Hello all, I bought a HD5G a while back, havent really done much with it until now, Im sort of new around these older track machines and I have a dumb question to ask, where are the grease fittings located on the idler wheels? thank you in advance for the help.

They do not use grease , they use oil in the rollers and idlers , they use timken cone and cup bearings in all parts . also in the rear axle to truck frame bearing , that one is a link belt spherical roller bearing - 2 part each on inner and outer (4 pcs).

In the center of the axle is a plug / remove this and use a OIL gun with tube to reach inside and then pump oil into cavity until it runs out around fill tube , then re-install the plug . A light semi-grease has been used by some in this area like a #000 0r #0000 fluid grease.

The outboard axle bearing on early machines was oiled through rifle drilled axle and a few other fittings like steering clutch throw out bearing and flywheel pilot bearing were lubes by felt wick and tub arrangement , most have been converted to gun grease, and in flywheel plugging crank shaft hole and putting in sealed ball bearing for pilot.

thankyou very much for the insight, thought I was going nuts not being able to find any grease fittings under that thing.
