I only manual shift ....up just under 3000rpm and down close to 2000 maybe 1900rpms...simply to get the best fuel consumption rates....and stay under 90 kph on secondary roads.....I can easily get the fuel consumption rate down to 3.6 maybe 3.5 LPHK What will this mod do when shifting in manual mode and shifting carefully? I see it soley for wear and tear on the belt..? I have never seen a worn out altenator pulley like the one shown.....perhaps they were all steel pulleys? Why are they alluminium, simply for weight savings or speed to turn the small pulley? I'm also on the fence about it making much difference if you are making the altenator work in any way. Just spin one by hand and then draw a load from it, it'll drag very quickly and depending upon the load it'll be very hard to turn by hand I bet! So it's a catch 22 imho, yes it may work if you are not using the altenator as it'll spin freely but if you are demanding power from said altenator then it should help slow the motor down some....imho.....and after saying all this I could also be completely wrong, but this is how my old brain see's it. sorry. Now, what if you decreased the dia of said pulley? Then what? Just a thought? Decreasing the diameter of the pulley would increase the alternator rpm for a given belt speed. To answer my own question, the restrictor plug is to get the thermostat to function more efficiently and get the engine to proper operating temp. I did a 0-100 km/h test last night and it's noticably slower than the video at roughly 21 seconds but I don't think I'm getting quite as good a launch as shown.

tolsen Posted February 2, 2019 Author Share Posted February 2, 2019 I just measured diameter over top of the grooves or ridges on an original Smart 451 Cdi pulley: 53.7 mm diameter hence 0.4 mm less than diameter of INA 535005910 pulley. Smart 451 Cdi pulley is rather expensive £104 from my local dealer in Aberdeen. I was smarter and bought pulley complete with alternator for £55 delivered. Came off a wrecked low mileage 2012 Smart 451 Cdi. Quote Link to comment Share on other sites More sharing options...

Willys Posted February 3, 2019 Share Posted February 3, 2019 (edited) Just started doing some digging.....is this correct...???? Check cross referance to Chrysler and Jeep...? https://www.amazon.com/VOLVO-Alternator-Freewheel-Clutch-F00M147907/dp/B00C8107SY Then went searching for item, found it cheap.....$32 or close...?

DF comes from glow plug controller but rather thin gauge cable, far too thin in my opinion to carry enough current to energise alternator field. The other cable connected to alternator’s wee push fit connector is larger gauge and i have concluded it carries battery sense voltage. One fine day I will connect an oscilloscope to DF and see what signal it carries. 1 Quote Link to comment Share on other sites More sharing options...

Willys Posted March 13, 2019 Share Posted March 13, 2019 Tolsen.....what was the last verdict on this free wheeling clutch pulley....lol. I am having a hard time locating it over here in the colony.....lol. I am venturing over again, this summer for a month perhaps....so could sneak one back in my hand luggage if it is cheaper there...? Or should I say easier to locate. Thanks for the knowledge as usual..... Quote Link to comment Share on other sites More sharing options...
Willys Posted March 13, 2019 Share Posted March 13, 2019 I'm going after this one.... SKF VKM 03302 or GATES OAP7080 https://www.onlinecarparts.co.uk/gates-7743638.html My cousin in England is purchasing it....time will tell. Quote Link to comment Share on other sites More sharing options...
tolsen Posted March 13, 2019 Author Share Posted March 13, 2019 INA 535005910 costs typically less than £22 here with free UK except Highlands and Islands delivery. Quote Link to comment Share on other sites More sharing options...
Nigel Posted March 13, 2019 Share Posted March 13, 2019 (edited) Willys I’m interested as well if we can change it without too much effort. I’ll square up with you next time I see you. No rush my car won’t be home before the end of June anyway. Nigel Edited March 13, 2019 by Nigel Quote Link to comment Share on other sites More sharing options...
stickman007 Posted August 15, 2019 Share Posted August 15, 2019 So finally did this mod! My pulley chewed up a new belt in less than 4months! It was squealing every morning. I cheap out and used aliexpress: https://www.aliexpress.com/item/32792437985.html?spm=a2g0s.9042311.0.0.4f214c4dPWj2lZ I definitely do not recommend this brand as my alternator tool doesn't actual fit in there...the socket was slightly too big (you could use a hammer and tap it in, but then you won't be able to get it out). I was not able to tighten the pulley as much as I like, but it should be fine as it will get tighter due to the rotation and the direction of the threads...I hope. But the pulley does work quite well. Noticeably smoother shifts. Thank you Tolsen! Quote Link to comment Share on other sites More sharing options...
rustyvolvo Posted August 31, 2019 Share Posted August 31, 2019 (edited) Just working on doing the INA pulley with a rebuilt alternator. Took off the pulleys on both the original and the rebuilt and I don't see a spacer, how thick is it?

Won’t fit Roadster and any petrol Smart. Reason: Different make of alternator and not same thread size as the diesel Smart 450 and 451.

Chopper Posted October 1, 2019 Share Posted October 1, 2019 Different number of grooves on the petrol as well. I looked at it myself, then lost interest and never went further. Quote Link to comment Share on other sites More sharing options...

Chopper Posted October 2, 2019 Share Posted October 2, 2019 If I'd thought about it I'd have done that while I was doing the alternator belt! There are 5 or 6 different variants for the petrol Smart 450, they all look identical, but only the correct one will work, and I don't know which for sure mine has as I wasn't savvy enough to look while I was in there! That being the case I'm loathe to buy another to measure up. I will do it, probably next year. I'm going to use the winter hiatus to stock up on parts I want to fit, so when the spanners come out next year I'll have another loom at it then.
