Bonnet Hinge bushing

[Hieter]

I was told in order to remove the old bonnet hinge bushing that you heat it up. Ok so once it's removed and you have the new one ready to back in do you do the reverse process?

Assuming you mean the top hat shaped metal sleeve. It should be an easy fit without requiring any force. If it's not you will need to clean out the hole on the bonnet frame until it fits easily.

If you heated it up you may have damaged the 2 nylon bushes that fit on either side of the bracket attached to the bonnet itself. You will need to replace these.

I replaced the metal sleeves and nylon bushes on mine recently - the metal sleeves were a very tight fit. By the time I realised how tight they were getting, they were pretty well stuck in there - I hope they never have to come out again!

I had one that would not budge. penetrating fluid made no difference. Neither did heat and quenching.

The hinge bolt came out but the top hat was seized.

I could not even rotate the top hat with stilsons. The bonnet was off at this stage.

I was worried that too much heat or force could damage the frame.

In the end I had to carefully drill the top hat out. Luckily the supporting round tube and the captive nut in the tube were undamaged.

So it was a success.

The next job I completed whist the engine was out was the dreaded mild steel heater pipes. That was worse.

By contrast, one of mine fell onto the floor when I took the bonnet off. Not just the sleeve, but the bush that's brazed into the frame also - the whole lot just fell out. I'm guessing it had seized up at some point and broken the brazing.
With regard to the water pipes behind the dash, I'm just about to do mine once I paint the under-bonnet area. I do remember reading on here (again, I can't remember the contributor I'm afraid) of a genius way of doing this; thread a rope through each pipe once you have laid it behind the firewall, then tie it in a loop behind your back as you stand in the engine bay. Then just lean back & pull the pipes into place while you rivet those round thingys on.

Well I could bore for England on the subject of e-type heater pipes Hugo,

I thought the string method was genius too. Until I tried it.

Like when I was 8, I thought that to survive an airplane crash, all you had to do was to jump out the door at the last moment before impact.

What you need is a 10 year old with skinny arms. Good luck!

Thanks for the encouragement. Isn't it often the case, though, that when you expect trouble you don't get it, and then a simple job can screw you up for hours sometimes?
Thanks for the tip about the ten year old. I have one of those. Lives a few doors up. I'll borrow him one day when his mother's not looking. His dad owes me a favour anyway.
