Crank Pully Nut - b6319a
Got an "8BA" Truck Engine, want to check the torque on the "Crank Pully Nut" ( appears the pully is loose), I understand the torque is 45 ~ 55 ft lbs, I read on one site it's an 1 3/8" socket, that appears incorrect as my 1 1/4" is to big & 1 1/8" is to small, I'm assuming it's 1 3/16" but before I start hunting for one I thought I would confirm, with my luck it's some special size that Ford made a tool for :-) Thanks in advance, see picture as reference to what I need socket size for.

Ahh just realized I will need a deep socket 1 3/8, the 1 1/4 I tried cleared the cogs, not the nut - duh ! My bad, thanks for confirmation, clearance to radiator is tight, so I'm going at this blind. Thanks again.

Tighten it with the crankhandle

Re: Crank Pully Nut - b6319a
An update... 1 3/8" & then 1 1/4" too big, 1 3/16 is a bit sloppy but not enough that it slips, 1 1/8 to small. So I did get it to tighten up a bit with the 1 3/16, now my question is - where is this crank pully nut from ? Or is it just really, really well used ?

if putting it on you could take it off and have a good look at it. Try the sockets on and see why they won't go on. One of mine takes a 1-1/8 socket. It might be that the 1-1/8 is right but the crank dog ears are distorted and stopping the socket. You need a good depth on the socket too. If you take it off you can measure it with calipers or similar or try the sockets on from the other end to check if it is the ears that are causing the problem. Mart. |

Re: Crank Pully Nut - b6319a
Did 8RT or 8BA engines really come with a crank pulley nut?

Re: Crank Pully Nut - b6319a
Ok Just a follow up post to clear up some confusion for people who might search this post out for information in the future.
Thanks to VanPelts site for this info. 49-53 "8BA" should be a 7/8" bolt & washer: http://www.vanpeltsales.com/FH_web/F...twasherkit.jpg Earlier styles (prior to 1949) are the "crank" type which are either the "large" (1928-1947) 1 3/8" or "small" (1939-1948) 1 1/8" http://www.vanpeltsales.com/FH_web/F...ulleybolts.jpg So mine had the "small" 1 1/8" with bent cogs so only an 1 3/16 would fit, also it didn't have a washer so the small bolt would actually pass thru the bore of the pulley... basically the pulley was held on with the fan belts all these years while it slowly hammered the keyway out of the pulley... |

That's not good! But at least you found the issue.

Re: Crank Pully Nut - b6319a
I know 48-50 F-1s and bigger had crank holes.
1951-'52 F trucks could have crank holes. My '50 F1 with '51 front sheet metal had a place spotted for the crank hole but it was never drilled through or punched out. Under the center bullet is a spot for the crank hole. Untitled by Travis Brown, on Flickr |

Re: Crank Pully Nut - b6319a
I'm a bit slow on the uptake, I didn't realise this was on Ol Snoopy. Have you been able to locate a new pulley or whatever parts you need?

Re: Crank Pully Nut - b6319a
Dennis, get one of the smaller crank nuts. It is next to impossible to get at the large one with a socket on a 32 to tighten or remove once everything is in place.
With the smaller, 1-1/8" across the flats, you can slip on a socket and then with various extensions through the crank holes, get at the nut. Glenn |

Re: Crank Pully Nut - b6319a
Oh, some guys cut of the crank tangs too for better options. I like to stay stock as possible you have the small one myself.

Re: Crank Pully Nut - b6319a
Glad you were able to fix it. Now you have said what you did I think I may have saw it on the hamb.
I've followed your journey with that car from the day you found it. |
