Push rod seals

[jddevel]

My first post and hopefully like other forums of which I am a member it will be a never ending source of great advice. So my first question. I`ve purchased a Benford dumper with a 3 cylinder Lister. My first problem is a serious leak from the centre pots push rod. So what is the best approach to repairing the situation please. I am reasonably mechanically minded. Thank you in anticipation.

The first thing you need to do is post as many pictures as you can of the engine, including serial plates and the leak.  That way the experts on this forum (I am not one of them) can determine the best way forward relevant to your particular model.

As suggested have attached couple of pictures of the engine.

Good on you for a speedy response.  The learned members will soon comment.  In the meantime, try get a few pics of the serial plate as this will help determine model and year

OK I`ve collected the necessary seals for the push rods and a manual. However apart from commenting that Hellerine rubber lubricant should be applied to the core of the seal on reassembly there is no information regarding their location,removal or replacement. obviously more may come to light when I start dismantling but ant advice will be more than welcome for a brief outline of the necessary steps required.

Once you have the cylinder heads off it will be obvious how to replace. As you say just lubricate with Hellerine. I did try to post the page from the parts book which shows the breakdown. But for some reason the site will not allow me to post an attachment.

Thank you. Had hoped/thought they were replaceable WITHOUT removing the cylinder head. Are you therefore saying that`s not possible? Is it because the bottom tube seal is not accessible without taking the cylinder head off ( I`m not at the engine at the moment so can`t visualize)?
