110landy Posted May 15, 2010 Share Posted May 15, 2010 hi all about one week ago i noticed the crankshaft pulley had a bit of play so i said id investigate it, ive been stripping my way down to the pulley every evening and just got the pulley off today the woodruff key has made its mark on the left side off the key hole now it looks like i could fit two keys in there one the right way in and the other upside down :( so ive ordered a new pulley and key but i have no idea what to do with the key hole so im hoping some one here has experienced this problem and was able to solve it, im going out to take some photos now so i can give you a better idea of this mess im in liam Quote Link to comment Share on other sites More sharing options...

Andy Posted May 15, 2010 Share Posted May 15, 2010 You could try to repair that with chemical metal. Take a lot of time degreasing & cleaning the crank first though or it won't stick. Or maybe drill though the pulley & crank to fit a pin to take the loads off the key. Quote Link to comment Share on other sites More sharing options...
simonb Posted May 16, 2010 Share Posted May 16, 2010 The reason why the slot is worn is probably due to the pulley not being done up tight enough. The torque on the nut should be what actually holds the pulley in place. The key is used for location and should not be taking any great load. What does the slot in the pulley look like?

Badger90 Posted May 16, 2010 Share Posted May 16, 2010 my mothers 90 has had that problem, the pully was still done up tight, must just of been wear and tear, i used the chimical metal on the, i stuck the woodruff key in with the chimical metal and let it set,, has worked a treat. as long as you get the key flush with the flat side that has NOT worn cheers sam Quote Link to comment Share on other sites More sharing options...
reb78 Posted May 16, 2010 Share Posted May 16, 2010 Is there any way of repairing the wear on these with weld? Could weld the key in (probably not recommended) or fill the worn side with weld and re-shape it with a dremel type tool so the key fits tightly again.

Giles tout terrain Posted May 16, 2010 Share Posted May 16, 2010 I have a piece of Brass the same size as the key, when i repair these i put the brass where the key should be and then mig it up and grind it back carefully Quote Link to comment Share on other sites More sharing options...

Should think that works a treat. Quote Link to comment Share on other sites More sharing options...
rovernut Posted May 16, 2010 Share Posted May 16, 2010 a whole new crankshaft????????? here s the pics That is exactly how the crank ended up on a previously owned 2.5 TD. I bedded the key in with liquid metal and re fitted the pulley. You may want to change the seal while you have it apart because the pulley wobblig around may have damaged it. Mine went on for a couple of years and for all I know may still be going. Quote Link to comment Share on other sites More sharing options...
T1G UP Posted May 16, 2010 Share Posted May 16, 2010 recently repaired mine as the puley had come loose resulting in injector pump timing issues etc. I used araldite to secure key, then filled the dent up with araldite and when set filed it back. All good after 2,000 miles or so. Quote Link to comment Share on other sites More sharing options...
