Volvo Maintenance Hints for 7xx/9xx - Bill Garland's Nuclear ...

the rope and jam the piston. Tighten and torque the center bolt following the "torque and
turn" procedure.
● Remove the rope, install the plug.
Pulley Removal. [Tip from Pete Fluitman] Once you get the bolt off, the pulley will just come off
with a little persuasion. Don't get violent with it though. Usually as I'm facing it and it is stubborn
put a pry bar on the left f the pully between it and the engine block, and on the right gently tap,
preferably with a hide hammer. Once it moves you can just wriggle it off. Or use a puller. Now is
the time to inspect the condition of the harmonic balancer rubber and make sure it is intact.
[Chris Herbst] Take a rubber mallet or a light hammer and tap the perimeter of the pulley, going
around the edge as you tap. Sometimes you can hit on it a few times in one spot, and a few
times directly across from that spot. Repeat a few times but don't smash the thing
unnecessarily. Eventually you should be able to just pull it off. You'll see it start to move around
a little bit, and that's the high sign. Sometimes you have to wiggle it back and forth a little bit as
it goes.
Pulley Installation: Tightening with a Belt. [Tip from Carl Buxbaum] After replacing my timing
belt, in order to tighten the crankshaft pulley bolt to 60N/M, I wrapped one of the old drivebelts
around the innermost groove of the pulley, and notched a couple of teeth of the belt over the top
of the water pump, where there are a couple of ridges that helped hold it there. While grasping
the belt with my left hand I was able to tighten the bolt to spec with my right without too much
difficulty. [Editor] Note that Scantech and some Volvo harmonic balancers must have the holes
filed out to fit the 5284 tool. The casting is ridged, causing the tool to shift under torque. File
square.
B230F Crank Bolt Torque on Re-installation. [Abe Crombie] Torque this bolt to 60N-m (45 ft-lb)
plus an additional 60 degrees (1/6 turn).
Timing Belt Tips in B23/B230.
Save Your Radiator. [Steve Cole] Cover the engine side of the radiator with cardboard to
prevent damaging the fins. I thought of doing this at the begining of the project, but decided to
be careful instead. After I hit the radiator fins twice with a wrench I put some cardboard there.
Aftermarket Belts? I am going to be replacing the timing belt and front engine seals, on a 91,
740, non-turbo, sedan, B230F engine. I have a few questions: Does anyone besides Kent-
Moore make any of the Volvo Special Service Tools? Are aftermarket timing belts and seals
okay on quality from somewhere like PepBoys? Will I need a Vibration Damper (Harmonic
Balancer) puller for the Crankshaft?
[Response 1: Phil] Pep Boys is not known for good belts...at least the ones I've tried. You're
better off getting a name brand belt. Both TRW and Goodyear brands both have the markings
on them and I'm sure other name brands do also.[Response: Zee] Contitech is an aftermarket
belt that my shop has used for decades. I liked the fact it had lines on it marking the positions of
the timing gears. Great help on the install. (you will only see the lines for the two top gears,
