JDcrawlers Messageboard

I would like to sell my crawler. It has a rebuilt engine that was bored .040 over w/ new pistons. and I have put new seals and clutches in the final drive. I used it to excavate and put in roads on my property while building my house. I am selling it and going to buy a wheeled tractor that isn't so ...

no load on engine when using valves. all valves are affected . would one ball out of place affect all the other valves. at the end of the valve assembly is what looks like a valve body with no spindle or handle that the pressure line and the return line go to. I took it apart but there are no parts ...

I have a 50 backhoe on my 440ic. while doing some digging I lost power and range of motion on all hyd. cylinders. the first thing I did was check the fluid level , and it was fine . Next I changed the filter, and while the old filter was quite dirty, there was no change in performance. when I switch...

On further inspection, the seal does look like leather.

Good morning all, A while back I replaced the seals on the end of the shafts of my track tensioners. Yesterday one track when slack and when I looked close there was a whole lot of grease coming out of the barrel. pushed the seal on the end of the barrel right out. I took it apart and the seal looks...

What does the bendix look like. I don't see one in the parts breakdown?

I believe you are both right. I pulled a starter out of another 440, and it works great.
I would like to rebuild the starter, are all the necessary parts available?

The starter I replaced it with turns over slower, could it be a 12V?
It looks identical to the other.

If I jog the starter switch on and off it will engage after two or three times, and then it will start.

It use to work fine. The grinding is a new development.
I cleaned it good and lubed the drive mechanism.
Grinding got worse.
It doesn't have a bendix, it seems that the rotation of the starter throws the drive gear out, and a light spring retracts it after starting.
Near as I can tell anyway.

It is a 6v system.

The starter on my 440 doesn't always engage and it makes an awful grinding noise. I pulled it and the ends of the teeth on the starter are showing wear. fortunately there is little damage to the gear on the fly wheel. The starter looks fine. Is there anything I can do or is a rebuild in order. Thank...

I triple checked the direction of the the Thermostat before I bolted it together, so I am sure that it is in the right, however, I see that the manual calls out for 160 degree for gasoline engines and I installed a 180 degree. I wonder if this could be a problem?

Thanks Duke, I am running, however, I am over heating after about 50 minutes of operation (the bulldozer is too:). I installed a new thermostat and new cap on the radiator, but sill getting hot. I guess that leaves the water pump or the radiator. I don't even know where to get radiator work done aro...

Yes Lavoy, I was kind of thinking that way. This is the second machine I have pulled the final drives an, and while it was easier the second time, it wasn't any more fun. I noticed on a previous visit to this site that you had a seal kit for sale. does that have seals for both the axles and the ones...

I just pulled both final drives, and the left side had about a pint of oil in it and the clutch and break band was drenched in oil. This would probably explain why I could not turn to the right, or when pushing or going up hill it would turn to the left. The inside of the right side was fairly dry, ...
