  1. HI, only 4 sets left from 4th batch!!! 5th batch coming soon. Perfect sets, ratio and materials. Cheers, Harry Martens Limmen Gearbox specialist Citroen DS/SM and Lotus Esprit Giugiaro.
  2. HI here is one of those imitation pinion bearing. https://www.facebook.com/harry.martens.7/posts/pfbid02ENZXABTjwqGw1bCC3AuUTgxJysz7J8R3n7XDTSdSzLbcRmwjYqw1yDZmJ6ehHJNZl?notif_id=1653557486312733&notif_t=feedback_reaction_generic&ref=notif beware. cheers, Harry
  3. Hello, here is a link to more pictures. This time Esprit Turbo C 35 rebuild. https://www.facebook.com/media/set/?vanity=harry.martens.7&set=a.5474133822619221 enjoy!! cheers, Harry
  4. Here is some back ground information about the materials, design and quality HML ring and pinion sets. HML uses 18CrNiMo7-6 for those sets, which is the standard for hardened sets. The type of tooth is. Gleason, compared to Klingelnberg, has the disadvantage that Gleason has a smaller tooth foot radius and therefore succumbs faster to tooth fracture. In addition, the geometry over the tooth length at Gleason is a "circular arc". At Klingelnberg this is an "Epicycloid", which makes the Klingelnberg system less susceptible to installation errors and house deformation under load. If you are going to calculate with equivalent sets: Klingelnberg vs Gleason, Klingelnberg will be the strongest choice according to the calculation modules. About the transmission ratio. The cars with a 7-31 ratio will accelerate faster and you will lose your top speed. At the same speed, the car will also go higher in revs, which is less comfortable. cheers, Harry
  5. Full rebuild can be seen here: https://www.facebook.com/media/set?vanity=harry.martens.7&set=a.5322740114425260 cheers, Harry
  6. The first top quality HML reversed Lotus Esprit ring and pinion set from all ready the 4th batch has arrived!!! What really matters is performance, reliability and functionality. And most of all: Feedback from happy clients. Contact me for price and availability. All parts for Citroen gearbox in stock. cheers, Harry
  7. "quote " Harry Martens is pretty much the go-to guy for Citroen gearbox parts for Esprits and any other marque that uses Citroen gearboxes. He has developed a CWP specifically for Esprit use that matches the teeth with the way the Esprit uses the gearbox. I know of at least half a dozen people who have installed Harry's new parts and to date, they are all working well. Harry can also provide everything else for the gearboxes for one stop shopping, and will rebuild your gearbox if you ship it to him. New, all ready the 4th, batch of 12 reversed cwp sets for Lotus Esprit coming in the next few weeks. Well proven and without any weakness. Be wise. All parts in stock, full rebuild possible. cheers, Harry Martens the Netherlands www.ds-vitesse.com
  8. Hi, C4925 is paring number for casing and bell housing. Never seen the sticker before. Must be factory references I guess. cheers, Harry Martens www.ds-vitesse.com
  9. HI, you have not the correct gearbox for your S1. Turbo has C35 casing with only 1 drain plug. Bell housing is different. There are only 2 type. " previous "and " C35 ". I can supply you the correct " previous " gearbox with correct bell housing cheers, Harry Martens www.ds-vitesse.com
  10. Hi, imho failure while mounting on differential. Most likely not in line and with hammer. cheers, Harry
  11. Hi guys, these are not my "reversed " ring and pinion sets!!!!! Beware. Mine are fully tested, with nothing but good feedback. Mr John D is trying to sell un-tested and wrong ratio cwp sets without any feedback at all through my topic. I rest my case. cheers, Harry Martens www.ds-vitesse.com
  12. Some information about duty and brokerage fees into Canada. Auto parts for classic cars (at least 25 years old) should be duty-free for Canada, no matter the part’s country of origin. However, to make sure this happens, it is your responsibility to educate whomever you are buying from as most do not know about this exemption. Ask the shipper to indicate HS code 9966.00.00 on the customs declaration for each item as it applies. This Tariff Item of the Customs Tariff gives duty free status to “articles for use solely or principally with those vehicles manufactured more than 25 years prior to the date of importation”. Information about the interpretation of this tariff item can be found here. Eligible parts are limited to those solely or principally for qualifying vehicles and would have to be in keeping with the original appearance and configuration of the vehicle. These may be either original articles or reproductions. Articles that incorporate modern safety features or other technological developments can be considered under tariff item No. 9966.00.00, provided that they are solely or principally for use with qualifying vehicles and do not compromise the original configuration of the vehicle. EG Brake Kits, etc. General purpose articles that can be used in vehicles covered and not covered under tariff item No. 9966.00.00 are not eligible for consideration. So reproduction door panels would be eligible as they are specific to a vehicle over 25 years old, but tires that fit both your BMW 2002 and a 2011 Ford would not. Not sure if the rules are the same for US and Australia. Would be great for Lotus Esprit owners.
  13. For the HML " reversed " CWP sets, the offer is still valid!!!!! 350 euro discount for your old ( in mint condition ) original Citroen CWP. Quaife ATB diffs in stock again!!! Cheers, Harry Martens .
  14. Hi, my gearboxes comes complete. With output shaft housing and axles.
  15. Harry Martens Limmen 5m · Special offer!!!! Get discount for up to 350 euro for your old original Citroen CWP. Special offer!!! I will refund up to a maximum of 350 euros for your old original Citroen CWP when purchasing the HML correct " reversed " cwp set. See what can happen to yours. Many photos attached of failure, big failure!!!! Send a few photos of the teeth and splaines and you will receive an indication of the possible discount. Please no pitting and chipped teeth. Final discount is determined in workshop HML. Just in case you decide to send your gearbox to HML for rebuild, the same option is valid. Don't hesitate to ask any question about the Citroen " previous" and " C 35 " gearboxes used in Lotus Esprit from 1976 till USA 1988. Stay safe, stay healthy.
  16. This gearbox in fwd cars like Citroen DS, SM and C35, all have the same input shaft with support in flywheel by deep grove ball bearing. cheers, Harry Martens
  17. This is all ready the 3rd batch of 11 sets !!! Brand new correct “reversed “ ring and pinion sets Lotus Esprit Giugiaro. 23 sets sold!!! Unbrake-able so far! And byond. #lotusesprit #lotusespritturbo @ HML
  18. imho when spigot bearing fails the input shaft is no longer centert and will hobble in flywheel, followed by friction plate also hobbling around. Imagine with high rpm. Disaster. cheers, Harry
  19. HI Correct, the later Turbo version had the C35 ( commercial van ) gearbox casing, but with Citroen SM ( Lotus Esprit ) internals and off course Lotus bell housing. Not a direct swap and also difficult to find. The Citroen DS had some small differences for parts and ratios. Ch
  20. Hi, this not Citroen SM but Citroen DS 5 speed gearbox. Input shaft is 10 mm longer, short 1st and 5th gear. Do not forget to replace input shaft and if you find bell housing you have to measure carefully. Bell housing and gearbox casing have matching numbers. After die cast, both were machined as a pair. cheers, Harry
  21. Hi, indeed!! Many sold. All good feedback, ask here. cheers,
  22. so what should I say about that now? Compared to OEM and HML. "German spec alloy steel". That says nothing at all about the quality of the material. Not everything that comes from Germany is good. Once you have a certificate that describes the quality of the material, the same material from, for example, France is also perfect. And then you also have to indicate what material you use. HML uses 18CrNiMo7-6 for those sets, which is the standard for hardened sets. Measuring tooth thickness with a digital caliper ?? I don't think an engineer measures gears like that. A child can understand that if you mill fewer teeth in a certain diameter wheel, the thickness thereof increases. 21/5 gives an even thicker tooth. That does not mean anything about the strength of a tooth. The type of tooth is. Gleason, compared to Klingelnberg, has the disadvantage that Gleason has a smaller tooth foot radius and therefore succumbs faster to tooth fracture. In addition, the geometry over the tooth length at Gleason is a "circular arc". At Klingelnberg this is an "Epicycloid", which makes the Klingelnberg system less susceptible to installation errors and house deformation under load. If you are going to calculate with equivalent sets: Klingelnberg vs Gleason, Klingelnberg will be the strongest choice according to the calculation modules. About the transmission ratio. The cars with a 7-31 ratio will accelerate faster and you will lose your top speed. At the same speed, the car will also go higher in revs, which is less comfortable. All the best and good luck. cheers, Harry Martens
  23. Another Lotus Esprit Turbo gearbox failure. Pinion bearing exploded. Lot of damage. All due to wrong design for load on crown wheel. HML has found solution. Reversed set. No easy rebuild. Couldn’t find right pattern.See first 2 photos ( yellow marker ). Photo with white marker is from manufacturer. Perfect pattern. I found out the original gearbox casing, with exploded pinion bearing, has no visible damage but obvious there is no good alignment. New housing, all is good now. So beware with your original Citroen CWP. It runs on WRONG side!!!! Photos of installation new HML reversed cwp.
  24. Ok, I wouldn't know of that. Maybe some others here on forum have answers for that. cheers, Harry
