time seemed to slip by and its soon time to pack up.

looking good

Thanks!!

I have been working full time for 41 years on military vehicles now, so I have picked up a bit of useless information on the way, and one day it helps myself or others.

Well I for one am extremely grateful to people like you and Clive, but that is relative to my toys.. So many specialist people it makes you dizzy:nut:

Richard,

I don't know what's more impressive, all your knowledge or the fact that you can remember and locate a drawing you made 20 years ago! Amazing, my hat off to you, sir!

That's why this forum is invaluable to all of us.....

That is unfortunate Wayne. Others have used that drawing without a problem, maybe they told the machinist what it was for and he gave it a bit of tolerance.

I suspect its the imperial to metric conversion that has caused the snug fit. I did explain reasons for use, but engineer was younger than me, so he followed by machine drawing.

Its easier to lose a bit than add it on, so it will be all good in the end.

The tolerance is probably less than 0.25mm as it slips over the end thread, but then is super tight ....

Cheers

Well I used the tool and its a bit tooooo snug.. Bugger!

I've checked the dimensions and its bang on,as per the info shared...

Its the merest of tolerance that is making it tight so was going to use a honing tool on the internal bore.

I'll be using the micrometer on the hub sleeve to see just how tight it is.....

I guess modern machining with computer accuracy means its very precise these days....

Update to follow with some pictures.....

I need to keep my spare camera with the tools, so I remember to snap progress.....

Hiya wayne great to see that you are making good progress on your project too, would be good to see you both at some shows next summer as I am aiming to get the Bedford sorted by the spring ready for the next season :-D

You know what its like with work and juggling the time with loved ones.

I have buggered about for ages with this, not getting stuck in and have been forcing the time on piggy.

Trouble is most of the time is spent restoring bits to be serviceable again... All progress but slower than bolting a new bit on...

Ironically though I enjoy that stuff as its therapeutic

Once I her stopping to match the going and charging then I can sort the prepping and preservation finishes.

I have decided to get her to shows before the rear side lockers are complete so that can be works in progress.

Also Henri is asking me when we are going camping in Humber at a show like Evesham!!!

It would be good to see you too

I know what you mean. They do look quite meaty and don't actually travel that far up and down the outer cabling.

My expander has arrived now which looks lovely in its old yellow Lockheed boxing. Picture needed I know

Infact after the brakes it should be mainly wheel arches cosmetic, painting and lighting to concentrate on.....

Probably a question for Clive more than the collective.

I am well advanced with the refurbishment of my brake expanders and tappet assemblies and need to get some photos added.

Also found a NOS expander, albeit with the incorrect handbrake cable (interchangeable luckily with mine).

I wondered if it was possible to obtain the handbrake cable assemblies, or get made up.

The existing ones are in good condition internally and after a little oiling slid freely in the outer cabling.

Just crossed my mind what happened if they went snap!

My front expanders weren't seized but the rear were, so I have redone all of them with meticulous cleaning and new seals etc, with the obligitory rubber grease usage. They all operate smoothly know :-D

Cheers

Looking lovely Jeremy.

Credit to your efforts indeed.

email sent

Received Clive. Many thanks as always :cool2:

Wayne in my evolved master list I have that KL2762 is the cup in the repair kit KL71490. It is likely that KL71475 is a kit rather than just a cup? Unfortunately my Lockhead/Automotive Products Co catalogues are packed away & I can't see what the kit comprises.

 

But are these NOS by the looks, would it not be better to buy new from John Walker & probably cheaper?

Could you pm me johns contact number again please?

Many thanks.

The seals state 2762. Does anyone know if the KL71475 are the same shape. Both are described as 1 1/8" cup seals.

I've emailed the seller but had no reply, and that was a few days ago.

Keen to get an answer to complete expander rebuilds.

Help appreciated

Thanks

Thanks Clive,I don't know what we would all do without you.

Struggle..................

PDF of the CAD drawing I did for the fabricator / machinist if it helps anyone out there.

Thanks to Clive and Richard for their help on this.

Regrettably I have had to work around a couple of timeframes and deadlines recently, but was delighted to see this on my desk this morning.

Richard thanks for the sketch

Matt

I have some Larkspur boxes, what you got missing if any. I'll check my stores.

Also seat guides arrived. So thank you very much buddy.

Wayno

I assumed you had drawing of original tool until I just saw the photo.

You can copy it by all means. (Normal charges apply: 1 x slab of beer)

Alas No!

I was wondering though how that tool slides over inner bearing, which is wider and must be fitted before hub??????

Especially as hub and drum are clamped together on refitting as per EMER.

Hi Wayne,

If the other end is identical, then the tool is not finished yet. See attached drawing that I did from an original army tool about 20 years ago. The four radial holes on right of side view are for putting rod or pin punch in to withdraw sleeve once hub is fully home. The taper is to ease the hub seal over without damaging it, the groove face of inner end of tool is to go over the inner seal to ensure no damage to it occurs.

Fook I wish I had seen that first Richard...

Can I print this off to speak to my chap.

Assumed it was just a sleeve with inner and outer diameters that were critical.....

Thanks for sharing though.

Best

Well Gents it has been made for my evaluation and I think it does nicely.

To top it all it has been machined by an engineer who spends his days amongst other things making Rolls Royce Gearboxes, so fitting that an RR connection should go with the Piggy.

Comments??

Do you really want to have to post them to Australia :undecided:

If they will pay postage. i'll box it up ........

I may be able to get some made cheaply out of solid bar by a 'Friendly' engineer / machinist / fabricator to the correct size and length. Still looking into it and firming final details on cost.

Seems reasonable at the minute, but have asked for a sample to be made first!

He will polish the outer face, which the seal slips over, so it will be as close to original as possible, even though I have not seen an image of an original :undecided:

I have enquired about having a few made and wondered who on the forum would be interested in acquiring one.

Clive - Any ideas of the MLUF would benefit from a post about this?

Thanks in advance

Wayne

Hi wayne the seals are standard 11/8 lockheed cup seals just bought some myself don't need to tell them what vehicle they are for regards roger

Roger I assume you mean the ones in the expanders.

Like these on eBay item number 151694690243

2 X NEW LOCKHEED WHEEL CYLINDER CUP SEALS KL71475 1.1/8" DIAMETER LISTED TO FIT MANY APPLICATIONS

Great info and thanks

I have a device that was more effective than the proper thing, I have found a spare one I've put on your pile.

Thank you Mr Christmas

Wayne the outer one is available as Gayco MI47552525.

 

The inner is no longer available. I bought the entire stock from Budge & have used up most of them with just a few left to see me out as it were.

Lets hope its not the inner one :shocked:

Thanks for the other reference. Appreciated :cheesy:

Dear Collective

I am currently working on the brakes on my Piggy and have noticed wet patch on inside of rim, the drum and once exposed backing plate, which suggests the slave cylinder / expander unit.

However as the system has been empty of fluid for a while I suspect it may be more like the hub oil seal that has leaked.

Are these still available and if not which pattern parts are best / a suitable replacement.

Thanks in advance

Regards
