Tappet Covers

(1/3) > >>

andut:
Anyone else had tappet covers seize and if so is there a trick to get them free ?  Most of them behaved, but I've managed to round off 2 that don't want to play - bloody ally caps are as soft as cheese !

Tried to get some purchase with a screw driver on the wide edge of the cover, but I'm now breaking the cap into pieces.  Is this familiar to anyone ?  I'm starting an engine rebuild (first) so how important is it to loosen tappets before lifting the rocker cover ? 

Thanks for any help / guidance !

These are sometimes a pig. You have to put a ton of heat to get them moving sometimes, i have even had to drill them out. Take the rocker cover off and you will stand a better chance.

Thanks Trigger - glad it's not just me !

A while back yours truely restored a 400/4 stripped it all down blasted in some form or another to finally reasemmble to find out after relpacing the tappet covers could not get the frackin things back off without destroying the threads on the cam cover.Discovered that and did not make the same mistake with my 750s is NEVER ASSEMBLE ali to ali without grease if you do down to you.

 I recently bought a couple of caps for my 500 from DSS,I got the pattern ones,turns out they are slightly deeper,
when I removed one to check the tappet,I noticed a mark were the rocker had been hitting it,

BTW,they are damn expensive !!!
