Special Cam Bolt Wrench

[Fullraceflathead]

I picked up this wrench the other day at a steam engine show because the curiosity got the better of me.
I’m wondering if this fits the special Cam Bolt on the Model A engine. I don’t have an engine with the front cover off to check it. I really don’t feel like tearing into one of my spare engines.
Does anybody know the dimensions of the special Cam Bolt?
This wrench is 1.630 across the flats which tells me it’s probably for 1 5/8”spacing across the flats. The diameter is 1.920.
I don’t see any markings stamped or forged into this wrench.

i don't think its big enough. here ya go. check.

i don't know if there is different sizes of cam nuts tho.

 

[J Franklin]

From the looks of many cam nuts I have seen, I always thought the original tool was a chisel!

Old ugly thanks for those dimensions I may at some point machine the wrench I have to those larger dimensions!!!

 

[Jim Brierley]

The wrench has to be slightly 'dished' to clear the gear.

Thank you Jim so once I machine it to the proper size I'll heat it up and bend an angle to it so it clears the cam gear!!!

i wonder if it could be for Model T

just thinking out loud ive never worked on one.

 

[Fullraceflathead]

It's possible it could be for a model T. I don't have any model T. stuff at all to check it to.

 

[midgetracer]

I am quite certain that Model T had a hex nut holding the timing gear.

Looks like not.
