Grayracer - thanks for the tips. Sorry, didn't mean to hijack the thread, but the OP went straight onto countershaft seal removal in the opening page. 066logger - advice on removing the collar was a couple of pages earlier. Think it was tribalbc who mentioned removing the seal makes the collar pop out as well, or something like that. Might have to go back a couple of pages. Just picked up parts this morning. Glad they had them in stock, as got a ride this afternoon. Thanks to all for their help.
