Bugger, A bit more terminal than a crank seal

I made a simple gadget that allows the timing cover to be removed while the bottom pulley is still in place ,this made timing belt idler and tensioner replacement a 1 hour job instead of 3 hours.

That happening in less than a second would indicate a problem that was already there in over 40 years in the trade that to me would indicate that the pully was already loose or it had had a dodgy repair previously but I'm not an expert just my experience with them

How do you take the front cover off without taking the pully off its a one piece cover that goes around the pully isn't it you'd need to cut it wouldn't you

I cut the cover leaving a small amount connected at the bottom pulley. I made a clamp arrangement which pulled the cover together when fitted. The cut was not a straight cut . I had a fleet which required each van to be done at about 9 monthly intervals with minimal down time. I only have 2 of the older 3l vehicles now and they are for backup only. The new 1kd,2kd engines are a vast improvement for timing belts.

Keep an eye on the glow plugs from memory some had ceramic tips had a few come off if your really lucky you get away with a new piston and rings but sometimes it stuffs the bores
