  • Sweep drive shaft

    Ok, the bearings for the sweep drive shaft on one of our lanes are going.... Havent really looked at the book yet, but it LOOKS pretty straight foreword to remove/replace.... since our cams are bent to heck anyway (no clue how) I'm planning on fixing this tomorrow, how hard/how long should this be/take. And what snags will I run into? Also, any tips for setting up the cams would be great [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img]

    Re: Sweep drive shaft

    Adam I'ts not nearly as involved as replacing the table shaft. the only snag you may run into is getting the shaft out of the motor, depending on how long since they were lubed. Put your sweep to guard position, remove short link from crank arm, once bolt comes out sweep will coast to 5 pin spot. Now locate set screw in locking collar of bearing,loosen set screw, there is a hole near set screw for a center punch tap the collar towards the back of machine. Now loosen cams, take a crow bar,wedge between frame and crank arm and pry the shaft out. Just reverse steps for installation. Option: before you start look where clamp studs are in relation to lane with sweep in up position, that will be a good starting position for your cams after reinstallation. Have fun! Please lube your splines with anti-seize lubricant.(Permatex)

      Re: Sweep drive shaft

      I actually forgot what the question was. Actually just to change the bearings you need to remove short link from crank arm, remove crank arm, remove key, loosen collar on bearing, remove bearing housing bolts and remove bearing, who knows the shaft may come too. Or if you take the shaft out you don't have to remove the bearing housing, the bearing will slide out. I believe my info is accurate, It's late and im tired. Bye! :p

        Taking the entire shaft and bearing out and removing the cams and bearing assembly on the bench is a lot easier. I even take the gear motor off first because it's a lot easier to clean out the spines in the output shaft.

        As for resetting the cams.... as long as you don't touch the switch assembly you can get real close by first cranking the sweep to zero to set the SA and then crank it down to 66 and set the SB. Make sure the gaps in the switch levers are adjusted right and then run a few test cycles to fine tune the cam switches.

            Be sure to file any blemishes or things will get stuck while you’re trying to take them off the shaft. The most common places for these are at the clamp stud &amp; around key slots. Depending on if the crank arm has ever been loose, you might find some there too.
