Morning folks.
I have an exceedingly beaten up old 360 rt used as a farm bike for the past 30 or so years.
Time to actually get the old girl on the road, ie legal and stuff, as I have an oversized (tall) lad of 20 who would like to learn to ride (at last!!!) He's not a natural so I suspect this girl is the best machine to do it.
I do have a problem though. The worm actuator which operates through the left crank case cover pushing that clutch rod thingy is missing and I'm damned if I can find a parts catalogue with the actual part number and a visual on ebay has not been much help.
The engine runs a treat though, none of that pinging or knocking sound associated with old 2 strokes and is a first kick starter.
I will renovate her aesthetically also, so all advice from the experts will be gratefully received.
Photos will follow.
Regards and thanks
Dave

I got the seal for the clutch actuator Saturday. I did not get to it until today.

I removed the old seal. good to know there is a roller bearing there. the bearing is good still so it is being reused.

here is a pic comparing the new seal with the old one.

the DT400 head gasket goes right on.

I need to get the engine into a bike before I do the final torquing of the bolts.
these are the gaskets I used.I have used this company's gaskets before when I built the engine in the 1979 CR250.

I went ahead and stuck the head on. it is not far away from being fired up for the first time in several years.

I have to wait until the Boyesen reeds and that seal for the clutch actuator to show up. might put it in the extra DT400 frame I have to light it off and hear it run. and oh yes,there will be a video of the first start up when it happens.

I still have to wait until that clutch actuator seal shows up. I went ahead and reassembled the engine to a point.
when reinstalling the kick start lever,it helps to remove the idler gear that goes here. I wound the spring 1 turn and pushed it home.it is not documented but I also reinstalled the decompression cable.

I cleaned up the steel clutch disks before putting together,this is how they looked before. going by how nasty the steels are,this engine had not been running in years,years before I got it in 2011. I measured the friction disks and they came in at 2.8-2.9 mm. they can be used for now.

I loosely assembled the clutch so that when the seal arrives,I can install the bell crank with no trouble.

Hello everyone! Like probably many people here, I started riding when I was young, quit for a while for college and early work life, but got back into it in 2000. I currently have both a lightweight dualsport bike (09 WR250R), a adventure bike (08 KLR650), on/offroad sidecar rig (06 KLR650 w/Sputnik sidecar), and a trials bike (04 Beta Rev3 270). I (think) I'm about to have a 1972 DT250.. A friend of mine has one that's been sitting in his barn since forever ago when it broke the clutch actuator spool thingie in the LH sidecover and wants it gone, so that's my reason for joining here. Probably gonna need the help of this forum as I try to do a resto on her during our long Michigan winters!

Folks,
New to this board. My Name is Mark Hamersly, and I work at the border for CBP at the San Ysidro Port of Entry; I came here from the SDSO after 9-11, and was initially an INS Inspector. I started doing set-up (un-crating and assembling Yamahas) for San Diego Yamaha in 1969, and racing for them in 1971. I entered the USAF (who wouldn't recognize a Warrior if one kicked them in the &*$ (I got out after the time I was obligated to, used my GI Bill, and took a Warrant as an Army Aviator in the Guard/Reserves). I made expert, racing motocross at Cal Expo in 1973 (on a modified RT-2Enduro!), and promptly left for Vietnam. After my time in SEA, I went to Ramstein, West Germany. After three races on a borrowed Husky 250CR, I got an offer from Dr.Hans Maisch to race for the Maico factory on a 1975 250GP. Coming home, I had multiple surgeries to repair damage to my wrists after being shot and abusing them for three years of racing. So, I stopped racing and rode only in the street while working as Service Manager for American Honda dealer 1058, Valley Motorcycle Sales (now Motoworld in El Cajon). Time ahead, and many surgeries later, and after open heart surgery in 2013, my doctors OK'd a return to racing! I'm now racing Dist 38 desert events on a BEAUTIFULLY restored 1973 Yamaha 250MX, and my 'barely street legal bike, is a 1973 Yamaha RT-3, 360 Enduro, modified like I would have in 1973, IF I'd had the money (As a USAF A1C/E-3, I made $288 a month). The RT-3 now had 'modern' footpegs and a silenced original Bassani expansion chamber as well. Plus, I have a Don Vesco (We miss you Don old friend!) "Skinny Fat" tank that's being painted. I have also had the machining done to convert the RT-3 to the use of a Yamaha R-5 clutch actuator, tius no longer being dependent on the stock plastic actuator. The BEST thing about riding the 360? Knowing that when I start it, and ride down my driveway onto the street, the EPA and Cal Air Resources Board are just having FITS!
Pictures of both are attached to this. I have enough spares to keep these two running for 15 years or more.
