  1. The early hollow bullet fits something like the adapter in the picture; the later crimp I've shown falls straight though the hole! David
  2. I agree but I think the later crimps are a different size to the early hollow bullet. David
  3. If you mean the early style hollow bullet as opposed to the later crimp; these were intended to just have the strands folded back. Soldering may make you feel better but creats a weak point at the point where the solder wicking into thr cable ends, that's where it will break eventually. The key is moisture proofing. David Nice picture here:- https://www.autoelectricsupplies.co.uk/mobile/product/709/category/6
  4. I would agree with 1/8BSP. The two taps on picture are 1/8BSP & 1/8BSPT next to grease nipple and blanking plug. David Possible source with different thread selection:- https://www.namrick.co.uk/cgi-bin/sh000001.pl?WD=nipple grease&PN=Home_Grease_Nipples_50-1.html#a8031

    Cheaper to buy a complete set http://www.minispares.com/product/Classic/Engine/Cylinder_heads/Studs_bolts_nuts/C-AHT287.aspx?100409&ReturnUrl=/product/Classic/Engine/Cylinder_heads/Studs_bolts_nuts/CAM4545.aspx|Back to
  6. If the lock washer is too thin, is there any mileage in adding shims against the lockwasher? Aka Mini suspension ball joint shims. Don't know if the Mini ones would be the correct size unfortunatly ( they're 1+1/8 ID ; 1+1/2 OD and come in 3,5&10thou) but there will be something available out there that will fit. Just an idle thought.... David
  7. Think I've got something similar? Works well; has three differently cranked nozzles. David
  8. That comes up as 1/4BSPT on my search, so not suitable for the block. I quite like a tap on the block, so I've gone for a Vapormatic UK, VPE3603 drain tap. This is marketed for Massey Ferguson tractors (I can hear the sharp intakes of breath already). It's 1/2" UNF and needs a sealing washer - I've used a home made copper washer. The tap fits a treat and is pretty much in the same style as the later Triumph part. David
  9. Found this manual giving the setup procedure; might help you. Won't mixing tops and bottoms in your "bitser" horn will mean the mechanical throw is wrong and need reseting? Just a thought. David Lucas Workshop Horns 9H.pdf
  10. I'd give it a go - seems a shame to bin them. It's just a coil + diaphram and set of contacts inside. The contacts will probably need cleaning. There's a small adjustment screw towards the front of the horn ( not the large central screw); the setup procedure in the WSM calls for a 10Amp Ammeter to be conected in series while adjustment is made. David
  11. Does the Spitfire 4 differ from MK2 & MK3? Never thought about it before. On mine it's all the way out for maximum heat. David
  12. Looks like 1/2 x 20 UNF. Got a funny home made jobby. Trouble is 1/2 UNF, 1/4 BSP and 1/4 NPT are all pretty close to each other. David
  13. NPT and BSP are close, but not the same. Triumph used NPT threads quite often. https://pipeandhose.com/book/npt-vs-bsp-pipe Best comparison I could find with a quick search.
  14. Search for Quinton Hazell Y419, these are still available main line motor factors. David
  15. Some of those cheap pumps have a rough arm that looks like it's designed to saw through the camshaft! David
  16. Not sure if MGOC Spares are still open in the current situation - need to check; but remember 1500 fitted to Midget and their prices are good. https://www.mgocspares.co.uk/cgi-bin/sh000001.cgi?WD=ukc8523&PN=MGOC_SPARES_LINES___HOSES__MIDGET__184.html#a9387W_2dUKC8523 David
  17. Triumph filler and drain plug threads were originally 3/8 NPT Taper, but if you've got a different plug to use, you need the thread to suit that. Just remember what goes where! David
  18. I wonder if service manuals just specify engine oil for carbureters for an easy life. Austin / Morris are just the same with Mini in that early manuals specified 20w/50 but later manuals quote 10w/40 both for engine and carbureter. Basically I can't find a manual that says anything different than "engine oil" - whatever is being quoted for that. Personally I use SU Damper oil; works for me. David
  19. Hmm.. After some carefull measuring I think the early thread is 9/16 x 28-UNIFIED. I haven't got an example of the later boss thread so can't comment on what that is. The unified thread series covers UNC, UNF, UNEF and several constant pitch series: 4-UN, 6-UN, 8-UN, 12-UN, 16-UN, 20-UN, 28-UN and 32-UN. In amounst my boxes of bits I've found two 5/8 x 28-UN nuts; must be off a car I've had at some point in time; steering column boss maybe? So perhaps not so uncommon a thread. David
  20. OK, are we all talking about the same 105438 thread because the boss nut is pretty fine and certainly not 9/16-12 Whitworth. (Whitworth 1/2" tap next to boss nut). I think you're better of buying the nut. David
  21. Looks like 9/16-24 UNEF at a guess, but I haven't got a tap or die that size to verify it. David
  22. Johnathon, I think I'm with @NonMember as the best approach to take. Some idle mussings, as Pete would say:- On the single rail box fitted to 1500, isn't the gear lever only held in by the retaining ring ??? ; on the three rail box you would need to remove the small bolt and nylock nut that holds the gear lever to the rear remote control shaft aswell - not easy unless the opening in the tunnel allows access for 1/4" t- bar or you're a contourtionist and can access it by raising the tunnel enough! With the gear lever out, you could at least get the tunnel off and then replace the gear lever. Doesn't get it unstuck but at least you'd have better access. David
  23. Not sure why, but the aftermarket Delco caps seem to vary a lot between manufacturers. Generally the fit is too loose, but one I've got is actually too big to seat down properly in the distributor body . Managed to pick up a NOS Delco cap on eBay, brown in colour, fits perfectly; saving that one. David
  24. It seems many suppliers are selling BSP sump plugs, do they just see 3/8 pipe and assume BSP will fit! As Pete's data above NPT is correct; BSP has a different TPI and will not screw in very far or seal properly. David
  25. Purhaps you need one of these:- https://www.ebay.co.uk/itm/MAGNETIC-Triumph-MG-Sump-Diff-Gearbox-Drain-Filler-Plug-114774-15560-/222983483896 or one of these:- http://www.speedograph-richfield.com/html/magnetic_drain_plugs.html These have the correct taper thread. Seems to be a lot of confusing information on various suppliers web sites; some list a plug which is 3/8 x 19 BSP (straight c/w sealing washer) whilst others list 3/8 x 18 NPT (tappered). They can't both be right surely! I'll stick with the ordinary non magnetic taper plug David
