This is just a short reminder to all you Citroën SM lovers out there.

It is extremely important to get in the habit of checking and correcting, if necessary, the tightness of the bolts fastening the differential shaft extension housing to the Citroen SM gear box .

This should be checked after any repair involving removal of the motor, the gear box, the drive shafts or the front suspension units.

The tightening torque is 10.5 to 13.5 m.kg. (76 to 98 ft. lbs.)

Stay safe!

So you want to flush out your Citroën hydraulic system?

OK, so one last hydraulic article and I will move on to other topics, but I couldn’t let you get away with out telling you about a hydraulic flushing product made by Total called Hydraurincage . We seem to call it Hydroflush over here, but Hydraurincage is the correct name for it from the mother land.

This is a good product that I personally have had some very good results with. Any LHM vehicle can benefit from the use of this product if it has any age on it or has sat around or been in storage for any length of time. Total’s Hydraurincage will flush and clean out the hydraulic system making it perform very near to new again.

Now here is what the manufacturer says for use instructions.

1. Drain the hydraulic system as much as possible (Also clean out the Hydraulic filter at this time)
2. Fill the system with TOTAL Hydraurincage . (Bleed the brakes until you see Hydraurincage coming out) (You want it throughout the system to get maximum results.)
3. Drive the vehicle for 1500 to 5000 Km maximum. (Take through one oil change or 3000 Miles)
4. Drain and clean the hydraulic filters . (You will be amazed at the amount of crud you will find)
5. Refill system with Total LHM Plus . (Bleed those brakes once again until you see LHM coming out)

The results that I have found with Total Hydraurincage in the system for just 100 miles is pretty profound. Much better steering response. If the car had Citromatic , or a hydraulic shifting transmission , the shifting was night and day better.

The ride was even improved. In fact, I am told that the product was developed during the production of the CX to help with the varnishing up of the suspension cylinders causing sticking in the suspension cylinder pistons and a harsh ride.

However it was developed is beside the point. It is just a very good product that should be used in every old LHM Citromatic transmission before you set it up with the Dellinger adjusting article .

Total Hydraurincage can be purchased in this country in the East from Brad Nauss Automotive at www.bradnaussauto.com phone: 717-691-8550. Tell Brad you want hydraulic system flush . (and tell him Denis Foley sent you. :0) )

In the West it can be found at www.westernhemisphers.com It is listed as part# M-1200435 Cleaner,hydraulic flush Total.

Now what this product does is get all the varnish and dirt out of the system and bring it back to the filter, and it holds the smaller stuff in suspension until you drain it out. Very good product that I can’t say enough about. Take care of those Citroen beauties, don’t make ‘em any more.

Later,

Here is a quick tip when setting the dwell on your Citroen Traction Avant 11B, the 11BL, or the 15/6. It also works on your Citroen D Model, both 3 main and 5 main bearing models. You can use it for the Citroen GS and pre 1982 GSA or the Citroen SM as well. It even works for the Citroen CX. For that matter, it works for any Citroen model that you may have that is equipped with a distributor with points.

This method can also be used on any car, truck, or motorcycle out there that has a distributor with points.

Assuming you have set the timing and the gap on the points it is now time to set the Dwell. Here are the steps to follow:

• Remove the distributor cap.

• Remove your spark plugs.

• Pull the coil wire from your Citroen’s coil.

• Make sure your Citroen’s transmission is in neutral.

Now connect up your dwell meter. If you have a Citroen D Model you can use the nice little starter relay that is located on the positive post of the battery.

If you are not setting the dwell on a Citroen D Model, then you want to use a remote starter trigger switch that is available at the same auto parts store that you obtained your dwell meter from.

Now we will assume you have a good starter and a fully charged battery.

Get your favorite small, flat blade screwdriver in hand. Flip on your ignition. So with your Citroen’s ignition on, your favorite small flat blade screwdriver on the points adjusting screw in the distributor and the dwell meter turned on, push the relay or starter trigger button and turn the engine over.

As you will notice with the spark plugs removed, the Citroen engine is able to turn over quite quickly with no compression. In fact it will turn over fast enough for you to see what the dwell is and adjust it very quickly.

So hopefully this little tip will let you adjust your Citroen dwell accurately and in a very short amount of time, without having to turn the engine on and off to take your distributor cap on and off.

Best of luck, and please leave your comments and questions.
