Mounting gauges

Is there a "trick" to mounting gauges. I have a 1979 Jota and the gauges mount by steel straps tightening onto rubber mounting bands all held in place by 3 screws. Every time I have done it is a very frustrating experience trying to get the gauges straight and hold everything together then fit the screws. I am about to embark on the adventure again and will appreciate any suggestions to make the job as easy as possible.
Thanks in advance

Hi Ian there is a few ways you can do this if you remove the instrument bracket and secure the clock bands by the back 2 screws dont forget to put the rubbers in the strap first, leave the front bolt out now carefully insert the clocks with the rubber rings into the bands, push the front of the band back over the spiggot the front centre bolt screws into once again dont forget the little rubbers that go over the spiggot then you should be able to tighten the little front screw up easily after turning your clocks so they are at the correct angle.
This process can also be done with the instrument plate in position.
Good luck.
 
Mount steel support completely with rubber ring. Slide instrument in without the chrome back, a bit of silicone spray helps, then screw on the back once the instrument is in place.

Jota6297. Obviously you have the incorrect clocks. I suggest you look for others.


I will be happy to help you by taking those ill fitting ones off your hands.
 
It's a poorly designed mounting system, and often breaks at the centre bolt hole because there's not much metal left arounfd the hole. Even if it doesn't break, it will bend, leaving the clocks drooping like broken wings.

I recommend the modification below. Weld a bar across the front between the two bands. It'll tuck in behind the alloy mount bracket and not be visible once installed.

If the rubber grommets for the fixing bolts are replaced before they are totally knackered, the bracket lasts forever, unless it is unfortunate enough to hit a tree, of course.

But, if the perished rubbers are retained for decades, the bracket will droop and the guages get enough momentum from road shocks to eventually break the bracket.

Of course, most of us need to deal with the inadequacies of DPOs, replacing these grommets should be high on the to-do list of restoration or routine maintenance, especially now that they have become available again.

After having the bracket fracture at speed I got a local shop to braze a suitable size washer onto the underside of the front bolt mounting point-10 years later and it's still in one piece.  Stuart
 
The advice offered by Paul worked an absolute treat "Mount steel support completely with rubber ring. Slide instrument in without the chrome back, a bit of silicone spray helps, then screw on the back once the instrument is in place." Absolutely the easiest way to do this job. Thanks everyone.
 
Will never forget the first ride on my Jota when collecting it about 12 years ago....I had heard these things vibrate but this was unbelievable! Clocks shaking all over the shop, wtf!! Broken bracket syndrome as you can guess. The shagged bores, pulled studs, broken main bearings etc etc were a tad more serious and expensive to sort. :o
