Hi Graeme, Can you help me on the procedure as on how to disassemble the oil pump from the crankshaft? I would appreciate your kind support. Armaz
Hi Armaz Unless the crank need a grind. and I dought it will leave the pump on the crank. The original crank on my car was so accurate when the machine shop looked at it they said. "do you want be to grind this, If you do I cannot match the accuracy of the original grind. If you do need to you need to pull the timing gear of the crank, they are schrunk on and you need a substantual puller to remove it. This Picture is from the the QportIII manual,although they are a wet sump the concept is identical. I would highly recommend that if you take it off get a new gear. They are pre heated to 160C and pressed on. And the new ones dont have the timming mark. Graeme Image Unavailable, Please Login
Hi Greame, I could not agree more! To me this is a very scary construction by Maserati. The parts book shows a metal bar that slides in a slot in the crankshaft and the gear but in reality it is not there! The triple gear is purely a shrunken on!! Imagine this gear has splines in the front where the shaft goes in that drives: the hydraulic pump, the aircon compressor, the water pump, the alternator and the gear itself also the camshafts! Only brave men engineer something like this. I only went through this once: I cooled the crank by a CO2 fire-extinguisher, heated the gear quickly with a flame and pressed it off! To press the triple gear back on I went the same procedure backwards. Of course, after measuring the outside and inside diameters at room temperature and checking that the parts were not damaged. So, Armaz, do not touch this if not absolutely necessary! Regards, Bart
Hi, Thank you Graeme and Bart for your comments and advise. The problem I have is I need to rework (grinde) the crankshaft and I am not sure if I could keep this gear on and still get the accuracy requiresed. What do you think? Best regards, Armaz
Hi Armaz Sadly the safest way to grind the crank is to remove the pump which means removing the gear. The Other reason is balancing the cranks and I would be very hard to grind the crank with the pump on and not have the pump being contaminated. Regards Graeme
My Khamsin still suffers from some "incontinence": The water pump still drips occasionally and after coming to grips with the majority of the "vino verde" I found out that my gearbox leaks. Originally I thought it was vino verde that I found under my gearbox after driving bu now I found out that it comes from the gearbox and I have no clue where from! The outgoing shaft is dry and all the nuts and studs at the rear side of the box are wet. Before collecting the energy and get that gearbox out I wonder if anybody has the same experience? Further to my previous messages on the expansion reservoir I received a comment by a Khamsin driving friend that he fills the reservoir mounted on the top of the engine up to the little shield mounted inside. To me this would mean that the top hose is only half filled. Anybody any comments on this? The owners manual does not give any details on this. Looking forward to any information on these subjects, Ciao, Bart Image Unavailable, Please Login
i made the crank gear and puller when mine was ruined by a clod. extra is for sale. gear is made from 4640 steel, puller works perfect. gear 600, puller 400
Hi Bart Gearbox is straight - Exhaust off - Hydraulic clutch off- disconnect drive shaft. Lower box remove Speedo drive. The bell housing bolts are easy to get to. You will need remove center console and the gear lever. Hint with the gear lever the base is bayonet fit see parts book picture. I added a cool header tank extra tank which I have posted before as away of combating overheating, now cured with an aluminium radiator.

Hi Greame, Thank you for your feedback. yes I was afraid that I had to dive in deeper. Won't get it ready for the upcoming International in Seefeld Austria, September 22 till 25. will do that in the winter time. We will take the Ghibli to Austria, no punishment either! Ciao, Bart
Dear Graeme and Bart, Thanks to your hints we made a tool with which we manage to remove the gear from the crankshaft. This tool looks a bit different from the one you introduced to me. I was concerned about pulling the gear with only the aid of the foreseen thread, so we decided not to pull using the thread but to pull from the rear side of the gear next to the pump. For those who might face the same problem I have attached the tool we used. Best regards, Armaz

Hi, I was wondering if anybody would know what is the material specification of the crankshaft? I know it is a stainless steel but which type? Furthermore, does anybody have experience with the nitriding process of the crankshaft? As far as I know there are three type of processes used for hardening a crankshaft: 1. Nitriding, 2. induction hardening and 3. tuftriding. The process originally used on these type of crankshaft was nitriding, now I am wondering if we could use induction hardening to achieve the same goals. What is the desired hardness and depth on the journals? I look forward to your comments. Regards, Armaz
Just got this photo from Doug's AM120341 (right hand drive 5 speed) which was repainted in April in its original luci del bosco. A lot of work has taken place, full and proper restoration reaching the final stretch, and it will definitely be at Khamsin Quaranta! best regards, Marc Image Unavailable, Please Login
And in the back we see the 5000GT #103.026! The 5000GT-motor is the most impressive GT-engine of all from Modena! Ciao! Walter
Hi Armaz The Cranks are nitrided to a depth that allows the crank to be ground to the first oversize. after that it requires re hardeming. Another process that is new is cyrogenic hardening. http://en.wikipedia.org/wiki/Cryogenic_hardening Regards Graeme
Good morning all: Another one found, about which I had nothing, 028. It is an hour beyond Bologna in Italy where it was sold new, third owner, got most of its use in 70's and 80's, now gets driven for an hour or so every 3 months, slightly insufficient but it is apparently fine. What is interesting is that not only is it one of relatively few smooth nose cars left but its original color was oro Longchamps, light gold/champagne which is now my favorite and very rare color for a K. The family wants to sell but has not decided on a price. If anyone is interested I am in touch with them, very nice people. It would be wonderful to see it back in its gorgeous original shade. -In other news we are putting the final touches to the KHAMSIN QUARANTA presentation and entry forms and owners please don't worry you have not received them but neither has anybody else yet! Thank you for all the messages of interest: there are at least 110 K in private hands in Europe and the UK so we are aiming to get a good portion of them! This figure does not include the dealers as this is an event by enthusiasts for enthusiasts so no dealers and for sale signs. As a reminder the dates are June 14-17, 2012 near Dijon Beaune, France, right at the center of where most of the cars are in Europe: Germany, the UK, Switzerland and the Benelux countries. It will be a very special, unique and worthy occasion, the aim of which is to gather as many as possible to celebrate it and get it the attention it always deserved but too rarely got so all owners are invited to join us! If you think I don't have your contact information please contact us offline, this applies in particular to those owners who read the forum but do not post. We can be reached at: [email protected] best regards, Marc Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login

Hi Marc Interesting to note the Khamsin Script Bertone Badge on the glove box, was this an early feature? Out of curiousity how many Cars have you been able to account for? Regards Graeme
Hi Graeme: No that is not original, just an owner who wanted to remind himself what he was driving Found, thanks to you and others here such as Walter, Joe Corbaccio, our Scandinavian friends and Andy Heywood about 330 of the 430 but of course on many I have just a few sentences of data or odd photo. Right now it is 3747 photos and 373 folders but each folder is NOT a car. Now I am really digging into the forgotten and hidden ones. Our friend Bart here just found another in Holland though I am not sure if it is ok to mention that one here...Bart? If so I would love some photos, for my files and or the forum. I won't be going to the meeting in Austria but a friend of mine is and that should yield info on several as there are about ten there. Then I want to dig in Venezuela: 4 cars IIRC, anybody have connections there? I have a young lady who will help me with Japan (31 cars) but they have bigger problems right now... Also tomorrow I am going to western France 800 miles in a day(!) and will see not only 016 which is being restored from scratch but should also see another one, 162, tucked away in a castle, though I saw it at 500 Ferraris agaisnt cancer and posted photos here in June of 2010. That car while red now may well be the second white French car I have been looking for. What is very interesting is that its owner told me last night that Citroën sold some cars, bypassing Thepenier and that he has the lists: whoa!!! In actual fact as I stated here once before my first ever K sighting was in Paris in 1974, fresh off the plane from Lisbon where we then lived, in front of Citroën's headquarters Quai André Citroën, there was a silver Khamsin triple parked for a big director no doubt and I, 10 years old, was watching this drooling from the back seat of the Citroën DS we were in! best regards, Marc
162: no I was wrong, I just saw in my Thepenier notes that it was originally silver, not white so perhaps that list of Maseratis sold directly by Citroën in France will reveal the other white car (the main one being 050 which has been in many articles in France). MS
Hi Marc and other enthusiasts, I was chasing some Ghibli parts for a club friend (who had a disaster happening to his car) when I was talking cars with a car friend when he mentioned a collection of Maserati's in our small flat country including a K! I had never heard off it, not that I know all but being passionate about Maserati for some 45 years (I started very young...) and a founding member of the Dutch Maserati Club means that I have more than the average required brain damage This K coming out brings the count in the Netherlands to 11 vehicles! I was utterly surprised to learn that this car, AM 120 US 1152 in "resale" red with automatic box, has been in our country since 1994, the engine is just done and is now undergoing conversion to manual and bumpers to Euro spec. Yes, another set on the pile, in wintertime we may practice down hill skiing from it! The owner is a very enthusiastic man an we will meet after the Austria Int'l event. Just learned that there are 100 cars and equipes staying in the hotel and 120 cars participating on Saturday!!! Promises to become a nice time together, lets hope for some good weather! Ciao, Bart
