Indian GP Engine Build Part 13

Chaincasing assembly

Friday and Repco send a text to let me know that they have the ThreeBond in, so I collect it and fit the flange. Unfortunately, after a weekend away down the coast another leak-test fails! Off it all comes and back on it goes, using much more ThreeBond this time.

The instructions say to leave for 12 hours before leak testing, so time to pick up some other jobs. Double-checking the chain I decide it's too tight, so loosen it a bit. This time I also use a tab washer. Well them nuts are right in the gearbox...

The next job is to assemble the various kickstart piston components. 

Although this is a GP it has always had the seperate kickstart ramp, rather than the one built into the end-plate. Not sure if this was normal with later Indian engines or if AF insisted on it...I guess the ramp position based upon some marks that show where it was fitted before. At this stage I just loosely bolt it down in case it needs moving later. I'm using one of MB's Allen headed pins which I hold in place with some low strength thread-lock. A simple trick from Sticky's manual is to hold the kickstart shaft in a soft-faced vice and then turn the chaincase cover until the pin can be fitted after pushing the piston down.

Now to fit the external rubber stop and kickstart. I'm fitting this Series 3 engine in to a Series 2, to start with anyway, so have bought a new kickstart that is designed to clear the Series 2 bodywork. The position on the splines/ramp is perfect.

I can now bolt the ramp down permanently. With the kickstart fitted I use the big vice as a third hand, and a mallet as a fourth hand to hold the kickstart down while I get to the two bolts that are normally covered by the ramp. The middle bolt was too short and hence got replaced by a Triumph one that I had lying around. If I could be bothered I'd replace the other two as well, the quality of these Triumph ones being noticeably better.

Now that the piston and ramp are fitted I can check that everything clears the AF 5-speed box okay. The AF instructions say to fit a gasket and then check if the chaincase cover sits flat. For a first check I figure that it's quick and easy to see if the cover sits flat without a gasket, which it does. Sweet. To be sure I use some blu-tak to see that the kickstart clears the kickstart teeth that are on first. I don't have plasticine as recommended by AF. 

My phone goes. It's my agent (pimp). Can I get a tailored resume to her today? Bum, bugger, but I need to go back to work. Anyway, I'll fit the clutch lever before heading in. Quick and easy job. Err. I have a pile of bits and no obvious way to put them together. This must be in Sticky's manual somewhere but buggered if I can find it. I dig out the old Lambretta manual, which has a picture that still bears no resemblance to the bits I have.

After hunting on the internet I find a video that shows exactly what I need to do, so nearly an hour later it's done. Flipping heck, I'd just assumed that would be a simple job.

I'll leave bolting the cover down until everything is leak-down tested...
