Hey guys. Is this shaft play normal? Less than 1/8 inch in any direction.

 
No it shouldn't, I've never messed with the insides of an ax15, But most manuals are pretty similar. From that play the Imput bearing probably needs to be replaced. If you do it, go ahead and do a total rebuild.

Thanks. Others are saying similar. Generally consensus from other replies is that it is not "abnormal". Its a very low mileage 2000 ax15, so ill run it until it tanks and then either rebuild or go nv3500
 
Every manual I've ever had loose has been like that, though in an ideal world it wouldn't be. In the diagram below, on the input shaft, surface (1) is supported by bearing (2) which is held at the front of the case. On the output shaft, surface (3) is supported by bearing (4) which engages in the back of the input shaft. Because of the connection between the input and output, any clearance between the bearing and surfaces results in movement, which you see at the front of the input shaft. Once the transmission is installed in the engine, the front tip of the input shaft (5) is engaged in the pilot bearing at the back of the crank, basically eliminating that slop, and stiffening up the assembly.

Looks normal to me, as this is entire purpose of the pilot bushing in the end of the crank.

The input can't be without play otherwise would bind on installation with pilot bushing.

That's what I was thinking.
