Starter does not come off while trying to replace it

[nagh1610]

I am trying to replace the starter on my SV21, 1990, Toyota Camry, 4 Cylinder car. Rather, I am trying to replace the solenoid contacts as I have got into the intermittent problem of ‘clicking but not cranking’ which has been dealt with excellently in some posts on this forum. I have read those. I have removed the two connecting wires to the starter and the and the two long bolts which mount the starter on to the engine/body. But the starter is not coming off. It does not budge even a quarter of a millimeter. Are there any more bolts/nuts which are not visible that I need to remove? There are no visible nuts/bolts anywhere, probing with fingers under the starter does not indicate any presence of any nuts/bolts underneath. How do I get the starter out?
Please note that I had been to a wrecker’s yard to get replacement starter and there I had no difficulty in getting the starter removed after taking out the wires and the two bolts. So “I have done it once”.
Now what could be issue with me starter not coming off? Please help.
Thanks in anticipation.

It's just those two bolts. I had the same problem when I was changing my starter. You'll just need to tap the body of the starter to loosen it. "Tap" here means start with a gentle one with the handle of a hammer or wrench, then maybe a little more back and forth to break the "seal".

Thanks for that. I will give it a try. But it is stuck real hard, I have tried a lot force with both hands and tried lifting it using a sling made of rope, does not move a quarter of millimetre also.

have you used a hammer ? but there shouldn't be anything holding it on other than the 2 bolts.

Thanks nopain and atobe for your replies. I bought a set of 3 cold chisels and hammered them in. It need persistent and forceful hammering before it moved, even afterwards took a lot of hammering with two chisels stuck on two sides. All that hammering cracked the starter casing.
Now my next problem is bench testing the replacement starter I have got from a wrecker. I wish to do that before I put it in the car. How do I do that? I connected battery –ve to the body of the starter and battery +ve to the copper screw (to which the car battery wire was connected). Nothing happens. If I connect +ve battery terminal to the covered thick wire on the opposite side then the motor spins but the ‘bolt/plunger’ does not jump out to engage the flywheel.
Do I need to connect the +ve to the copper screw as originally done and also make a connection from +ve battery terminal to the brown/black terminal on the starter (where the other wire in the car was plugged in). How thick this wire needs to be? For copper screw and starter body I am using 200AMP jump starting wires.
Please help.
PS : I opened the cover and the contacts look worn out anyway. I will buy a starter kit and replace them as suggested in various threads. But would still want to bench test after fitting the new contacts.
