Re: 350B Final Drive Gearing

Here's the conundrum: Repair the bad side and it will change the direction it pulls to, assuming the other side has at least some wear. Both sides need to have the same amount of wear. Either fix it right or put up with it. As long as you can adjust the tracks it will work for you. There should be o...

Re: 350B Final Drive Gearing

Let me make that a little clearer. Worn tracks have a greater distance between pads. When the bushi9ng gets to the sprocket it first is a little distance from the base of the tooth, but rubs its way to the base, pulling the track a little more as it rubs in. Experience talking here.

Re: 350B Final Drive Gearing

Before you break the track check your pins and bushings. Believe it or not, a track with less slop will apparently run slower than one with good slack (and eat up the sprocket doing it).

Re: 420 radiator

According to Ron O'Neill, the Tractor Doctor, in the August issue of Green Magazine, you can use muriatic acid in radiators and even in engines using thermo-siphon cooling.

Re: 2010 hydraulics not responding!

Looks like you are new to the board and possibly new to your 2010. The blade hydraulic system is separate from the transmission. If it is not responding either the hydraulic oil level is low, the pump is disengaged or has failed, or there is some other cause (which should be more obvious). But if yo...

Re: 40C track parts?

Do both sides at the same time or the dozer will walk crooked for a long time.

Re: 2010 injection pump

Assuming the injector pump is good, I would look for either an air (first) or fuel restriction.

Re: lubricating my undercarriage on my 40C

Should be a button-head fitting on the hub between the spokes. You may have to move the track several pads to see it.

Re: lubricating my undercarriage on my 40C

A 3-roller uses "heavy gun grease" in a standard grease gun. Fifteen pumps every ten hours by my book.

Re: JD 350 track loader

Heating it can ruin the seals. I have had good luck tapping with two hammers (opposite) while applying pressure on the zerk.

Re: Track adjuster grease nipple (Zerk)

That fitting is for a Caterpillar. You should see two ports on the front of the tensioner. One is a 1/4" NPT grease fitting and the other 1/2" NC "setscrew" (which has a locknut on it and a ball under it). If the fitting has 1/2" NC threads then you need to use the other one with a grease fitting. O...

Re: 450-C Injection pump and timing questions

Line up the two lines in the window you opened. This should be numbehr 1TDC . The timing pin hole should be close now.
