Re: 1965 David Brown 880UE Implematic, how to prime transmission hydraulic pump?

Earlier in the thread before you swapped the pump gears, you got a good flow out of the pump driven by a drill. Although thats no guarantee of a good pressure it might be worth trying that test again to see if you get a good flow with the gears in the correct place. If you do then no flow out of the...

Re: flushing out transmission/Hydraulics

Thanks all. There's a loader on the tractor also. So i'll have to drain the rams. Looking through some of the forum for "flushing" it is best to disconnect the return hose from the loader and operate it up/down to flush out also hence using hydraulics but the advice is to operate it just enough to ...

Re: selectamatic wiring

Hi yeah when I Google it it comes up with the four connectors , but it's definitely that number on the back of the switch and doesn't look like anything broken off , as I said there doesn't seem to be a double three connector in any of the wiring diagrams in the repair manual Seems the 128SA is the...

Re: selectamatic wiring

A lucas 128SA seems to be a 4 position switch with 3 double connectors and 1 single connector. If its a 128sa thats being used, maybe the single connector has been broken off?

Re: selectamatic wiring

Are you sure you have the right switch? Youll need connections for the following 4 circuits-
12v supply to the switch
12v out to the indicator lights and any guages fitted
12v out to the thermostart/manifold heater
12v out to the starter

Thats 4 separate connections youll need

Re: Case 990 selectamatic

I think that most ressonable quality multimeters will messure DC amps so maybe easiest to put a multimeter in series with the fuse(one after the other) and measure the actual current on the tractor.

Re: Voltage Regulator / Dynamo

However the description on a lot of them is a little lacking. Could you provide the exact name of the manual that has the chapter on electrics? Near the bottom of the list of manuals is one titled Tractor Service Manual 770-1412. Click on that and a load of different sections open up. Section W is ...

Re: Voltage Regulator / Dynamo

If you search the forum for "haynes manual" and follow the link, at the bottom of the list of manuals theres a selectamatic service manual that includes a 67 page chapter on electrics including dynamo operation, fault finding, adjustment and repair

Re: DB 990A Implematic Hydraulics Not Working

I dont know the specifics of an implematic but if its anything like a selectamatic there will be slugs of contaminated oil throughout the hydraulic system. If you put fresh oil in it will get contaminated. Usual advice for a selectamatic is to flush by refilling the gearbox with diesel, driving gent...

Re: 880A Selectamatic information request

Back to the 880.... the conduits are routed as shown in the pictures earlier in the thread. From the end of the conduits the cables run inside the mudguard through one of the roundish channels formed in the mudguard to give it ridgidity. If you look on top of the mudguard just inboard of where the l...

Re: 1967 DB 880 Dashboard

Unfortunately the parts catalogue isnt of much help in working out where the blocked filter lamp went between serial number 543157 when the filter and lamp were introduced and serial 544392 when the dash was updated to include the lamp. Theres a technical note and an addendum to the user manual that...

Re: 1967 DB 880 Dashboard

From the info I have- The paper suction filter was introduced from serial number 543157 around Aug 67, so a few months ahead of the dash update. Fuel gauge was an option from serial number 536080 My early 880 doesnt have any cutouts for indicator lights but has a blank cutout where a temperature gau...

Re: 1967 DB 880 Dashboard

Info Ive got shows the instrument panel was updated from serial number 544392 around november 1967. Does that serial number run just before yours?
