Crown MKII hammer adjustment

[Chukar60]

Picked up a new Crown MKII 25 today and played a bit with it. Now I am ready to do some tuning.
I started raising the reg pressure and ran out of hammer @ 135 bar. I could not get the NSA 26 gr slugs past 810 fps.
Now I want to adjust the hammer tension that interacts with the power wheel .
Before I even got started I watched a couple videos and got conflicting info. One said counter clockwise increased tension and the other said clockwise did.
Which is it?
I have seen posts here that indicate I should be able to get those slugs into the low to mid 900 fps range without any modifications.

clockwise raises the tension pre load turn it in more hammer

Thanks Douger!! I hated to even ask that question. Intuition told me clockwise but I got myself a lot of extra work diving into my other guns without asking questions.

So now I need to find out what I can get out of those NSA slugs then maybe go up in weight. I was unimpressed at he low speeds.

Be careful when running the hammer up high on the crown power wheel. When you have the power wheel set to the “max” setting it likes to chip the end off the cam on the aluminum wheel. I would recommend not using the “max” setting.

Thank you for the Advice

Thanks guys. Took the Crown out after making some initial adjustment to the hammer spring tension. Had to go a bit further than I anticipated with the tension but I was able to get the NSA 26.8’s to 970 fps On PW setting 20. Mrshosted, I took your advice after looking at the cam. Running on position 23 looked dicey.
Backed the wheel down to 13 and it was shooting FX 25.39 pellets @ 885.
could only get to 30 yards but the pellets were literally same hole and the slugs just very slightly larger than that. Good starting point. Hopefully this weekend I can stretch it out and see where I am. Think I am going to like this Crown a lot.

You need to reach out to @Mrshosted for his upgraded power wheel. The factory one gets chewed up fast and you will see inconsistencies from the chewed up power wheel. Worth every penny.

Thanks. I saw pictures of them and assumed from the marked positions they were for the MKI. I will reach out and get the details from him.

I’m just finishing a small batch of power wheels now, your welcome to pm.
