Dumb question - Spare wheel support plates...And stuff

Post by Rev Light » Sun Dec 20, 2015 2:04 pm

Having removed my spare wheel from the engine bay for access for the weekends activities (drain and flush of coolant), it occurred to me that I might not actually put it back.

Looking at the boxing in of the radiator, etc. It looks to me that the plates on which the wheel sits might have a dual function, i.e. funnelling the air to the radiator. Has anyone removed them? Or is it not a good idea?

I have found that the very end cross member is pretty rusty and is holed in a couple of places, so it might be a better idea to bolt these plates back into place to add some strength to that front area until a repair is affected.

However, I find that many of the bolts that secure these plates are missing. What size are these bolts (UNC?) I am going to have to order half a dozen. And perhaps some heli-coils (however its spelt) to repair one or two of the captive threads.

Also my brass header tank is now leaking and the radiator cap need replacing. Where can I get a new plastic header tank and cap?

One step forward, two steps back.

Cheers

Not a good idea - put it back. The bolts are probably UNC as that's the common Scimitar size - might be worth using a tap before anything else - or just tap up to the nearest metric.

They should be 5/16" UNF - the ones into the top of the rad are very short though!

Hi Rev Light,
What did you use for flushing the system? I've just finished doing mine using the Halfords stuff, but the water hardly seemed dirty when I drained it, just a bit discoloured (I followed the rules on the bottle, too).

Coca Cola, followed by a solution of denture cleaner tablets, a couple of hours for each. Did not run the engine. After each time I flush through water, before filling up with 33% blue antifreeze.

However my main concern now is my broken brass radiator overflow bottle, as the system will now not pressurize.

Thanks for the bolt sizes, I get some ordered.

Cheers

I might have 8 balls old expansion tank somewhere but you can get them repaired?

It's probably worth getting a mixed pack of UNF and another of UNC - like these from Namrick. They give you a range of different lengths of bolts, setscrews, nuts, washers, in the most popular sizes (1/4, 5/16, and 3/8, from memory?), which gives you a handy starting point.

I'd agree with Phil about the two into the top of the rad being short - if you haven't got the originals, you may need to shorten new ones.

I will try and get it repaired I think, its only the little overflow nozzle, so should be able to run a bit of solder around it. Might strip all the old black paint off it and polish it up a bit. Bit of bling under the bonnet

I have a drawing of the front nose plate (I made my own a few months ago and had it welded by a local chap)

Will,
the plates are fine I think, the have been 'hamerited' back in the dim and distant past, so although scruffy the are complete. It's the front cross member that the foremost plate bolts to that needs looking at, although in the short term I will put some Rust remedy on it and paint it to stabilize its condition.. But it will need replacing down the line.

Cheers

Steve

hi steve
that is the nose plate it also supports the nose and the front bumper (or are you referring to something else )

Roger,

I have taken your advice and ordered two mixed sets of UNF and UNC nuts, bolts and washers from the above company, so that I have something to start with.

I have a rivet-nut tool, but it is in metric. I was wondering if anyone does one in 'old money', or is this a 'new fangled' tool, only available in metric? I have many missing screws, both inside and out, with odd bits of plastic stuffed into holes that are too bit for the screw they are meant to be for.

Cheers

Steve

If you're referring to holes in the body (used for the screws to retain, for example, light units) then they are too big as standard, and the "bits of plastic" may be the mangled remains of the lokuts (like these in this link ) which are the original fitting.

As for imperial rivnut tools, a search on google did turn up a few, though not particularly cheap as they are designed for industrial use - a few random examples here.

My pop-rivet tool does M4 rivnuts too, but I've lost the mandrel, and while searching for one on the web I came across a suggestion that you could actually do it yourself with just a bolt, a nut and a washer, but I have yet to give it a try!
