If you see a leak at the filter bleeder screw by all means fix it. That should be under pressure and leak more when running but it could let air in when it sets. It sounds like you still have an air issue. I wonder if the fuel transfer pump could be getting weak. If it was slow priming by hand that ...

It happens. Several years ago at work I had parked my pickup after running an errand and all was fine. A couple hours later I had to go pick up some piping parts for the crew, got in the truck and absolutely nothing. Borrowed a voltmeter and checked the battery - no voltage at all. Luckily I was wor...

I have been looking also. The only thing so far has been some outfits selling clips from 2 to 6 inch long of grouser bar to weld on the two - one pattern on the existing grousers. They help a bit but they are still skates. I have welded cheap bolts and nuts on before as caulks and that helped.

Use a voltmeter to check to see that you have power as you progress along. Start at the battery(s) an be sure the battery(s) haven't failed. Check the cable ends, battery posts, and ground cable attachment. Does your have the battery master switch in the battery box? I had seen those fail, try bypas...

Good afternoon. You are 100% sure it is a C with wet clutches? I only ask as the 450s seem to have a habit of turning up with C decals on them because people don't understand the serial number system when they get repainted. The 450 steering clutches are different than the 450C steering clutches and...

I think 1/0 was original and should be fine. 2/0 is the next size large, will carry more amps, and will work fine as well, but may be a bit harder to bend.

Is the driving factor behind your thoughts of making links that you have some real bad links on your machine and want to replace just those few links? If that is the case and you can't justify or spring for new chains and sprockets (ideally doing a complete rebuild of the undercarriage) currently; h...

There must be a forestry/Logging supply store near you. One we have in Maine and New Hampshire is Labonville. Their home store is in Gorham, NH and they have a website. Their on line catalog will give you pictures and the typical names and details of the gear. They will ship but I don't know how eco...

The batteries (2) called for in the parts catalog are 12 volt, BCI group 30H, having 685 CCA each (current John Deere part number TY21741). Those are top post batteries and get connected in parallel. The fact that you say it pushes good, continues to make me think your steering issues relate to adju...

Good morning. T5E3M 051875 is your crawler's serial number. I am guessing the other number you posted may have come from the tag on the loader attachment and is not used to identify the crawler. Loader ID tags during those years usually begin with a 7450 prefix designating the loader on a 450. Here ...

Welcome to the Board. You say you have a 450. Just to confirm is this a straight 450 with no letter suffix? Do you know/have the serial number? The 450s were built from 1965 to 1970. The movement when you start it may be the shifter linkage is worn and out of adjustment, not unusual. Adjustment is a...

Welcome. derf may be around but a check of his profile shows his last post was in January of 2011. It helps those reading your post if you can provide the model of your crawler (and the part number and name if you can) when you are looking for something. You can find your parts book on line at https...

Lavoy and original possum have given you good advice. Your problem may simply be an adjustment, but the problem needs to be found/diagnosed before anyone can help you with answers to correct the problem. We can't say just turn this one thing to correct your problem. Do you have Service Manual SM2028...

A 4039 will replace a 4219, I know of a 2030 wheel tractor that had a 4219 originally and has a 4039 in it now. A number of parts may need to be swapped, I won't say exactly what, but I believe in that case the original rear plate and flywheel were used. You may need to change some or all the front ...

Tmond,

Do you have the Service and the Operator's manuals for your crawler?
