B7100 Help... hydraulic screens

[Kenonf]

I did a Hydraulic oil change, and for the first time i tried to clean the screens. I was able to remove the pump side but I was unable to remove the HST side. I tried some penetrating oil and tapped on it with a hammer, but no luck. I am very concerned about shearing off this bolt. Any suggestions. The screen on the pump side was clean, very clean for about 3000 hrs of use. Thank you

Longer handle on the wrench may work but there is always the danger of breaking something. Impact wrench may be worth a try.

I have pretty much gone to using an impact gun to get the screens out, much faster and easier.

PS. Make sure you are using a 26mm socket.

Righty-tighty, lefty-loosey?

X2 on the impact. Although if you don't have one...I hesitate to even recommend this, because if you're not careful it can lead to a rounded-off bolt head, or worse... but...

A "poor man's" impact wrench is putting your wrench on the bolt, and while applying some leverage with one hand, tap/pound the end of the wrench with a hammer using your other hand. The combination of leverage (torque) and hammer (impact) works much better than either one by itself.

Just don't get too carried away and smash your wrench hand with the hammer.

There are proper Hammer Wrenches out there.

except maybe 6 point? But i never saw anything like it, I go with the red/blue hot wrench when in need.

They will come in six point too. Maybe not so common anymore but there are places they are used.

I read a note somewhere that 12 point socket/wrenches are what lead to rounded off bolt heads? That you are better off only using 6 point.

Not having one doesn't really help in a pinch though, when you're laying under the tractor with your drain pan all ready and nowhere to go... now does it.

Rather strange that the one in your picture is 12-pt., unless it's for a 12-pt fastener head, or for somewhere where access is pretty limited.

I strongly dislike 12-pt sockets/wrenches... I don't use them unless there's no other option. There's a reason standard impact sockets are 6-pt.
Newer styles that grip on the flats instead of the corners are the way to go. :thumbsup:

OK Trivia Time: I've got one of these somewhere in my "special tools" chest. What is it for, and how do you use it?

That is why the only 12-point sockets I have in my toolbox are for special applications all of the rest are 6-point. My engine building box has 12-points in it since a lot of ARP fasteners are 12-point.

The proper tool is not always readily available when needed is it?:thumbsup:

Nothing strange about the picture. It was the first one I found.:thumbsup:

Trivia time-VW rear axle nuts,came in 36mm and 46mm(bus),apply torque with breaker bar and hit flat on tool with hammer to loosen.Cool!

Perfect answer! :drink:
Yep, pounding on the ears of the tool produces the same torque multiplier effect I described earlier. I've seen some impact wrenches that are useless against these axle nuts, but this tool usually busts them looses in no time. :thumbsup:

:thumbsup: on the ARP. I don't think I've ever purposely bought a 12-pt... the only ones I have came in a larger set. Quite a few have never been used. :laughing:

Doesn't it always seem that way? Or, maybe you do have it, but it requires a several-hundred-yard uphill trek back to the garage to find it? The only time I ever seem to jam my chainsaw and need the bar wrench, is when I forgot to bring it with me. :laughing:
