Greetings!! So another resent post made me think before something bad happens…. How do you check the clutch oil? Can’t seem to find a location in the service book. Was thinking about this and don’t want to be putting a new clutch in it. Also I pretty sure it needs it adjusted but not sure on specs.
You have a 1958 3U; 75hp gas start, 19880lbs, D315 the clutch oil humm from my 57; 955C 12A Traxcavator you may need to pull the top plate off and look. I do know my 12A used 4 gallons... I'm thinking 30W but don't hold me to that. I don't have a 3U manual hut have you tried ACMOC? A set of manuals are invaluable and can be purchased from eBay or Jenkins.
Ok broke out my library on 57-60 12A there is a dipstick on the top plate on the clutch housing close to the pulley on the starter motor. you may need to remove a floor panel.
Thanks Dan, I have a pdf of the service manual, parts catalog, and a d315 service manual. It’s no longer a pony start because I put electric start on it… The pony did run but not very good and than the mag gear stripped. Very sad moment…
I wonder if Cat ever had a turbo on the d315? Was looking at it and it looks like a turbo would bolt on…
Early S/N 112 graders used a dry cutch. I worked on one several years ago and got parts from General Gear in Boise ID. John was a tremendous help with that. 800 531 9021 and they have a web page if you Google them. Free play adjustment may be all you need. PM me if you have any questions
What does it take to put glow plugs in? I’m going to be resealing the injectors and was just thinking about them for cold starting…
On the surface it looks like a simple parts change: the glow plugs themselve and pre-combustion chambers to accept them. Add a power source and you would be all set. I’m equally sure that it isn’t that simple; but your parts book should be a guide. ACMOC should have some discussions about doing just that, and General Gear probably can provide the parts. The guy that I did the clutch work for had me add an electric solenoid operated ether injection setup off a junked JD544 loader, but boy, is that touchy! Push button operated, all you have to do is poke the button and you wake that ether bunny up with a bang. He’s already popped the top off one PC chamber that I had to have tig welded back together. I don’t recommend that route.
Tank style block heater would be better if you have power nearby. Shelter helps a lot, too.
That’s the problem, I don’t want to drive 13 miles to plug it in. I’m going to fields with it and leave it out there so there’s no power to plug it in. I don’t really like ether because of that… It’s a higher hour grader so I don’t want to stress it too much with ether.
You could carry a generator in your crummy and just head out early, plug ithe heater in and grease up; fuel up; and listen to the news for an hour I am sure that glow plugs can be added. call John at General Gear and sound him out.The Generator, battery charger, and a block heater, along with an old horse blanket to keep the heat in might save the day, though.
That's a late enough s/n to have the head that accommodates the larger diameter pre-combustion chambers required for glow plugs. Straight forward addition once you round up the parts. Turbo's were available for the D315 but that's asking a lot for tired engines.
Your Probably right about the turbo, I have a thing with listening to turbos whistling lol… Reason I brought up injectors and glow plugs is I have 2 injectors leaking engine oil? I didn’t know they have oil up there. So I was figuring if I need to replace them I might as well go with glow plugs too..
You don’t have injectors as per se, you have replaceable spray nozzles, probably just need new o rings. The injection pumps do the work, pet peeve of mine,cheers
I’d like to check them also anyway if it’s not too bad to check… So I noticed that going down a hill in high gear (when the engine is holding it back) that it will blow a grayish smoke and start missing a bit, now is that normal or what do I need to look at? If I’m going to have the injectors out how do I check them? I have a part number of 9F5937 for the tips with O-ring, does that sound right?
