NEED ADVICE!! Balance Shaft Belt

Check this out..


If you look to the bottom, you can see the belt is off one of the gears.

Funny thing, I had no idea this was off, I just decided to inspect it while I was doing my power steering pump. I didn'tdrive poorly or what have you.

ADVICE NEEDED for:

Where would you recommend I get this new belt (balance shaft)?

I was inspecting the timing belt (which looks brand new actually) and it was not tight to the touch. I could move it quite easily.

Off the top of your heads, how tight should the belt be to the touch? I know I need to get it adjusted, but I am wondering if I should tighten it a bit before I drive it to a shop.

Thanks

Lucky guy, go buy a lottery ticket.

When the BS belt comes off it usually take the Timing belt with it. Do not drive it anymore until it is replaced. Looks like it's frayed as well.

Pelican Parts would be a good place to buy your belts.

Belt is junk. There is a huge piece of it that is torn / hanging. Obviously, the belts were not "checked" as the PO informed me.

Just ordered both belts and the tensioning tool. Found some great documents on how to replace the belts and proper tensioning and so-forth. Should be fun. Maybe I will take pictures as I replace / tension the belts.

Thanks.

Do so. There is much "lore" about proper tensioning and retensioning of the belt(s)

Close one! You might as well seal up the front end while you are at it. Replace the belt(s) rollers/ guides, maybe the H2O pump. You got lucky, very lucky.

I do have to find out why the belt "fell" off one of the rollers. There is something else at play here. Maybe the chunk of teeth that are missing from the belt helped it slip off and not break?

I'll post some pictures of when I do the job and my results.

You will definately have to seal the front as there is oil over everything. This could be the reason the belts have deteriorated. Also plan on replacing any roller that even feels like the bearing in is bad. Most just replace these anyway. Especially the toothed tension rollers.

I've had a balance shaft belt break without taking the timing belt with it. Engine vibrated something awful.

When was the last time you changed your timing and balance belts and/or cam chain and tensioner?

The oil you see is from the leaking power steering hose. It took me a long time to find out exactly where the leak was. Its all over the engine.

The previous owner actually did have one good thing done. He had the head removed polished and some valve work done. I have the reciept for 1200. I'll order the pulleys too.

I think I might be close to driving this thing, although I have said this before.

How does power steering fluid get into the belt cover????

Better seal the balance and cam shafts.

IF PS fluid did get into the cover that is worse than just engine oil.

PO left a couple of screws out of the cover, guess that is how it got in there.

I would investigate a little more.


I am going through something similar with mine.

Just opened up the belt box a few weeks ago to check things out and my balance belt was gone and the timing belt was only half there.

The deterioration could very well be from a seal leak but that looks a little like fraying. That seems to indicate a little rubbing here and there.


BTW - I think my condition was from a rear cover bolt that backed out.

If you look at the picture above, what happened is the belt was probably NOT adjusted after 1500 miles and was a bit loose, then the addition of a slippery liquid, caused it to slip off (picture) then there was enough tension still to rub against the gear and fray the side.

I have no idea if this is really the case, but that is my thought.

I know people are going to beat me up on this, but I don't think the belt is going to be that difficult. I have done timing chains in the past, this can't be much worse.

Either way, I am going to find out.

Thanks for the information.

Belts are not that difficult.

You just have to be patient and pay attention to small details, much more than a timing chain.

If you need help just do a search or let us know.
