Grease gun fittings

You probably are looking for what I was always told was a "giant" button head fitting. The regular size, which you have is 5/8 and you nmeed 7/8 See the Mcmaster site I have attached

If you had right size that type would work but JD made smaller button heads the Cat so you need the Cat size. Next you need to have a Allimite track grease pump that is high volune low presure a reg. grease gun unless your very careful will blowout the seals which many are already don, then you need to use roller grease, that is like a very very heavy oil and runs about like honey.
The wheel is called the front idler

Thanks, via google I've found a UK based supplier that advertises giant button (7/8th) size so all being well I'll buy one tomorrow. I'll get the right lubricant too, I know what it is as the automatic chassis lubricator on my tractor unit (semi-rig in US?) uses the stuff - it's like oily gloop.

Now all I need to do is improvise a way of filling the things with oil and not overpressurise and pop the seals. Maybe I could use a syringe type devise?

I changed the final drives and gearbox oils today. Also I removed the ''wading plugs'' from the brake housing compartments and got at least three gallons of mucky oily water out of one - I got soaked😞😞 I removed the square plates at the back and the large inspection plate by the seat. I guess the brakes and clutches will work better when they dry out and are no longer under water!

Just a quick question, while changing the starter pinion housing oil I discovered a zerk fitting beneath the left hand pony motor cylinder. It was a vertical fitting and so impossible to get the gun on. I changed it for a 90 degree fitting and gave it some shots of grease (guessing this was a good thing!) Moving back now behind the bullhead the floor board there has a little bulge in it to accommodate the starter drive with a small 1/2" hole in this bulge. I dug around in there expecting to find another zerk fitting but just found a small set-screw. Should there be a zerk fitting there or not?

Thanks Julian.

You should really get a Opperaters manual it has big triple page foldout that has all the lube points and how often you should use them and what lubes to use. There are 4 throwout bearings on the tractor and a bunch of main clutch and steering clutch levers & componits along with a buch of undercarriage parts,water pump,ect. and all take diff amounts at diff hours of use. and there are a bunch of compartments on the tractor that have to be kept full of lubes also Get on EBay or add for one in our buy and sell sections here, so you dont find out the hard way that you missed any. Also under the tractor there are 3 drain holes that you need to make sure are kept open so seal leakage wount reach the 3 clutch mechs.

Thanks Willie, I've been looking on ebay every day now for a while. I have someone close to me who can let me copy/borrow some manuals as an interim solution but I will get my own at some stage.

There's non available now I'm looking, as soon as I have one there's will be another 10 on ebay the next day (all cheaper and better condition) 😞

try this place they may have 1 http://stores.ebay.com/JT-MANUAL-SUPPLY Not all his stuff is listed you may want to EMail him and ask if hes got 1

The other drain plug is in the main clutch housing. It can accumulate oil from the engine and transmission as well as water.

Another hidden grease fitting is on the main clutch pilot bearing. Grease fitting is on the rear face at the outer edge of the flywheel. Doesn't take a lot of grease, just a couple shots very infrequently. Too much will get into the clutch and make it "sticky". You'll have to take off the clutch adjustment cover to see that one.
