  1. Surely the drive shaft will try to push and pull within the yoke as a roll pin by its design is not a full circle and

    will compress as it is a sprung open "C" shape closes.

    I agree that if the yoke is shrunk on it is less likely to move but it is working against push/pull loads.

    The original Triumph shafts had solid pins I would have though they would have used 

    roll pins if they were suitable as they would be easier to fit.

    Hello Ben

                      Yes of course you can do you want higher resolution ones? if so pm me and I will send them to you

    Roger

    Thanks Roger, Those pics are really clear so will do the trick just missed my last deadline so will be a little while now.

    Thanks again

    Ben

  3. I think they need to understand that the drive shaft is also part of the suspension and the fact that it not only turns but it also pushes and pulls as the suspension works under load. The roll pin is getting compressed as its not solid.

    Roger I help the Marlin Owners Club with the Triumph based cars and would like to flag this up in a forth coming mag.

    Can I borrow your pictures which show the problem quite clearly.

    Ben Caswell.

    I have suggested this before with a members car using quite a bit of oil, and that

    was to not keep topping up the oil to the top mark, Like my car I find if you let it

    go till its about half way between the marks the consumption settles down considerably.

    Then just keep the top up to that level.

    I hate to think what these testers would do if presented with some of the pre-war cars.

    Thank goodness the experience tester know how to apply the requirements.

    May be thats why they allowed over 40's to be exempt!! saves on the tester training content.

    the original idea with the early cars was to fully retard the Vernier adjuster small wheel on vacuum unit) on the distributer set the timing to TDC when the pointer aligns with the mark and then adjust the Vernier 1 click  = 1degree but modern petrol is different so timing may need to be different from factory settings.

    I thought the markings were 4 deg apart on the vernier and it takes about 50 clicks between each mark

    that would make it about 11 0r 12 clicks per degree.

  8. Biggest risk is the accumulation of fuel vapors heavier than air including petrol and butanes mixing with unsafe electrical equipment.

    The following is taken from HSE Guidance note 261 (2009)

    . Preventing fire and asphyxiation
    228 Pits are likely to have poor natural ventilation so the release of any low
    flashpoint substance or heavier-than-air gas above or near a pit can create fire/
    explosion and asphyxiation risks. To reduce these risks:
    ■ ■ do not carry out pit work on non-diesel tanks or associated fuel lines where
    there is a risk of release. Do not carry out any hot work on or near any tank or
    fuel line, including diesel systems;
    do not store portable LPG heaters, or other LPG-fuelled devices, in or near pits ■ ■
    in case they leak;
    before carrying out pit work on air-conditioning units, empty the refrigerant with ■ ■
    a proprietary system well away from the pit area;
    do not weld in a pit unless effective local exhaust ventilation is provided;■ ■
    use fixed lighting in the pit that is suitable for potentially explosive atmospheres ■ ■
    and conforms to a suitable standard;
    use handlamps of special construction, that have been designed and tested to ■ ■
    prevent ignition in flammable atmospheres (see paragraphs 266-283 for further
    details);
    do not leave vehicles idling over pits unless there is dedicated exhaust extraction.

    Always think about your own safety and means of exit.

    Paul, keep an eye on the hole in the water pump. If the seals start to fail it can come out of the hole. The pulley can throw the coolant around. 

    Dave

    In the picture of the rad in the car it looks like the water pump is fitted one bolt further round as I think you can see the weep hole that should be at the bottom.

    Good to hear of good service:)

  10. I fear the external oil feed that increases the flow to the rocker gear may have robbed the cam of its share of the oil.

    Also depending on which sump you used with which dipstick would effect the working oil reserve in the sump

     as the oil level will change with the engine in the upright position.

  11. The paint on the block seems to have blistered just in front of the dizzy where the cam runs

    could this be a sign of things getting very hot in the cam bearing. I would also cut open the oil filter to see what you find in there.

    I hope you wasn't running an external rocker feed as that may have robbed the cam of oil pressure. 

    Sorry stating the obvious after reading all of your first post.
