    rear drive shaft install question

    I'm trying to install Traxxas #7150 on my 1/16 summit with a broken rear half shaft. Any idea how to get this on over the pin? The exploded views don't really show much other than that is where it goes.

    Thanks!
    Scott

    I think there is a set screw that holds the pin in. If there is; loosen the set screw, remove the pin, line up the axle, slide pin back in, tighten set screw.

    But I think the 7150 will not work with the Summit "stub"... it is a Revo half shaft.
    Whatever it is I just said... I could be wrong.

    that won't work because it wont rotate right and you will probably just break the pin because that is what commonly breaks on the 1 16 summit shafts.

    Ok, I'll take off the rest and check for the set screw. My plan was to replace the left and right shafts with merv parts to go along with my p2 rockers + merv rods. Those drive shafts won't be long enough?

    Those driveshafts will be fine. Your problem is you need the Merv yoke to connect it to the differential. You cannot connect a Merv shaft to a summit yoke since the pins to small. I'll snap a pic and show you what you'll need in a min.

    I use a heat gun to warm the plastic and it goes right on!
    A hair dryer would work just as well and is probably safer ti the plastic
    There are lots of ways to do that. Most are wrong.

    This is the difference between the two shafts. Merv on the left, Summit on the right.


    You need these two pieces to use the Merv shaft correctly.

    Great, thanks. Based on that. I think i'm just gonna go with #7151 which has both the shafts and yokes already connected in order to save some time.

    That will work... and you can use the 7150's as spares.
