neilios Posted January 1, 2015 Report Share Posted January 1, 2015 As per title, this was on the magnet when I dropped the oil, any idea if it's a needle bearing part of anything else? Is it safe to ride? Everything appears to be fine with the engine. Many thanks in advance Quote Link to comment Share on other sites More sharing options...
the addict Posted January 1, 2015 Report Share Posted January 1, 2015 Wow Neil! personally I'd not run it until its identified, could be costly? Do you have a better photo and some dimensions? looks like a bearing part to me? Quote Link to comment Share on other sites More sharing options...
neilios Posted January 1, 2015 Author Report Share Posted January 1, 2015 The part is approximately 20mm long and 3mm, I thought it looked like a part of a needle bearing. The bike is an 04 Rev 3. Thanks Quote Link to comment Share on other sites More sharing options...
eddie_lejeune Posted January 1, 2015 Report Share Posted January 1, 2015 Definetly pull it apart before you ride again Quote Link to comment Share on other sites More sharing options...
neilios Posted January 1, 2015 Author Report Share Posted January 1, 2015 Any idea what it's is or where it might be from? Quote Link to comment Share on other sites More sharing options...
tt3506spd Posted January 1, 2015 Report Share Posted January 1, 2015 I would assume that it is a roller from the needle roller bearings inside the gear box time to spilt the cases Quote Link to comment Share on other sites More sharing options...
reggie Posted January 1, 2015 Report Share Posted January 1, 2015 I think this may be the drive pin from the water pump gear. Pull the major clutch cover off to have a look.Be sure to pay attention to the shims on both the gear shift and kick start shafts. Quote Link to comment Share on other sites More sharing options...
shercoben12 Posted January 2, 2015 Report Share Posted January 2, 2015 check water pump pin. sounds about right length. if not your best bet is to open it up and check all needle roller bearings and rebuild while your there. a few of mine exploded on my gasser and was rather costly!

lineaway Posted January 2, 2015 Report Share Posted January 2, 2015 I would check the kick start idler gear (That would be the easiest) but it would make more sense that it is the bearing that the kick start shaft slides into. Quote Link to comment Share on other sites More sharing options...
neilios Posted January 2, 2015 Author Report Share Posted January 2, 2015 Thanks for all the replies, looks like a closer look inside the engine is required, I will let you guys know what is found over the weekend. Quote Link to comment Share on other sites More sharing options...
pa. Posted January 2, 2015 Report Share Posted January 2, 2015 Looks like the coolant drive lock pin. Part 67 on page 3 on the parts diagram. http://www.trialsport.com.au/beta/Parts/Rev3%20250_270%202004.pdf Quote Link to comment Share on other sites More sharing options...
jfc Posted January 2, 2015 Report Share Posted January 2, 2015 As above looks like the water pump gear drive pin, quite an easy fix if it is. Quote Link to comment Share on other sites More sharing options...
neilios Posted January 2, 2015 Author Report Share Posted January 2, 2015 Thanks all, I found the diagram and printed it off, the water pump pin is the same but it has one installed. A quick chase through the history and it looks like the previous owner bought a pin by its self so he must have dropped it in the engine when the water pump case was replaced, looks like I have been lucky that it was caught on the magnet for the drainer. cheers again it's been very useful to have all the comments and guidance. 1 Quote Link to comment Share on other sites More sharing options...
lineaway Posted January 2, 2015 Report Share Posted January 2, 2015 According to the parts list the water pump pin is 12mm long. I hope it is that pin as it is easy to drop if you are working with the bike on it`s side. Quote Link to comment Share on other sites More sharing options...
neilios Posted January 3, 2015 Author Report Share Posted January 3, 2015 I rode it for 20 mins last night and it was fine so off to the trial tomorrow and I hope it's OK. Quote Link to comment Share on other sites More sharing options...
