What constitutes a groove?
I have attached a pic of a saginaw 3 speed replacement transmission going into my son's 1970 C-10 stepside. I've found all the sites that talk about grooves on the input shaft. I'm trying to determine if this is wear on the front bearing retainer or are these markings the allusive grooves mentioned in other tranny id articles. No one has ever posted a pic of a one groove, 2 groove, 3 groove, etc. trans so I don't know what to look for.
Thanks. Last edited by My70C10; 08-07-2007 at 06:12 PM. Reason: Forgot picture...go figure. |

Scroll down until you see the input shaft.. I don't know if all saginaws have the grooves though. I don't remember if mine had them but then I don't think I even looked... |

Re: What constitutes a groove?
Thanks 68gmsee...I appreciate the info...now if I could get confirmation that what I'm seeing on the front bearing retainer is normal or excessive wear. The difference between the snout diameter and the what looks like worn area is about 1/100 of an inch and does not go completely around the diameter of the front bearing retainer. I do have the option of swapping the one from the previous transmission if this is excessive wear.
Thanks. |

Re: What constitutes a groove?
Looks like wear from the throw out bearing to me.However I'm not an expert and I have no idea how much is too much.
This should TTT for you and maybe someone with real knowledge will give you better info.

Re: What constitutes a groove?
Re: throw out bearing. That's what I was thinking also.. I suspect the problem would be occasional sticking of the clutch. More than likely someone drove it with a bad throw out bearing and it was spinning on the shaft.
I'd go visit some junkyards. Take the part with you to make sure you get the right one. |
