    It came with the shifter. I was told that it would not. Oh well. No biggie. I’ve got an extra one now.

    Looks pretty clean. Donor truck was only at 8k miles. Lived in PNW area. Shipped to me out of Seattle.

    Not just yet. Still waiting on Tilton for my hydro unit. That, and I’m waiting for a couple of pieces I need for my lathe so that I can machine the spacers for the throw out bearing.

    One cool thing on this trans is the neutral position indicator switch on the shifter housing. The RA trans didn’t have that.
    I could use that for an added level of safety for a remote start system.

    Bell housing to engine bolt pattern confirmed. They’re the same. That was the first thing I checked.

    I did not receive the mount. So, I’ve ordered one of those.

    21 spline, 29.X mm in diameter. Begging for a pilot bearing!

    Looks like it’d be pretty easy to do.

    Thank you.

    What’s the overall length of that RA trans?

    Edit: I measured mine while I had daylight today. It’s 27” long.

    I wonder if that switch is for reverse or neutral?

    BU switch is on the other side. This one is definitely neutral position.

    @Spankerton Might be able to help you out. That’s his transmission.

    Very easy, a piece of readily available 12mm 4140, just need to determine diameter for press fit, length and how deep to drill the input shaft. Obviously, needs to be a very accurate hole. I have a 3' 4140 bar, if you want a piece? Bearing is Toyota 90363-12002, which is a standard rs6201 bearing, the flywheel should be ready to accept the bearing, the unit on my truck is.

    I’m looking at the bearing. Seems simple enough.

    If we made some sort of drill guide that slips over the splines maybe? Otherwise, I wouldn’t try drilling that shaft unless it was out of the trans. It’s got to be tough material too. Gonna be fun to drill.

    Well kids. I have run into a minor hiccup.

    The new RC transmission is pretty much exactly 28" long. The outgoing RA trans is 27" long.

    Not the end of the world. But, It does mean that I'll be doing drive shaft modifications. Will need to shorten the rear shaft by 1” as well as lengthen the front shaft by 1”. I’m considering just using a 1” spacer for the front shaft.

    Can I ask a question regarding the pilot bearing, it's come up in this thread as well as @Jowett's thread as well, what problem are you trying to fix by adding a pilot bearing, and how will a pilot bearing fix said problem?

    I mean, it can certainly be added without too much trouble, but to what end?

    Jeff

    Just hypotheses at this point... short answers.... first, we can improve shift quality and synchronizer wear due to less clutch drag. Second, we can increase the strength of the transmission and reduce wear on several other parts.

    Please feel free to argue against any or all of this!.... We may experience some clutch drag during disengagement, not enough to cause grinding right away, but enough to place extra wear on those synchronizers. The bending moment created by the clutch disc on the input shaft has got to be impressive. On the Taco, the disc is 275mm/10.8" in diameter and weighs over 4lbs. With the clutch disengaged at 6k RPM, even momentarily during a shift, it's floating out there in single shear. Is it moving and creating extra drag? Being in single shear out there could even create a radial vibration. A pilot bearing should quell or eliminate the issue.

    As many are aware, when under power, the input shaft/gears and counter shaft/gears are attempting to push apart. This causes the unique long input and counter shaft to bend in the middle. The input shaft bearing then becomes a fulcrum... the input shaft and clutch splines are then loaded and forced in the opposite direction of which the gears are being forced. The clutch disc may be captured and engaged, but the hub with all of the sprung parts is seeing loads in a direction for which it is not meant. A pilot bearing will add considerable support, help prevent bending, and reduce loads on bearings.

    I had not considered the high RPM shifting vibes. I suppose if the disc was way out of balance, It'd help. I was always under the impression that the pilot helped to fight clutch chatter by keeping the disc from moving in any sort of orbital fashion.

    Performed correctly, adding the bearing can only help things. If you have the means, by all means, add it. I've actually already designed the drill guide to do it in my head. Would be fairly simple utilizing the 90363-12002 bearings as the actual bit guides installed in a spline-centric tube/sleeve.

    At this point. With my truck, I'm going to have to consider this modification on the next go-around. I need to get this thing back on the road. I've already got PLENTY on my plate getting this trans to work in my truck. The driveshaft thing is a bit of a bummer. But, such is the way of vehicle customizing. Yay.

    Yes, that is some the movement/deflection that we should be concerned about. I see the potential for some real gains by adding the pilot bearing.
