4ac - How To Remove Crank Timing Pulley

[slapper]

any bright ideas?

 

The front oil seal is spewing oil at an alarming rate and needs to be replaced.

Standing between me and DIY progress is the crankshaft timing pulley - which I can not pursuade to seperate from the crank.

 

 

hellllp!!

Hey mate,

Had the same problem a couple of months ago when my seal went. We ended taking an oxy to it and slowly heated it, then got a large flat screw driver on each side and slowly levered it off. We had to stop and reheat it a few times but persevered, once its off enough we used a Pitman Arm Puller (if you know what it looks like) we just hooked it on behind it and slowly worked it off.

Hope it helps.

Hi Slapper

 

Can you tell me which way (left or right when looking at the bolt) the crank bolt comes undone? I have the same job to do and nee to know this before I spend 1/2 a day trying to tighten the bolt up (rather than loosen it off).

same as all bolts on your car

 

anti-clockwise to undo

[philbey]

lefty loosy righty tighty :P

 

As long as your spanner handle is UP.

[slapper]

thanks to all that have responded.

It sounds like perseverence is the order pf the day.

 

currently soaking with CRC and working away at it.

 

foc64 - anti-clockwise looking from the front to undo as has been indicated ... same as normal.

 

cheers,

heaps of crc and sand any rust off the front, careful with any heat though as you can weaken the crank if you get carried away. Don't laught, but I did use a hairdryer once and no shit it worked. Took a long long long long,.............you get the picture.

 

ummm, I used a candle once.

 

The stuff that I found to helps with glues, oils and silicones is carby cleaner.

Left-hand thread

Not right-hand

Otherwise the bolt will undo itself while the motors running

i assume there's no holes in it, make your own.

tap them out and use a puller.

that would probably weaken it, and you'd have to rip the engine out to drill them properly wouldnt you? there isnt much room.

 

and as i said when we heated we just sorta flamed it slowly to generate some heat, didnt let it glow red :P

nope :P

engine runs clockwise (looking from the font) and the bolt is indeed an ordinary, run-of-the-mill, bog standard, everyone's got one, vanilla, nothing special, middle-of-the-road, pleasing to all, unambiguous, non-perilous, right-tighty, lefty-loosey right-handed thread.

 

ie. turn it clockwise to tighten, anti-clockwise to loosen.

Handy ... cos splotting a spanner on the bolt head and jamming it against somnething allows you to use the starter motor to crack the bolt open.

 

Hurrah hurrah - pulley has now been removed, everything has been dropped, cleaned (a bit), new seal installed and shoved back together. Now I have no excuse not to go to work tomorrow :D

 

a CRC spray every 15 miunutes, heating with a butane torch every now and again (don't know whether that helped or not) ... a cold chisel wedged between the pulley and the oil pump on the left (there's a ridge you can pivot on) and liberal "heavy tapping" of the chisel to see-saw the pulley off slowly but surely did the trick until there was enough room behind the puley to get an ordinary three handed puller onto it. Took me a couple of hours of patient slow-and steady work ... Crikey - goes back together bloody easy though!

 

cheers,

Slapper

I had to do this. Get yourself a proper pulley puller to pull the poofter off perfectly...

 

 

Say that 10 times fast :P

Cheers Guys

 

I had a feeling the crank bolt was a left hand thread, but seams I'm wrong. Looks like I'll just need a longer extention bar on my socket (the 4 foot long pipe I've used before works a treat - thank God for old school Sidcrome tough as nails socket sets).
