Model T Ford Forum: Forum 2015: Crank/Flange access

Gents,

Total Newb question…they say the only dumb question is the one not asked….

So I have not taken apart a T motor in 35 years…
I cannot figure out how to remove the 4 bolts that hold the Flywheel to the crank flange?

This motor has an A bottom end and access with anything short of an open end on the four flange bolts is very limited. I even loosed the rear main cap but cannot remove it because the flywheel magnets are in the way

I don't recall my old stock T project from 30 years ago having an access issue with this. I assume it is because of the A mod.

Any suggestions or tips for removing them is appreciated.

Get a "low cost" china 11/16" ? wrench and bend it to fit in behind the bearing cap.

I am in the middle of this issue on my rebuild (26 Tudor) The only way I can get them off is to move the crank around so that one bolt is in the middle between the crank main and the side of the block. If you get it just in the right position, you should be able to put an 11/16 socket on it using a 3/8" socket and an extension. (At least it worked for me) I would then move the crank again until the next bolt was in position and so forth.

Joel. I took the socket and thinned it up in my lathe.

He is using the larger main caps for the Model A (A mod)crank and may not be able to get socket even if it's ground down or not in there. 11/16 bent open end wrench or an original might be his only option unless someone else that has done the conversion chimes in with a better idea.

Mark has the right idea. The thick rear main cap will further restrict access to an already tight area. Once that cap is off, I would be grinding a relief in it so that a socket or ring spanner can be used. I have a specially bent ring spanner to access those bolts. Even with that, The flywheel has to be turned and the bolts removed one at a time, with the bolt at 12 o'clock.

Hope this helps.

Allan from down under.

Ring Spanner - is that the same as a Box End Wrench?

Can you get a universal joint socket to fit on the bolts?

This post has hints on making a special wrench for those bolts.

Mark, what you show clearly has rings on the end. They look nothing like any box I have seen.

Allan, with tongue in cheek, down under,

K Barrier turned our "Magneto University" group on to the Blackhawk 4422 wrench that made the bolt removal easy. You must simply rotate the flywheel so that the wrench/bolt will clear the main bearing assy.

Allan, I agree, the down under name for the tool is more descriptive. :-)

Here's what Wikipedia has to say about wrenches (spanners):

That Blackhawk wrench must be discontinued as I had trouble finding it. But I just scored an original 5z210 wrench for $20 shipped off of T-Bay.

I will still keep an eye out for the Blackhawk though.

the original Ford tool works very well. I have a good selection of tools and I could not find a single one to do the job well. Looked through my original Ford wenches and found one that fits perfect and does the job first rate :-)
