Cropmaster Fuel Issue

I have a 1948 Cropmaster petrol/tvo. Last summer I changed the cork seal in the changeover tap due to a leak. Since then, whenever the tractor starts to pull uphill the engine stops. The tractor will then start again quite easily on the handle and will progress again up the hill for a few yards unti...

Re: Three-way Selector Valve Leak

Solved! The o-ring was on the plunger.

Thank for your replies.

Re: Three-way Selector Valve Leak

The plot thickens - I've now dismantled three spindles and have found no o-rings in any of them. So the mystery of how to stop the original leak remains. I think I'm missing something here...

Re: Three-way Selector Valve Leak

Thanks for the replies. Where should that particular o-ring fit? I've removed the screwed bush and then the mills pin followed by the spindle, but there's no sign of the original o-ring, and I can't see where the new one should go.

Thanks.

Re: Final Driveshaft Grease Nipple

Solved! On drilling out the alloy filler I could see that the grease nipple had snapped off sometime and the previous owner had left the broken piece in there and sealed the hole. I removed the broken piece, re-tapped, inserted a threaded insert followed by a new grease nipple.

Re: Final Driveshaft Grease Nipple

The grease nipple has been sealed. For reference, I've attached a photo of the other final driveshaft on this tractor.

Three-way Selector Valve Leak

I have an oil leak coming up the spindle when the valve's open, so I suspect the o-ring needs replacing, but will I have to drain the hydraulic oil before removing the spindle? I have a vision of the plunger flying out under pressure!

Thanks.

Final Driveshaft Grease Nipple

At some point in its history the grease nipple has been sealed shut. I'd like to put a grease nipple back there, but it doesn't look good. Do I have any options?

Thanks.

I used lint-free cloth to avoid fluff whilst cleaning the components.

Re: Nylon Filter in the By-pass Valve Plunger

Well, I did it. I didn't fancy it at all, but it bugged me that I was going to change the oil and main filter but not at least check the bypass filter (even though it was working). All has been reassembled and is working. The nylon filter was fine but I had to destroy it to remove it - it was stuck ...

Re: Gear Lever Rubber Boots

Well they’re on but they don’t stay fitted on the bottom, especially on the H/L lever. The original ones seemed to be fitted. Oh well...

Thanks for the replies!
