[QUOTE="champion, post: 33008, member: 443"] Hello VOC! My father and I are in the process of putting his 'C' twin back on the road, we are putting the timing chest together and we have come across a couple of small problems. We went to remove the oil pressure releif valve out of the timing cover to inspect it. We removed the bolt with the spring attached, but the little Part:OP37 is well and truly stuck up inside. We have tried heating it, WD40 soaking over night, heating it again - hotter, soaking it. poking it from behind with a little bit of wire, heating it again even hotter, WD40. With no luck at all. What do we think? Next: last month when we went to remove the cams and followers for inspection, we removed the large alloy idler to replace with a steel one, and at the same time wanted to remove the half time pinion (ET49. It does not have the 3 extractor holes drilled into it, so we can not use a puller to get it off. It looks like a timed breather gear ET49/1 has been put on, round the wrong way instead. How on earth do you remove an ET49 without splitting the crank cases? Alex and paul champion. P.s. Please excuse if my part numbers are wrong - I am checking them via google. P.s.s I am sure there will be more to follow. [/QUOTE]
