That short pipe has rings on it like piston rings to seal the loss of gas, doesn't matter much unless it is annoying you.

I think the bar in a 3/8" or 1/4" socket set will undo the plugs out of your idlers.

Maintenance free or lubed for life rollers have the plugs.

The old joke is they are lubed for life, so when the lube runs out, that's the end of their life. You can add 30 wt drive train oil if you have some seeping and perhaps extend the life. If you want to get set up to lube these there is a special nozzle to stick in the roller that fills them to the proper level. Or you can simply add some and hope for the best.

can one screw a button head in a leaky sealed roller and use the old volume pump to keep them going

All manor of threads are used on the sealed rollers,so the chance of a button head fitting are slim.I have taken a plug from junk roller and drilled it and welded a pipe nipple on and used that to add grease.The roller has lasted much better than I ever thought it would.The first roller I saw looking wet lasted less than 100 hour without oil(planting season on a farm Cat yes the stitch in time saves time ),so the next I added grease right away and the change it latter.Well later has never happened and roller is still good,but that machine has sat 3 or 4 years awaiting transmission work.I keep finding other machines that are headed for scrape if I don't rescue them that are easier fixes than my old favorite.

Hi Wacuda. If you are talking about exhaust elbow, it bolts to a pedestal on the exhaust manifold with 4@ 3/8" bolts about 1 1/4" long. On my 47A I have caught mine coming loose, but not to the point where exhaust was leaking.

no this is a short piece of pipe between turbo & ex elbow..it has slots in it like it was supposed to have some type of clamp..
