I have a Raptor 60 with a 70 in it and I think it might be time to change the starter bearings. When I try to start it it makes a screeching noise. Some times it spins fine no problem. Some times it just spins and doesn't seem to turn the engine over. Any one know what to look for to tell you when it's time to replace the bearings? Also would this be a good time to put a new clutch liner in? Yes I have checked the collar at the tom and the set screws are tight.

yep its time to change em...mine would "creak" on start up then quiet down after a bit they started full time and once I changed them I figured out why they went bad so fast in the first place...(heli was less than a gallon old) the start shaft coupler was not true and centered on the shaft, It was on the right flat spots but no matter what it would woble which took the bearings out prematurly....so check that also. if it spins and dosent turn the engine over thats your one way bearing and it need changed (I've never had one of those go bad)

Thanks for the help. I hadn't thought of the one way bearing I guess I should check that also. Have you ever change the clutch liner. If so how do you get the old one out to put in the new?

if its never been changed before I use a little heat to get the glue to separate the clutch liner....and pull it out with a pair of needle nose plyers...clean up the inside of the bell with some sand paper and fit your new clutch liner in there, attach your clutch shoes to your fan and wrap one wrap of electrical tape around the shoe, put a thin layer of JB weld on the liner, fit in the bell and then put the wrapped shoe in the bell to hold the liner true while its drying
