TR4/4A Crank Bolt Size

[Geo Hahn]

Just a quick question -- what size is the head of the crank bolt on a TRactor engine?

All I recall is that it is a size I do not have in a 6-point -- I know where to borrow one but do not remember what it takes (and want it on hand before I start disassembly.

TIA.

1 1/8 I checked the one in my parts box.

Thanks... no excuse now for not getting this done.

Got an impact wrench of some sort ?

This will be to replace the front seal on the TR4 so I am hoping I can just get the radiator out of the way and sneak in there. When I did the TR3A I used a 6-point socket and a breaker bar braced against the frame -- then bumped the starter. Came loose fine. I'll try that way first.

Ya, thanks now I don't have an excuse either. Gasket has been on the bench for a couple of years.
