SIII Transmission - Distance piece install

[Tim Smith]

Before moving full steam ahead here, I wanted to check the forum and see if there is a correct way to install the updated distance piece on a series 3 suffix B transmission. The new distance piece is two parts rather than the original single part.

Should the hat go on the main shaft first followed by the sleeve or is it the other way around?

Part 24 here:

Since this will be the first of many transmission rebuilds I will likely be doing soon, I figure it's best to start off on the right foot.

Tim, that's a weak spot of S3 boxes, albeit the suffix B is much better. If it were me, I'd go with the original one piece. George has them.

Thanks Terrys but I'm not waiting. I need to have this box done and installed for a run to MAR and then National Rally. I'm really not treating this as a rebuild but rather a fix it and run it situation. This truck is getting long in the tooth and should go offline this winter. In that time I'll likely rebuild another box completely and have it on stand by if it's needed.

Below is the new part VS the old shot. It's pretty obvious which is which. I'm just not sure if the hat piece should go on the main shaft first and point toward the output end or if the sleeve side should go on first and then have the hat side pointing toward the input side.

Tim, I believe the hat faces the output. As pictured input on the right output on the left.

Thanks! So as I'm stacking the gears starting with the output end first, I will put the sleeve on and then the hat to finish at the input side.

Got it. Thanks again.

IMHO if you want a bullet proof fix on the SII or SIII clean the shaft with acetone and during assembly cement on the bushing(s) to the shaft with red locktight. This prevents them from ever breaking. If you ever need to remove a small lathe is needed. Ray

there is only one way it can fit as there is a pin that locks it to the mainshaft. Definitely use the two piece design. The one piece units are prone to breakage hence the change.

[Tim Smith]

The broken piece does have a lot more wiggle room on the main shaft than the new pieces. I presumed it was through typical wear but maybe that gapping was what made it break. The new pieces are a little tight so that makes me think Ray's idea is on the right track.

This is what my break looked like:
