Hydraulic oil pump seal?

[Woodcrafter]

Hi all engine running nicley on the splitter now but now has a hydraulic oil leak from the pump coming out from the drive shaft. I've removed the pump and there's a rubber seal around the drive shaft but Its well attached and I didn't want to force/pick it out without some advice. Should I attempt this repair or take it to someone?

Thanks

The seal on the input shaft is often an "O" ring. replacing it required dismantling the entire pump.

 

Can you put some pictures up

I'm not sure that seal will be the problem, its probably just to keep dirt and dust out, not oil in.

 

I think the problem will be inside the pump.

 

Seals are available, I rebuilt a pump on my mog, the seal was £70 and fixed the problem (it had overheated and melted the plastic internals) a new pump was £450, so I was very pleased.

What machine is it on ?

Hi it's on a custom built log splitter it's been professionally made its run by a 6.5hp Honda engine I've found a replacement pump for £140 so hoping that it was going to be a cheap enough repair to not warrant the replacement.

I'll get some pics up this afternoon. thanks for replies.

It could be a shaft oil seal. Cheap to replace.

It will be an oil seal easy and cheap fix take seal out and either go to your local Erika and they will match it up but know how to charge or try sealforce.co.uk based in Dundee I think excellent service from them.

I had an oil seal go on a hydraulic log splitter, the manufacturer (Metabo) was of very little help. In the end, I contacted L&S Engineers with a photo + dimensions of the failed seal and they posted me some replacements which are now installed and working fine. I have always had very good service from L&S, highly recommended.

Some hydraulic pumps are easy to repair, and some will not.its pot luck. On my crushers, I have to take the engine out and disconnect the hydraulics, which is an hours job each way. Ifyour pump I easy to get at, try replacing the seal first. Its will cost pence rather than pounds
