Hi
I am having to replace the blade in our thetford c400 cassette toilet. I have opened the toilet cassette, ie. blade mechanism, and replaced the blade but, now cannot get the blade mechanism to lock back into place in the cassette unit. I have lined up the arrow with the circles/ dot, but cannot get it to rotate into place. i dont want to use excessive force, and break it further. I have tried washing up liquid, olive oil, and light motor oil to lubricate the mechanism and large seal, but it seems the rubber seal is stopping it locating in the cassette. it works perfectly well without the seal.
Does it need a great deal of downward pressure, whilst rotating it into place.
anyone got any ideas on how to get the blade locking machism back into the cassette?
very much appreciated.

Hi all sorted it now.
Take a piece of hardboard and cut to same size a flat/slide on toilet mechanism. attached a piece of 2 x 2 inch wood about 3ft-4ft in length.
Slide the hardboard over the toilet mechanism where the slide lid goes, alighn the arrow and dots, palce a littel pressure ontop and rotate into place. return to toilet cavity in caravan.
hope htis helps anyone else

You've jogged a memory there, actually on two points!
Seem to recall (don't remember where, may have been on here, may have been elsewhere!), that someone did something similar, but broke the channel the sliding cover runs in as applied too much force, so obviously care needed.
I'd forgotten, but I had removed the blade mechanism on my tank a couple of years or so ago, to sort a sticking float. Seem to recall even with the old (previously compressed) large seal, and plenty of Thetford blade seal lubricant, it was still a tough job to rotate the assembly back into place. I would imagine if a new thicker/springier seal, it'd be harder still!
Glad you sorted it.
I was very lucky a few years back, I spotted a new tank for sale at a bargain £15 IIRC, so snapped it up PDQ! So have peace of mind that I can swap tanks, fix old tank problems at my leisure, and if I do break it, still have a fully functional loo!

that was my issue with just using the blade on top of the tank,chance of snapping the guides, hence a piece of similar shaped hardboard and fully slipped in to channels, to reduce the chance of breakage.
