Sunstar U joint

Recommended Posts


I need to replace the one on the tranny side of the shaft.

Is there a way to replace it without removing the shaft? This is on an 88 Sunstar with the M16.

It is wobbling quite a bit and creating a vibration in the motor while running and shut down.

Just trying to get this mower in shape before I put it for sale and don't want to saddle anyone with a known issue...wish the guy I bought it from had the same ethics.C

It seems like when I grab it at the end of the shaft where it connects to the output shaft of the transmission the play is in there. Almost like the splines are worn or the output shaft is moving...

Should I just remove the shaft off the motor and check it out further?

If you can move driveshaft laterally gives more evidence that a cross is kaput at this point. You'll have to remove the whole driveshaft to confirm it. More then likely both cross' will have to be replaced.

That shaft is a slip fit onto the hydro input shaft if I remember correctly. All one would need to do is remove your engine mount bolts and slide the engine forward a few inches to get that shaft off the hydro input. With the tunnel cover removed, you might be able to replace the u-joint cross without taking the other end off the motor. Hopefully it was not ran this way too long to wear on the splines.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
