pulling liners on a c12, any tips?

We have no liner puller at our shop and i dont wanna wait for my service manger to decide when he wants to buy the tool...any tips or tricks? i was told by an old timer to use a wood dowel and beat it from underneath, the liners are junk anyways and the dowel is oak so its hard but not hard enough to do any damage...i know someone on here has to know of a trick.

 

haha we are a peterbilt dealer!! yea i was thinking of using a bottle jack and a piece of wood, i removed the oil tubes so ill try the dowel and hammer idea cause im thinking i can pop the liner enough to be able to go up top with a pry bar and pry the rest our and if that dont work ill bring in the bottle jack.

 

yea ive pulled them out using a puller at a previous dealer but i guess using the puller made me think theyd be really hard to pop out without the puller...thanks guys monday morning ill get those liners out

 

Haha I hear ya! Which is why Monday morning I got an interview at cummins. Not only do we not have proper tools we don't have heat! But this is why I posted on here to see if anyone had any advice for a safe way to pull the liners and I mean if it works it works and i will get the job done right and the truck will be running like new
