bobrick Posted March 6, 2010 Share Posted March 6, 2010 hi guys need another bit of advice all was going well down in the workshop today, untill i decided now would be as good a time as any to torque up the crankshaft bolt some 330 nm i think (and loctite) well i didnt get that much torque on it as i forgot all that was preventing rotation was the fuel pump timing pin, the result is that i think the timing has slipped a bit, then i noticed diesel (or what looks and smells like diesel) leaking from the front out of the breather hole in the timing chest, and now i cant get the nut undone questions are firstly, where is the diesel coming from and have i fuc@@d up my engine or fuel pump timing thingy secondly how can i undo the nut without spending 80 quid at difflock for the restraining tool. i dont want to spin the engine on the starter motor due to any possibility the timing may be out (although i have removed the rocker shaft to hopefullly prevent any further damage i belive the valve springs force all the valves closed and away from danger could someone please confirm this? cheers for looking and i hope you guys may have some better news for me im usually really cheerful after a day on the truck but today im not cheers, will ralph cheers for the invite but i did not make it up that way in the end and ive only just logged on. ill give bob a ring on monday and see if he can get some in for me next time im up there Quote Link to comment Share on other sites More sharing options...

western Posted March 6, 2010 Share Posted March 6, 2010 OK, hopefully it's nothing serious. has the FIP timing pin damaged the alloy casing of the FIP ? if no damage easily visible it might have cracked the casing allowing fuel to escape.

reb78 Posted March 6, 2010 Share Posted March 6, 2010 I wonder if its caused some damage inside the pump where the pin has been forced - hopefully not. Anyway, have a look at my posts in this thread - http://forums.lr4x4.com/index.php?showtopic=38651&hl I knocked up a tool out of an iron bar to lock the crank - it bolts to the damper after the pulley is removed. Took about half an hour and cost nothing as it was a bit of scrap i had lying around. Hope thats some help. Quote Link to comment Share on other sites More sharing options...
bobrick Posted March 7, 2010 Author Share Posted March 7, 2010 cheers guys i think i may have damaged the alloy casing as the pin was a bit bent when i got it out. note to self be careful with a bloody big torque wrench i think i may have a while to calm down and come up with a plan and some bar to make the tool & open it all up again and assess the damage cheeers for your help will Quote Link to comment Share on other sites More sharing options...
Les Henson Posted March 7, 2010 Share Posted March 7, 2010 With the rocker shaft off, the engine can safeley be turned without risk of damage to the valves - they will remain closed. You'll have to replace the timing belt now - it will have been stressed beyond it's design limits. Assuming that the injector pump shaft seal is fine - you'll have cracked or broken the casing, so the pump is now u/s. Rather an expensive mistake - timing gear should never be used to lock the crank. Les. Quote Link to comment Share on other sites More sharing options...
bobrick Posted March 25, 2010 Author Share Posted March 25, 2010 hi guys cheers for you advice, i know its been a while but bettter late than never well the upshot of my misdemeaner was that i trashed the timing pump by ripping the alloy casing round the timing pin this in turn tore a chunk of alloy out and exposed the front bearing. i have now learnt my leasson and have manufactured a tool as described in another post ( i dont know why i didnt before). on the good side of things i have managed to source a new pump for £50 bucks (serviceability unknown but ill take a gamble at that price, the seller said it was serviceable). does anybody have any top tips when replacing one of these or is it just a case of fit it then set timing as per the post in the forum and take care when torqing crank bolt (i have a tool for that now) any advice would be greatly recievd cheers will Quote Link to comment Share on other sites More sharing options...
white90 Posted March 25, 2010 Share Posted March 25, 2010 Geez bad luck! Just refit the pump set timimg as you said and once sorted crank it over. I replaced my pump when it was rebuilt after a leak. Quote Link to comment Share on other sites More sharing options...
jbs Posted March 25, 2010 Share Posted March 25, 2010 I would get it rebuilt whilst it was off for peace of mind if anything else,I used this place when mine seized- http://www.dieselbob.co.uk they were good and reasonably priced too Quote Link to comment Share on other sites More sharing options...
