Puffernutter Posted September 27, 2010 Share Posted September 27, 2010 I have a piece of round bar that fits into a hole on the side of the fan pulley. Holding that and a sharp hard strike on the spanner (on the fan nut) will normally loosen it. There is not enough friction on the pulley/belt to apply enough force to break the stiction on the fan nut. I can make another one up (it's a simple turning job) and send it to you if that helps.

leon_81 Posted September 27, 2010 Share Posted September 27, 2010 sharp chisel and a bit hammer does the job, just had to do my mates when changing the water pump one sharp whack will crack it, then you can spin it off by hand Quote Link to comment Share on other sites More sharing options...

Cheers Peter Hi thanks for the quick reply , where do you place the bar??? any chance of a quick sketch thanks john Quote Link to comment Share on other sites More sharing options...
Puffernutter Posted September 27, 2010 Share Posted September 27, 2010 Hi thanks for the quick reply , where do you place the bar??? any chance of a quick sketch thanks john No sketch at the moment, but if you look on the side of the pulley there is at least one, if not two holes at 180 deg apart. They are about 1/2", (maybe less) from memory. BUT, to make it work, it needs to be a reasonable fit, otherwise it will just fly out. That's why I turned one to a close fit.

Puffernutter Posted September 27, 2010 Share Posted September 27, 2010 Hi , dont understand what holes that you mean? I have a 200TDi Defender engine, but the front of the Disco is no different. If you look on the side of the pulley that the fan screws in to, there is at least 1, if not 2 holes and they are 180 degrees apart. If you rotate the engine and look at the side of the pulley you should see them. I assume there is a proper "tool" that uses both holes so that you can firmly hold the pulley whilst beating seven kinds of cr...p out of the fan nut! As I said before, you will need a sharp "crack" to break the stiction on the fan nut, the trouble is that the pulley will always slip slightly on the belt and most of the "crack" effect is lost!

Puffernutter Posted September 27, 2010 Share Posted September 27, 2010 Hi , again there are no holes apart from the 3 screw holes that bolt the pully on on my disco? Not on the front face, but on the edge of the pulley? Cheers Peter Quote Link to comment Share on other sites More sharing options...
Puffernutter Posted September 27, 2010 Share Posted September 27, 2010 Interesting, I will have a look at my engine when I get home in case I'm getting confused as to which pulley has the holes in - could it be the crank pulley?

Puffernutter Posted September 27, 2010 Share Posted September 27, 2010 In that case, can you get a webbing strap (the sort you can use for oil filters) and restrain the pulley that way? Cheers Peter Quote Link to comment Share on other sites More sharing options...

Cheers Peter Hi , tryed that alreay , and a rachet strap , just about everything at my wits end now , just want to get on and do the job ( need me landy) and stumped at the first hurdle , soon the grinders coming out and goodby fan Quote Link to comment Share on other sites More sharing options...
moose Posted September 27, 2010 Share Posted September 27, 2010 hmmm you can do the job (on a 200tdi) with out having to take the fan off just unbolt the water pump with it still on... have done this lots times when i couldn't get the fan to un-screw.. simples Quote Link to comment Share on other sites More sharing options...
PaulN Posted September 27, 2010 Share Posted September 27, 2010 I was gonna say you could sacrifice the pulley by drilling through 1 two ho;les opposite one another and then use a bar but then read Moose's advice and would definitely go with that to get going.

boneheaddread Posted October 2, 2010 Author Share Posted October 2, 2010 Hi , again , well after a stuck fan nut , several rounded off water pump , timing cover bolts , and very very stubern crankshaft pully bolt I got to the cambelt , it was not snapped but corroded or rotted away it was still in one piece but missing at least half its teeth , and the inside of the timing case was full of a black shredded furry mess ??? would this be due to oil leaking into the case , fuel or water ??? I dont want to rebiuld with a new belt until I can find out why its rotted away? any ideas or reasons what can cause this thanks john Quote Link to comment Share on other sites More sharing options...
Les Henson Posted October 2, 2010 Share Posted October 2, 2010 Belts don't always snap - sometimes they just shred teeth. If there's oil in the timing case, then possibly the crank front seal (not the timing cover dust seal), camshaft oil seal, or seepage from one of the bolts that pass right through the timing case and into the engine block. Les. Quote Link to comment Share on other sites More sharing options...
boneheaddread Posted October 3, 2010 Author Share Posted October 3, 2010 Hi , just had a good look at all the seals and the leak seems to be fuel dripping from the injector into the timing case , is there a replacable seal in there ????

Les Henson Posted October 3, 2010 Share Posted October 3, 2010 You mean fuel leaking from the injector pump shaft seal? (behind the sprocket that the belt runs on). Yes - this is replaceable with the belt/pulley removed. Les. Quote Link to comment Share on other sites More sharing options...
boneheaddread Posted October 5, 2010 Author Share Posted October 5, 2010 You mean fuel leaking from the injector pump shaft seal? (behind the sprocket that the belt runs on). Yes - this is replaceable with the belt/pulley removed. Les. Found a place today not a mile from my home today that can supply and replace the seal on my injector pump for £25 , hopefully that will sort that ,so why I am waiting for that to be done I will strip off the timing back and replace the gasket and both crank and cam seals as well , Quote Link to comment Share on other sites More sharing options...
