How do you grease the lower idlers 350c

[sullyt28]

I bought the 5/8 fitting which slides over the button fitting on the front idler and middle roller which worked great. Not a chance it will slide over the fittings on the bottom rollers. The grease fitting is not sitting proud enough to slide the grease fitting over it. Anyone know if there is a special fitting or a trick to greasing the lower rollers ?

[jtrichard]

some of the gun fittings are to big to fit some of the rollers you might be able to grind some off the edges of the fitting to make it fit.... just so you know the rollers don't take regular grease if your seals are good they take 140 wt gear oil if your seals are bad use corn head grease .... if you seals are good it takes a special gun (low pressure) to fill them with

On the low pressure gun does anyone know what pressure they put out? I was thinking about plumbing a pressure gauge in the hose of a regular gun.

[jtrichard]

it is 1800 psi but it is not the pressure it is the fact that you can FEEL when the rollers are full with a reg. grease gun you cant FEEL it and they dont hold oil very well. the roller seals wont take more than a few psi. i would bet so a gauge on a reg. gun wont do you any good ..... i have one of the alemite guns (4035) and it works great http://www.alemite.com/catalog/details. ... ns_special http://www.finditparts.com/t/4003/manuf ... emite-4035

Thanks jtrichard for the info, I think I'll get me one I need it, so you just fill yours until you fill alittle resistance on the gun?

Does anyone have a part number for this button fitting that would help avoid me potentially damaging the current one I have? It was hard enough finding this one. I was told by a few people in the industry that a lightweight grease is sufficient and feel for the slightest resistance to know when to stop. For the amount I use this machine I'm not overly concerned.

However I will look into doing as you suggested for the bottom rollers as they are untouched. I don't understand why the button heads are so much shallower on the bottom rollers ? Looking at the poor condition of fittings I think it will be difficult to slide anything under the head of the fitting.

you might want to get new buttons napa and others can get them.... the connector is the type that pushes on they make ones that pull on and that may be part of your problem here is one that pushes on .... http://www.ebay.com/itm/Lincoln-81458-B ... 19&vxp=mtr the corn head grease is about the best hard grease to use ...JD used to have "roller" grease it had the consistency of Vaseline very light light grease ..you need light grease because the speed the rollers turn... not fast enough to make heavy grease "flow" (for lack of a better word) into the bushings well

Do you put the corn oil grease into the gun then, or, will it accept the grease cartridges as well? I need to check my rollers as well and I would like to have the correct tool for the job.

[jtrichard]

the oil type gun will NOT take cartridges it has a tight seal in the tube that wont go in the cartridge i am not sure that the oil/low pressure gun will work with corn head grease ( maybe some of the others here have used corn head in a low pressure gun???) i use 140WT in mine and it works great but your seals on the rollers have to be in good shape

YES it is subtle but you can feel it

Still trying to determine if I have a unique situation. The female button fittings on the front idler and middle upper roller are different from the button fittings on the bottom rollers. The bottom roller female fittings sit just slightly proud, not nearly enough to slide the jd button grease adapter over top. I'm thinking of drilling out the centers and putting grease fittings into them otherwise i'll have to shave the jd grease adapter down to nearly nothing in an effort to get it to slide on. Not confident that will work. Not sure what other options I have.

Anyone have a similar situation ?

Thanks for all the feedback.

That's what I needed to know, thanks

Something is odd, with the proper zerks, and the proper end, it will work. I stock both.
One catch, on the upper idler, most of the old style ends are designed not to fit unless you pull out one of the cover bolts. This acts as the pressure relief so you don't blow lock up the idler.
Deere used to spec 140wt, then in later years came out with Track and Roller Grease. It is obsolete now, but the closest equivalent from Deere is Corn Heard Grease. Track and Roller grease is still available from oil jobbers, but usually in 120# drums, so not much use to most of us.
