Belt slip and Hub Lubrication TS and 4HP

[Alan Cun]

Hello Readers       How often do you see the question how do I find or make a belt joiner for my belt driver my advice is you dont, might not be original but gets rid of one part that is just a nuisance and prone to break down. By all means have a belt with joiner for shows.     I think the first time I heard the following (C section 78) was from Don M at  a Canberra swap  about 1975 76,  and it has stuck in my mind ever since   A C 78 inch endless belt can be easily fitted by removing the rear stay and carrier bolt also the stand bolt and put the belt on .    But first remove the primary chain and loosen the box mounting bolts then retighten again      You will now need to fit a half link if not fitted to the primary chain (a Y shaped link with a pin and split pin in the wide end)    C 78 is for models with the 6 inch output pulley.    If its a 4HP a C80 fits mine .     My old TS would have done around  1000 k its been there 30 years it hasnt stretched it hasnt slipped .   The hubs        A wise old mechanic once said to me         Grease the bearing  oil the bush.      And thats what I put inside my hubs  good modern grease   Not woblybond gotcha grease that oozes out black . I reckon the hub packed with the good greases of today will still be good in another 100 years.   The above advice is my own opinion and comes with no copyright and I have no objection  or whatever to its future use. Same goes for any pics I have supplied to the forum   on other topics.   regards Al     PS  I welcome a response to this even if you want to just indicate how to produce a joiner link, also I would like to get a bit more discussion going on types of hubs and gearbox lubrication without opening a new subject.    Al

Alan, I think I am going to use a continuous belt on my TS. Have been trying a segmented T belt but will move that across to the veteran Peerless that is under way when it is ready for the road. Do you know where the length of the C belts is measured ? Is it outside or inside circumference ?

[Alan Cun]

Helo Ian    Not sure how they measure only assume it is a circumference reading   All the belts I have are clearly marked in white print One I noticed even has gear type teeth on the inner circumference   I buy mine from Dunlop general products  and they are still probably around $30  If you cant find  look up belts pullies engineering supplies etc in yellow pages.               I was lucky enough to attend an Agg Trend  Day today and managed to talk to a Moreys rep about additives  and greases.       I have often been asked the question if there is no gasket between the two gearbox halves how does the oil stay in.   My mate Des asked Castrol  was there a grease that gets thrown within the gearbox  and when the veh is stationary the grease settles back to the bottom.  Not sure what it was . I asked the Moreys  Rep and he replied double 0 He also informed me some new heavy vehicles have an external oil tank and the double 0 oil is pumped throughout the box. Another thing on TS is the hubs  3 types for TS Up to 1914 non Doug and you can tell them by one circumferencial ring each side of the hub oil cap.   From then on someone tell me we have across the hub  Douglas and DOUGLAS  which is for what models.  In my haste I have overlooked this in my restorations. I realise too there are heavier versions for 4HP.    Anyone noticed the good quality TS rims coming out of NZ around $120 I believe   Have a mate in Gympie that can roll the bead in the rims advertised in the drip feeds.  I know the vintage belt rims  but anyone any ideas on the two veteran style  some with smaller holes than the vintage and some with extra slot holes in the larger cicumference part.  regards Al

Ian,
When I went through this procedure to get a continuous belt for the 3 1/2 outfit, I took the Brammer belt that had been on the machine to the bearing shop and they put it on their special belt measuring device, and came up with a 70" belt. Miles too small. I then measured the diameters of the pulley and belt rim and the distance between the centres, and the shop came up with 84". Miles too big! Ended up fitting a 77" belt, exactly half way between the two measurements. This 84" measurement explained why there was an 84" belt hanging up in dad's garage - he had obviously gone through this procedure many years before!
Now you might remember in Canberra when we tried to fit up the brammer belt from the 3 1/2 to Jack's TS - it was too small. So my guess is that you need something like a 78" or 79" belt. I got Opti belts from SKF in Minto - they were pretty cheap - less than $40 from memory.
Alan, do you know by any chance whether the NZ connection makes belt rims suitable for a 3 1/2 or 4HP? They are a bit different to the 2 3/4. The rim on the 3 1/2 outfit split badly at the Centenary rally, and I need a replacement.
Cheers, Graeme

The local hardware in Picton has a great selection of belts - Maybe I will take the segmented belt down and just measure up against it - but they don't mind swapping if wrong - got one for my rideon recently and had to do that.

I guess another followon question - how tight do people run their belts ? Looking round at the rally there seemed to be everything from really tight through to 2-3 inches of slack !!

Hello All      This is taken from a customs declaration hope all the details are correct    ( rims un drilled good quality 26x2 half )          Garry Morton    company   Vintage Rims    address    74 Mt Lyford Drive   Waiau 8275     Nth Canterbury    New Zealand      Tele 03  315   6665      Info courtesy Rodney Pioch  Maryborough Qld     no further info on what other sizes or belt rims available       regards Al       Heh   got any of those TS hubs with spoke holes ripped off or the holes so badly rusted it only seems fit for the bin     Find another non Doug hub with 40 holes about TS hub size  Turn off each 20 hole section  and fit to TS hub just like  banding a worn sprocket .    Braze in place .    Yes we are that desperate up here they are getting rare.   Al
