Beisan Vanos diy'ers: splined shaft cover giving me trouble

[bavarian3]

For those that have done the Beisan rattle kit, was any trouble had removing the splined shaft covers? These things are laughing at my Makita xdt14z. I've tried applying heat with a heat gun and still no luck. Wondering how hard I can go with heat or if I should bring it to someone with an air impact.

Thoughts? Thanks in advance.

Beisan says something about shocking it with the impact wrench to break it loose; otherwise, the impact is not strong enough.

I have taken apart two sets of splined shafts with no issues. Just use the special socket with a good long breaker bar.

Do not heat the splined shaft with a flame. The bearing inside has a plastic retainer that will melt burn/melt under extreme heat of a flame.

Yeah you're gonna need an impact wrench. My XWT15 1/2” drive got it done.

[Shonky]

I did it with a fairly average Ryobi impact but yeah I think the impact did it fairly easily from memory.

I would not heat them at all as there are thrust bearings with plastic carriers inside.

Thanks everyone. I managed to get them off.

The Makita XDT14 is an impact. Perhaps not strong enough.

I ended up applying heat with a heat gun, shocking several times with the impact, then finally breaking em' loose with a breaker bar. Not sure why mine were so tough but the breaker bar alone/initially wouldn't do it. It's also against Beisan instructions to use a breaker bar/ratchet to do the initial loosening.

FWIW I double-checked the bearings as I haven't sealed back up the covers yet, and they are perfectly fine. No warpage or odd effects.

I also sent this original question to Beisan and received this response which is on point with the advice here.

"He needs a stronger impact wrench.
He could apply heat, if it was too much heat, he probably needs new bearings.
He should not use a normal wrench with a long handle, then he skips and breaks the small thread."

Hope this helps future readers.

Isn't the XDT14 an impact driver? Because that is not the same as an impact wrench.
Drivers usually have less torque than a wrench to start, plus the socket adapter further reduces torque and impact shock.

Ahh, you're right. Thanks for clearing that up. Live and learn.

It's also worth noting after my back n forth with Beisan, it was recommended to purchase new bearings. I purchased em' for peace of mind incase they were made brittle in any way. They are relatively inexpensive it'll just keep the car down another couple days. https://beisansystems.com/product/2-...4-euro-s50b32/

If you're serious enough to do your own vanos work, you should really consider investing in a proper impact wrench.
Since you like Team Teal, the XWT17Z is a solid buy.

Not sure why mine were so tough .

I think the cover was thread-locked to prevent it from backing out as the shaft rotating CW.
Did you find the thing with axial plays and in need of rebuild to prevent rattling? If not then I would never touch it.

already looking at options to add my arsenal =)

this and the s62 spring plates seem like unnecessary money spent, but too late for that. plus a forum guru said it's needed so it MUST be true

Doing anti rattling is not a trivial task-people ended up with more problem than before.
