D2 drama's and advice

[discoduk]

Today while on my way home from long weekend getaway the disco cab started to fill with smoke, pulled over and discovered the bottom main crank pully was wobbling all over th place and sqirting oil all over the manifold and so on. Tried tightening it up and it did nip up some but still wobbled heaps and was going to spit the belt off easily. so got it towed home. i'm guessing the front crank keyway is nacked hence causing the pulley to wobble and has blown the front seal.
Is this a big job?
How much stuff do i have to pull out to be able to do the job?
Or is it a workshop mechanic job?

Any advice would be appreciated

G'day

I would ordinarily try most mechanical repairs myself, even if just to strip down and rebuild to save mechanic's labour costs.

If it were me, I would determine if the keyway has had it first.

If you are lucky, it may be loose bolts or some other minor cause. You may have to strip the stuff away from the fan cowl/radiator area to get good access.

If it is the crank keyway, I wouldn't touch it with a barge pole. Take it to a mechanic and get second mortgage!

Sorry!

Does the pulley actually move/wobble or does the whole thing vibrate when running.

The reason I ask is the my MicroCat for that motor indicates there are a series of balancing weights that you can buy!

Maybe your's has thrown a weight!

Also, MicroCat lists the pulley as a "Damper Assy" so, maybe. it's like the Commodore harmonic balancer assy and is a bonded rubber thingy prone to cracking. If they go, and they do, they vibrate and knock like buggery!

Just a few thoughts.

I feel your pain!

I haven't done it myself but I'd certainly be pulling the fan and radiator and having a good look at the harmonic balancer before taking it anywhere.

The balancer is known for having the outer move out of position and making the timing marks useless.

If you are near Bassendean, I can look and check it out

[discoduk]

Yea it did wobble and knock a fair bit and oil was squirtin out of the seal. And was about too spit the belt off so i will get the radiator fan and cowling out of it and have a better look whan i get home from work, which is not for another 2 weeks, had a trip planned too for then but looks like i wont be doin that now.
Hopefully it is like you say and the harmonic balancer with a know fault ( thanx guys ) thats the problem, if the crank is damaged stay tuned for a wrecking disco. i'll keep yous informed

[discoduk]

not sure where Bassendean is but im in Padbury, thanx for the offer Mike. i'll check it out and get an opinion

[discoduk]

well i just pulled off the pulley, slipped the belt off and got underneath and un bolted the the whole assembly, looking at the key way it looks like it has slipped out 10 mm or so and then worn left 10mm then slipped again 10mm and worn left 10mm, it also has two missing bolts that attatch the weighted part to the rest. so it has a stepped look to it. I cant realy geta good look at or into the key way on the crank but no visible carnage. my guess i think is that maybe it was out of balance because of the missing bolts and in turn loosening the the main bolt and wearing and slipping worse as it mov ed away from the seated position. What do you guys reakon? should i just source replacement parts and refit and see how i go?
