Thanks for that. Terry

Those units are known to strip the splined input shaft. Could that be part of the issue? I have a Sabre that happened to. Haven't had time to repair it yet.

Thanks. I have checked that. It appears the pump faces are the issue allowing oil to pass when it shouldn't. Consequently losing power. Rebuild needed I fear.

Way back in post 2 you got a plan
Pull it off remove the fill /drain cap carefully
Tip upside down for 24 hrs to drain most of the oil out
Refil with a heavier, thicker engine oil, even a cheap supermarket 25W 60 should give you a couple more seasons for £ 20
SO then you should have 3 years to decide what to do
Note the heavy oil is the proverbial banana skins in a noisy diff bodge that would do Arthur Daily proud but usually works for 2 to 5 years and the parts are already throw away condition

Thanks for that Bert. Take care, Terry

Hey Terry, I would pull 16oz out of it and pour a bottle of Lucas transmission stuff in there, that's about all you can do at this point. There is a guy on here somewhere that you can send the parts to and he rebuilds it and sends it back. He may be on ebay too, but it's a 100 bucks. It could be youtube I saw him on too. Here in Texas you can buy a complete mower for 200 bucks with a bad motor and yank the tranny

Thanks for that. Yes you are lucky to be in Texas, everything costs a fortune over here!

I decided to take the cover off the Tuff Torq K51 to check the filter. However after previously draining the the unit by removing the plug and turning upside down and letting it drain fully over 2 days. I then refilled it with Triax Trans Zero 20w 50. I purged it and ran it around the grass for about an hour. It was still hesitate, so decided to remove it, drain it and split the housing so I could check the filter. However the oil came out very cloudy, like it was emulsified. Which I fould strange as it had only had about an hours running. The oil I used can be seen in the foil cup in the images, totally different to that in the tray and in the filter, again in the pictures. I am going to replace the filter and refill, but worried the oil might do the same. I welcome advice on what could be the problem? Thanks, Terry

You need to use ENGINE OIL not transmission oil which has a high film strength so bubbles created will take a very long time to pop
I did mention what to use
