MASSEY FERGUSON 35x - CAV DPA INJECTION PUMP REBUILD (#2 of 2)
HTML-код
- Опубликовано: 2 авг 2024
- Second part of a two-part series on a step by step CAV injection pump rebuild on a 1964 Massey Ferguson 35x tractor to re seal it and stop it leaking .
Part 1 covers removal and dismantling, and can be found here:

These videos show how I did it, not necessarily how it should be done or how you should do it. For a more expert approach, check out Lance Maskell's excellent video tutorial on rebuilding a similar pump over at Bundy Bear's Shed:

Nice detailed video with no missing info, thanks. What an amazing bit of engineering these 'mechanical computers' are.
Glad it helped. Incredible how robust these things are. It was still working after 60 years! Appreciate your feedback, thanks 👍
Very good video Harry.. probably the best.
Regards. Thorsten, Denmark 😊
Thank you for your kind words, Thorsten. Glad you liked it.
I've been waiting for this!
In the past, I have removed the roll pin in the inlet head and using fine valve grinding paste and a piece of glass polished out most and sometimes all of the wear lines, I have also done that with an engine oi pump which had the same issue.
That's worth knowing, thanks for your feedback Roger. And welcome to the channel!
Very helpful, thank you, just got to do mine now!
Best of luck with it, Max. I'd never done one of these before and I'm all thumbs, so you'll find it a doddle. You've probably found Lance's channel on Bundy Bear's Shed already, but if not, check him out. He's got a couple of excellent videos on this pump too, well worth a look before you start.
Thanks very much
Thanks, very nice video. I rebuilt my 35X CAV pump too this spring, but now its like it won't get as high rev's as it should, I get stuck at 2000/min while spec says 2200 (35X multipower). I forgot which holes I used for the governor springs (of course) - how is your running with the "middle-middle" combination?
Hi Per, sorry for the delay in replying, we're in the middle of haymaking. Honestly, it's been working just fine. Can't say I've taken it to 2000rpm though, about 1600-1700 is all I've needed to run the PTO. Are you running a belt pulley or something that needs high revs?
@@myharrisThanks for getting g back. My main con ern is a very low idle when warn, and I was thinking it could be due to a wrong setting of the spring, so the rpms are offset so to say. I didnt touch the adjustmnt screews for the gas lever, so it cant be that whocause the low idle. I only use my tractor for cutting grass and it has enough power, so I don't need the extra ram...and they would probably be harmful for the engine too for lo gerne periods.
@@perterslse2543 Have you tried adjusting the idle screw? Might be as simple as that. From memory, the manual specifies an idle speed of 450rpm, which I have to say sounds high on mine, I keep meaning to experiment adjusting it down but haven't got round to it yet. If it's running smoothly otherwise, I'd try adjusting the idle screw. Might help with the top-end revs as well ;-)
not sure if you have fixed your issue yet, but there is a code you can use to find the right holes on your cav injection pump and there is on number on the pump that you will need for this.
first number after the forward slash. tell me the number and ill tell you the holes.
Quero fazer um curso....como é que eu faço
I need a manual
