JDcrawlers Messageboard

They don't always come off easy, but you need to pop them off to make the adjustments. As for putting them back on I don't think they are needed so left them off, just make sure the locknuts are set. There are a number of posts about them on the crawler boards. I think some have put them back on, mo...

I think the pump on the unit should be fine at those dimensions as long as it doesn't loose fuel. I think you may want to look at having a check valve and a manual primer pump to help with bleeding after filter changes.

I think most I've seen were plywood with cleats attached, one or two might have been thin cut boards. Using wood over the batteries makes sense if you think about it, lessen the risk of a short as it protects the positive battery terminals even if slid to one end of the battery box or the other. I t...

I too believe that is an original. I remember seeing a number of crawlers with those over the batteries, even if the tool trays were missing. The parts book shows AT18737 as a plate, NLA. The drawing looks like this as well.

It is good the pads and grousers look good, but the condition of the chains, rolls, idlers, and sprockets are more important in determining the amount of wear, life remaining, and how well the tracks will stay on, in my opinion. Is any grease visible around the adjuster on the track that is slack? T...

D = 6410 outside blade T = John Deere Dubuque Tractor Works (build location) When you say the tracks look good, are you referring to how the pads and grousers look? I would expect the chains to be worn it the sprockets are worn. How close to the ends of the track frames are the idler brackets? Stan ...

Have you set up an account for the server with Lavoy? It is not tied to your log in here.

Bruce has a good, commonly used fix. I've also seen brazing, TIG, or MIG used, depending on processes available and skill levels. As for getting a new tube, one way would be if you can find an industrial hydraulic shop that deals in process tubing such as used in mills, power plants, etc.; they shou...

Suppose the drive hung in and took the starter way, way overspeed? That will mess a starter up bad, in a hurry.

Some oil burning heating systems do have excess fuel return lines, just not as common. You need one port for the fill pipe and the second will handle the vent, whistle and gauge using a combination unit like this https://www.homedepot.com/p/Beckett-King-Fill-Alarm-and-Gauge-14525P/202312890?MERCH=RE...

Pulleys belted together as you describe will both turn the same direction.

Good to hear you found the problem and got it repaired. Its always nice to know what solved a problem and it completes the post, doesn't leave folks wondering if it got fixed.
Best regards,

You say you saw steam from under the tin. I would locate the source of the steam to see where it was coming from and if the spot could be repaired, before just dumping a sealer in to it. It might require removing the tin and running it a bit. You might get a radiator pressure tester and test for a l...

Welcome to the board. Just so you know this post will likely get moved to the late model board. That is where the 350s, 450s, and later models belong. The hydraulic reservoir is the tank under the right armrest. The transmission oil reservoir is the case of the transmission. Totally separate systems...
