Re: Sidevalve head removal issues. Help!

No easy short-cut. Be careful since those USHM2 heads aren't easy to find. TDC, petrol, plug and a spark might get it to 'crack' the friction? Alternatively, filling the cylinder partially with grease and then winding the crank round fast to hydro-lock it? Neither sound appealing but might end up be...

Brake fluid theory

Just wondering about something this morning... I have an old, unopened Gallon jar of brake fluid that I was just about to throw away and it got me wondering. In THEORY water can leach in to just about anywhere to contaminate fluid, hence the short shelf life and even shorter service life. So, is the...

Re: Unblocking engine coolant drain tap passage

Citric acid becomes much more vigorous if the water is hot. Maybe run the engine with the filler cap off (no pressure) and then pour in the crystals just before switching off?
The down side is that it might attack the radiator tubes if they are already a bit thinned down.

Re: Spare bolt identification

Starter is 3/8 UNF x 1 3/4, I think. 7/16 UNF x 2.5 for the main caps.

Re: Rear brake light issue

Unbolt it and stuff the new one on. It should be a taper thread so you don't need to super-tighten it. Just a gooood nip. Tiny air gap can be helped by squirting some fluid up inside the switch before fitting. Not the end of the world if you don't. Did the same last week for the same reason and didn...

Re: Fitting a copper/nickle fuel line

Being soft copper you can bend it in situ with little effort. It is best to start, I think, at the back with the pipe fitted to the tank and unroll it from the roll as you work forwards. If you run it through the hole in the crossmember then you might find it hard to avoid damage as you drop the gea...

Re: Fitting a copper/nickle fuel line

You take the nut off the tank and the nipple is inside, soldered onto the end of the old pipe. You unsolder and resolder it on the bench. :D

Re: Can I get more power from Sidevalve?

The usual skim after some welding. I haven't taken it off of the block yet so it is still a complete engine. Previous owner said he had a head gasket leak after putting a new gasket on. Not sure what it will be like under there.

Re: Fitting a copper/nickle fuel line

Heat the old tank end and the solder will melt. Re-solder to the new pipe. bend it by hand, it is quite easy to do. For the pump end you can roll it round a bottle or tin can.

Re: Can I get more power from Sidevalve?

Got one here going spare, but needs some TLC. Other than that, a skim would help but then you get the age-old problem of balancing comp ratio with fluid dynamics. Derrington Silvertop head would be better than just skimming (Got one here going spare, but needs some TLC.) More ignition advance would ...

Both will fit. I doubt that an average 1275 will have enough guts to easily break an ATA version, but you never know. :D

Re: Diff Identification

The second one on the chart is also a 3.9 but with an ATA casing so it could be either version. I believe (but may be wrong) that the W1500/Riley 1.5 had ATA assemblies but the Midget had BTA ones.

Re: UFN 456 plumbing

That's a Morris 1000 dynamo pulley. Completely different size and shape to the groove, hence it doesn't fit properly. You need an MM or Morris 8 pulley. I've a feeling that car might have changed hands a few times since Hugh had it. When it was for sale there were lots of bits missing so one of the ...

Re: Diff Identification

BTA part numbers , such as BTA 806 for later halfshafts on Midgets, denotes a sturdier part. In the case of Diff it means a thicker web round the crownwheel carrier. Basically it means an ability to accept more Oooomph.

Next time I have to do this same job i'm gonna slice out the old captive nut and weld in a solid nut so the bu66er never fights me ever again. Any alignment issues will be resolved with a Dremel to the framework of the front panel. Job done!! :D

Re: UFN 456 plumbing

Top hose is OK or you can get 2 x 1098 temperature blanking plugs to close the ports off.. Bottom hose should go from bottom of rad to the bottom of the waterpump (assume it is fitted under all that stuff???) and a blanking plate fitted to the right side of the engine block.
