Thanks for the fast reply.👍

Is that 7.5ml per carb per 20 accelerator pushes, per carb barrel x 20 or for both carbs all barrels x 20? Cheers Mike

Hi Everyone. I've done a quick search and cannot find any reference to oil filter alternatives to the Lotus OEM Filter. As Lotus must get these made for them and branded for them I was hoping someone had experience of other brands of filters that are as good if not better than OEM filter. Info on the current thinking on oil grade and brand would be useful too for a 1982 N/A 2.2. Cheers Mike

Hi I am looking for the Gates Part number for the small belt that runs only the water pump from the crank on a S3 N/A. I have a new Gates 6218MC belt which is the wrong belt as it is a combined belt to drive the alternator and the water pump. Can anyone supply the info please. Thank You.

OK so having checked out the situation regarding the Air Con I am not going to put the belt on as the system is empty and I am going to leave the job of sorting the Air Con for when I move house and have a garage with a ramp. The next question is does anyone know the gates product code for the small belt water pump only belt? I have a gates 6218MC which unfortunately is a belt for a combined water pump alternator drive. I have a three belt crank pulley due to having air con fitted the alternator and water pump have separate belts. Cheers Mike

Thanks for the answers guys. It all sounds simple enough but ideally I could do with a photo of the tensioner set up as I am working from above with the engine in situ and a chassis brace running right in front of the pump making things awkward. I can only work by feel from above as I don't have access to a ramp at the moment. Cheers Mike

I have a few questions about the Air Con. The car has been unused since 2004 I am recommissioning. Can the Air con system use modern gases? Does anyone have photos / description of how to adjust the air con idler tensioner in situ. Does anyone have experience of fitting a slightly larger belt as original spec seems too tight to allow adjustment? Cheers Mike

Thanks for the info. As I have 2 of the earlier style "T" belts I think I will use these first then replace the early sprockets with the later HTD sprockets.

Both belts have 133 teeth and all sprockets are in good condition no dirt and a rebuilt tensioner. The 2.2 uses the same belt as the 2.0. I quickly tried the standard 5146 and still didn't manage to get it to time up. I will have a proper go next week. One thing I did note is I can feel the 5146 belt has elasticity while the T104RB is very very rigid with no perceivable give. I think I have just lost the knack of fitting the cambelts in situ😄 its been a few years since I have done one.

Does anyone have the Gates part number for the HTD HC belt? Now Ive found my set of HTD pulleys I am thinking of fitting them instead. Cheers Mike

I can stop the speculation regarding the T104RB profile. The official specification states "Trapezoidal". I have placed it against the original Gates 5146 Trapezoidal belt and it matches exactly as stated earlier on this thread it is the colouring which seems to fool the eye. The blue in each tooth is semi circular but the outer part around the blue on each tooth is square. I have tried it against my set of later HTD cam sprockets and it is no way round in comparison to the profile on the HTD pulleys. The profile can be seen on the photo next to the HTD Cam Sprocket.

OK I have found the answer the belt T104RB is classed as a Trapezoidal Belt not round tooth.

So the T104RB is the correct belt for the Trapezoidal pulleys it appears?

Hi Steve are you running the later spec HTD cam pulleys? Further note I have tried timing the engine with the belt on both ways I know in the photos the belt is on the wrong way around but the results in trying to time the engine remained the same, I now have a Standard Gates 5146 to try out.
