2011 HDI project

[foxvalley]

Looks like I may be doing some work on a 2011 HDI,as I awoke to find it in my driveway. The unit belongs to a large powerline co., and just waiting for the ok to start tearing this thing apart.
I drove it off the trailer, and motor, tranny seem to be in good shape.After cleaning all the junk out of the unit, I dicovered that one of the idler chains was laying under the sprocket,and there could be damage to the axle and or sprocket.
There was lots of large square nuts,and assorted metal floating around on the floor, and I'm guessing something got in between the chain and sprocket.
All the chains need to be replaced, as the sliders are all in their highest point.
The unit is in fairly good shape with the LCD showing 150 hours,and waiting to take the rubber tracks off,and check how many bearings are out if any.
The biggest issue I see so far, is that it looks like this thing was overloaded,and the rubber tracks got into the tub on both sides, and tore it all up. There are two large holes,about a foot long, and 3 or 4 inches wide,and part of the tub looks to be gone.
If anybody has any ideas on the best way to repair this, I am all ears.
Once I start, I will post pics of this job.

I saw the same issue once on 2 hdis where the tracks wore a hole thru the tub with low hours on both machines come to find out the avenger tires were too big to use on factory rubber tracks odg covered them under warranty

Sounds like they should trade it in on a new one. And I could buy this one for a project, and save a few bucks. I look forward to your posts your royal swampness.

LOL tbone9, I think I'll go fishing now with the large can of worms I opened,LOL.
Looks like they have the largest tires in the back,I'm sure that didn't help matters. The unit has a rops on,almost looks like they tried to lift the back up,as the back looks higher than the rops?

[tbone9]

Well I hope your repairs go good. This is definitely the right place to get good information.

Thanks bone, This Co. trade their units in every 5 years(if they last that long) They will be "extremley"affordable,and I might have some info when that happens.

[tbone9]

Thanks, I'd be interested. I know how people treat equipment when it's not theirs. If it weren't for that I'd be out a job.

I just recieved the green light to go ahead and start repairs on the HDI, later today I will take the tracks off, and check the bearings,take the tires off and start to proceed with the front axle where the idler chain broke. The idler sprocket has slid about 3" over, so this is where I will start. Lots of minor things,cable on high low range very sticky,also the throttle cable,more than likely they will be replaced. Also an issue with the parking brake. New ignition going in. Will get a better look at where the tracks burned into the tub, and will post pics of this.
Pulled up the history on this unit,looks like the tranny had work done to it,but seems to be in good shape now. There are new lug nuts on two of the tires,looks like work had previously been done.

I take it the manservant will do all the graft whilst one takes tea ?

[foxvalley]

LOL rodp,no time for tea, but maybe a crumpet?

The sprocket on the front axle is froze in place,and not lined up with the idler shaft, so I am cutting out the axle and going to replace both the axle and the sprocket. The outer bearings are all good, but the front bearing is contaminated with sand and dirt from the removal of the axle,so I will be replacing the bearing ball.
The rear tubs on both side are a mess, and had been feebly repaired with a hunk of plastic, and pop rivets.Some of the damaged erea was cut out. I might try to patch the erea with the same material that the mud flaps are made of.
Parts order going out today,including all the above, plus all new chain,sliders,springs,etc.

I think I saw a manservant once, he was talking funny, and wearing lots of pink.

The closest thing to a manservant around here is, after you get married,we are referred to as, "gofers,or melons"......... Honey, gofer this, gofer that,...............or honeydew this or honeydew that.

[rodp]

Yep, I know the feeling

[foxvalley]

Well, the axle is cut off,and with "murphy" helping out as always, the sprocket just slipped off after the cut was made, go figure.It was in bad shape,so we will still replace it.
The bearing is on the cut axle pretty good, so I just ordered a new flange,along with the bearing ball.
The bracket for the winch got bent down into the tub, and did put a hole in the tub itself,so I am going to jack up the bracket,and hopefully get it back into it's original position.Plastic epoxy should fill in the hole, as it is a small one.
Going to try and get all the chain off before the parts come,also will take off all the sliders.

[foxvalley]

Took off all the chain,half of the retaining clips where missing on the master links.Parts came in,prefit the sprocket on the axle,and also took the paint off the axle where the bearing will be seated.They overspray the axlehub and the paint has to be scraped off, or the bearing will not slide over the axle.
Put the flange, 3 gaskets,and bearing on axle,reversed the bearing so the set screws are facing out,(they assemble them facing in from the factory)and slid the axle in,slid on the sprocket,then found out I had to loosen the inner bearing flange to give me wiggle room so the axle would slide in.I put the bolt and compression washers on the end of the axle,now just need to slide the sprocket over to give me room to retighten the flange and the two set screws on the inner bearing.
I will also wrap the outer bearing set screws with a little electrical tape to keep the sets clean, and to seal it tight.

Sounds like your movin right along. What did you figure out for repairing the holes in the tub?
