Propshaft to Diff bolts...

Post by **Multiphonikks** » Tue May 30, 2006 2:48 pm

Just tell me,

What *$%%&^(! Size are they?

I'm assuming whitworth - which would be nice since my whitworth collection is rather small...

Taken the exhaust and fule lines off and thought I'd tackle it as it's a nice day and the car is already on axle stands...

*Grumbles and goes to do something else on the car*

See - I'm working on her *now* so yell if you know the answer!

Frustrated of Bristol

They should be 1/4 whit.

Guess I'll be shopping later on in the week then! Thanks

It's the first Whit I've encountered thus far!!! ( And she's almost completely apart now!)

Of course they could have been replaced with similar size!!:-)

Ah yes, the unwritten commandment:

Thou shouldst replace, at every opportunity, bolts with heads different to the ones thy is replacing...

I do sympathise, somebody used metric bolts to hold the window winder in place which really foxed me! Good luck!

when rebuilding my car i replaced nearly all with metric bolts

easier availability over here

Originally they are 1/4" Whitworth, but some Minor specialists seem to be replacing them with 1/2" AF (I was caught out when working on a traveller from our branch). A 13mm spanner will hammer on to the bolt (to hold it steady) while you undo the other with a 1/4" Whit, but it's not ideal.

Well, I'm done for today... Just about to go and get a bit more clean han I currently am!

Jobs done:

Exhaust removed (That was a PIG)
Fuel Pipe gone
Wiper mechanism gone
Removal of most of the Dash now done

It's getting there.

I shall tackle the diff/prop another day!

A cunning combination of 13mm and 1/2 inch usually gets there in the end - plus free rounded bolts and bloody knuckles...

Eye, I got them and I didn't even try hard to remove the so and so

Post by **Cam** » Tue May 30, 2006 4:23 pm

1/2" usually won't touch them in my experience (if they are originals). 1/4" whit & 13mm will though at a push.

5/16" BSF. 1/4" is too small and Whitworth thread too coarse.
5/16" UNF will also fit nicely (1/2" A/F spanner)
M8 foreign equivalent (13mm spanner size) don't know how they would be in the hole though?

Post by **bigginger** » Tue May 30, 2006 4:36 pm

1/2 inch - did I not mention the big hammer?

Post by **rayofleamington** » Tue May 30, 2006 6:09 pm

1/4" is too small

?
1/4" Whitworth spanner fits perfectly if they are the originals.

However if they've been replaced they could be a mixture of anything.

Yes a 1/4" Whit spanner does fit a 5/16" bolt head perfectly but the original question asked for the propshaft to diff bolt size. Cam wrote "they are 1/4" Whitworth" which could lead to confusion - which it has.

True, but although the wording MIGHT have given a different impression, Nikki seemed to be asking which spanners fitted. She was not replacing the bolts, so I thought I'd simplify matters by suggesting the correct spanner for the job as in this case, the actual thread info is not needed.

Nikki seemed to be asking which spanners fitted. She was not replacing the bolts

couldn't see it any other way.

Yes, I just need to get the *#$&! off ;)

Still, I have plenty of time to regroup. I'm not going to be able to work on the car now until mid-June...

Oh well, differing opinions and interpretations on the English language.
Handbags at dawn then!! Or at the Potteries rally Cam? I've paid my fiver, hopefully I can find it this year.
Re the diff flange/propshaft bolts - the spare set (originals) I have would indicate they are non standard in both length and length of threaded portion, maybe made specially for purpose at the time?
