Jacked 8 Posted January 6, 2015 Looking at replacing my lifters in the clevo, found this video: Is it that easy? Anything he is missing? I know I have to soak them overnight in oil. Cheers. Share this post Link to post Share on other sites
Trevor 326 Posted January 6, 2015 Is it a standard Clevo with standard heads? If it is you don't need to do anything, just pull out the old lifters and put the new ones in, there is generally no need to adjust rockers on a standard engine, the whole point of hydraulic lifters is to take away the need to adjust rockers, but I am not a mechanic. There is a really cool tool you can get for pulling out the old lifters, not sure if you can get them in Aus, I am sure you can somewhere Share this post Link to post Share on other sites
xwagon 168 Posted January 6, 2015 does your engine have roller rockers? Share this post Link to post Share on other sites
Jacked 8 Posted January 6, 2015 Yeah, edelbrock heads, roller rockers, poly locks and girdle, same like video. Share this post Link to post Share on other sites
gerg 10,871 Posted January 6, 2015 As Trevor says, no adjustment needed after initial setting. If your old lifters are mushroomed, you may be in a world of poo. In this case, don't try and lever them up though their bores. You'll badly score them and lose oil pressure from then on. You'll need to hold each lifter up with clothes pegs, yank the cam out and push each lifter down into the cam tunnel. I made up a nifty tool to collect them: cut a 40mm PVC pipe in half down the middle, shove it down into the cam tunnel and push each lifter out one by one into it. Carefully remove individually so you don't drop any of them into the guts of the motor. 3 Thom, scottly and Crazy2287 reacted to this Share this post Link to post Share on other sites

PRO250 1,506 Posted January 6, 2015 When I switched to alloys I have to run a 7/16th stud roller I set them up once and forgot about them its 12.000km in now and still finejust set and forget if it has a chatter look close as there may be a issue Share this post Link to post Share on other sites
bear351c 10,270 Posted January 7, 2015 I always put mine in a cup of oil, (one at a time) and push up and down on it with an old pushrod. Whack 'em in, and Robert's ya Farvers bruvver. 2 gerg and Thom reacted to this Share this post Link to post Share on other sites

Trevor 326 Posted January 7, 2015 We always soak them in oil first, all the good mechanics recommend that Share this post Link to post Share on other sites
Jacked 8 Posted January 7, 2015 Wow, a lot of input thanks guys. So just to clear up, there was no mushrooming on lifter. It slid out perfectly fine as there was still heaps of oil everywhere. I'm just tossing up between replacing the one lifter that's damaged myself, or taking it to a new engine guy that a mate has dealt with building his car with. If it's as easy as the video, I can do it at home. It will be easier running in one lifter rather than a whole new set of them. Going to speak to new engine guy soon.

Jacked 8 Posted January 7, 2015 As you can see, plunger got stuck down and then got bludgeoned by the molly pushrods. Share this post Link to post Share on other sites
Thom 6,650 Posted January 7, 2015 Re use the lifter body ane replace the guts with those of a new lifter the you can stick it back in and not worry about re-running in the lifters 4 bear351c, gerg, PRO250 and 1 other reacted to this Share this post Link to post Share on other sites

gerg 10,871 Posted January 7, 2015 Need to find the exact same brand of lifter but good idea 1 bear351c reacted to this Share this post Link to post Share on other sites
Crazy2287 1,886 Posted January 8, 2015 In the video he is setting preload by pitch of the thread. If you know the thread pitch is, for example, m10x1.25, then you know 1 full turn is 1.25mm, which will give you your preload. remember the fulcrum when setting preload this way is the valve stem and the effort is the rocker nut. The amount of preload will be affected by the rocker ratio. If the ratio is 1:1 and you move the point of effort (the rocker nut) downward 1mm then the load (preload in this case) will move down 2mm.If you want to set up preload properly, install the rocker to zero lash like in the video, then stop. Get a metal rule and place it across the top of the head, where the rocker cover gasket usually sits, so that it sits against the pushrods. Get a paint pen/white texter and mark roughly this position with a fat line. Then use the rule again, at zero lash and mark a line on the pushrod with a sharp scribe. Then tighten the rocker down. Again use the rule to mark a second line on the pushrod. The distance between these 2 lines is your preload. Typical preload is .020-.060" or 0.5-1.5mm 3 bear351c, Thom and Clevo120Y reacted to this Share this post Link to post Share on other sites

Jacked 8 Posted January 13, 2015 Thanks for the info guys. Went to a performance shop in The area and the guys there quoted me around $800 to install whole new set of lifters, and to run them in. Think I'm going to go ahead and just replace the guts of one as stated above and see how it goes. If all goes pear shaped I'll look at going rollerised but that will mean car off the road for a while as I don't have the funds. Share this post Link to post Share on other sites
gerg 10,871 Posted January 13, 2015 Wow they really mustn't want your business if they're charging that much. I'd expect a cam thrown in with that as well, with a couple of oil filters and 2 lots of oil (one for break-in). That's just robbery. Share this post Link to post Share on other sites
