Dabber16 Posted October 9, 2014 Report Share Posted October 9, 2014 My first TR6 project and only had the car a week. Looking for a bit of advice with regard to replacing the original static seat belts which have seen better days with inertia reel type. I have seen options of Securon type that look suitable on Rimmer Bros site. I am currently replacing the seats with MX5 MkII type and thought I may as well replace belts at the same time. Is the change to inertia belts a straight forward task using the current fixings? Does the seat belt need to be anchored to the floor or can it be attached to the side of the replacement seat, replacing the Mazda fixing? If anchored to floor, do I need the longer stalk type? Appreciate any advice. Quote Link to post Share on other sites
RobinTR6 Posted October 9, 2014 Report Share Posted October 9, 2014 Securon belts are the way to go , think its the 530 that you need. Search on this forum and you'll find the info you need. 3point type belt, top of wheel arch, just below B post and floor by the central tunnel. Length of stalk and type, is cable or belt you'll need to decide. Often available on eBay for somewhat less than the specialists. They are standard and fit other cars so not TR specials. Easy to fit.

Dave Smith Posted October 9, 2014 Report Share Posted October 9, 2014 Firstly if you have a UK car I think only the CR have the factory provided bottom fixing for the intertia. You can find them in the rear wheel arch, mine had a plastic bungs still there. The stalks if fitted to the floor are straight whereas the original were kinked to cater for the seat. If you MX seats I think the fixing is directly to that, if that is the case then that problem is solved. Also you may need one with a different serial number, to cater for that. Hopefully someone else with similar setup can help. I must admit I was slightly disappointed with the quality of my securon, (recently brought) but for the money there are good vaue. You can purchase these from many outlets - TRshop did have them on offer last spring. Quote Link to post Share on other sites
Red 6 Posted October 9, 2014 Report Share Posted October 9, 2014 It is not a good idea to fit the stalk end to the seat. The mounting on a standard TR seat are very weak just 1/2 (spanner size) bolts into captive nuts. In an accident they will rip out. Changing to an mx5 seat you will have a different subframe. The temptation is just to bolt them in in a similar way to that which the standard runner is fixed which will have the same outcome. The best idea would be to fit the new belt to the existing mounting points as those points are strengthened. When fitting a securon belt it is a 4 point fixing. 2 of the points use the existing mountings for the stalk and the anchor point in the cill at the bottom of the rear wheel arch. The retractor is fitted to the wheel arch behind the seat and is mounted in a vertical position. You need to drill a hole for the mounting bolt and reinforce it on both sides with the thickest washer you can find and some dum dum to stop water ingress. The last point is where the shoulder mounting goes. This is as high on top the wheel arch as is possible. If you are lucky the strengthened mounting point will already be there, if not drill the hole and again find the biggest thickest washer to strengthen the mounting point. The belt you need has a 30 cm stalk, I cannot remember the entire code but as Robin has said go to ebay and do a search they are usually about 1/2 the price of Moss and the like.

Dabber16 Posted October 9, 2014 Author Report Share Posted October 9, 2014 Many thanks gents for the advice, will check out eBay for the belts. Quote Link to post Share on other sites
stuart Posted October 9, 2014 Report Share Posted October 9, 2014 What you need is Securon model 500/30 They will work with the MX receivers but I wouldnt use them especially if you are using the flimsy mountings that most people use. The mounting brackets illustrated on the Technicalities CD however would be strong enough. Personally I find its just easier to use the original mounts on the floor pan next to the tunnel as they go into the chassis. Stuart. Quote Link to post Share on other sites
KOB Posted October 10, 2014 Report Share Posted October 10, 2014 Just a small point, if fitting the stork to MX 5 seat (this is what I have done) you should fix your seat runners to the floor with upgraded fixings as the 4 ( I think 5/16 bolts) are not up to the job in my view without underside plates and or increased bolt sizes and quality. Other than that its the way to go, I am 6ft 1" my lady 5ft 2" so the seat forward/back adjustment required is full travel and with floor mounted storks a real pain.

Jimgreen01 Posted October 28, 2014 Report Share Posted October 28, 2014 Hi all - I have a couple of questions for clarification (well, 3). I am thinking of fitting Securon 500/30 seat belts to my TR4. 1) Sounds like the receiver stalk can be mounted to the existing belt mounting point near the transmission tunnel (once the eye bolt is removed) - is that correct? 2) Similarly the end bracket can be fitted to the existing mounting point by the door? 3) Does mounting it this way foul the movement of the seats back and forth? I'm going to use Mk1 MX-5 seats. Thanks in advance. Jim Quote Link to post Share on other sites
mikeyb Posted October 28, 2014 Report Share Posted October 28, 2014 so why does the Securon website say 514/30 is correct for TR6? what's the difference between? Quote Link to post Share on other sites
RobinTR6 Posted October 28, 2014 Report Share Posted October 28, 2014 Difference is the 514 has the reel anchored to top of wheelarch to accommodate roll bar whereas the 500 is anchored with the reel at bottom of wheelarch and a guide at top of arch so 2 fixings on arch not one as the 514. No experience of that so can't advise. Quote Link to post Share on other sites
TR NIALL Posted October 28, 2014 Report Share Posted October 28, 2014 3 Point Belts I presume, Do 2 Fixings go to the Bottom of the B Post as in Doubled Up and Bolted through the Original Hole or duz one need to Redrill a Hole for the Inertia Unit onto the Base of the Wheelarch.

Jimgreen01 Posted October 28, 2014 Report Share Posted October 28, 2014 It's the latter I believe. The shoulder bracket at the top of the wheel arch, the reel at the bottom. Quote Link to post Share on other sites
TR NIALL Posted October 29, 2014 Report Share Posted October 29, 2014 On a 6 with MX5 Seats fitted and the Seat as far back as possible ie Touching the Wheel Arch there is No room for the Reel either at the Base of the Arch or on the B Post,think you would have to fit the Reel on the Inside of the Arch/Parcel Shelf and Plate the area accordingly.

Nigel Triumph Posted October 29, 2014 Report Share Posted October 29, 2014 Red 6 has given a thorough description of how to fit Securon inertia belts to a TR6. I fitted belts that way nearly 10 years ago, with one exception. The new anchor point for the reel must be reinforced but I used Securon's purpose made plates: http://www.ebay.co.uk/itm/SECURON-PLATES-NUTS-2-ACCESSORIES-STYLING-RESTRAINTS-SEAT-BELT-/300982061953?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item4613edcb81 These are made for the purpose and will be stronger than washers. The MoT tester has been perfectly happy with this set up on my car, though fortunately it's never been put to the ultimate test. Nigel Quote Link to post Share on other sites
TR NIALL Posted October 29, 2014 Report Share Posted October 29, 2014 Nigel,for Clarity can you please take a Picture of the Reel position and Post it here. Quote Link to post Share on other sites
Nigel Triumph Posted October 30, 2014 Report Share Posted October 30, 2014 Can do, but not for few days as I'm working away and nearly 200 miles from my 6. Will try to post a photo at the weekend. Nigel Quote Link to post Share on other sites

BlueTR3A-5EKT Posted October 30, 2014 Report Share Posted October 30, 2014 Here is a link to a picture of mine. https://drive.google.com/file/d/0B5E2f7j1weUAemE5ZU5pMkowcVE/view?usp=sharing Bruce Bruce's view is correct Post 1974 cars were installed with a seat belt reinforcer for the belt retractor box in addition to the the top arch and bottom B post fixings. That was to accept factory fit inertia reel belts ZKC3303. The more common fitment was statics ZKC1667. Both had a central stalk not a floppy belt. To see if your car has these reinforcers that are threaded to accept the belt anchorage bolts, take the rear wheel off and look at the underside of the wheel arch. They are pretty obvious to spot being metal plates with a large nut welded to them. Peter W Quote Link to post Share on other sites
