You are right, seems like a pin is missing on the other side and there is a slot in the worm wheel as well for this pin. I am pretty sure I did not lose any part, maybe the previous owner had serviced the pump and misplaced it. But one pin will still do the job of making the cylinder rotate with the worm wheel.
Awesome video! Quick question...when I tighten the nut on the end, the plunger will not move up and down unless I turn the cam part. When the nut is loose, it will move up and down. Any thoughts as to why this is happening?
Thanks! I don’t understand what you mean? The cam rotation is what causes the plunger to move up and down. So what you say seems like the pump is working as it should
Bro, the small oil (plunger)seal has one flat and the other side is grooved. Can you please tell me which side should be facing outwards? In the video, I can see that the plunger cover seal(big one) has the grooved side facing outwards. Thank you.
Hi Mjshaheed! The plunger seal should have its grooved surface face the inside, so when you dismantle the pump, you should not see the groove until you remove the seal. Hope what I said made sense!
Have a look at these videos, the pump plunger has to move up and down when engine is idling. Also, take out the oil feed lines from the carbs and make sure oil is dripping from these pipes. Also when you pull the pump throttle cable, the dripping has to increase. czcams.com/video/8aaNKoTnZVY/video.html czcams.com/video/Cm1sheTGN3s/video.html
Hi, I want to check if the oilpump of my DT250 MX is mechanically working but when I rotate the kickstarter I cannot see movement of the plunger. Is it only visible when the engine is running or should I see it when I rotate the kickstarter 5 - 10x?
Hi! I think it’s better to check the pump when the engine is running. Or else you will be cranking the engine many times to see the plunger move. Don’t rev the engine though as it can seize if the pump is not working. If you want to test the pump while revving the engine, I suggest pre-mixing fuel with oil. The plunger motion should increase in frequency as you rev the engine.
@@seventiesmetal8673 Whats the proper way to check if pump is working while engine is running.. thanks in advance for any help.. just bought a 1973 RD350 thats been sitting for years.
Hi! Check the below links. You need to check the stroke clearance of the pump, bleed the pump and also measure oil quantity coming out of pump. www.aircooledrdclub.com/smf/index.php?topic=54477.0 www.aircooledrdclub.com/smf/index.php?topic=45539.0
Thank you! I couldn’t find a video that dissects the actual oil pump components for these type of bikes until yours, very helpful
Thanks for the awesome explanation. Finally got the oil pump of my Yamaha RS 100 working with your help. Great content, keep it coming!
Nice Video, thanks.
Amazing videography and bgm along with TOP class editing. Are you doing all this yourself ?👍🏽
Great content. Haven’t seen new videos recently. Is the bike holding up well ? How about a driving video ?
Thanks, yes, I am rebuilding the engine, was not so healthy, will start uploading videos soon!
@@seventiesmetal8673 thanks. A good long drive vlog would be really nice. There's hardly any RD350 content on CZcams. You have all our attention

I have question regarding the cylinder with cam profile @4:35 is there only one pin shouldn't there be two pins ?

Bro make video how to change the oil seal and how pump works after the rebuild
Sorry, did not manage to film the rebuilding of pump. Will try to upload a video of the pump working though!
Seventies Metal waiting brother for the video
Any idea how to view if the pump is functioning well or not in-situ?

Oil pump working conditions pls help plsss
Excellent video. Is it expensive for parts to rebuild?
I buy all RD parts from www.yambits.co.uk ... the parts are a bit expensive but it’s one place for all your needs and the quality is good 😃
