I snapped one of the small bolts that hold the cam retainer plate and have made a mess out of trying to drill it...its doesnt seem likely at this point that i can re-thread it....i was thinking of using an arc welder to weld on the retainer but ive read horror stories about arc welding on cast iron....anyone have any input or ideas/

 

it can be done but you have to be VERRYY GOOOD! so i'd say if your anything less than a master welder then don't try it.

 

Hell no, get someone who knows what they are doing to get the bolt out and fix it. Now its going to cost more since you worked on it and made it worse......

 

follow mdactions advice. DO NOT WELD ON YOUR CAM THRUST PLATE.

 

oh god

 

any chance you can drill it out, and tap it for an oversized bolt?

 

drill it out and install a permacoil. do not weld it

 

What in the world are you thinking....

 

Wow, now I have heard everything.

 

i bet you don't do it

 

Do it and call me when you wanna take your cam out.

 

I would strongly recommend against welding it. Plus, if you need to change the cam at some point, you will be screwed...

 

holy @#% no no no do not do that oh god please.

drill it out and tap it for a bigger bolt. how did you make it a mess ?
if that can't be done helicoil.

 

welding the retainer plate to the block...wtf?

 

The motor I put together for Penz on this site had the plate spot welded on when we took the motor apart. We were both like WTF. I took a screwwdriver and hammer and hit it 1 time and it fell on the floor. I wish I would have taken a pic of it first. The guy who assembled the motr before us must have been a real idiot.
