I understood as much about that lot as you will the above. God I wished I listened at school. Anyhow, does this mean I can have my alloy pulley now then?

AMMO Posted January 21, 2003 Share Posted January 21, 2003 Nope That's only four orders. Your mission Jue, should you wish to accept it, is to convert another six people to the light side (Mission Impossible meets Star Wars!). Gaffer tape is like the Force.

Miraz Posted January 21, 2003 Share Posted January 21, 2003 How big would these proposed pulleys be? Link to comment Share on other sites More sharing options...
AMMO Posted January 21, 2003 Share Posted January 21, 2003 How big do you want them? Seriously. I was thinking of reducing the diameter from 130 to 110 mm. Could be less. I will be guided by what the majority want. This has worked very well for me on the Zetec. I also looked very carefully at what the Yanks are selling. Checked the diameters and weights of Zetec pulleys for road cars. All seem to be running 110 / 112 mm diameter, 400 grm approx. The K-Series ones will be more than this as they have the extra 80 mm diameter pulley section to drive the dry sump. Maybe 500 grms. Not worth making two versions, with and without front section. As previously stated I want to keep some mass on the nose of the crank. Even running the alternator approx. 15% slower it will probably still be too fast. A bigger alternator pulley is probably still required. AMMO Link to comment Share on other sites More sharing options...
Julian Thompson Posted January 22, 2003 Author Share Posted January 22, 2003 Yikes. We're half full guys. (How many of you thought we still only were half empty?) Surely some more takers? Link to comment Share on other sites More sharing options...
prs Posted January 23, 2003 Share Posted January 23, 2003 Take a look on www.eliseparts.com they have an alloy pulley for the K series for somewhere in the region of £68 plus the taxman. Whether the configuration is exactly the same as a Caterham set up I don't Know though. Phil 😳 Link to comment Share on other sites More sharing options...
AMMO Posted January 23, 2003 Share Posted January 23, 2003 PRS Luke looked at these at the NEC show I think. They don't have the drive for the dry sump and are not hard anodised. AMMO Link to comment Share on other sites More sharing options...
Luke Beaumont Posted January 23, 2003 Share Posted January 23, 2003 It was the minuscule QED item that I saw at the show, though AIUI you're correct about the eliseparts one not being anodised. Also (from their text) doesn't seem to change the alternator gearing. I'm not going to use the dry sump drive on mine, but for the negligible extra weight I'd rather have a pulley with one.

Peter Carmichael Posted January 23, 2003 Share Posted January 23, 2003 Finally got to the bottom of the crankshaft issue. Standard k-series crankshafts are cast. Got this direct from the guys in Power Train who develop the engines. Link to comment Share on other sites More sharing options...
AMMO Posted January 28, 2003 Share Posted January 28, 2003 I will contact the pulley manufacturers today to see if they will make 5 prototypes and at what cost. The people on the list are: Julian, Luke, Ken, V7 SLR and Peter C. Are we all agreed on 110 mm outside diameter? AMMO Link to comment Share on other sites More sharing options...

V7 SLR Posted January 28, 2003 Share Posted January 28, 2003 Ammo, I am definitely interested but it is cost dependent. I have overspent on this year's budget already and have only a bit of spare cash left. Thanks for the effort. I'm happy with your suggestion of 110mm for the alt drive.

Peter Carmichael Posted January 28, 2003 Share Posted January 28, 2003 I reckon I can work with 110. I already have 80mm and 53 mm pulleys for the alternator so this gives me some room to manoeuvre. Link to comment Share on other sites More sharing options...
Chris Jones Posted January 28, 2003 Share Posted January 28, 2003 Ammo, Let me know how much your enquiry comes up with - I may well be interested. I thought the Zetec one I saw looked the business. I understand it is a "good thing" to uprate the oil pump rotor too - would hard anodised alu lend itself to this or would the steel QED item be better suited? Cheers Chris ps. TIme for another curry soon? Link to comment Share on other sites More sharing options...
Peter Carmichael Posted January 28, 2003 Share Posted January 28, 2003 Aluminium would not be suitable. Differential expansion compared to the mating gear and aluminium is very poor in its fatigue properties. You need a steel pump gear. Link to comment Share on other sites More sharing options...
V7 SLR Posted January 28, 2003 Share Posted January 28, 2003 How much and where from for a steel pump gear? Worcs L7 club joint AO.//Membership No. 4379//Azure Blue SLR No. 0077//Se7ens List Tours Link to comment Share on other sites More sharing options...
Peter Carmichael Posted January 28, 2003 Share Posted January 28, 2003 QED. ISTR ~80 quid. Link to comment Share on other sites More sharing options...
AMMO Posted January 28, 2003 Share Posted January 28, 2003 Chris, Peter, V7 SLR, I'm hoping to do them for the £80.00 + delivery + VAT previously mentioned. A kind of a loss leader to get a few out and evaluated. At least the CNC program will be written if any are required for the future. If five are totally uneconomical I may have ten made and put some on the shelf. I'll know what the situation is next week. Regarding curry, I want to rolling road test / map the fuel injection around beginning of March. Maybe we should organize Dyno / Curry 3?

Luke Beaumont Posted January 28, 2003 Share Posted January 28, 2003 Dyno curry 3: this time it's personal. Count me in for that, as either the 7 or the Pug will need hurling on the rollers around that time. Link to comment Share on other sites More sharing options...

V7 SLR Posted January 29, 2003 Share Posted January 29, 2003 If you take the oil pump off, check out DVA's web site (his own site rather than the DVA business) where he describes how to modify the pump's back-plate here.

Lawrence_Z Posted January 29, 2003 Share Posted January 29, 2003 How "hard" is it to change the oil pump gear? If you can change the cam belt, it's only one spanner more You'll need an oil pump gasket and perhaps the seal also. If you change to the Pace dry sump then you can toss the oil pump rotor in the bin........ Lawrence Link to comment Share on other sites More sharing options...
