Post by vanco » Tue Feb 03, 2026 9:16 pm

WTB: Or (Borrow One). Camshaft rear bearing reamer bar that is put through the camshaft journals to align bore the rear bearing. Just trying to rebuild my T engine the proper way. I don't have a lathe to make one, any help would be appreciated!
Thanks, John

This is mine. I have multiple standard and undersized reamers. I think these are jig bore reamers. Had it made so it can be powered by a drill motor, wrench or piece of bar stock. Cost about $250 to have it made locally. May be a little too far from you though.

Thanks for the photo's and information! To my knowledge there are not any model t ford clubs in Utah so I joined the MTFCA so that I have some information flow. Possibly I can find a machine shop in the area that would consider making one, most shops I have found do not have the time or interest in model t fords. It is all about available time and money. Thanks everyone, John

Is this tool really necessary? Does every motor re-builder use one? Does the service manual refer to this procedure?
Do you have a reasonable suspension that your block's cam mounts are out of alignment?

I'm not sure, I guess that I should do some more research? I have seen Mike Bender use one on his engine rebuilds as well as others in the past. My engine requires that a new bearing be installed.

Re - Utah Model T Club Chapters:
While I don't see any chapters listing for MTFCA or MTFCI being in Utah there was a Model T Ford Club International annual tour in 2013 out of Kanab Utah.
I did not attend or remember who put it on.
But I will guess that Model T Speedometer expert Russ Furstnow (Flagstaff, Az) is nearby and might know of Model T folks in the area.

Also see this posting
viewtopic.php?f=2&t=51412

And remember, if there is interest in the area start your own chapter!

And for my Camshaft Rear Bearing Reamer I used a nice shaft, made adapter sleeves, and an adapter to take "stock" reamers to get the job done.
I made my own.
Mike

Every engine
Rajo & Dan;
Do you perceive that The rear bushing was off some , therefore requiring this operation??
Does the lifter relief notch pull your reamer a bit?
If you were installing NOS iron bushings that fit the cam without reaming, would you still do this?

No - just seems to be a good practice being how flimsy a T camshaft is.
Not that I perceived.
Anytime a bushing is installed as a "press fit", no matter what the material the bushing is made of, reaming is prudent.
