Help Please...

Just rebuilding my DT engine and the oil pipes going to and from the autolube pump are holed and need replacement.

These plastic pipes go through the engine case and use two metal 'male to male' connectors to pass through the case before connecting on to the oil tank and carb.

I need to remove these two connectors which that are inserted into the engine case to do the job properly...Anyone now how to get them out?

I really dont want to mix the oil with each tank of petrol!!

Nick, these connectors are a permanent fixture and you should not try to remove them, you will no doubt have access to the pipe connections to the two spigot's if you drain the oil and remove the clutch casing.

Thanks Paul.. the engine casing is already apart and there is no access internally to the spiggots as the nipples that receive the oil cables are hidden within the internal castings of the casing. I simply cant see how you replace the internal oil lines without removing the spiggots. you cant get in there to either remove the oil pipes or put new ones on?

Hi Nick

Just had a look on the Yamaha USA site under parts and selected DT175H which looks like the DT175MX and look under oil pump and it shows the two connectors as seperate parts so i would have thought that they are removable.It might be worth having a chat with your local Yamaha dealer to see if they are still availabe in case you damage them trying to get them out.

OK so a while back I bought a spare engine pile of poo off ebay and as it is at my workplace decided to investigate further.

Here are the oil connections in the case

And the other side with the case removed from the engine...too cramped to get access to remove the tubes

so I used a pair of vise grips (mole grips) and got a hold of the spigot like this

and then got a grip of the vise grip in a bench vise. Then using a wooden drift I tapped the casing and the spigot came free

So here it is...removed ready for a new tube to be fitted

Tip...remove the smaller spigot first and then you will have better access for the vise grip on the other

I did this without any heat although it may be easier with heat if its stuck fast.
