'83 Triumph T140ES Refurb project

[grandpaul]

hee hee, YES!

I still have to overhaul the master cylinder, and I've already twisted and broken one tiny allen wrench trying to loosen the miserable grub screw. What a pain in the neck...

 

[grandpaul]

Here are pix of the broken and twisted allen wrenches. Applying some Bernz-O-Matic loosened that pesky grub screw.

Thoroughly polished the master cylinder bore, cleaned everything up and installed the rebuild kit with a few drops of brake fluid to lube everything. Slipped in as easy as you please!

Painted plunger body will be assembled to it in a few minutes.

Glad you got that thing out. Very good.

 

[grandpaul]

Lockheed master cylinders are a nightmare if you fail to regularly flush & clean them. I have at least 4 "dead" ones, either with corroded bores, broken reservoir studs, or stripped grub screws.

Anyway, it's all back together. Pretty significant difference "before and after"-



Nothing left to do 'till the cad plated hardware gets here, except wash parts. Oh, boy, my favorite...

 

[grandpaul]

Forgot to post the first comparison shot - the piston tops:

 

[CarlS]

A slight difference there!

 

[grandpaul]

Not much to report, since all of the hardware to re-assemble the bike is still out at the Cad plating shop...

Don't you love it when the shiny polished stuff arrives?

(I do)

 

[CarlS]

That looks mighty fine!

 

[otherwise]

Nice job done with the buffer.

 

[Sea Dog]

Beautiful work GP !

 

[grandpaul]

I only get credit for putting them in a box and addressing them correctly. The polish shop I send them to are tops.

"A man's got to know his limitations" as Dirty Harry Callaghan (Clint Eastwood) might say...

 

[CarlS]

He certainly does superb work!

 

[grandpaul]

Polishing is HOT, sweaty, sooty, tedious, tiring work.

They say time is money; it DOESN'T PAY for me to spend as many hours as it would take to polish stuff this well.

I wouldn't be able to charge more than about $5 an hour!

After polishing my fork lowers I understand completely where you are coming from.

 

[DaveM]

Paul they do and outstanding job at it as well, some jobs sure are best done by others

 

[grandpaul]

IF I HAD AVAILABLE SPACE, I'd have a small mill, lathe, boring machine and powdercoating /painting booth, but NOT a polishing stand!

One of my sorriest stories is when I was preparing to polish the engine covers of my '67 Bonneville; I had the scruffy covers, several tins of various polishing compounds, a bundle of 0000 steel wool biscuits, and several clean rags in a brand new tall kitchen trash can, beside my recliner in my TV room. One day my lovely wyfe hired a new housekeeper; one of her first tasks was to collect all the trash from the various bins throughout the house, and toss it all in the skip. That simple task, which she did quite well, cost me over $400.

It was a sign from God that I was not to be polishing motorcycle parts.

 

[CarlS]

LOL That was definitely a sign!!

Hi Paul,

How hot did you have to get it, to get the grub screw out? The plunger in my rear cylinder is completly stuck.

 

[grandpaul]

Not very hot. It's just a small bottle torch, and I only waved it around for maybe 2 minutes.

Hold the tip of the flame off the part, and keep it moving; touch it every now and then, and you'll see when it's getting too hot to touch. That's hot enough.

(you can sacrifice a tiny fingertip burn; or just keep a 6-year-old around, they'll want to touch it and you can teach them a lesson at the same time)

 

[The Seeker]

I have always found that it's not the actual heating point that helps unstick threads....but the point of them cooling down from heating that gets them to move.
