Neighbor brought a 1370 here that was missing so by crackink injectors determined 2 middle cylinders were missing-both on 1 head. Than pulled injectors an tested both.Shop that tested said they were ok- sprayed at 2900psi.Than put air pressure in injector an air came out breather faster than it should.Turned crank to proper valve position on other piston an put air pressure in that cylinder an air also came out breather faster than it should- both cylinders ! not having enough compression to fire. tHAN PULLED HEAD AN REMOVED PISTONS AN BOTH HAD 1 BROKEN COMPRESSION RING. Proud of self as i found problem !!! Cleaned an cleaned-checked for cracked pistons an head with magnafing glass-found none- squirted fuel in on top of valves -no leaks-put back together an started today an it still misses on 2 same cylinders. Inj pump seems to put out pressure but there is no indication of unburned fuel when idlingsuch as white puffs. Need some opinions

Unhook #3&4 inj. lines from inj. pump and pump fuelprimer. If ANY fuel comes out of inj. pump fittings, copper delivery valve gskt is blown. These gskts, if blown, will cause a miss at lower eng. speeds.

I have what sounds like a similar problem in a 1210 David Brown. Do you mean cracking lines at injection pump and fuel lift pump? How can it not leak fuel when you do this? I am green at this please explain.

Cheers

Mitch

We are taking inj line off pump completely and pressurizing charge side fuel system with the lift pump primer. Won"t work on rotary pumps, perhaps on inline Simms used on some DB tractors. I don"t know. Were looking for a leaking delivery valve.

Shut off fuel,remove delivery valve holder(inj. pump fitting) spring and little plunger dingy. Fish out old copper gskt. I hold "guts" in pump down with a pick and blow gasket\pieces out with compressed air.Set new CORRECT copper washer on top of plunger and CAREFULLY put fitting, spring and dingy back on pump and tighten LIGHTLY, not real tight, just snug. Good idea to remove rectangular cover and check that rack moves freely before starting, or have a pair of cutters ready to cut fuel hose in case of eng runaway. You should start having solid bowel movements again about a week after fixing tractor.

Thanks to you an also to Grumpy for his response couple posts back. To late to doas you said tonight but i bought a Bosh book on e bay an have looked with magnifing glass at illustration in book an i think i see gasket you mention. Do you think that could just be loose enough in housing to leek? If so looks to be ok to tighten it? My 830 has clamps holding 2 together so they dont turn -have always been careful not to turn them when working on tractor but things happen.
