Hello all I have a 1975 450 C serial number 450 CJ 271126T, recently when I am climbing a hill either in reverse or forwards it gets to a certain point (if a steepish hill) where it won’t drive any more, almost like a clutch slip feel? Could it be a clutch issue? I’m trying to find any info on the c...

Thanks to all who gave advice on this, Jim was correct, it was a dodgy wire/connection on the solenoid/switch on the pump. I cleaned it up, and it fired up straight away!

Thanks Jim, Sorry, thinking about it when i undid the injector (the thick fuel pipe that goes to the injectors) i think i must have been turning the engine by putting the key/starter on rather than pulling the primer lever. I get a feeling it could be an electrical problem and i will look at the sol...

Hello all, my 1975 450C was running fine, for some reason just before i parked it up i revved it up a bit before switching it off (dont ask me why) then went back to it an hour later and it wouldnt start, turns over fine, just not firing up. If i spray some ether into the air filter it will fire up ...

Hello, I have a 1975 450C crawler and I need to replace the starter, apparently it is easier if you remove the front skid plate/belly pan, I have removed the 4 bolts down each side, the ones on the front were missing, but I realised there seems to be some more bolts at the back, round headed bolts w...

Thanks Bruce and Jim, starter ordered. Thanks again very much appreciated. I think i may have a wiring issue with the starter so i am going to look at re-doing that as well so i will see if i can locate a wiring diagram from that link.

Hello All, i have a JD450C (1975 i believe) the serial number is 450 CJ 271126T Im in New Zealand and my starter seems to need overhauled, (cranking VERY slow and wont start it) and the solenoid gete VERY hot. I would like to purchase an aftermarket spare starter while i overhaul the original one, i...

Thanks Jim, Yes i got the manual from that link thanks, that helps tremendously. Thanks for your time and help on this.

Thanks Jim B and all those who responded, this has helped a lot. Next question (i may need to start a new thread) i want to lubricate my rollers, im getting conflicting info, some say use corn grease, others say Track Idler roller lubricant (cant find the specs on that) but i have the flat style but...

Thanks for all the info in this tread. I have just purchased a 450C (1975 i believe) the serial number is 450 CJ 271126T i can see where the clutch filler holes are (just above the tracks in the triangle recess - 1/2 inch socket square plug) cant quite find the drain plugs but will check further, bu...

Hello All, this is my first post and my first ever JD Dozer. I recently acquired a 1975 JD 450 C, it runs and drives good but does not turn right well, I’ve heard all about the belts and clutches, and been on YouTube and watched hours of videos on how to adjust the brake band/clutch. The issue is my...
