ok, i found out what is wrong. broken timing belt. should have fixed long ago but that's another story. when i turn the valve train pulley it sounds smooth so i think i'm ok (as in no busted valves) all i need help with now are 2 things.

1 how do i hold the bottom pulley (crank pulley i think) still while i take off the big main bolt?

2 how do i line up the valve pulley and the crank pulley when i install the belt? i already noticed the valve pulley has a white dot on the rim of the pulley, i'm guessing this gets put at the top or near some other mark. now the crank pulley must have some similar mark that gets lined up with???? something?? some other mark??? i'm so close..... thanks for any help.

get a book or look on forum (i think in garage section) to see what marks look like and how to line up. If you have red engine you should be ok. The early cars you remove the 10 mm bolts to remove pulley. The later cars you use a special wrench, or a impact gun, or hold flywheel in place. Tool is a little pricey at ipdusa.com but available.

 

thanks, i found some good info searching online about the marks. i have an automatic transmition 88 240 DL wagon so i can't use the gears to hold the flywheel. i have an interesting novel idea to try and i'll post it if it works.

 

Remove starter motor and jam the flywheel with a large screwdriver.

 

WOW, nobody even recommended the rope trick? Take out the #1 spark plug, rotate the engine around to TDC COMPRESSION, back it off just a little bit and then feed in enough cotton clothesline to fill the combustion chamber and now crank the piston up so it smashes the cotton rope against the cylinder head and the closed valves. This will allow you to pop the crank bolt as well as torque it back down when you are done. I have always had a shop and air tools at my disposal so I have never had reason to use this method but there are plenty of DIY Volvo owners out there that swear by it.

I have a 1982 turbo that i have been working on on and off, one day i tryed to take the crankshaft bolt off so i put the tranny in 1st and tryed to turn it with a wrench and a pipe on that wrench for more leverage but it just felt springy dint want to do it to hard.

Was i doing the right thing? should i just try harder? or am i doing something wrong? cause i just got my head machined and am hoping to replace the timing belt next week

and whcih way should i be turning it is it the regular *righty tighty lefty loosy*

 

It is a regular bolt turns the normal way.
Try a little harder.

 

Ok thanks

 

I used the rope trick last night and it worked great!
