Cat 955L SN 85J10667 year?

pittsburgh cat man said: Sleeve being loose will definitely cause no fuel and the stuff in your pump is why they put water separator on them I’ve seen big chunks of ice inside of those pumps in the winter Click to expand... I am planning on taking this fuel pump off and taking it to a local diesel shop for repair. In the meantime, I need to get this starter fixed. It just clicks once and won't turn over. In your opinion should I just replace the entire starter or try to find a solenoid that will work?

Post a picture of bendix might be something to try if you have right one

1. Fuel tank internally for corrosion.
2. All the fuel lines. If you can’t find a water separator then maybe someone has removed it.? You really need one.
3. Fuel transfer pump.
4. Fuel injection lines & injectors. Probably the most important thing you need is a Parts Manual. That will enable you to see how things are supposed to be installed on the machine. Search for Cat Publication reference SEBP1053 which covers all machines from Serial Number 85J9510-Up.

Transfer pump is in front of pump I’m thinking some of them bolt 20 was a timing pin

I also ordered the following replacement solenoid. I'm really hoping the starter is still good. As a long shot, I'm going to try to remove the solenoid tomorrow and see if I can disassemble it and clean the contacts.

A small amount of sediment came out and then pure fuel. No water came out. I do plan on doing a better inspection of the entire tank. I do plan on adding a water separator. Clean fuel is currently flowing from the tank to the fuel pump. When using the priming pump, I am getting fuel all the way to the injector nozzles. They were removed from the machine and I thoroughly cleaned all parts before reassembly. I will check fuel pressure when I get the starter fixed. This should give me an idea of the fuel transfer pump condition. I do have all of the manuals. I downloaded them first thing.

Take the wires off take the little metal link between bendix and motor take 4 5/16 head bolts out facing wires when you get the little cover off with the 3/4 nuts on it loosen nuts till you can turn them turn them 180 degrees (they have a square on them that fits in plate) make sure the place they are burnt is toward outside inside the bendix is a round copper disc as long as it doesn’t have holes burnt thru it you can remove clip and flip it over make sure you get insulators back in the way they came off and put clip back on it it does happen to be burnt thru you will need a new one

Thank you sir! I will do this tomorrow and report back.

I got the solenoid off today and cleaned up the contact plate. I also rotated it 180 degrees. I cleaned off the contacts as well, but that was after I took the following pictures. I got everything put back together and it still does the same thing. It clicks once and then makes a whining noise if I hold the starter switch. At this point I think I burned up the starter when I was trying to get it started recently. It looks to be the original starter, so maybe it was on its last leg. By chance, does anyone know the new Cat part number for these starters? Or, is there a newer, better option?

Start off by pulling the starter out completely and take a good look at the small pinion gear for damage. Post photos. If it is damaged then the next thing to look at is the condition of the teeth on the flywheel ring gear.

This help

pittsburgh cat man said: This help Click to expand... Thanks, I didn't have any luck with those part numbers. I found an aftermarket one that should work.

Those came out of the parts book for that machine

Yes sir, I'm thinking there must be newer Cat part numbers because when I search for the older part numbers I don't see many results. Are these old starters 11 tooth or 12 tooth? I see different options coming up. I also see that some people put newer style gear reduction starters on these older machines. Any thoughts on those?

Yes sir, I understand and will pull the starter Monday when I am back with the machine. I will count the teeth at that time and report back. Meanwhile I am researching different options, such as the newer gear reduction starters, which I have been curious about for some time. Since we have part number 7S4090 from the 955L parts book, I am trying to determine if that is 11 or 12 teeth. I'm not finding any information online, and was hoping someone would know. Looking over my pictures from yesterday, I do see 1113969 stamped on the starter in the machine. It is painted yellow and looks pretty old, but I am not sure if it's original to the machine. Online searches show that 1113969 is a Delco Remy 40MT with 12 teeth, but as you stated, if not original to the machine then it's irrelevant. So, before I can get back to the machine on Monday I'm hoping someone can determine how many teeth were on the original starter with part number 7S4090.

I got the starter off today. It's a 12 tooth starter. Once it was out, I tested it and it wouldn't spin over at all. I've got it home, cleaned up, and on the bench, and I have a new solenoid that I'm going to test on it tonight or tomorrow when I get time. In the meantime, I did some more research and found a Delco Remy 39 MT 24v 12 tooth starter model 8200435. If I can't get this old starter working, I may give this newer gear reduction model a try.

Got any photos of the teeth on the ring gear.?
