My Sad Sprockets

[SDeMocko]

Here are a couple of pics of my sad sprockets. I am posting because they are not like pics of others I have seen. Most of the ones I have seen looked as if they were made from plate with the only machining being a tapering of the thickness of the teeth. As a lurker I think I remember reading that the early ones had counter bores like these but my carrier is a MKII. Does anyone have a DXF of the correct profile?
Thanks,
Stephen

Hi, I believe those sprockets with a rim on them are for a british carrier, they do the same job as the others, check to see a 'TL' number not 'CTL'.#

I've not seen them before, A Canadian one is no different than a British one. The Australian carrier sprockets do have a shoulder on them, but nothing like these ones.

What does a Loyd sprocket look like?

[martyn]

there not british sprockets ? mine is a solid thickness and bolts up to a shoulder on the drum they dont have a cut out in the back ? mine were original sprockets taken off dated 1943 with a TL number not CTL
i carnt find the photo of my sprockets before we fitted them but have one of them on the vehicle and a shot of the hub before they were fitted.

[kevin powles]

Hi Martyn, You must of seen that rimmed type of sprocket!, Shauns got them on his carrier, I have seen them on three other UC Carriers, The rim go's on the outside. They only go on one way, while your sprockets like mine will go on either way round. I say british carrier as i was told they were british but saying that I have seen them on Canadian carriers. I will try and dig out some pics.......this carrier lark is all very confusing.

A bit like This

If you're looking for new sprokets, I could try to persuade ( ) a bloke to sell what look like 20 virgin carrier sprockets that form part of his front fence, along with variuos other Ag and Industrial wheels mixed in. He's not convinced yet.

[Lynn Eades]

I think they could be Loyd sprockets. I think the extra width is to help guide the track (help it stay on)
Loyds had a series of radiused angle brackets that bolted on with the sprocket locating bolts.
There was one for each pair of bolts.
Maybe these sprockets here were an interim idea to solve a problem, before the boffins came up with the cheaper option of the things I have just mentioned (which I assumed were a standard Loyd part) I believe these were also fitted to the universals, on occasions
A parts book could help, ..anyone?
You can barely see what I'm talking about on this Loyd

Could "Local Guy" and "The Bedford Boys" please add a name to their profile. It is nice to be able to use a name. Most of us on here have one

We must all remember that the drive train on Carriers goes back a long way and has a war at the end of it! The evolution of parts both reflects design improvements and production compromises. I suspect that the sprocket shown is an early version used until someone had the bright idea to simplify the manufacturing cost and time. The loyd version on mine and a 1941 dated example I´ve seen are flat, just like Martyns photos. All my sprockets are shot, worn to within an inch of their life by the Belgians post war. I too need a NOS example to get the profile from as I need to get four made. Will anyone in the midlands lend me one or a .dwg for the lazer cutting chap? I know Martyn hasn´t got one as his are bolted to the UC

The simplified sprocket doesn't positivly guide the track on a UC, but for some reason when Loyd used the standard sprocket they added the guide plates to run against the outside track horn as discused earlier in the thread, the other horn on the track runs an a deep groove cast into the drum. The sprocket is attached to the drum by bolts and special curved steel plates on the back side of the drum sprocket flange, thus on a Loyd the sprockets are bolted from the front and there are no nuts, the curved plates are tapped instead.

PS. Loyd brake drum is with the pattern maker now...worn sprocket is on the workshop floor, came off quite easly once Martyn had used his heavy duty socket set to split the drum from the hub! (thanks for the help)

Thort id seen them somwhere before couldnt rember if it was shauns or the old boy from gainsborough, yep carriers such a simple vehicle yet so confusing

Stephen.. can you email me your email address (yes i heard it guys),...... hahaha. i have something for you buddy.

Cheers

[Lynn Eades]

Those sprockets would not have been original to your carrier. It has probably worn out both track and sprockets,

[RichardT10829]

i must agreee with Lynn. i have been through the parts and service books and there is no mention of the regular sprockets being superseeded by these... most likely they have come from the loyd or perhaps a vickers light tank ? / T16.....not a universal carrier though.....of course i am known for being incorrect...

[Lynn Eades]

There would be a lot more work and expense to produce them. Vickers light tank is a good thought.

[SDeMocko]

Guys,
I meant to take the paint off of the part numbers this last weekend so I could post them. There are definitely some stamped numbers on them. I will take some pics tonight. Lynn, I think your right about my worn out track but my lack of experience keeps me from telling if too warn out. Anyway I will probably "Run What I Brung" at the expense of the next set of sprockets. Actually you can tell by counting track links cant you? I forgot about that.
Stephen

[RichardT10829]

The general rule as i understand it is if the tracks are down to 160 links...its time to change them out....sprockets would be changed at this point.... I know people who run with less links and they dont have any issues..... the tracks tend to lean over when they are caput... if you look at the rear of the carrier square on (with the tracks on and correctly tensioned) you may see that the tracks lean in towards the diff...or the opposite way depending on what has been done with the tracks..

if i may offer my two penneth....i would run the tracks and sprockets you have to start with until you can find more new track or sprockets etc. i would be inclined not to put new sprockets onto old worn track as you will dessimate the sprocket and finish the track off even faster.

just an option buddy.....

[shaun]

Those are the same sprockets i have on my MK2 * - i have the same on one of my spare axles as well. Yours sprockets are not that worn, they came out of the factory with fairly narrow teethon that pattern sprocket. also the general rule is that one pair of sprockets will last two sets of tracks (im sure thats in one of the manuels as well)

[SDeMocko]

Carrier Community,
I ground the paint off and the number reads Ford 44 CTL 3626-F. Thanks for the opinions Shaun and Richard.
Stephen

[RichardT10829]

well al be....... 3626F is the replacement sprocket.. it appears there were 4 prior types A - F how did i miss that the first time.... it is not listed on the exploded diagram i have but is listed in the FUC-03 page 8 right there in black and white !..


so to sum up it is a late production sprocket and was to be used once all the other (ABCDE) had been depleated it is a carrier sprocket designed for use on the universal Mk1* and Mk2* so I was right all along when i said "I am known for being incorrect"


Richie

[Lynn Eades]

We are ALL learners. Thanks guys

[ajmac]

Interesting, does that point to Vivian being right all along
The track did need better guidence than the flat sprocket gave! Once I get back to England I'll post a photo of a REALLY shot sprocket, these shown are in good usable condition as far as I can see.

[colin jones]

Good morning/afternoon/evening, I know its a bit late, but Just to say it is not from a vickers light tank.
Colin.

[Lynn Eades]

That sprocket is not the right one for the Vickers Light tank,(Mk6A) because its an Aussie sprocket, isn't it?
Those ones in that fence look about right.
My observations are that you tank should be running Aussie track (with heads on the pins (Vickers tank specific), not lead plugged)with wide wheels(same as Aussie wheels) that have flat spokes(same as British/ Canadian universal carriers)

[RichardT10829]

Colin...you got a vickers light tank !!!!!!! please can i marry you ? people may frown but who cares.....and i am a good cook and i dont moan about bits of armour lying around the house.....iam into open relationships but must stress that you date hot women.....


have i sold you yet hahhahaha

great stuff

AJ - i think your sprockets are more of a litterall rather than a metaphor of being shot ahahahahaha

[Ron Pier]

My Canadian Mk2 also has these sprokets with the rim..Ron

[kevin powles]

hey ron, were are your ice scrappers?.

[Aidan]

do you think they made this type of sprocket to protect the front nuts? Aidan

[colin jones]

Lynn, you could be right, they are of the same design as the aust one. I will do some research about them.
Rich!, I don't think I'm ready for another relationship just yet as there's too many good miles left in the one I've got. My wife is part of the ground crew for the f18 hornets here in adelaide so she's very handy when I need hydrolic work done or fix the odd turbine. And she's a great cook!!! And she loves lots of armour around as long as its not on the kitchen table.
Thanks for the offer and by the way I do need a 6cyl meadows engine for the vickers if you happened to see one lying around.
Regards
Colin.

Colin,
Does she have a sister?
