Re: Advantages of a 3:9:1 diff

The original 948 in our Minor became a 994 (+060), and had around 50 bhp output (flowed 12G295 head, 2A948 cam, HS4 SU, LCB etc. and went very well with the standard 4.55 diff. It is now in a Frogeye Sprite, in the same state of tune, but with a 4.22 diff, and the first time the new owner tried it o...

Re: Positive v negative earth?

Some late Minors were fitted with a +ve, yes, POSITIVE earth 11AC Lucas Alternator (45A) - I have one somewhere in the garage that was fitted to various cars of mine in the 60's and early 70's. The wiring is a bit complicated in comparison to the simple plug-in of the later ACR alternators, as it us...

Re: 12G940 Cylinder Head

Phil,

The head has the recess for the thermostat - why could it not be fitted directly to the head in the picture?

Re: 12G940 Cylinder Head

Paul, The significance of the Calver article is the combination of no by-pass AND the blanking sleeve . With no thermostat fitted there is plenty of water circulation at all times. The whole purpose of the 'blanking sleeve' is to create a good flow around the engine, without a thermostat in place. N...

Re: 12G940 Cylinder Head

The A-Plus engines used a different by-pass system that had a sandwich plate underneath the thermostat housing. This also provides the permanent feed of hot water to the heater. Despite frequent suggestions to ignore the original by-pass hose and just block it off, no production A-Series engines wer...

There is a 'sticky' in the Electrical section of this board, which is a video outlining the conversion process. Does this give you what you need?

Re: Redundant wire from oil filter - green

The picture of the terminals looks like a classic Lucas alternator connector setup. If it is, then connecting a wire from the centre 35A Lucar terminal to the oil filter switch is pure madness! The terminal one of two on the alternator that are connected directly to the battery (no fuse), via the st...

Re: Redundant wire from oil filter - green

Definitely need to see where the green wire is connected to on the alternator. I cannot see how any connection from the alternator would be connected directly to either the standard oil pressure switch, or the filter by-pass switch. They are both 'green/yellow' and both switch a bulb to earth - swit...

Re: Suitable water temp sender for Morris Marina thermostat housing

As above, NPT and NPTF (F= Fuel) is the US pipe thread standard, and BSP(T) (tapered) is the UK and ISO standard. Although some sizes have the same TPI, they are not interchangeable. Both are used as parallel threads (NP and BSP) and taper threads (NPT and BSPT) There was a debate on this forum some...

Re: alloy or copper rad?

Phil, The flow through the heater is 'always on'. 2 reasons - 1 to get the heat away from the back of the head, and 2 to get the maximum flow through the heater element, thus hopefully 'warmth' out! The heater case has been fitted with a 'late' type classic Mini core that is claimed to be 'uprated' ...

Our hose arrangement is exactly the same as the link above. IMG_1694a.JPG When did the 'push/pull' heater temperature valve come in? ~1962? Is this the same point when the return from the heater was re-routed from the bottom of the radiator into the top of the bottom hose? When I fitted the 1380 eng...

Al, Reverting to your original question about reduced head thickness. If you have some new HT bolts and need the head reducing in thickness, I can do that very easily in the lathe - the plating will of course be removed from the head in the process! If you are anywhere near Oxford, I can offer a 'wh...

Re: Mr Grumpy Brake Disc Kit

Phil,

The reference I made to '5' and 'S' is in the Ebay link - the listing header description says they are 'S' and the body description says they are '5'! I would expect the original bolts will be 'S' or 'T'.

50 lbf. ft. torque for a 7/16" UNF bolt is quite normal.

Autosparks will recover/re-braid your harness using exactly the same colours as the original. Not cheap, but not silly either, and they will cover whatever you send them, so any additions, modifications can all be incorporated and look like they were there all along. Excellent service the 2 times I ...
