Brookydave Posted May 25, 2006 Report Posted May 25, 2006 I brought my 98 90BHP tdi as a non runner. When I investigated I found the cam and diesel timing out by 1 tooth. Moved it around and it started 1st time. Went OK for a week, then the fault repeated itself. Bought a new Gates kit of belt, tensioner and idler. Went OK for a week and jumped again. I am getting quicker at belt swaps, but it is getting me down. Anybody have any clues. I have TIS, and tensioned it at correct point with nib and gap in alignment.Help please.... :16: Quote

Masked Marauder Posted May 25, 2006 Report Posted May 25, 2006 The crank pully is on a tapered seat. Don't use the car until you get it reseated correctly and the bolt fully tight. You will most likely need a new pully. Quote
Brookydave Posted May 31, 2006 Author Report Posted May 31, 2006 Thanks for replies.I abondoned the Galaxy and went on holiday in the Shogun.I have checked all the pulleys. But the slipping crank pulley is a gem, and would explain why both cam and diesel pump slip by the same amount :D At last I have a feasible explanation. As an engineer I assumed the crank pulley was keyed (I was also taught never to assume anything :lol: ). I wondered why I got a new crank bolt with the Gates cambelt kit (further embarassment).Any way thanks Masked Marauder for pointing that one out. I know what I will be doing this Saturday.Dave Quote
Masked Marauder Posted May 31, 2006 Report Posted May 31, 2006 When you consider the camshaft pulley and the pump can both be adjusted independently I can not understand why the crank pulley is not keyed either. Every other car I have owned has had a Woodruff key in the crank. Quote
Brookydave Posted June 1, 2006 Author Report Posted June 1, 2006 Pity I always turn an engine in its normal rotation. The crank pully had moved 1 tooth (marked it last time) and the securing nut was undone with a small ratchet and minimal force. Pulley came off with 2 small levers and light force - no need for a puller! The retaining bolt had picked up on crank (think it was rust holding it together), but managed to clean that up with split bolt. Will clean & regrind taper tomorrow evening. Then we will see how many valves its bent...Still at least I know what the problem is! Thanks again. Dave :D Quote
Masked Marauder Posted June 1, 2006 Report Posted June 1, 2006 As long as it has never slipped more than a tooth you should be OK. Quote
