CAT 299D won't move

[Nige]

Would you like to post some photos of your repairs to the speed sensor wiring before I comment..?

 

[Jeffrey Bandel]

When I installed the new speed sensor it came with a Deutsch connector. My wiring repairs went bye bye.

 

[Nige]

I fixed all the wiring and it tested good.

Sorry, based on what you said here I didn't realize that the damage was on the sensor pigtail and that it was junked when you changed the sensor.

 

[Jeffrey Bandel]

I am also getting the #12 warning as well. It is amber and solid--which according to the manual is the Air Cleaner Indicator. I pulled out the air filter and it wasn't in bad shape--installed new in May so it has about 40 hours on it.

 

[Nige]

It may be the sensor wiring rather than the filter itself. Without looking I'm not sure whether that machine has an atmospheric pressure sensor on it and intake restriction (what puts the light on) is measured relative to that. You'd have to trace it via the schematic to figure out if it's a single sensor or something more complex. If the latter you basically have to go through all the wiring connections from both the APS and the intake manifold sensor right back to the ECM.

With all these potential wiring connection issues now may be the time to consider applying Senson grease & amalgamating tape over the electrical connectors, especially the critical ones. http://sensontek.com.au/

This is a stretch: I just flushed out the cooling system and put ELC/Distilled in it. After doing this, the current problem started. If the number 12 warning light goes to red it indicates high coolant temp. Right now it is amber. Any chance I have a problem there?

 

[Nige]

No harm in pulling out the coolant temp sensor and taking a look. Clean the business end of necessary but not with anything really abrasive.

I'll check it tomorrow. Today I ran it for about 30 minutes. It was fine until the 30th minute when the parking brake came on and stopped it. I turned it back on put it away.

 

[Jeffrey Bandel]

I went out to check it. I was moving it to the shop and it threw a track. Something else to learn to fix...

 

[Jeffrey Bandel]

Got the track back on. It wasn't that hard. I let all the grease pressure out, lifted it up, pulled the track a little, greased the fitting until the tension was correct, put it back down, drove it about thirty feet and the pressure was gone and it was sagging like I never greased it. Is that normal? Do I need to put more grease in?

I took this tensioner/recoil out of a 299 a few weeks back. The rod had unscrewed from the tensioner and let the spring go. If you open the plate you can see the spring and the rod, if the rod has unscrewed the track won’t tension properly.

 

[Jeffrey Bandel]

Great picture. Thanks.

 

[Jeffrey Bandel]

Can you get the whole assembly out of the grease access panel?

When adjusting track tension especially when you released the tension. You will pump it up and then travel forward a few feet. Then check your tension again and adjust accordingly.

Not uncommon. It's hard to get a track tensioned correctly at the first attempt. Usually you have to tension, move back and forward a couple of yards in a straight line, and re-tension. Repeat as many times as necessary until the track sag is in the specified range.

Think we posted at the same time. Have you tightened the valve since letting the grease out?

No. With the track off you draw it out of the front of the frame.

 

[Jeffrey Bandel]

Great guys. This helps a ton. I'll try pumping her up again tomorrow morning.

 

[ih100]

Be aware, the scenario I showed above isn’t uncommon on these machines. Did you have a job to get the track off? If you did, check the rod as I said, and definitely get hold of the recoil mechanism rework instruction from SIS. Nige will probably be able to help with this.

 

[Jeffrey Bandel]

I didn't take the track off. It slipped off the back. I just put it back on.
