3TB/3AJ Engine in DJ02 frame? (XT600E)
 

Hello everyone,

As you guys may have see already I have a XT600E 1999(DJ02) with engine failure, I have been looking into replacing my engine for an engine from a 3TB or 3AJ model since this would be a cheaper and easier option(I can get the 3AJ for only 125 euros) however I cant really find any information about if this is even a possibility?

well, before leaving answers, maybe tell us what happened after your "engine knock" post....


four people answered you but you never followed up... or said tnxs...not nice

mounting points for all 600 (and also water cooled 660) are the same across the model range. you might see electric or clutch actuation differences, but thats easy to solve



BUT, main problem I see is that good xt600 engines go for at least 500 euro and way more too.

I would be VERY suspicious of an engine sold for less than 1/3 the "regular" price, it could have even worse problems than yours. ask yourself why it is so cheap... try to get is from someone who gives you a few weeks guarantee.


opening your bad engine might not be a bad idea, maybe it can be fixed for a lot less that 500 and at least you know how it is inside.

Well fingers crossed, i have purchased a xt600 engine from 1999, it looked pretty good on the pictures. surely it must have a little more life in it compared to my 64000k possibly oil starved engine:unsure:

So i just drained the oil and this is all that was left..

Primary gear nut is solid, not moving at all, no play..

well, the oil in an XT sits in the tank, not the engine.... so did you run without oil in the tank or maybe there was an obstruction in the line obstructing the flow?


in any case, wash very well the oil tank before connecting the new engine oil lines. you dont want any metal debris left in the tank from previous motor entering the new one. flush it well with kerosen or diesel

This was after letting the engine warm up, the oil level in my xt was VERY low

....and to add to that, dont forget to pull out the frame oil tank filter at the bottom of downtube and check/ clean. These are normally very tight if never been out before.
