    One of the earlier  comments asked about stub axle stiffening

    Several companies offer a combined new stub axle and hub , usually but not always in aluminium.

    Starting from scratch the axle and hub are large enough to carry modern larger bearings

    Cost £600 with the up rated bearings

     

    The rather lovely units Classic Driving Developments supply are fitted with Timken bearings. Quality item

    Hi Richard, I’ve got and had the same crooklok for 40+ years in the TR… However, my neighbour who knows ‘everything’ informs me that the modern day thieves can ‘do’ them in seconds…… Just for information before you spend too much time and or money

    I think they could ‘do them’ in seconds in the old days! Hidden fuel cut off & a battery cut off are my primary anti-thief measures but I do also have 2 ‘Krooklock’ type devices available.

  3. A truly wonderful spectacle despite the sad occasion. So sad to see her horse brought out to say goodbye along with the corgis. Only we could have done her proud like that, a pity we cannot export it. A lovely lady deceased but I think the King will do alright. I shall never forget her & the past few days since her sudden sad demise. RIP your Majesty.

  4. We are back to this cheap rubbish parts topic again! If people stop buying this cheap stuff maybe it will disappear. These are good cars so spend the extra for a good quality name such as Timken from a bearing specialist. Too many inferior parts out there for our cars!

    Ive had a number of 4a through the workshops with run on issues and they have all been cured by careful tuning. Forget factory manual settings, each car needs to be tuned individually

    Stuart.

    Agreed Stuart, any rare run on problems with my car have been cured by a retune & higher octane fuel.

    It is indeed. I see that many of the later Triumph models (Spit/GT6/Saloon) seem to employ this method as per my pic, is it not efficient? Any reason it wouldn't work on a 4a?

    David

    I am sure it works but in my view I think it is better to recirculate through a catch tank as previously described rather than through the carbs or inlet. You should see the inside of the catch tank! Mainly residue from the crankcase breather probably but some must come from the rocker area.

    Unfortunately with that Triumph tune rocker cover theres no baffle behind it so even with that small filter in the line you would be ingesting some oil mist.

    Stuart.

    Think that is a flame trap Stuart rather than a filter. I have the same trap fitted to my Racetorations setup. I cannot really see that it can be efficient putting ‘stuff’ from under the rocker box back into the carbs or inlet, hence like you I have the Racetorations catch tank kit!

  8. I installed the Racetorations kit a few years ago & it has appeared to have worked well. I was lucky that the restorer/previous owner had already fitted an electric fuel pump so the mechanical pump location on the block was easily used for the Racetorations crankcase outlet. The amazing thing to see is the muck/gunge that is deposited in the Racetorations catch tank! A proportion of this muck & gunge would presumably have been sent through the inlet manifold via the PCV. I am sure the engine breathes & runs better & certain that it has got to be better putting that muck into a catch tank.

    That was a good result. The band that I was trying to remember was Manfred Mann. Thank you for the help. I was thinking they might have  light hair but the moment that I saw the picture I knew that this was the band I was trying to remember.. I used to watch TOTP every week. What do teenagers watch now ? How important is pop music in the modern world ??

    Thanks Richard & B

    They became the Manfred Mann Earthband. Saw them live a couple of times in London. Excellent!

  10. Thanks to all. Now sorted & understood. Took the carbs apart to check exactly what I had (drilled holes in the fillets so no need for holes in the caps) & cleaned the insides of the bodies & the pistons while I had them apart.

    Hi Roger, those deep ones will fit but you have to modify the inner wing (well, bash it with a big hammer and a large steel ball!!) where the front carb sits, think TR5 TR6 inner wing and you get the picture, ..... how do I know this?     well I had those self same K&Ns on my old Strombergs before Dad(bless him) bought me a pair of Webers, and the wing mod was just right for the long TRumpets and big Weber K&Ns.

    Cheers Rob 

    The pair I have are the thinner items with one having a corner ‘cut out’ to avoid the wing.

    Hi Folks,

     thanks  for all the info.

    I will look deeper into it through the day.

    K&N are expensive because they are K&N.

     

    Roger

    Roger, I cleaned mine a few weeks ago using the K & N spray cleaner & then re-oiled with their own oil. Now nice & clean with a nice red colour to the elements.

    As Ian says they are breather holes for early carbs to stop pressure build-up under the cap as the piston rises.  Later SUs have a breather channel in the body and don't need holes.  It is in the diagonal fillet at the top of the body going up to the cap which early carbs do not have.

    Thanks for that Rob, thought there was a reason somewhere previously. I appear to therefore have fillets in my carb bodies & plain brass (no holes) caps instead of black plastic. (Brass does look better than plastic).

  14. I have brass damper rod screw caps rather than the newer plastic variety on my SU HS carbs. At an event today I noticed a Mini had a similar setup with brass tops but each one had a small hole drilled in it. I remember reading something about these holes some while ago but have forgotten what they were for. Can somebody remind or enlighten me on their purpose & should I have them in my tops! 
    I have no running problems with no holes in the caps & I always ensure the chambers are topped up with oil. Just curious to know!
