markjonesx 1 Posted March 17, 2012 Report Share Posted March 17, 2012 OK, there is a Hex screw on the timing pulley, does it undo anti-clockwise? Mines a right bugger and won't shift......

andydclements 790 Posted March 17, 2012 Report Share Posted March 17, 2012 Standard RH thread. Got an old belt? You could use the help secure it in a vice and prevent it turning (belt round pulley, belt into vice jaws and clamp, then the pulley cannot rotate). Quote Link to post Share on other sites
markjonesx 1 Posted March 17, 2012 Author Report Share Posted March 17, 2012 Got it clamped, heated it up, put WD40 on it over night, still stuck, maybe it's time for the big spanner.....

910Esprit 546 Posted March 17, 2012 Report Share Posted March 17, 2012 Probably a case where a dedicated good quality hex allen drive socket will make all the difference. (unless that's what you are already using....) Quote Link to post Share on other sites
77 esprit 0 Posted March 19, 2012 Report Share Posted March 19, 2012 Mark, During last years tear down after my timing belt fiasco, found I had the same problem. Actually needed to get to the last bolt on the water pump. Tried everything to get the allen head to release. Wound up taking the entire oil pump / distributor drive assembly off the engine! Just to get at the last bolt! Just don't understand why Lotus went to an Allen Head drive screw when there is plenty of room for a hex head bolt. Guess that is why Lotus had such a wonderful reputation for building "kit cars"! Tried the dedicated hex drive socket as suggested by Steve. Had the same result as you.

markjonesx 1 Posted March 19, 2012 Author Report Share Posted March 19, 2012 I have sorted this now using Andys trick with the old timing belt around the pulley in the vice. Heated it up and also let some WD40 soak in overnight. Good socket and my breaker bar did the job. Quote Esprit S1, 238G, Blog Online Photo's This car was most definately hand built, NOTHING FITS!

Sir Paolo 5 Posted March 19, 2012 Report Share Posted March 19, 2012 Standard RH thread. Got an old belt?

Sorry for being so dense, but I assume we're talking about engine out of the car? Quote Link to post Share on other sites
markjonesx 1 Posted March 19, 2012 Author Report Share Posted March 19, 2012 Yes, the engine is on total strip down. Quote Esprit S1, 238G, Blog Online Photo's This car was most definately hand built, NOTHING FITS! Link to post Share on other sites
77 esprit 0 Posted March 19, 2012 Report Share Posted March 19, 2012 Mark, Was warned by my Lotus Guru heating the pulley might ruin the bearing in the drive. He mentioned the screw / bolt was installed with Loctite. As the pulley rotates in the same direction as tightening the bolt, why oh why would they use Loctite? As my engine is still not running, can't tell you if I correctly re-installed the oil pump assembly! Can tell you the Allen Head is still securely installed retaining the timing pulley! The new / rebuilt water pump came with an Allen Head bolt to replace the unreachable hex head. Starting on attempting to install the new timing belt tomorrow. Weather should be in the high seventies. Wish me luck! Lyn Quote Link to post Share on other sites
Sir Paolo 5 Posted March 19, 2012 Report Share Posted March 19, 2012 Yes, the engine is on total strip down. It would have to be really. Otherwise, I couldn't see how the vice trick would work. I suppose you could use the same trick when re-fitting/torquing the pulley back again? Quote Link to post Share on other sites
markjonesx 1 Posted March 19, 2012 Author Report Share Posted March 19, 2012 One more question, how does the woodruff key come out? Does it need some help with a centre punch?

andydclements 790 Posted March 19, 2012 Report Share Posted March 19, 2012 More of a flat drift or a very small hammer. Flat drift on the visible end pushing it toward the oil pump, if the visible end is pointing down so you cannot do that then use a small hammer and very light strokes to tap the other end down, the visible end will then raise up and hopefully far enough to either drift as above or just push out.

markjonesx 1 Posted March 19, 2012 Author Report Share Posted March 19, 2012 Done it. Quote Esprit S1, 238G, Blog Online Photo's This car was most definately hand built, NOTHING FITS! Link to post Share on other sites
markjonesx 1 Posted March 19, 2012 Author Report Share Posted March 19, 2012 How does the dizzy casting separate from the other small casting, do they just push apart after you have separated the lock plate? Or do I need to hammer on the oil pump end of the dizzy shaft? Quote Esprit S1, 238G, Blog Online Photo's This car was most definately hand built, NOTHING FITS! Link to post Share on other sites
910Esprit 546 Posted March 19, 2012 Report Share Posted March 19, 2012 Dizzy will just pull out after you have loosened the clamp. Is that what you mean? Quote Link to post Share on other sites
