance doing some grading when I hit the forward pedal...and I don't move. After some serious looking around for the issue, I find the bracket connecting the pedal assembly to the transmission is not turning when you hit the forward pedal. I also found an incredibly bad/ugly weld on that very same bracket that occurred sometime prior to my owning the tractor. It looks like someone stuck a stick up into the bracket/shaft area and globbed on a weld that is just nasty...

The problem is that it appears to be a major task to tear down the tractor to remove the operators platform. I'm contemplating cutting an access port into the floor of the platform, make the repair, and weld it back together... Time is the issue...spend a lot of time at work, not a lot of time available to get into a major job that calls for the removal of the platform. Anyone with any advice?


At any rate, it is really the only problem I've had in 4 years of ownership, and >1000 hours of service.

Sounds like a defect in design or a quality escape.

Now you know why the repair was done the way it was! It was to time consuming to do it correctly.
I'd also ask the local NH dealer why this part has failed twice in 1000 hrs of operation. There might be a redesigned replacement part to preclude this from happening again. If you're going to fix it right, maybe you'd want to see if there is a better replacement part available.

It really only failed once, if the repair was all that bad.

Someone must have been in the garage door replacement business.

Pictures of the old barn you are tearing down but no pictures or the weld problem

Post some pictures that way some uf us that don't own that tractor know what you are talking about and may be able to offer some insight.

But if it is just a vertical or overhead weld that someone tried a home repair on with a stick welder, wrong rod, and wrong technique, try taiking it to a weld shop. Out-of-position welds are not impossible and can be just as good as a horizontal-flat weld. IF you have someone that knows how.

I would post you a picture, if it were possible to get one.

It is a bracket that should be bolted to a rod that exits the HST. It is an inch or so below the operator platform, inside the pedal/cruise control assembly. In other words, can't reach, can't really see it (would have missed it if it weren't for the weld...)

Here is a link to a previous thread on this issue by Jinman. As normal, he did a great job of documenting what it took to replace the broken part (complete with photos). I recall another member that cut an access hole in the floor but was unable to find the thread. This seems to be a common problem with the earlier class 3 boomers. I just keep my fingers and toes crossed as mine has the old design of the part (two small welds instead of a complete circumference weld) and I know it is a matter of time before it fails.

I know what you mean about the time constraints. It always comes down to no time to fix it yourself and no money to pay someone else to do it. Good luck with the repair and keep us posted.

Kubotasrking, what a shame! Wolfpack2 has given you the link to my old thread which is the best advice I could give you. I do have more photos than I posted here on that thread, so if I can help you in any way, give me a PM or post here. There is already a hole in the platform over the running gear that you will see when you remove the rubber mat. To help remove the mat, I cut the mat on the side where the joystick is so I did not have to take the hydraulic lines loose. Once the cowling is reinstalled, you cannot see where I cut the mat. Here are a few pictures of the area. Two of them have the broken part removed so you can see how tight it is in there. I don't think you would want to be welding because the black plastic wire loom also has the fuel line running through it. I suppose with a wire welder, you might be able to weld in place, but I'm no expert.

Well I have her down to her skivvies now, it will just take a few more hours to remove the controls on the l & r sides. I saw that fuel line running through there, and couldn't help but think how miraculous it was for the last guy who welded on it that he didn't catch the fuel line on fire going both directions.

The part definitely has to come out to be cleaned up and rewelded...I guess it will be my next few days off project. Winter in the Pacific NW will keep it interesting...it is monsoon season.:laughing:
