The Lotus Grand Tourers

Thats pretty cheap.

Thanks for the information.

I am guessing they are going to be selling a few of those in the very near future

Mine came yesterday by post, two day delivery. It looks well made and straightforward to use, so when the bank holiday rain stops I'll have the bonnet and the belt cover off and put it to use.

The gauge I received is an Optikrik 1 (the Optikrik range goes from 0 to 3). It has a dual scale of pounds force and Newtons and a range of 30pounds (130Newtons) to 150pounds (670Newtons). The resolution of the scale is 10 pound increments, so I found it difficult to measure with better precision than +/- 5 pounds. Stefan, does this sound like the same one? I re-tensioned my timing belt as it seemed a bit slack according to the gauge (although it sounded fine and seemed to twist to around 80 degrees).

Hi
Does not sound as the same one, mines called Krikit KR-1.
The upper scale is not used and the lower is in LBS and has got a mark on every 10'th from 30 to 160 LBS, so thats sound similar to yours, it took a while until i was comfortable with it, first time i took alot of measures, but it feels better the more i use it.
One thing i did to gain confidence was to measure a correct belt the first time so i knew better what i was doing.

Check out the link from my previous post.

All the best
Stefan

Hi Stefan, thanks for your description. Perhaps there is a US version (Lbs only) and a European version (LBs and Newtons). Anyway, I re-tensioned my belt to the range that you indicated (50-55 Lbs average over one engine revolution) and it seems fine. As you suggest, it's in my glove box. Cheers, Chris

I found this, Any help??

P.S. Could you give me more details about ordering, when I phoned local dealer, they did'nt know anything about them.





Special advantages
The simplified tensioning method is intended to facilitate the maintenance
of belts drives for the fitter, whenever the most important technical data is
not known and, therefore, an optimum tension cannot be calculated. With this
simplified method only pulley diameters are required.

1. Determine the section of the drive belt.
2. Measure the smaller pulley diameter of the drive system.
3. You can read the corresponding static tension from the table.
4. Control static tension with Optikrik according to manual.

Technical Data
optikrik 0 Measuring Range: 70 - 150 N
optikrik I Measuring Range: 150 - 600 N
optikrik II Measuring Range: 500 - 1400 N
optikrik III Measuring Range: 1300 - 3100 N

Hi Terry, yes, the technical sheet with the gauge has a look-up table of pulley sizes and nominal belt tension. I haven't cross-checked the pulley size against Stefan's data, but setting to Stefan's indicated value seems to be fine.
I called Brammer on the number given above and asked for their Peterborough office as it is geographically closest. Lucy was, I think, the lady at their Peterborough office who sorted out my order. She called me back to confirm which gauge I required (Optikrik 1) and that was it. As it is sent by post, I suggest you contact their Peterborough office and ask for Lucy. She should remember the order and be able to obtain another. Or I can order one for you if you tell me where to send it to and we'll settle up later. I'll take a photograph of mine tonight and post the picture. The gauge is no longer than a biro, so postage isn't a lot.

Here's a picture as promised. The gauge is placed on the belt and finger pressure is applied to the red button until it clicks. The belt deforms under the pressure, moving the heel of the red indicator through an arc that is proportional to deflection and thus indicates the belt tension on the scale.

Hello all! I posted this on the KRIKIT topic heading, but got no reply - so I'm trying again here.

Living in France, I ordered a KRIKIT 91107 (A.K.A. a 7401-0071) from my local factors, who got it in next day, but it did cost 32 Euros (that's £21 in old money...).

I have a question, please. All the discussions about this tool talk in terms of "Krikits" as the unit of measure - i.e. I should aim for "50 - 55 Krikits. However my Krikit does not have a scale marked in "Krikits". It has two scales, one in LBS, (with figures at 50, 100 and 150) and the other one is in KGS (with figures at 20, 30, 40, 50, 60 and 70. So my question is what does 1 Krikit correspond to? Would it be 1 LB ???

Would a photo of my Krikit help?

Alternatively, to how many LBS (or KGS) should I set my cam belt? (1989 EXCEL SE)

Many thanks,
Tony

Hi Tony, It sounds as though you have the same gauge as me - there is a photo via a link earlier in this thread. I set my belt tension to 50-55Lbs on the scale - seems fine several months and a few thousand miles further on . Regards, Chris
