6718 magnetic filter

[Brian]

Hi
I started to get a leak yesterday around the magnetic filter(under the seat)
On closer inspection i found the bung would not tighten but would just become loose again every time it appeared to start to tighten, the threads on the aluminium bung look badly worn.
Any ideas where i would find a replacement? the proper name for this bung?
Also when i first got the 6718 the flow pipe to the remote was routed from under the seat and connected to the gearbox filler? (by the little dipstick, near the brake pedal) Any thoughts on this? I blanked the filler off and re-routed the pipe out the rear to my log splitter.
Yesterday was the first time i have used the PTO. I have had the log splitter on until now but needed to cut some grass, so switched it for a topper.

It is the same as the filter in the steering tank. It is called a nut part no 958018. It comes apart, that is the number for the nut only. Supply won't be a problem, look online. There will also be a Zetor parts supplier in your country.

Hi
Thanks for your reply.
I have found the part on a dealer site

http://barlowszetor.farmgear.co.uk/marketplace/advert/13477/

I am guessing now that as the thread has gone i will need to change the whole part as on the dealers site, not just the top(nut)
anyone know how to change the bowl part?

Ps. ive fixed this link now

Hi
The nut is screwed direct into the castirontopp of the rearaxel, i doubt you need to do anyting but clean the tread and filter/magnet and screw inn the new nut.

Hi Bjarne
Thanks for taking the time to answer my post.
Ive looked closely at my filter housing and it does indeed look like it is aluminium set into the cast iron casing. the threads inside the housing look in just as bad shape as the thread on the cover its self.
I am worried that if i purchase the cover only i may still not be able to draw the cover up tight enough.
While on the subject the Oring that seals the cover on my tractor is quite hard, is this normal? Or should it be like soft rubber (usual Oring type).

Regards Mambo

Ps. is it not possible to post photos on this forum?

Thanks Bjarne thats a great help .

Right got the parts and fitted them, but i dont want it to happen again

when i first got the tractor the feed pipe for the rear accessories was connected to the gearbox filler point, i have seen this done on other zetors.
i disconnected this to use a log splitter on the 3point linkage, then the first time i used the tractor without the log splitter connected (i had a mower on the back on the pto, but may have had the lever set so the acc hydr circuit was still live) this filter started to leak badly. At this time the hydraulic feed was just dissconnected and hanging out the rear window.
is there a pressure release or something not working? is this why the pipe was on the gearbox filler point?

Regards

 

[Brian]

Nobody got any thoughts on this?

 

[Brian]

Ok another question
would it be ok to connect the feed and return together rather than having this pipe on the gearbox filler?

 

[Renze]

using the return oil directly again for pressurising, heats it up.

 

[Brian]

Ok thanks Renze i'll leave it connected to the gearbox filler for now

Hi
I dont se the point of this, when the lever is in neutral both these pipes should be witout preasure.

[Brian]

which lever needs to be in neutral ? and where abouts is the neutral position?

all the markings have gone over the years, and this is the first tractor i have owned.
