brian falcone Posted May 30, 2022 Share Posted May 30, 2022 So cleaned carb. New points condenser cap rotor plugs and wires. It started on gas. Removed valve cover and 3 of the four valves that open to allow it to start on gas are stuck down. It's like there's no spring pushing them back up. The one on cylinder 1 moves freely with the lever that's moves with the handle. Any trick to freeing then up without removing the head? Also the cover on the front of the hydraulic pump is cracked. Not sure if it hit something or water was in there and it froze. So that will have to be addressed nexf. Quote Link to comment Share on other sites More sharing options...
TD5Jordan Posted May 30, 2022 Share Posted May 30, 2022 I have freed up stuck valves in the past by removing the rocker/lever assembly and soaking the valve stems in penetrating oil then lightly tapping them with a hammer to free them up . Once they are loose the springs should pull them closed . As far as your pump goes it could have been hit or frozen or possibly the hydraulic system relief valve is stuck closed or there could be another type of restriction causing the system to over pressurize and crack the pump ( more common that you would think ) good luck !

brian falcone Posted May 30, 2022 Author Share Posted May 30, 2022 These are the vavkes that open the compression chamber...they are just flat round pads when looking from the top Quote Link to comment Share on other sites More sharing options...
TD5Jordan Posted May 30, 2022 Share Posted May 30, 2022 You may want to have a closer look at your starting valves …..there might be more than round flat tabs Quote Link to comment Share on other sites More sharing options...
brian falcone Posted May 31, 2022 Author Share Posted May 31, 2022 I know. All I can see if them with the cover removed is the round top of them. 3 are pushed down flush with the casting of the head...the one for cylinder 1 is about 1/4 in above it. That moves up by I assume a spring under it. The other 3 are stuck down and I see no way to turn or grab them to try and free them. The machine was parked for at least 10 years with the lever pulled down for gas start Quote Link to comment Share on other sites More sharing options...
Rawleigh99 Posted May 31, 2022 Share Posted May 31, 2022 Can you pull the injectors and feed rope into the cylinder to fill it up? Then hand rotate the engine to put pressure on the bottom of the valve. Lots of atf or penetrating fluid? Quote Link to comment Share on other sites More sharing options...
mmi Posted June 1, 2022 Share Posted June 1, 2022 from first info, carbon and rust,the whole mechanism needs removed then it is soaking 2-3x day/weeks.Std baby valve under there. brass tools tapping and turning and special (low pressure) lever up thru plug hole.heat gun to...., < 250* consult NLA Mb Cat. lots of patience and waiting,as NLA valves for 50 yrs,then on to the std everyday issue of warped from rode hard.if it moves free but still is not closed. on to creating other issues,remove inj,install plugs ,fill to top with acetone/atf etc let set 2 weeks, add kats block heater and cook 2-3 days,begin as above. simply spend $500 remove head and go up $500 for each step from there. O you just wanted to see if it runs first Quote Link to comment Share on other sites More sharing options...
brian falcone Posted June 1, 2022 Author Share Posted June 1, 2022 Yeah....I know.... I guess I got too excited. Wanted to hear it run before making a decision on what to do with it. Marriage is Rocky and I don't believe I'll see this machine through. Quote Link to comment Share on other sites More sharing options...

brian falcone Posted June 2, 2022 Author Share Posted June 2, 2022 I'm going to the machine after work today. Forgive my ignorance . This motor is very different than what I'm used to. The starting valves, all I can see is the round metal "cap" and 3 are pushed down flush with the top of the head. Are these just caps? They spun but will not pop up. If I remove the rack I'm assuming these caps will pull up and I will have access to the actually valve below them ? It did run great on gas. Started instantly and there was no knocking or smoke.

brian falcone Posted June 3, 2022 Author Share Posted June 3, 2022 Ok. Took the rocker arm assembly off this morning. Removed the 4 caps and sprayed the valves heavily with wd40. Went back after work tapped each one with a brass rod and hammer. The 3 stuck ones popped right up. Poured some oil in there,reassembled and it started right up on gas. Waiting a few minutes and it switched right over to diesel. Minimal grey smoke . Let it run for 5 minutes or so . No knocking no pinging. And it idled very well. So. Now onto the hydraulic pump cover. I have not removed it yet but does anyone know if the inside is recessed for the gears or is it flat. Either way I'll take it to a machine shop and see if they can make a new cover. Thanks for the tips 1 Quote Link to comment Share on other sites More sharing options...

Thanks for the tips being in cali rust /carbon was the likely cause for sticking,and being a 6, may have not been abused too much. if the uc is tolerable ,try it out for a while....some work to remove pump ...? oh DSS so not practical for short use without attachments... Angry sailor could punch out a cover between burn outs. fp smith may have or know of used.... browns etc...oldsters without internet... did we miss the REQUIRED photos? 1 Quote Link to comment Share on other sites More sharing options...
brian falcone Posted June 4, 2022 Author Share Posted June 4, 2022 I'll have pics tomorrow. At some point the machine had new berco chains installed. There's still paint on the bushings. Sprockets are good. Rollers are good. Front idler guides have been repaired 5 Quote Link to comment Share on other sites More sharing options...

mmi Posted June 4, 2022 Share Posted June 4, 2022 From here the only use/abuse looks to be too much turning WHILE leveraging .....pushing trees... at worst swap in an old high flow low pressure pump 1 Quote Link to comment Share on other sites More sharing options...

louie figone Posted June 4, 2022 Share Posted June 4, 2022 That is a very nice looking TD6, it looks very straight and not abused. This is the first one I have seen with the sprocket drive housing shields. That tractor is a keeper. Quote Link to comment Share on other sites More sharing options...

brian falcone Posted June 4, 2022 Author Share Posted June 4, 2022 Also need to repair this..I'm assuming it's from when the barn caved in on it. Also main clutch lever is frozen. My father says it can be freed up through the service cover Quote Link to comment Share on other sites More sharing options...
brian falcone Posted June 4, 2022 Author Share Posted June 4, 2022 So...next I'll see if the pump can be fixed or replaced. If hydraulics work then I'll start on the clutch....I really hope the steering clutches are free but I doubt it Quote Link to comment Share on other sites More sharing options...

ray54 Posted June 5, 2022 Share Posted June 5, 2022 Nothing special about that pump just need one real close to the GPM so you don't have to sit and wait for the bucket to lift. Hopefully the plate has all the information you need. I am thinking your in the NE part of USA or maybe on the Canadian side of the boarder? Hector Gimmal that post here at times may have one in the Montreal area. Another option is replace with a BeGe brand pump as there is a company making parts and can build a whole high volume low pressure pump. But if your willing to deal with more PSI Surplus Center hopefully would have something cheaper that can be adapted. 1 Quote Link to comment Share on other sites More sharing options...
