Timing chain

[meganwilkinson2008]

Hi back again, I managed to get my pulley off and change the timing chain but i'me a bit confused about the oil thrower washer I had in the kit. can I use the old thrower as the one in the photo only fits over cam and not crank. Also I have noticed the oil seal supplied keeps pushing out is there anything I can do or is there a better seal I can purchase or is it just me been stupid thanks.[frame][/frame][frame][/frame][frame][/frame]

Your 'new oil thrower' is not that at all - it's a replacement lock washer for the pulley bolt/starter dog
When replacing the lock washer, make sure you knock it back both ways (ie into the pulley and over the starter dog). Assume you know also to centralise the timing cover with the crank pulley before tightening the cover bolts too?

OK many thanks trouble is the hole in it doesn't allow you to push it over the crank,in the third pic when ime holding it that is as far as you can push it on.is it still OK to use the old thrower with the duplex chain ?.I don't want to tighten everything up til I get it right thanks.

You have the right oil thrower for use with the duplex chain and later type lip seal.
Make sure that the 'F' on the newer type oil thrower plate is facing FORWARD as that is what the 'F' refers to.
As regards the lip seal being pushed out - do as Chesney says above - in that having pushed the lip seal fully into the timing cover (lip seal/spring towards the oil thrower plate/inside the timing chain cover ; fit the timing cover with the retaining bolts loose and then fit the crankshaft pulley - turn the crankshaft to centralise the seal and timing cover. The crankshaft pulley will have then centralised the oil seal/timing cover - when centralised progressively tighten the timing cover retaining bolts.
P.S.
Did you align the teeth of the cam gear and the crank gear using the shims at the rear of the crankshaft gear.

Just ease the hole out slightly till it does fit over the crank. You need to just tap the seal in carefully all the way round, little by little. can't see the two screws - hopefully you countersunk the holes enough to get the screw heads flush with the front plate.

Great thanks for all the help.Yes i have countersunk the screws level with the plate and made sure that it doesn't catch.when i took the old chain off there was no oil rings or shims.it does look that thay are level now ive put the new ones on.I did check to see if it was level before i removed the old one, but to me it didn't look level when i put a straight edge on it.This is my first time on timing chain so if i sound ignorant you will have to forgive me. Do i need to put shims on if it is level ?

[bmcecosse]

No - but the teeth on both sprockets need to be exactly in line.

[philthehill]

It is most important that you correctly align the gear teeth otherwise the chain and gears will be subject to rapid wear.
To align the teeth - you need to add or subtract one or more shims between the rear of the crankshaft gear and the crankshaft.

But do check the endfloat on both crank and cam first....and (assuming they are within spec) set them both right back before checking with the straight edge.
