1 Technical Question on the Thetford Blade 50731 for Thetford C-400 Series/C260 +C200 Holding Tank


We have a C-402X thetford cassette toilet. When you go to use the toilet you push a knob which normally opens the toilet up. At the moment we can see the blades moving and the black 'disc' which would appear to have come unattached to the blades is sticking . Can you please advise what part we would require. Thank you


The easiest repair is to replace the mechanism, our part 137137 for a left hand version or 137138 for the right hand. The mechanism can be removed by turning the whole assembly anticlockwise and lifting it away from the holding tank. The black disc is known as the blade and is our part 137139 and if this is the only part broken then you may feel that you just wish to replace this part.

Arrived in time stated and happy with service we received from this company. The item was as expected as a replacement part for our toilet which is 10 years old. Easy to fit after finding a useful video on YouTube.

Had to change the blade, not a difficult job to replace, but the item is known to break. Thetford should strengthen the stud.

the instructions to insert this item will make more sense when the blade assembly has been removed from the tank. follow the steps and you will get there. the centre post on mine had worn down and i was pleased to note that it had been modified and is more robust.

I'm really impressed, ordered this on Monday morning and it arrived on Wednesday! Like what others have said, the spigot had broken on the original part. This new one appears to be a stronger design. Supplied instructions (Thetford own instructions) are clear and this is a simple job to do.

'This Thetford blade replacement fitted easily and perfectly, with clear instructions on how to replace it. The delivery was next day. Unfortunately as with all items for motorhomes they are very overpriced. I am sure the manufacturers think we are cash cows!

Fitted with ease, saved me £32, when you realise you don't have to buy the full centre of the holding tank, this will be the first shop I will visit in the future. Great place to view, many thanks

Ordered the parts to be shipped to the United States. Parts came in about 2 to 3 weeks. No problem with the long shipping as this company had to order the parts from the manufacture and then ship them over seas. Very happy with the customer support!

The blade had sheared off so presented with a mucky job. Thanks to Leisureshop Direct I found the replacement part with instructions so ordered. They did not advise that the item had been dispatch so I emailed but at the same time item was delivered. So a good dispatch service despite that issue. Was able to give cassette a good clean - warm vinegar removed scale along with a good hose down. Item fitted very easily so lubricated all seals with olive oil. Now have a sparkling cassette which is too good to use. Many thanks Leisureshop Direct.

Replacement Blade On Thetford Toilet

by (11 May 2013)
5 star review(5/5)
This obviously replaced a broken blade from my existing toilet. The new blade has a more substantial build and shouldn't break shouldn't have broken in the first place, but that's another story. Comes with comprehensive fitting instructions, so no need to google Thetford again! And finally, it was sent very quickly by Leisuredirect, so definitely no complaints there.

Thetford Holding Tank Blade For C400 Toilet

by (16 Oct 2012)
5 star review(5/5)
This part was bought to replace the original: the peg broke off the disc. Finding the part needed was easy, from an exploded diagram. Being able to buy only the broken part avoided pointless expense. The order arrived in three days. Repair instructions were included. The repair took about 10 minutes. I wish more things were so easy. The part supplied is slightly different fro the original, and probably stronger. 5-star rating for part and service!

The product was delivered quickly and fitted easily with excellent instructions. The price was good but a pity that delivery cost more than the part. It turned out that my local dealer had one in stock for 4.99 so I bought one as a spare.

We received the new blade the day after we ordered it..........great service and we'll certainly be back for more. The blade itself seems to have had a design improvement and should be much stronger and last longer. We thought we were going to have to buy a whole new mechanism, so were very pleased that this cheap remedy was available.

Great service,item arrived within 3 working days.Fitted it no problems. An improved design, but i suspect it may break again ( in a few years ) due to the pressure on the end of the spindle. Works great toilet now working as new. For around £6 delivered I might hold one in stock !!
