Is there anything apart from the screws holding the timing case on. mine doesnt seem to want to come off, pazon ignition , I am rebuilding the gearbox and decided i might as well get ome bling happening by polishing all the cases while its apart
thanks for looking
 
Nope, there are 12 screws holding the timing cover. Often the gasket is glued to the crankcase and cover so you may need to work a thin, sharp blade around to break it free.
 
There are also a couple of dowels that often stick a bit, tap it with a plastic mallet and then as Ron says use a thin blade to ease it off.
 
If the oil junction block is off, you can give the rear of the pressure release valve a couple of firm taps with a length of 1" x 1/2" hardwood from the drive side which is often enough to get it moving. If it doesn't move though, don't keep smashing at it as you could knock the cover out of square on the dowels.
 
You did remove the ignition rotor from the end of the camshaft, didn't you?
 
And you do have the service tool for protecting the new seal at the reinstall? And of course you have found a new pioneer brand seal for the crank end. And a new gasket It's the while your at it's that drive the price up.
 
While you are in there:

be advised that there are differences in the thickness of the timing cover gaskets out "there." The clearance can be critical for the amount of compression of the "button" seal for the oil pump outlet.

You will also need one of those.

You also might want to check the oil pump. It is an easy task to lap it in and make sure that it will work well when you tighten those cover screws back up.

You will also have to set the static timing once you remove the trigger.

Removing the timing cover is so much more than the polishing but it is all fun! :wink:
 
Got it off, It was glued on,And all i wanted to do was polish the case, its turning into a marathon, Gearbox cases etc are off and i plan to rebuild the gearbox while its apart, Will look at the oil pump while its apart, hopefully the other seals etc will be ok when i put it back together , Being in Oz i have a couple of weeks lag time by the time i realise i need a part until i receive it so often when i pull things apart i have to consider to wait or go with what i have

I used a nice sharp putty knife and hopefully you didn't slash your hand open like I did.
 
I'm up for this soon, to install (at long last) the automatic cam chain tensioner that's been gathering dust these last few months...so if folks have part numbers or other helpful hints they will be much appreciated...

Heck, I may even polish the cover while it's off.... NAHHHH!!!!
 
Timing cover

Before re-installing the timing cover check to make sure all the alignment dots on the crank pinion, intermediate pinion and camshaft pinion are properly spaced. Every time I take my timing cover off the pin through the intermediate comes with the cover, the camshaft then slips and the whole thing goes out of alignment.

Before applying any gasket sealer, push the cover up with gasket in place. It should not be able to seat to the crankcase as the oil pump conical seal needs to be compressed. If this is not the case, you will need some shims under the oil pump seal. This takes care of any variation in gasket thickness.

Try using a retaining compound on the end that fits into the case (i.e. Loctite 648 Hi-temp). Next time the intermediate gear shaft will stay in the cases.
