Hello, as I continue to troubleshoot this problem I began to look at replacement for the large chain ring. The Crank is a shimano FC-A413.
46-36-26. I've been looking online for a suitable replacement and would appreciate any assistance. I have found what looks like a match on Ebay. It is NOS but I'm not certain it is correct. Here's the link : sorry, I'm not allowed to post URL links. I search on google for this: 46 tooth chainring bolt circle diameter 110mm, an Ebay link showed the Shimano Hyperdrive Chainring SG 46t NOS New Alloy G-46 8 Spd F-46 110mm MTB LX

I'll look into this more tomorrow. Thanks.
