Anyone know the size of the bolts that screw in to the rear of the engine (where the bellhousing goes) on a 215 engine? Also, are they fine or coarse thread?

I'm trying to put a 215 that I have on an engine stand and having problems finding the right size bolt. I don't have the bellhousing or any existing bolts from that area.

Thanks, Ilya

 

They are most likey 5/16 bolts and definitely a fine thread (5/16-24).

 

Randy is my hero but I think a bellhousing bolt is more like a 7/16

 

Sorry, Randy, but you are great on the 351 blocks. On my 223 the bolts are 7/16. You are still my hero too.

 

351s are 7/16-18

 

Sorry Randy, but now Tim's my hero!

 

See, now that's what I get for trying to help. I said "they are most likely...". Hero, my b#tt.

I should just refer you to my favorite web site: www.figureitoutyourownself.com

They are a fine thread, though, right?

no thats 7/16-24, sorry

 

One of those days, huh Randy!

 

From the Ford Parts and Accessories catalog, for a 215, after 1953, the "clutch housing to cylinder block" bolt is listed as a 7/16"-14 x 3" hex head, part number 20554-S8. There should be four of them.

 

Take all Randy's Posts away, He's got to start over.

 

14 thread count seems awfully coarse. On my 48 seems like everything is 24 thread count.

it's 7/16-18, your trucks most likely 5/16-24

 

The Parts&Accessories catalogs are like an assembly manual for these trucks and should be the gospel for details like that...so...was I looking at the wrong bolt in the manual?

 

hey randy at least you got the /16 part right! thats half right in my book
