Need 740 B230F engine parts

I need some timing belt- associated parts for a 89 Volvo 740 GL. It
has the non-turbo B230F engine. The most urgent thing is a new
crankshaft sprocket (for the timing belt). That's the sprocket behind
the crankshaft pulley. Need a complete one, with front and rear
guides, and also the crankshaft key underneath. It has a half-moon
shape. Have already obtained a new crankshaft pully/vibration damper.
The sprocket parts and key will get it going again, but I also need a
camshaft sprocket cover& bolt, both upper and lower timing belt
covers, and a idler (timing belt) tensioner.
I checked the local junkyards, they don't have any Volvo 740s, and
the network didn't locate any of these motors designated "for parts
only". Thanks.

 

Try the yards for 940 parts for the same engine.

All the best, Peter.

You can get the parts you need off a '85 or later 240 as well, they're a
bit more common.

 

Commonly available at U Pull It Damascus in PDX.

 

The car suffered a crankshaft pulley failure months ago, Got it going
again with a new crankshaft pullley. When I took that off and checked
the crankshaft sprocket, I found that there was a little fragment of
what was a key in the crankshaft keyway. Well, there is a square
projection on the front of the sproket which engages the corresponding
keyway /slot on the crank pully. On the back side of the crankshaft
sprocket there is a corresponding dimple and some little thing, maybe
a "bump" projection was there, that has broken off. But I don't see
any slot running axially on the ID of the sprocket which the
crankshaft key would engage! Doesn't make sense. I don't see how the
crankshaft key was positively set/anchored to the camshaft pulley and
sprocket, there would just be the tension of the pully bolt. But I
figure getting a new sprocket and key should solve the mystery and fix
it. The Haynes illustration isn't clear or detailed enough on this.
Thanks!

 

The crank sprocket has a block (key) molded to the front half of the
sprocket inside of the bore. The tang on the front of the sprocket
engages the damper pulley when installed.

The goal when driving is to miss the maximum number of objects.

 

Thanks...yea, now I understand. I looked closer at the inner bore of
the sprocket, and there WAS a molded-in rectangular key on the inner
bore of the sprocket that has broken off....there never was a separate
key. Now...good luck ever finding a new crankshaft sprocket! I have
come up completely empty-handed trying to find B230 engine parts in
the local yards. Of course they have complete used engines they are
willing to sell me!

 

take a look at this:

maybe you could try the same

That trick works for the key on the *front* side of the sprocket that
engages the crank pulley, but it wouldn't work for the other key---
the one that is broken on my sprocket---the one on the inner bore of
the sprocket which engages the crankshaft. That is a site with lots
of good info----thanks, I bookmarked it.

 

I know someone who's parting out a B230, email me with your email
address and I'll put you in touch.

 

The part number is 1336927. Dealer list $46.26

Groton Volvo $35.00

What about checking your local Volvo car club ?

 

Yes I could part out the engine from a 1987 240 B230F (I believe) I want
the upper part ( cylinder with camshaft but probably don't require to
keep the bottom end - it works and is running now with about 190,000
klms on her (parting out due to subframe rot not any other reason) also
good running transmission (sorry it's a P R N D 1 2) a lot of you
enthusiasts enjoy the manuals eh! but even had a recent flush fill of
transmission fluid for those of you who don't like shifting gears
yourselves. The car is in my complex in Mississsuga Ontario Canada - I
have to work outside for the most part so think about it quickly as I
will not be hauling these things out in subzero temps outside

thanks,
