Re: 990 selectamatic height control

If you look at the parts diagram link posted above, youll see 2 friction washers that rub either side of the bottom of the quadrant. You can see these without dismantling anything. Unless they are missing or extremely worn you should be able to tighten the nut to put enough pressure on the washers s...

Re: 990 selectamatic height control

When you tighten the friction disc, only do it just tight enough to hold the quadrant lever in place. Where the C section lever connects to the pivot block is a weak spot and if the friction washer is overtightened this joint will flex when you move the lever and eventually break off!

Re: Dash lights.

Its all 3 dash lights that stay illuminated when running so likely to be a wiring fault rather than 3 separate faults on oil/vac switches/alternator............ unless the tractors got some serious problems!!!!!!

A later development is the alternator, and it produses alternating current and this generator type do not need a regulator. The parts inside the AC generator is a rectifier, produsng direct current using 3 diods.
Theres also a regulator inside an alternator

Re: Dash lights.

If its all 3 lights then its almost certainly a wiring fault. Have a look at a later wiring diagram for 880s with the full flow filter as thats the diagram for tractors with the 3 separate lights. With the ignition switch on you should have 12 volts on one side of each of the lights. The simplest ci...

Re: Dash lights.

Are you saying all the lights are staying on or just the oil warning light, as thats the only one you mention? If its all the lights its probable that theres an error in the wiring. If its just the oil warning then its not unknown for a new switch to be faulty. First thing to do is be sure youve act...

Re: Door latch on Sekura cab

Given that what was probably originally a rectangular hole is now clearly rounded, anything other than brazing/welding is likely to carry on moving, wear some more, then fail again. So long as theres no rubber/plastic that will be affected by heat Id have thought it should be straight forward to bra...

Re: Gresen loader valve seals

Turns out the original seals are a square section with a thin lip for sealing. My spools had a tiny bit of pitting/corrosion where the seals rub so dressed that smooth with some emery. The seals at the spring end werent leaking so Ive left those in place. The leaking seals have been replaced with 25...

Re: 996 project tractor

Plenty of parts manuals here including one covering the 996 https://sites.google.com/site/deerebrow ... ts-manuals

Maybe not as comprehensive as the online version, but a useful backup especially if theres a copy on your hardrive and the internet's gone AWOL

Re: Gresen loader valve seals

Im sure I could find imperial sizes if I looked a bit harder but recent experience with fitting the correct 3/4" o ring to a leaking lift latch that continued to leak with the "correct" o ring fitted, has made me aim for a tighter fit if possible. Maybe there was a sliver of wear or corrosion that m...

Re: Gresen loader valve seals

Thanks for offering to find out but Ive measured up the spools and theyre 1" so it must be 1 1/4" OD with 1/8" thickness. Ive ordered a couple of choices of metric equivalents so hopefully theyll be a good fit.

Re: Gresen loader valve seals

once you have it stripped go to any local tractor agricultural dealer. show them the o rings dont confuse them with what there for etc they will bring out boxes of assorted ones for literally pence Was hoping to have the correct O rings to hand when I stripped the spools but with no reply from Park...
