Valentinik Posted February 12, 2016 Author Share Posted February 12, 2016 I spent a few hours on the frame this afternoon and got it finished. Rear hoop and seat mounts welded in: I also made a small battery box and welded a bracket underneath the swing arm to mount it. I just need to weld the aluminium box up Mike 1 Quote Link to comment Share on other sites More sharing options...
Kingster Posted February 12, 2016 Share Posted February 12, 2016 I was wondering where the battery was going to end up. On mine it's still in the triangle behind the tank, albeit in a nice ally box. Following with interest Quote Link to comment Share on other sites More sharing options...
Valentinik Posted February 14, 2016 Author Share Posted February 14, 2016 Thanks Chris, i like the look of the frame with nothing behind the engine so i didnt want to see the battery at all. Some people mount them to the swingarm itself. I couldn't see that being anything but bad news for the battery and power leads to it though. I've just finished blanking off all holes in the top and bottom crankcases so they can go to be soda blasted tomorrow. Quote Link to comment Share on other sites More sharing options...
Valentinik Posted February 17, 2016 Author Share Posted February 17, 2016 I made the aluminium panel for the seat tonight and mounted it to the brackets i welded on the frame. The bolts are only temporary. Mike Quote Link to comment Share on other sites More sharing options...
Valentinik Posted February 24, 2016 Author Share Posted February 24, 2016 I got my crankcases back from being soda blasted and finished cleaning them up. Tonight I put in the replacement primary shaft bearing. I just need to find a replacement oil guide as the one i've got isn't great. Quote Link to comment Share on other sites More sharing options...
Valentinik Posted February 29, 2016 Author Share Posted February 29, 2016 Progress is slow due to a lack of time and money at the moment but tonight i got half an hour to start building the top crankcase up. I got the shift drum and shaft installed and starter gear (not sure if this is the correct term for this?) Hopefully tomorrow i should get both the main and secondary shafts in and check it selects all five gears ok. Mike 1 Quote Link to comment Share on other sites More sharing options...
Kingster Posted March 1, 2016 Share Posted March 1, 2016 Mike - while you have the opportunity, check the thickness of the selector forks where they engage in the gearbox (on the ends of each fork) as that is where they wear. If there's a lot of wear it can drop out of gear. It's not too common a problem tbh, but worth checking. However, not sure what the tolerances are! 1 Quote Link to comment Share on other sites More sharing options...

Il check them before I go any further. Quote Link to comment Share on other sites More sharing options...
Kingster Posted March 1, 2016 Share Posted March 1, 2016 Oh - and when reassembling the crankcases, take care to ensure the small dowels in the top case (gearbox shaft area) align with the holes in the bearing cups - sorry if I'm stating the obvious, but have seen people mis-align them, then try and force the cases shut and wondered why they wouldn't! It's great to see an old jap 4 in bits - takes me right back to the early 80's! Quote Link to comment Share on other sites More sharing options...

It's great to see an old jap 4 in bits - takes me right back to the early 80's! Thanks Chris, i must say i'm really enjoying the rebuild, it definitely won't be my last. I suppose i'd best look in to learning how to ride and taking my test. Tonight i got the main an secondary shafts in place. I ran through all 5 gears and each one engages smoothly, so the transmission is done until the cases are reassembled and i put the primary and starter clutch in. 2 Quote Link to comment Share on other sites More sharing options...
Valentinik Posted April 4, 2016 Author Share Posted April 4, 2016 Other things have stopped progress for a while but i found a set of forks on eBay complete with triple trees. They're in very good condition, the trees will need powdercoating and i'l replace the oil and seals but they're fantastic for £52 posted. 2 Quote Link to comment Share on other sites More sharing options...
Valentinik Posted June 13, 2016 Author Share Posted June 13, 2016 Not a lot of progress while i've been working on the Westie, but this week I got a chance to strip it all down and get the frame and swingarm off to the powder coaters which should be finished this week. I also bought some internals for the engine to carry on with the rebuild. Yesterday i rebuilt the primary with new dampers so that is ready to go in. No pictures at the moment but i'l get some when the frame is back. Quote Link to comment Share on other sites More sharing options...
Valentinik Posted June 16, 2016 Author Share Posted June 16, 2016 The larger bits came back from the powder coaters today. Im really pleased with the finish, its 99% perfect and only cost £96 all in. I found a prime position to start the build: The wife didnt have the same opinion on where the build should continue so it was relegated to the garage. (it made it longer than i expected) Mike 3 Quote Link to comment Share on other sites More sharing options...
Valentinik Posted June 25, 2016 Author Share Posted June 25, 2016 Following Oddjob's advice of fitting the engine to the frame partially assembled I started assembling the first few bits onto the frame. My tapered steering bearings arrived today so I've now got the yokes installed. I fitted the swingarm during the week. This is how it stands at the moment: My next job is to work out a way to hold the rear hub so i can remove the wheel bearing retainer.
