Re: Diablo Shop 503
To recondition your dash, clean it with thinner or other prep liquid. I really like this Prep All. . DSC07070.JPG . If you have cracks, you can use fiberglass or other plastic adhesives to fix up a dash. If you have a piece broken off, that is far more difficult to fix. Once fixed up, you can paint ...

Re: Diablo Shop 503
Once the secondary clutch is on, you can put the hood mount on. Grind off the paint on the ends of each hinge loops on both the hood mount and the hood. . DSC07066.JPG . For a replacement hinge pin, I use a piece of 2mm stainless rod. Sharpen one end of it. Then slide it through the hood mount and b...

Re: Hirth 54R (500 & 502) & Hirth 190R (503) Differences
Well by golly, I just found another possibility! Cylinder heads are not all the same! When looking at literature, I see 54R, 190R and 191R motors all have 75mm standard pistons and 68mm strokes. The 54R, 190R and 191R are listed at 15HP, 16HP and 19HP respectively. Now I can see how the larger ports...

Re: Diablo Shop 503
Thank you for the encouragement Robert. On to the Secondary Clutch: To get the clutch apart, it is best to use a press. But if you have to, two guys working together can get it apart too. . DSC07063.JPG . The secondary shown is an updated NOS secondary with bolts for the pins and set up with more sp...

Re: Diablo Shop 503
Back on her feet again! . DSC07049.JPG . The 503 has a chrome bumper, chrome half moon handle and chrome thumb throttle. If you have priced re-chroming parts lately, you know what a shocker this is. . DSC07053.JPG . Now is a good time to install your exhaust leaving the clamps loose till you get the...

Re: Diablo Shop 503
For tracks, lay your two tracks on the floor and compare them for being straight and their length. I measure my track lengths rubber to rubber (not including the metal lacers) and have seen tracks less than 105" and more than 107". I believe depending on the conditions they were stored in that they ...

Re: Diablo Shop 503
Now install your gearbox into the chassis. This is a good place for a word of caution. :!: If your track adjustment bolts are out too far, the tops of the cogs of the drive sprockets can catch on the sharp metal tube in the chassis and literally shear the tops of your cogs off. Look downward through...

Re: Diablo Shop 503
For restorations, I always put new reproduction drive and idler sprockets on. Going through all this work, it would really be a shame to have to pull the gearbox again to replace a drive sprocket. Idler sprockets are a little easier to replace, but you still end up laying the unit on it's side and s...

Re: Diablo Shop 503
When putting the new bearings into the track adjuster blocks, just tap them on the outer race of the bearings with a hammer and walk them into the block. These blocks are very hard but also very brittle and pressing a bearing into them sometimes cracks the block and then you need a new one. Often yo...

Re: Diablo Shop 503
The typical upper aluminum spacer is just straight. If you have not noticed by now, there is no seal in this area. Another potential problem is if your E-clip ever pops off your secondary clutch while you are out on the trail, the clutch slides off the shaft slightly and this allows the top gear to ...
