Graze Posted September 20, 2015 Report Share Posted September 20, 2015 Ernie Try a good thump above the latch with a lightly closed fist Has helped me in the past Not so hard as to dent the bonnet Good luck Garze Quote Link to post Share on other sites
John Bracher Posted September 20, 2015 Report Share Posted September 20, 2015 Ernie, Bit like Graze's advice. Try 'CPR' (like they do it on TV) above the catch. No, not joking, if you can get the catch to 'bounce' it may pop open!! John Quote Link to post Share on other sites
jean Posted September 20, 2015 Report Share Posted September 20, 2015 If you have another person available ask him to stand in front of the car and push/pull the bonnet in an horizontal movement while you slightly push the bonnet down above the catch. This mostly works. Quote Link to post Share on other sites
ernie turner Posted September 20, 2015 Author Report Share Posted September 20, 2015 Hi all the trouble is when tried to shut the bonnet before this happened it did not just shut like it always dose. I notice the spring was slightly bent I turned the spring then it shut but looking now it has depressed lower than normal ,Thanks for all your advice . I have tried the ideas and so far no luck has anybody tried to get through the front or under where the starter is & up to the lock Regards Ernie Turner Quote Link to post Share on other sites
dingle Posted September 20, 2015 Report Share Posted September 20, 2015 (edited) This was for a LHD car, but might work for RHD, too. http://www.buckeyetriumphs.org/technical/Bonnet/Bonnet.htm Berry Edited September 20, 2015 by dingle Quote Link to post Share on other sites
Ade_TR6 Posted September 20, 2015 Report Share Posted September 20, 2015 The above does work on RHD cars but you have to remove the speedo or Rev counter (can't remember which) but I had to do the same many years ago when I had exactly the same issue. Ended up rummaging about with a long screwdriver but got the 'g' spot eventually and popped the bonnet. I put in an emergency release after ... Quote Link to post Share on other sites
peejay4A Posted September 21, 2015 Report Share Posted September 21, 2015 (edited) It sounds like what happened is the same as my problem a while back. The locking nut on the bonnet catch cone wasn't tight which allowed the cone to rotate out of alignment with the bulkhead catch. On the 4a you can remove the offside headlamp and slacken the bonnet hinge to allow a bit of wiggling. Can't be done on the 6 though aiui.

alan57 Posted September 21, 2015 Report Share Posted September 21, 2015 Search "bonnet opening" in TR6 section. Mine turned out to be inner cable seized in outer! Quote Link to post Share on other sites
John Bracher Posted September 21, 2015 Report Share Posted September 21, 2015 Following on from Peejay's comment, (from memory) is the bonnet catch cone 'slotted' like the head of a screw? Could you get a size FB screwdriver up from inside the footwell, and undo/wiggle it, like a long screw? I know it has a locknut, but maybe it would play ball? I would sooner drill a 1/2 diameter hole there than risk external bonnet damage! Quote Link to post Share on other sites
dingle Posted September 21, 2015 Report Share Posted September 21, 2015 I remember seeing a TR4 that had a large rubber plug in the bonnet above the latch. Probably a desperate attempt to open a stuck bonnet. Berry Quote Link to post Share on other sites
matttnz Posted September 21, 2015 Report Share Posted September 21, 2015 Most of the cures seem to relate to a broken cable but if you have the backup installed it sounds like your spring/latch mechanism is jammed. As far as I can see, various versions of "bash/wiggle it around a bit" is the fix. Followed by lots of grease when you do get it open +/- ensure all is lining up. If you are prodding about through the firewall or under the car use a broomstick, not metal in RHD... rather close to the Pos battery terminal...

jogger321 Posted September 21, 2015 Report Share Posted September 21, 2015 Out of interest which "off the counter" backup mechanism do folk recommend? Quote Link to post Share on other sites
John Bracher Posted September 22, 2015 Report Share Posted September 22, 2015 I have the kit from Moss. Modified it a little to avoid any chance of the cam/lever going 'over centre' (thus renedering it U/S!) Also changed from rod to cable operation, and made my own 'handle' for under the dash/footwell.

Rog Posted September 22, 2015 Report Share Posted September 22, 2015 Hi Ernie; I had a similar problem after closing the bonnet a little less carefully (actually allowed it to drop!!) in driving rain at Nurburgring after I had retrieved cloths drying on the engine. The flimsy keep was deflected down the side of the latch mounting and hooked up on the bottom. No amount of emergency cables would release this of course and the bonnet would only lift by a very small amount. Well and truly snookered and apart from drilling holes in the bulkhead I think I tried all the previous suggestions. Sorry to be a harbinger but in the end it was necessary to REMOVE the damned bonnet (viel geld!!) by removing hinge bolts. This turned out to be a pig of a job and my man looked as though he was into self-harming. Best of luck. Rog Quote Link to post Share on other sites
John Bracher Posted September 22, 2015 Report Share Posted September 22, 2015 Ernie, don't give up Son, you'll do it!!! Imagine the joy, when you 'pop that cork'!!!!!! Note to self. Clean and thoroughly lubricate ALL associated bonnet parts this weekend!! Quote Link to post Share on other sites
roy53 Posted September 22, 2015 Report Share Posted September 22, 2015 I purchased the after market safety kit after reading Alans woes a while back but have not fitted it as i don't want to drill the hole in the bulkhead to fit the operating rod.Any ideas on a different solution for this ?

stuart Posted September 23, 2015 Report Share Posted September 23, 2015 I have fitted an extra cable in the TR4 position i.e. r/hand side footwell pull and have a double mounted cable connector on the end lever. Takes less effort than the left hand pull and looks as if it should be there. Or the usual bracket and downward rod type (but with an end stop as noted above) Stuart.

John Bracher Posted September 23, 2015 Report Share Posted September 23, 2015 If you use a cable you may be able to fiddle it through an existing hole/gap somehow?? I drilled a 3/16 dia hole and inserted a nylon bushed rubber grommet (from work stuff) Works well, and nestles up under the drivers footwell with a 3" long aluminium extruded bar 'handle' Also a boon when you are working on the car, and can't be ars*d to run around to the passenger side!!

Lockley210 Posted September 23, 2015 Report Share Posted September 23, 2015 I have the rod type pull with an additional key operated lock. A locked bonnet is an added deterrant. Quote Link to post Share on other sites
ernie turner Posted September 23, 2015 Author Report Share Posted September 23, 2015 I would like to thank everybody for all their suggestions I will try them all the weekend Regards Ernie turner Quote Link to post Share on other sites

Johncracknell Posted September 27, 2015 Report Share Posted September 27, 2015 If it's still a problem, l would get / borrow an endoscope and position it from under the car, preferably on a ramp, so you can see the catch them fabricate something to get there from underneath to release the catch - probably a two man operation. A couple of hours messing around with this method could save a world of pain. Quote Link to post Share on other sites
jobster Posted September 27, 2015 Report Share Posted September 27, 2015 (edited) is it really necessary to open the bonnet? Otherwise, why all the trouble now if you can save it for later.......... (I'll get my coat..) Edited September 27, 2015 by jobster Quote Link to post Share on other sites
rhine Posted September 29, 2015 Report Share Posted September 29, 2015 Ernie, are you sorted? Have a look at http://www.buckeyetriumphs.org/technical/Bonnet/Bonnet.htmif you haven't already seen it. Richard Quote Link to post Share on other sites
