Hey guys,
Ging's husband here. I just have a quick question but maybe a long explanation. We are removing the crankshaft from 'her' 70 GT (1.9 L) to have it polished and install new bearings. The manual states that I must remove the head in order to remove the timing chain. Is that really necessary? Could I just remove the timing chain and sprocket from the crankshaft and leave all the other pieces in place? I have, at this point, not removed the timing chain cover.
Another question. The 'serrated drive' used to remove the camshaft timing sprocket does not seem to be the same as the 'star bit' drivers available at the local auto parts store. The set I bought today have a cross section of a six (6) pointed star. The closest fit was (I think) T45 and still I couldn't loosen them without it slipping. The bolts I am to remove have more 'points'. Is this a tool I need to get from a dealer or a specialty tool store? The manual does list a part number for the tool but this is after all a 34 year old book. This is my main motivation for the first question. Is it necessary to remove the head or can I slip off the chain from the bottom?
AND, if I DO need to remove the head will a T55 driver work as a 12mm serrated driver for removing the head bolts?
Wow, what a mouthful.
The wife says hello to everybody
Thanks
Ging's hubby (aka. Dan)
