    Alignment of 951 white motor problems with tool !!

    Ok guys I messed with this thing for over a hour shimming it to find out the SBT tool I got the actual shaft is bigger then the female splines of the white motor I measured it and I got .6819 tho and the tool is .70035 tho. I called sbt and they tell me the white motor is rare and that's problem why ?? This does not make sense to me.

    I can only get the tool in about 1/2" and binds up. Is my sbt tool machined wrong possibly ?

    possjble, I had the same problem with my first sbt tool. It was too large to fit into the pto. Drove me nuts for a few days. I made a polite complaint and got it replaced.

    The thing is all the adapters fit onto the sbt alignment shaft.

    My 951 uses only the shaft. No aligment adapter!

    I read something a while back about some sbt alignment tools being out of spec.

    xp models need the adapter. My first sbt tool was dinged in shipmemt...just enough to prevent entry to the pto. Insist on a replacement. Tqlk to jerry in [email protected] Be nice or be prepared to have to make a claim against the shipper

    Well guys called SBT and pretty much the tech was no help. I asked him for some measurements of the shaft and he could not help me. So I measured it again and same measurements. Now I got bored and took a 12mm 1/2" deep socket and put it in the pto coupling and it was a supper snug fit so I measured it and it came out to the same measurement as the sbt tool. I was like What the hell, so I tried to put it back in and no success so I measured the shaft again in a few spots and boom I figured it out. About 1/4" from the tip the shaft was thicker by a few thou so I took some fine emery cloth and spun it around for a bit and boom it fit into my PTO coupling.

    If anyone else has this prob measure the shaft in a few spots . Mine had no signs of being dropped either.

    This maybe my issue. I have a 95 spx I'm trying to align. i can push the Alignment tool into the fly wheel and once it gets to the flywheel it will go in but take a little force. I can do it by pushing with just a couple fingers. once im about 1/2" before max depth it gets harder to push but it does go in. i tried adjusting just the front incase my block was crooked but cant seem to make it go smooth no matter what I do I tried pushing the engine all around with the mounts loose and only makes it worse. I think where the alignment tool tappers wide is where the Carbon seal is and that is what I am feeling for the last little bit.

    how easy should this slide in? it does not slide freely but does appear to go right in without hitting the edge of the flywheel. How precise does the need to be? I am going to measure the tool and the flywheel to see the sizing. I imagine the drive shaft is smaller diameter than the alignment tool so I may be at an ok spot.

    any recommendations?

    No such thing as quality control these days.
