25cc 4stroke trimmer help

I have the BC490 4stroke trimmer. I broke a cam tappet with a bent rod. The motor is fine. I am trying to locate a supplier of motor parts to replace these 2 pieces. The motor is available for $70-$80 + shipping all over the web, but actual internals seem to be under tight guard. Are their any ideas on how I can purchase internals for this motor?

    I don't recognize that model number. What brand? With the engine priced that low internal parts are likely not available.

    Go to cub cadets website and put in your model #, it shows 2 different year models for the BC490. There will then be an engine section to view.

    Thank you for responding on this.
     
    it's the BC490 #41AD490C912  25cc 4-stroke, 2015.
     
    The part I'm looking for is not on their page.
     
    Perhaps the actual engine manufacturer would help. On my 2 stroke Toro as an example, the engine is built by Mitsubishi.
     
    This motor is in great shape, what a waste to throw it away for a $5 piece of aluminum.

    Might try calling your nearby Cub Cadet to see if they have the parts available.

    I looked up your unit on Parts Tree, internal engine parts including valve train are not available individually. This is common for off shore products, distribution is simply too costly. The other issue is labor on warranty repairs, it is more cost effective to install a short block. I used to work for an MTD distributor, this is the reality. Another option is replace the trimmer and keep the old one for parts.

    Is there someone that can direct me to who the actual engine manufacturer is? I've now got approx 32 hr of search invested and I've made calls to both Cub Cadet and the parent company MTD in Ohio, customer service was eager to try but just unable to help or confirm who actually makes the motor.
     
    I know the do-it-yourself-market is much stronger in Europe or Austrailia (searching on .uk or .au, I sometimes use their pages to figure out how to find parts here, broader range of data), are there ideas that might make this search a bit quicker?
     
    Is this motor used in brands outside the MTD family of tools?
     
    Is this motor or a varient used in the R/C world?
     
    Is this motor or a varient used in powering bicycles, scooters, go-karts?
     
    These might be ways to get around the MTD parts system to get this part. I'm sure it's out there, I just haven't turned over enough rocks.
     
    The images are of the good cam follower, I need an identicle one. maybe I'll end up making one?
