Re: Nylon Filter in the By-pass Valve Plunger

I decided to go for it - just this once! All has gone well so far, but I just can't get the nylon filter out of the bottom of the plunger. Is it screwed in? Is it made from plastic?

Thanks.

Gear Lever Rubber Boots

Is it simply a matter of removing the gear knob on an 880 Selectamatic, and sliding the boot on, or does the boot have to be ‘fitted’?

Thanks.

Re: Radiator mounts

Do they look like this? I just removed the radiator on my 1948 Cropmaster and found what seem to be rubber sleeves in the chassis bolt holes. I can't seem to get replacements.

Re: Nylon Filter in the By-pass Valve Plunger

Has the filter always been there, from the earliest Selectamatics, but wasn’t mentioned until later manuals? I’m only asking because I have a 1966 770 on a ‘D’ plate. There’s no mention of such a filter in the manual, but does that mean the filter isn’t there? The 880 I’m servicing has been idle for...

Re: Nylon Filter in the By-pass Valve Plunger

Excellent - thanks for that. I didn’t really want to go there if I didn’t need to.

Re: Nylon Filter in the By-pass Valve Plunger

Hello, and thanks for your reply.

There doesn’t appear to be a problem. I’m just giving the tractor a good service as per the manual and so I thought I’d check that the nylon filter is clear, as I’m changing the oil and transmission/hydraulic filter anyway.

Thank-you.

Nylon Filter in the By-pass Valve Plunger

At what point did the nylon filter in the by-pass valve plunger begin to be fitted in the Selectamatic range? I have a 1967 880 and am reluctant to remove the dump valve and get into the valve chest if I don't need to.

Thank-you.

Re: 880 Selectamatic Idling Speed

Thanks for that. I did as advised and all is working now, although I did notice that a spring is missing.

Re: 880 Selectamatic Idling Speed

Where's the return spring located? Everything seems to be ok at the injector pump. The problem seems to be the cable at the driver's end, where it enters the sleeve (see pic below). The kink in the cable stops the whole cable from returning to idling speed.

Testing Oil Pressure Switch

Is there a way of testing an electrical oil pressure switch? I thought I’d ask this before purchasing a new one.

Thank-you.

Re: Drain 770 Tank

My 880 Selectamatic has the fuel pipe leaving the bottom of the tank to a shut-off valve before making its way to the sediment bowl. Problem solved with the 770. I just disconnected the pipe at the sediment bowl and the diesel flowed out. I thought it was going to be a bigger job than envisaged. Tha...

Re: Drain 770 Tank

I could be wrong but the fuel delivery system to the sediment bowl on the 770 is different to that of the 880. There doesn't appear to be a shut-off valve, and the pipe leaving the tank for the engine isn't at the bottom of the tank as per the 880, but is at the top.

Drain 770 Tank

What’s the easiest way to drain a 770 fuel tank, bearing in mind the outlet is at the top?

Thank-you.
