Hi,
I am rebuilding a 1994 1KZ-TE. The idle gear no1 and the shaft are worn and need to be replaced. There was no problem getting the gear but the I cant find the original shaft part number 1358167040. The only part available is 1358167041but it is different than the original and does not fit into the block. I've read there were issues with this part in the early engines and it was redesigned. The new part does have larger oil holes and larger bolts.
What are my options? Surely there is something I can do. Do I drill out the block approximately 4mm deep to accomadate the new part.
Any tips?
Thanks
