510 Goon finally on the road

01 September 2017 - 04:40 PM

We don't live in a perfect world. But it's pretty damn close when you're driving a Datsun! The Weber 32/36 DGV helps. Manual choke.  Crazy loud glasspack exhaust.

Thank you to all Ratsun peeps who have given me valuable advice on the path of getting this bucket from field find to ugly (but running) duckling.


Clutch Hose Line unfreeze hack

20 August 2017 - 07:21 PM

Here's the hint from Hell, Louise: Those stubborn clutch line fittings to slave and master cylinder. Somebody recommended heat. I tried my mini propane tank nozzle firuing it up but it flamed out either when it fired up the saturation of liquid wrench or because, as the canister said " use upright". So I still needed to heat it. Here's the hack: I took a six way electric strip and plugged in two soldering irons and held them on the joint for what seemed a long enough time. Voila! 45 years of seized junction cracked open like Madonna on a Saturday night! 

I'm a genius!


Braided Steel Clutch Line

05 August 2017 - 01:11 PM

Back in 2010 there was a thread  in which Quick510 suggested an Ebay link  [ http://www.ebay.com/...b94b#shpCntId ]  that I just followed for a line from Clutch Master cylinder to slave cylinder. It is for a 240sx, but it seems that Ratsun members have successfully used them.

 

I am trying to avoid the whole steel tubing cut flare, etc. The link is for First1Racing out of China and it is for a 52" braided steel flexible line for $35 OBO w/free shipping. If anyone has used these, is this the standard thread on either end for stock 510 Master and Slave cylinders?

Any issues?

That junction between short rubber slave hose and steel hose back to Master is giving me grief!

 


Hitachi Fail in 720

09 May 2017 - 01:37 PM

My reliable 80 720 started misbehaving. It got to where I would have to rev it way up 7000 ish and slowly let the clutch out to limp it home two blocks. My son came over and (he has better eyesight than me) discovered a freaking 12mm nut in the bottom of the secondary chamber!!! Not the side with the choke on it. I have no idea how this bolt got in there. 

With the nut removed, the idle returned to normal (it was high) and it revved normal, so I decided to give it a test drive. Result: Fail. It still did the same thing and I had to push it home (1 block).

Full disclosure. When the truck was progressively losing power I blasted the carb (with motor running) with choke and carb cleaner.

I appreciate any help with this bizarre problem.
