Graham Posted July 19, 2017 Report Share Posted July 19, 2017 Roy thats correct, if you want the followers out head has to come off I believe. Quote Link to post Share on other sites

RogerH Posted July 19, 2017 Report Share Posted July 19, 2017 Hi Roy, the top of the block is the only place they can come out from. What is stopping them from coming out. Roger Quote Link to post Share on other sites
john.r.davies Posted July 19, 2017 Report Share Posted July 19, 2017 (edited) With head off two methods, viz 1/ stick finger down follower,crook, pull & twist until it comes out. If you ever have, think finger jam as in rock climbing. 2) a Rawlbolt from your local DiY. Insert and expand, then as before. Easier on the knuckles!

Andy Moltu Posted July 20, 2017 Report Share Posted July 20, 2017 Can sometimes be tricky to get out because there may be a ring of "gum" around the top of the travel of the cam follower in the block and or the bottom of the follower has mushroomed slightly if it is knacked. Has to come out upwards with the head off. You are unlikely to be able to get the cam out to drift it from below with a wooden dowel. Quote Link to post Share on other sites
roy53 Posted July 20, 2017 Author Report Share Posted July 20, 2017 It dose seem to be catching on the bottom as it gets to within 2mm of the top then stops. Have tried a follower from next cyl and it goes in the top ok. Everything is working fine just checking whilst the head is off. Is mushrooming likely ? Roy Roger annoying Sue sounds like a not good idea Quote Link to post Share on other sites
TriumphV8 Posted July 20, 2017 Report Share Posted July 20, 2017 If cam is worn it might affect the bottom of the lifter. Carefully look and try before you spoil the block when forcing the lifter out to the top. If cam is okay its more likely that there is some mud at the bottom. Quote Link to post Share on other sites
Fireman049 Posted July 20, 2017 Report Share Posted July 20, 2017 Hi Suzanne ~ I see you're ready for take off!! Tom. Quote Link to post Share on other sites
dingle Posted July 21, 2017 Report Share Posted July 21, 2017 Has anyone considered enlarging the opening in the head enough to remove the lifters? It wouldn't take much-maybe .100"+. Might be something to ponder the next time the head is off. Berry Quote Link to post Share on other sites
roy53 Posted August 18, 2017 Author Report Share Posted August 18, 2017 AN update the engine has ended up being removed and the cam taken out. No 1 follower which was the sticking one has flared at the bottom and also concaved. As it was no 1 i managed to extract it from the front of the block by pushing it down.All other followers are fine and high motorsport spec so concerned as to why 1 failed. concaved and flared at the bottom almost serrated bur if you get what i mean. need to now check spec of first cam lobe . strange that it still ran ok and was revving up to 7000 Roy Quote Link to post Share on other sites
Nick Jones Posted August 18, 2017 Report Share Posted August 18, 2017 (edited) Having dismantled quite a few of these engines over the years (and also the small 4 pots) I've found that the front and rear follower/cam lobes are almost always the worst worn/damaged. My hypothesis is that they get less well lubricated than the others though I have no hard evidence for this and it's not really clear why this should be. How many miles had the engine done? Worth checking the valve spring(s) that relates to it in case it's stiffer (excessive pressures) or softer (valve bounce) than the rest. As it was still running well you might find that the cam lobe is still largely intact, though it must have suffered to some extent.
