    Default A question about Morel solid roller lifters

    I have a set of Morel presure feed solid roller lifters.
    When test fitting them in the lifter bores ,the lifters wont just drop in. I have to sqeeze the nose of the lifter at the roller to get hem started in and after they pass the roller point they drop down easily. Is this normal or somthing to be concerned about?
    After the lifter is in the bore the lifter moves up and down freely, until I pull the entire lifter out,then the same thing ,there is resistance at the nose or wheel.
    It is not a problem with just one lifter and one bore.I tried random lifters and random bores ,so the problem exists with all the lifters and all the bores.

    I can not seem to find out much info on the Morel lifters on the web except for the fact that every one says they are the best lifters on the market. Do they not have a web site? Any help or opinions will be greatly appreciated.Thank's....Hal

    Been there - seen that.
    It is somewhat common. Not super common, but it is seen on an fairly often basis. Usually a block that has run before with that lifter bore size, and was not machined again.
    And the way I do it is make sure I have the free movement a fair amount over full lift. If I have that, then they are good to run. (This is on a basic high performance/some racing engine.) If this is a big dog, (1000+ NA) then I take out the mic's and make sure I have everything perfect all the way around and get the exact clearance I am looking for. But if the thing travels up and down nicely just past the operating range, you are good to go.
    Morel does not have a website or anything that I know of. They are a manufacturing facility and make lifters under many other names. I have not seen much on the advertising side of their company. But put two sets in two different engines this week alone. I love em.

    Hey Wannabe, I did measure the lifters at max lobe lift, and they do have free travel a fair amount over the max lift.
    It's no where near a 1000hp deal,but it will be in the 600-700 hp range ...Hal

    Morel runs about .0005" larger on diameter then any other lifter company.

    Hal, I'd be concerned.
    Having to squeeze 'the nose' to drop them in is not a everyday occurence for roller lifters. The fact that they are wider OD then the body raises concern and then add to the fact you can squeeze them down to lessen the OD enough for them to fit is even more so.

    A lifter sticking in the bore while engine running is a recipe for disaster.

    There have been a number of reported and documented failures (edit in and nothing erased in following hypens)-I've seen, 2 documented and thus known by Morel - the other reported/documented by individuals - with these same lifters. And, yes, in the same exact scenario all involving spreading of the fork in the wheel/axle area and not the body OD. Again, this is not having to to with the OD body tolerance/clearance.Unfortunately, one set of which was being run in an Australian competition race boat and led to engine failure. This same lifter set was sent back over here to the states and is presently being sent to a metallurgic lab for in depth analysis.

    I had talked to another cam company about their lifters doing the same thing. Turned out the fork section had micro cracks in the fork to body junction. The conclusion was that axle to body fit was not right and causing the fork to spread during assembly. Send them back. Turn around should be about a week. My lifter company was overly helpful.

    Thank you for your info Machinehead. Sounds like the same exact area. We'll see.

    Also great to here how it was handled for you. Are you direct with that company ?

    That's it Chris? That's the only reason why holorinhal's lifters are binding?

    What did you tell Hal ?

    Hopefully you atleast got him in touch with someone over at the factory that can help him investigate his issue further.

    I know of three bum sets. Machinehead will be 4 if same company, and there is another under the knife so the juries out on that. So, this thread may even be the same - so am I wrong to bring this up so that it may help him and avoid a catastrophe ?

    Machinehead's experience seems to be the easiest/best. Why ? He was taken care of right away. Sent parts back, they where investigated, the findings where thruthfully told to him, and he got another set.

    I don't think the manufacture is as big of a problem as you set them out to be. I think the source is causing some issues with incorrect advice and such.


    BTW: Chris, Why are you so pissed that I'm pointing this out. None of it is made up.

    Jeesh dude - you know I try to help out as many people as I can thru info and such. I collect data each and every day. I have more if you want me to spill it, and believe it or not, a lot of it is extracted from my own data collection and investigation.

    Dam - I even went down for the count swinging in your defense for a bout a year.

    Bringing up info in public isn't a bad thing. Sweeping under the rug is.

    Lastly, I'm no puppet and I take offense to that. Big offense.

    Just in case I get badgered for this, I edited the above at 12:20PM 7/30/08.
    If that shows on the above post, I haven't gone in and changed it after the fact.

    One needs to know what one is talking about, before one can answer a question
