[quote][i]Originally posted by Kyle T[/i] I finally managed to get the house emptied of family members today after Christmas so got myself busy in the garage to unwind a bit... I'd ordered a new aux belt just before Christmas in the SeriouslyLotus sale, and was amazed when the poor Fedex guy banged on my door at 07:30 Christmas Eve! I decided to change the aux/supercharger belt as there's no record of it being done, and it's supposed to be a 2 year/20k service item. I guess there's a good chance it was changed back when the S/C was apparently changed in 2012... but that's still 6 years ago. I get the feeling some service items were skipped on this car due to the insanely low mileage. I'd never done the aux belt on my 111R, so this was an opportunity to try something new! I was hoping I could get this done with the rear wheel off and arch liner out, but no chance. The rollbar and some environmentally friendly looking canister device were blocking my view and access - so floor was coming off, again. Once under the car I got the pulleys and belt route mapped out the best I could. [img]https://i.imgur.com/uXoeWEU.jpg?1[/img] Next up was a challenge, this engine has an auto-tensioner with a very stiff shock absorber. The 19mm nut that I'm supposed to leverage was pretty badly positioned near the subframe so I could only get a shallow 3/4in socket onto it and a tiny little 6in breaker bar... No way I could shift it with that! I had a scoot around the garage and found some metal curtain poles left by the previous house owner... so out came the dremel and a few mins later I had a brushed brass effect cheater bar with a fluer de lis decoration on the end. Using my new tool I was able to slip off the old belt, I was keen to take it off properly rather than just cut it because I wanted to make sure I had the tools/strength to get the new one back on agan! This is the first aux belt I've ever removed, so I'm not quite sure what to look out for but it seemed fairly cracked on the grooved side with a handful of full-width cracks on the smooth side too. [img]https://i.imgur.com/gwpvZuS.jpg?1[/img] [img]https://i.imgur.com/g7qYurJ.jpg?1[/img] Comments welcome with regards to the state of this belt, was it a good time to change or is this fairly safe levels of wear? Final observation was that my new belt was a tiny bit longer than the old one. If I read these numbers correctly, out by 3mm: [img]https://i.imgur.com/84bwpbJ.jpg?2[/img] I'm sure that's well within tolerance of the tensioner but I double checked and everything I could find suggested the new belt was appropriate for my car. With the Lotus 2ZZ variations being quite... varied, there are a few belts floating around - but with AC and a Supercharger mine should be the longest one available, I guess. While the car was in the air I whipped the front undertray off too, it's one of the few panels I'd not looked behind. I found that the oil hose connecting the front oil coolers was no longer fastened to the underside of the crash structure with the sticky pad/cable tie combos and instead was bouncing around on the undertray. I'd noticed a bit of NVH coming from the front of this car, nothing too concerning as it's a rattly old Lotus anyway but it certainly wasn't present on my old Elise. Perhaps this is the source of it, but I won't be test driving today - too dark and too tired. The sound I'm hearing is quite hard to describe, it's not really a metal on metal rattle you'd get from a nut rolling around on an undertray or behind the dash or whatever - maybe closer to two pieces of material rubbing together occasionally. Big bumps don't really agitate it, but rough roads do. I initially thought it could be the fire extinguisher in the passenger footwell as that's the region it's coming from - but all seems secure down there, and is easily isolated when driving. Hoping to get out this weekend, some clear days forecast so might be able to make a day of it and get some nice pictures somewhere :) [/quote]
