    Any tips on removal, rebuilding, installation will be sincerely appreciated...
    As always, I really appreciate the help...

    Hi Mike
    The actuator main piston isnt held in with any thing just the actuating rod. You may some fun getting the piston out as the only way pressure gets to the piston is via the shuttle valve.
    The schuttle valve moves as a result of the pressure from the master cylinder, once the valve moves system pressure pushes the piston.

    Another thought check all the lines to actuator to make sure they are cracked. My return line banjo was craked and it leaked/dripped.

    There is a remote chance that the schuttle vale is also warn (common) there isnt much you can do except have the total unit overhauled.

    Pleiades in the UK overhauled all my Hydraulics and its done on an exchange basis only problem I cannot find there web link.
    Here is link to a copy of there cataloge these people may be able to help.

    Hey Guys
    Have had a vibration which I thought was coming from back of car so been trying various things to find a solution. Had the new exhaust slightly altered; that made no difference; then decided to get the wheels rebalanced. As you know it's more difficult than other cars due to getting anyone with a machine that could do it. As I was dow for the Goodwood FofS I decided to pass by McGraths and get them to rebalance the rears. Seems to have made a difference but still think there is a vibration from the back at about 70+mph. Doesnt seem to go away although i have been trying very very hard to drive legally! ( in the UK dual carriagewas have a 70mph limit)

    If anyone any ideas let me know

    Paul

    OK Marc
    will come over to germany and give it a try!
    so far ever been above 135mph and keen to try the car at very high speed!
    It does feel a genuine 160 car!
    When is the book coming out? Was chatting at McGraths today as Andy has put all his books outside the office and some chairs as a waiting area for customers. No single Khamsin book. Hint hint!
    If you are publishing this year please put me down for a signed copy. One of my friends is publishing this year on a photographic book of famous people he has met ( a lot) and is using some form of on line limited publishing to minimise risk and cost. Happy to put you two in contact if you havent got a publishing deal sorted? I may use the same idea when I get around to my planned book on architecture in glasgow

    Well I aim to finish this summer, before the International Maserati club meet in Sweden in September. This is a far more complex book than the Breadvan one and even than the one I finished two years and 3 months ago but which my co author STILL has not finished. He is Scottish like you by the way! No I don't want to discuss the bas*%&d here.

    I have now driven every car covered in the book including QPII, Bora Group 4 and have far too much interview data and archive photos so it is a matter of painful choices.

    Tim Parker is publishing all three books and editions Drivers in France will do a French version of the Maserati book which I hasten to add is Maserati the Citroën years 1968-1975 so neither a Khamsin book nor another general history book however the Khamsin part will be by far the longest , most information filled ever published of course that's like saying the only girl in the room is the prettiest: sad but true there has never been a decent chapter on Khamsins in any book. I want to really give it its due. About time too.

    The actual printing of the book will not take place before end of 2010 most likely early 2011.

    Best of luck with your architecture book I think I saw somewhere photos of other cars under that archway you once used to shoot your Khamsin.

    best regards,

    Marc

    Superb photo and the Glasgow boys banner suits the cars too but not in the initially intended sense!

    Thank you for the offer but showing this forum to Tim Parker is enough to prove the enthusiams and I would not feel right getting a penny from readers before finishing the job!

    AM120076 owned by Ulf who contributes some of the most interesting posts here.

    Next to it is the Bora Gr4 of my friend Johan Helenius, who did a fantastic job on that car, as always.

    ...and AM120082 also in Sweden, a very attractive car despite, as Bob mentioned the Jaguar rear view mirrors.

    Right: dinner time good night!

    Marc,
    I don`t think that this car doesn`t match any of Gr4-specification! IMO its a pitty that a rare car like the Bora, that was made in only 571 examples, was modified like this.

    Same with the car that was "converted" in France!

    Ciao!

    Hi Paul...

    I was giving some thought to your vibration issue... I'm sure you considered this,
    but have you looked in the storage area in the left rear fender... Perhaps something
    small slid down in there and is rumbling around...

    Mike

    Hi
    the vibration was quite severe and could be felt through the entire car and was quite uncomfortable in such a generally refined car. It felt like wheel imbalance but didnt seem to go away completely after it kicked in about 74+mph and was worst at 78-82 although I couldnt say more as I didnt want to get speeding tickets!
    there was no real play in the bearing and no bearing grumble; the dampers seemed ok; the exhaust ha been repositioned; The exhuast is very tiht and no sure if it's a low frequency rumble, but used different gears at different engine revs and is speed not engine revs
    Could be prop shaft balance?
    Will rebalance front wheels too when I get home

    The Prop shaft is quite short and should be balanced.
    The gearbox has one mount the Diff has two hanging supports and two reaction mounts
    Have you checked the drive shaft CVs are tight?
    Especially the left hand inner, if some has changed the hardener belt an not tightended the CV this could be a good source of the problem.

    Regards

    Paul: thanks I hope to be able to post lots of Khamsin photos and data after Le Mans Classic this weekend, where I hope to see many k's!

    By the way who is coming?

    PM me for cell phone number exchanges.

    Walter I understand your feelings on Johan's Bora but they are not endangered like 250GTE's: we are talking about two cars over more than 500.

    I will report from the Artcurial auction on the Khamsin they offer Friday night but am mailny going there for the racing:)!

    best regards,

    Marc

    Hi
    I drove 380 miles home today and had vibration sometimes at speed and sometimes not! Will try that Graeme and see.
    Had a problem about 10 miles from home when water temp went up suddenly. fortunately a friend with a recovery business lived just off the motorway so went to her house and got car lifted back!
    Think it could be a stuck thermostat or possibly waterpump! Let car cool and then started again but temp went up very quickly. Belts for pump seem ok and think can see it spin so thinking is thermostat.
    Why does it always happen to me!
    Driven about 900 miles in past week and do enjoy the car. had some nice country roads to drive on and car was flying and making an amazing noise!

    Hi Paul
    I do feel for you if its not one thing its another been there hate it.

    Switch for the fans could be the place to start.

    Be carefull with over heating the fans dont cope that well. The Australian experience here in sydney with the stock radiator any thing about 28 to 30 C in traffic and they will overheat. Simplest cure is an ally radiator they actually run cool and need a higher temp thermostate ( mercedes)

    Worst case possibilities are,
    Thermostats generally fail open and the restrictor still works and the car takes ages to warm up.
    Did you notice any steam in exhaust? Head gasket?

    Is there a strange high pitch ding from the frount? If the drive cable has broken there should be a strange noise this is the fail safe pin for the pump some times people change the aircon pump and dont replace the fail safe drive.

    The pumps are fairly robust but early cars dont have the two face creamic seal and can leak and that should be visible.
    Loss of water , another culprit is the heater and leaks out underneath the car.

    I will be interested to know how you get on

    Graeme
