Bonnet Alignment & Adjustment [hitting wipers]

#1 Post by Mr Teddy Bear » Wed Nov 02, 2016 12:17 pm

This seems to be a common problem and has been discussed at some length on other threads.

I hold a loose leaf copy of the Rover Workshop Manual AKM 6987 [2nd Ed'] 1994. While looking up something else, the page fell open at 'Bonnet Alignment' :angel

It would appear that the bonnet to body hinge has elongated slots machined into the hinge, allowing fore and aft adjustment by slackening the 4 bolt's sufficiently [ to allow grudging movement of the bonnet under soft persuasion/gentle tap with a soft faced mallet] NOT UNTIL the bonnet is likely to fall on your head :scared :cursing . Only make your adjustments after marking the present hinge position with a marker pen and with the bonnet lowered onto it's stops.


Aligning bonnet leading edges with front wings.
There is additional [vertical] adjustment of the bonnet catch. Achieved by slackening the 4 catch bolts, probably only necessary in conjunction with adjusting the two bonnet bump stops, at either side of the [ Platform, Bonnet, Locking ] panel.

The bonnet is a heavy item and will be a two man lift to state the obvious.

I haven't actually tried this myself yet, but will report back in due course. :wink3

I've got this issue on my 416 GSi, but I have to say the wiper arms do seem to protrude up a lot more on this, than they do on my other R8s where the arms are "flatter"

This doesn't work I can report back after trying it. I didn't take the bonnet off the hinges so perhaps the hinge slot is full of dried paint. I couldn't achieve any noticeable movement even after tapping the bonnet edge using a wooden block and a careful hammer. :sad

Bonnet alignment does make the bonnet move but it is really for the alignment with the wings and front area to get the gaps right. After changing the front wings - currently have a lopsided car with large indicator replacement wing and one original small indicator wing but had to adjust the bonnet to suit as the new wing has been on at least three cars! Was being moved from one of mine to other as I had a better one to go on the better car and the other one the original was seriously falling off!
Off subject
Wiper arms - the 240K mileage car does hit the bonnet and always has since about 150K. I have tried to bend the arm which works for a while. I have replaced the arm with similar but this does the same. My other low mileage (180K!) has no issues yet with the arm and I am convinced this is because it was an elderly gents car for 24 years and rarely went out in the rain - you would not know it from the shape of the bodywork but was outside parked. I prefer the argument about metal fatigue in the arms mentioned elsewhere on forum but personally I am sure it is related to the bearings in the first wiper box - at 240K the wiper box must have seen a bit of use and has a reasonable amount of wear. As the arm is quite a height away from the bulkhead and the arm has a spring pulling it away even a relatively small amount of play would be exaggerated and allow movement - I have only managed to get a complete wiper system off a scrap car and have not had chance to try to refit it on the high mileage car to prove my theory but it remains my favourite cause. Do not know whether this bearing can be replaced either by propriety item or homemade but......

It was probably me who advanced the casting 'creep' theory. Based on the observation that the side view of the arm casting no longer had any straight lines - there was a gentle curve superimposed on the lazy-Z. As I also noticed a bit of play in the spindle bearings, I re-bushed these, but didn't gain much bonnet clearance. I used these (2014 price):

Code: Select all

Qty	Model																						Products Total (ex)
4	  MB.1010.DLU MB1010D Permaglide Steel Backed Plain Bush 10x12x10mm		£8.92
It's possible to drift the old bushes out from the opposite end of the casting using a pin punch. However, due to the casting draft angle, the abutment for the bush at one end is too wide to get a good purchase on. I drifted the easy one out, then used my lathe to open out the casting. It was obvious from the feel of the cut when I'd reached the other bush. Then that could be drifted out.
