they look thusly

thanks for the post on this
Anyway the question i have is the locking bolts the same for a auto?
I would assume they are but to assume is to make an ass of oneself.

too easy, yes the pins are the same.

There are other means available if you dont have the access to the pins or the ability to have them made accurately.

to lock the crank you can make use of the access holes for tightening the flex plate-TC mounting bolts.

Thanks for that. I have 2 lazy fitters with a lathe at work so im sure i can get them to turn them up for me.

with the sludge box...

its a good idea to check the condition of the TC mounting bolts at the same time as the timing belt.

The following is for the desparates out there such as myself, who in this case had left sourcing tool parts to the last minute.

In the last few days I attacked my timing belt, first time doing this. Figured I'd make the timing tools, the 3/8th for the pump was easy, regular Champion HT bolt (which you can get at the auto shop) with the threads cut off. But, being complacent I was sure I had an M14 bolt around the workshop somewhere, but no go, not one. by now it was a public holiday and I really wanted to get the job done, nowhere to get an M14 x 1.5 bolt. My vehicle is an auto, so has the side plate on the bell housing. The big bolt on the plate is an M14 (duh of course it is you all say). Anyway, having discovered this I was happy, as all I had to do was drill a hole through the centre and tap a 10/24 thread in it (for the 3/16th inch bolt I had - but an M5 would have been OK too I guess), thread in the bolt, put a washer and a couple of nuts on it, cut to desired length, and presto a nice timing tool for locking the flywheel. It did work nicely, I followed Dave's tutorial which was invaluable to this first timer thank you.

Great Tutorial Dave.

your welcome but really its what the forums here for and the way I it figured is that you the taxpayer funded my skill sets, its my job to make sure you get your moneys worth.

Thanks for this. Just did my timing belt for the first time. Made it a lot easier, following your tutorial.
