How do you get the crankshaft pulley off a 1981 bedford CF250?

Question

I am trying to replace the water pump on my exceptionally old bedford CF campervan, and have got to the stage where we need to get tthe crankshaft pully off, but am having huge amount os problems.

how can you jam the flywheel starter ring gear when removing the crankshaft pulley bolt?

Answer 1

Things can get mighty stubborn on older vehicles. I would have thought you could put the motor into gear, handbrake on, to stop the crankshaft turning. (that's what we would have done in the "old" days lol) Use a combination of 2/3 leg puller on the pulley wheel, pinch bar/heavy screwdriver behind it, bit of heat if possible, and some judicious taps with a hammer.Heat will expand the pulley wheel. (I never cease to be amazed that a starter ring grips so tight on a flywheel, when the only "fixing" is that it is heated, expands, and then shrinks to fit as if welded on the flywheel. Did it once during my mechanic days) Be very careful with it all, too much pressure on pulleywheel, especially outer edges, may fracture it.

Answer 2

Once you get the bolt out you should use a harmonic balancer puller to remove the pulley. If you can get an impact wrench in there you can remove the the bolt without locking the flywheel. When I have to lock a flywheel I have someone hold it from underneath with a pry bar.

Answer 3

There is a tool. It has three prongs. Although I recently broke one (the crank pulley, not the tool) that was seized up from age while using the correct tool. A new balancer cost me more than I feel comfortable saying and was so very hard to find. I had to have one shipped to me from an out of state junk yard, and the first one was set up for the wrong kind of belts so I had to try again. Anyway, be careful with the amount of force. I thought about using heat to get it off. Good luck.

Answer 4

Use a hydraulic puller you can hire these, remove starter motor this will give you access to flywheel teeth you can use a large screw driver to jam flywheel.Regards Mick

Answer 5

try using a gear puller you can find them all most any where make sure you get the right one for the job and ther about 15$-50$

Answer 6

Perhaps you could use a bearing puller - or make-up one that will do the job if size is a problem

Answer 7

pully extractor and a big hammer
