A bonnet adjust problem

Post by Moises Jr. »

Hello

We would like to know how we can adjust the front bonnet of the javelin ... do not know the reason, the radiator is a fair bit but does not seem to be the problem.

Any idea?

At the front centre there should be a post with two cones and a screw thread at the bottom with a locknut. This allows adjustment of the height of the two stage latch. You should have at least 2 cm of adjustment. In addition the two hinges at the back can be adjusted and washers can be placed ther to adjust the height of the rear of the bonnet.

If you need pictures let me know.

Are you overheating? If so we can start to investigate why!

Hi Keith

The front bonnet is not closed if the closure is low, I've tried and tried to adjust the rear hinges ... but welcome all kinds of info to solve this problem, the images will give us an answer. I will put other pictures to see if we specify the problem.

So far no overheating problems :)

Saludos!

Try removing the hinges & trial fit the bonnet with no hinges connected. This will let you know if the hinges are the problem,
the hinges are adjustable. This is a two man job & you will need covers to protect the wings & paint work.

Hi Moises,

Have you had the radiator reconditioned? We have found that when radiators are re-cored and rebuilt, the header tank can 'sit' too high and the radiator cap then fouls the inside of the bonnet? This then prevents the bonnet closing properly. Perhaps you could try putting a blob of grease on the top of the radiator cap, then try to close the bonnet, and look for 'tell-tale' signs of grease on the underside of the bonnet? This would show if the radiator cap is causing the problem.

Hope this helps?

Hello David

Indeed the radiator has been reconditioned, and the top cap makes a mark on the bonnet insulation ... but it is also true that without engine or radiator not close properly. The bonnet has reinforcement bars that seem to touch the radiator drain tube, or what they do when this down 1 or 2 centimeters.

Many thanks, saludos!

Hi everyone

New photos of the front bonnet theme, it is possible that the cable front bonnet opening from the inside, rubbing against the radiator.

Since the bonnet fitted well before the renovation , something must have changed . I just looked at my Javelin and tried to measure the difference in levels between the top flange of the inner wing adjacent to the radiator and the top of the radiator cap . It is difficult to be accurate but your radiator top tank seems to be higher than mine relative to the flange, judging by the last picture you posted .

As far as I can tell the difference in levels is about 11cm on my car , and I know there is very little clearance between the cap and the underside of the bonnet . Perhaps your reconditioned radiator is too large , or the attachment brackets near the base are in the wrong place . It might be possible to lower the radiator by modifying the brackets , I think there may be some spare clearance below the radiator ?

Another possibility is that the air cleaner attached to the bonnet is fouling somewhere, preventing closure .

All very frustrating , good luck Bob Lintott

Hi Robert

You'll discuss in a previous post, the front bonnet would not close completely when the engine was out of the javelin. It is clear that now does not close properly, and makes contact with the radiator cap, but before and did not work well.

attached some more photos

Saludos!

Do not know if it's an invention of mine, but I have the feeling that the inside bracket right front wing does not have the original height, it is possible a wrinkle? this would make the rest of the body bent forward in a low position.

What would be the best option to check the measurements?

Saludos!
