  1. More Bonnet Hinges

    and to put it in context fixed spring was mk1-3 and they changed to swing spring on mk4 and 1500 to reduce rear wheel tuck under on hard cornering. Many myself included update both spring and ARB when restoring. The very late mk4 and 1500 also had longer half shafts. on 50+ year old cars what you have will often not be as it left the factory.

    early spit should be 11/16 later 7/8. However these have been changed over the years. the 7/8 was to counteract the greater roll from the later swing spring, which you may have. I run the later mk4 swing spring with 7/8 on my mk2 and of course someone may have fitted an aftermarket one at some point

     

  7. Speedo Recalibration Spitfire Mk2 1966

    in Electrical System

    Firstly does it need recalibrating to a different turns per mile or just reconditioning to original? The mark2 should have a 110mph speedo with 1248 turns per mile, this will be a number on the face to the top right of the needles spindle. If that is correct and the gearbox is a 3 rail and the diff still a 4.11 and standard diameter wheels then it will need resetting to original. maybe the magnets have weakend or needle moved.

    It should do 50mph at 3000 rpm in 4th gear. If it reads this but you are going faster maybe the diff has been changed so you will need to change the turns per mile or get a speed from the car the diff came from assuming it was a 3 railed gearbox car

    I used https://www.ebay.co.uk/str/classicspareseng1 when mine read high and is now pretty accurate. The 2 companies above will also do the job

  8. Bonnet Catches

    in Bodywork & Fittings

    personally I would get the tub etc swapped onto the new chassis before looking at that bonnet as it has had a lot of work done to it and you will never know how well it is likely to fit without a good chassis/tub to trial. I would also get it cleaned back to see what is actually there as there appears to be a lot of filler in the sidelamp areas and to assess the quality of work done.. 

    I definitely have the left hand light ring 612873 and the wings, they have been in my shed for 10 years, so there is no rush

    Lots of stuff is described as New Old stock but that could today mean 15 year old poor quality stuff unless you know the manufacturer!

    I have a number of bonnet panels in my shed. ie a pair of wings, one nos Stanpart with a few storage bruises and some surface rust and 1 pattern, I think 2 D plates and 1 light ring though I can't remember which side all bought to repair my MK2 bonnet but eventually converted a brand new MK3 as it worked out very little more expensive considering the labour cost. (not available now). I was just keeping them just in case but would part with them for a reasonable sum to help get another back on the road.Of course I used the sidelight repair panels to adapt the mk3 bonnet. 

     

  11. Oil pump question

    in Engine

    Posted

    The oil pumps are slightly different early are iron later aluminium. Also the pickups are different, the early 1147 didn't have a strainer then they went to a straight pipe with a strainer and the later 1500 had an angled pickup and I believe a slightly larger pump. They will all fit though as I have the late angled type in my 1147. I can't see why the herald and spitfire would have different oil pressure as it's the same block crank and oil pump (for cars of the same period) 

  13. Herald pistons - differences in 1200 engines, early and late?

    in Engine

    Posted

    just looked in the loft hepolite Nos 

    Split skirt  16178  fine for the early lower powered herald 1200 and prob even the 1250 but not ideal for the 67hp spitfire

    solid skirt with small end 18690  

    press fit solid skirt   18261 these are rare

    Most sellers simply put 18690 even if split skirt hence the no written in pencil which is why I bought a set which I have never used. 

  15. Herald pistons - differences in 1200 engines, early and late?

    in Engine

    As far as I know the difference was as Pete says split v solid skirt. The early pistons had an extra oil control ring below the gudgeon pin (split skirrt) these proved to be a bit weak on the more powerful (particularly the higher tuned spitfire engine) so they went to solid skirt. the later ones can be used in any 1147 engine but I wouldn't put the split skirt in my MK2 spitfire. The other difference (not sure it applies to heralds) is most 1147 engine had small end bearings with gudgeon pins held in place by circlips some spit engines had no small ends and gudgeon pins that were pressed in so no circlips. Either can be used so long as the pistons match the conrods. The other difference in the lower engine is the rear oil seal, early cars had the scroll type later had a rubber oil seal. Again interchangeable as long as the oil seal housing matches the crank.

  19. Vitesse windscreen washer

    in General

    I would first check that the non return valves are working there is one in the washer bottle and you may need one after the pump (I think there should be one in the pump but often fails). The inner is a rubber bladder which may well have perished my spit mk2 one did and then it leaks. They can be very carefully taken apart by lifting the crimp over the plastic end. If it is the same as the spit repros are available.
