440IC with 602 Blade and Winch

I bought this last summer, knowing it had a blown LH final drive bearing. Starts and runs, good hydraulics, winch controller needs to be oiled and bled.

I didn't really pay attention to the undercarraige but after I got to looking I figured out that it had Berco links, ID 61/ID62 which are for a 2010. It still had the original sprockets (M3098T) so they were wore a little due to the larger bushing on the rail.

At first look, the bushings had absolutely no wear and rail height looked good so I thought they would be in pretty good shape. The master pin had been welded, but other than that, I had high hopes.

Image

I contacted Lavoy in the winter to look into getting 350 sprockets welded onto 440 centers in order to not wear out the bushings or further deteriorate the sprockets.

I blew the master link out with oxy-acet and got the track split. That's when things started to go sideways...

With all the dirt and oil in the way, I never noticed the crack in the case on top and the broken piece underneath. So my final case is wrecked, little more than just a bearing...

Image

Here's my little pile of parts out of the final. The axle will certainly need to be built up and machined. The bull gear and pinion is a little rough, the clutches are completely soaked so I suspect leaking seal in the transmission output shaft. One spring was broken on the throwout carrier. There is lots of brake band but its completely soaked with oil. The springs on the pressure plate were ok, going to replace it anyway. The throwout tube is bent up, the bearing itself was still ok, all the other bearings in the case, with the exception of the outside axle were still ok. There is some play in the spline of the axle and bull gear, not bad but still some.

Image

I sold the Berco rails (not the pads) to a guy not far from me. He is going to install them on a 350. Once I split the track, I realized that there was a lot of play in the pins so it ruled out keeping them. The pads are in nice shape, with welded on grousers so I will hold on to them for now. Someone might need pads, they're in nice shape.

I am organizing getting some parts now. Found a decent set of rails with dozer pads, with good sprockets. I am going to keep pulling it apart. Next project is going to be pulling the RHS track. That final has had some work done to it recently so not sure what to expect there. I will try and fix these pictures as I can't get them to a better size.

These are the casting numbers on the finals. At first I thought maybe I had 2 different finals but the parts book says the T10004T subs for the T19406T.

WIth the track off I was able to check out the rollers and front idler. All 5 rollers are loose, quite bad although the rollers themselves actually don't look that bad. Does anyone have a diameter for a newer roller? I think maybe it was the slop in the bushings that caused the rail wear on the pin bosses as opposed to the roller itself being worn. The front idler bushings are gone as the idler will hit both sides of the track frame. Also, there is a ton of welding on the track frames and all the mounting bolts are broken or loose.

Maybe I bought myself a blade and a winch?

Hi,

Yep. You bought a blade and a winch. But, it is better than that. You bought yourself a *project*! Something to do! Keeps you out of the bars at night....or, drives you to one! :P

At least it came to you completely assembled. Not on two trucks! ;)

Keep with it. When you get it done, and push that first blade full of dirt, you will love it! :)

I was able to get a 1/2 hour in on the disassembly yesterday so I started working on the RH track. Whoever had worked on it before had tried to make a master pin and they drilled and tapped a 3/8" bolt in the end and washered it up. It was quite loose but it seemed to be working. Also, I was happy to find that the RH hydraulic adjuster was in quite good shape and holding the tension on the track very well. I opened the screw and jumped on the track and they let off. Another positive on this side was that the front idler, carrier roller and all 5 bottom rollers are very tight and have lots of meat left. The track frame looks good and there are no welds. I was sad to find that they had blown the dowel pins off the axle and replaced with bolts. Maybe they couldn't get the sprocket off?

They also added homemade guides and some pretty fancy screws.

This is the hydraulic tensioner from LH side. That track was very loose so it looks like the seals had blown out. I'm not sure if you can see from the picture but the fix was to jam a piece of angle in and hold it in place with a snap tie.

I pulled the RH track out today and got it loaded on a pallet. The front idler is nice and tight, same for the upper carrier roller although it is worn down pretty much to the end plate, it was still not loose. Good news - the rollers on the RHS are all in really good shape and no slop in them whatsoever.

Now that the tracks are off I am going to take the winch off and then pull the transmission with the clutch housing and the RH final attached. I will probably get the blade off but I hate to just yet as it is a very handy way to get the front of the crawler up.
