A friend and I each picked up early 90's Tundras lately. I have heard some talk about the oil pump gears failing with age.
What do you sled gurus know about that?
I have heard the screws back out and cause the gears to lose their mesh a strip out, also the key for the gear may be plastic?
Since these sleds are new to us and have had some use, I was thinking about replacing the gears and keys, any insights, tips, part numbers, would be helpful...
