K Series Apollo sandwich plate removal?

[Grant Dryburgh]

Hi folks, 

I found a crack in my oil filter housing the other week, got a new housing ready to go on but before I set about pulling the old one off just wanted to check regarding the sandwich plate. 

Is this likely to be mega tight or should it be easy enough to free from the housing? 
 

Any tips on how to actually go about cracking it loose from the filter housing ?  
 

Assuming on re-assembly it will be the same as any oil filter just nip it up hand tight? 
 

Thanks in advance for any help

It has to be tighter than the oil filter. If not theres a risk it parts there rather than at the filter where it's supposed to.

The sandwich plate doesn't unscrew from the housing as the filter does; just the threaded centre piece. There's a big threaded "hollow bolt" (for want of a better description) that screws onto the thread of the housing, clamps the sandwich plate in place and in turn has a male thread for the oil filter. It should reasonably tight but shouldn't be a problem to undo.

Perfect thanks Andrew
 

I assumed it was just spun on the same as a filter didn't realise there was a bolt on adaptor, got it all off no bother just need to clean the face of the block for the new housing gasket and bolt the new one on

Maybe prudent to get a new sandwich plate rubber ring. They go hard with heat cycles and lose their sealing properties once opened up.

Agree with Wrightpayne. Get a new sandwich plate seal. They are only cheap. I doubt you'll get away using the old one and not having one will delay what is a small job.

Cheers guys, seal looks ok but I'll get a fresh one ordered anyway
