So, I am icking up a used T-maxx tonight from a friend. The only thing it needs to run is a one way bearing for the starter. He upgraded the Engine to a 2.5, I cant seem to get ahold of him and I wanted to get the bearing b4 I p[icked the truck up as I am heading to the Hoby Store right away. Will it be the same bearing from the Origional engine? Or am I way off?

The Pro.15 and the 2.5r use different OWB's. They also use a different ez-start motor system. The ez-start controler works both though.
Is that what you needed to know?

By the way, the 2.5r screams in the old pro.15 version.

To be honest with you Dave, all he told me is the One-Way bearing for the 2.5 is shot, and needs to be cleaned after each start, so I should pick one up. Im heading to the Hobby store right now before I get the truck so I was hoping to pick one up. But I know nothing about this. I know my Evader inside out, but this is new to me, maybe I should just wait..lol

If he already did the upgrade and had it running then all you need is a 2.5r OWB.
They are easy enough to replace, four screws hold the motor in and the throttle linkage, ez-start wires & fuel line, of course. Then four screws take the ez-start off, then the old bearing just slips off the shaft. My only tip is to be sure you note which way the old OWB grabs/freewheels so you get the new one on right. If memory serves the OWB's are not marked to distingush directions. Go ahead and pick it up, they're fun trucks.
