Re: no third gear
Check the bushings at both ends of the linkage. Is there slop in the arm on the side cover? You may have to take the side cover off and check the detents. I believe your problem is probably in the linkage or adjustments somewhere. Also check the parts that are on the top of the steering mast jacket down by the gears.

Re: no third gear
Disconnect the rods at the transmission then make sure both arms on the transmission are in the middle or neutral position then try to move the front arm down or towards the rear into the 3rd gear position.

Re: no third gear
It could be a synchroniser problem. The early style hub detents can have a spring or a ball problem unless it has the detent plates and spring rings like the late types.

Re: no third gear
Pay close attention to the condition of the caged-roller bearings in the cluster and between the main-shaft and input shaft. Good used ones are better than any of the repop ones that I've seen. The repop ones are usually not hardened in the 'cage ends' - which causes them to wear out rather quickly.
Also, it is super important for the mainshaft to not be worn on the bearing snout and for the stack-up endplay on the mainshaft (2nd gear, synchro hub, etc) to be as close to .003 - .004 as possible. I usually have to monkey with the thrust washers to get the correct dimension. Another area to really pay attention to is the cluster shaft - all the repop ones are not correctly hardened (poor material) and are .001 too small. If yours is good - reuse it. If it is worn on one side, then flip it over when you reassemble the trans. |

Re: no third gear
Thanks I will tear the one down that was in the 40 when I got it.Talked to Mac today and he said tear it down before ordering parts to see if the case is good enough to use.
