Another service, hard seats
« on: March 01, 2014, 03:06:02 AM »


Among other things the Indians dont have a good handle on is valve jobs.  The way they cut the head makes it difficult to do a nice three angle job so I have invested in equipment to install the hard seats. These are Qual-Cast products, as good as it gets, installed in a new 7 stud India head. Bowls will of course be blended and deck resurfaced before we call them done. This is a needed modification for a working engine in my opinion.

If you cant get it done locally I can help you out.

1- Clean head and parts
2- hard seats plus installation and seat profile
2-valve grind (if reusable)
2- knurl and ream guides (if reusable)
2-bowl blending to seats
1- Mill deck
1- Re-assemble
1- Return ship USPS flat rate box  continental US only please, others extra.
$100  Plus valves, plus guides if needed.

Or send your clean bare head with guides installed and your valves  $70

From the picture you have, it also looks like whoever faced off the head, had the facing tool set below centre height.

I see you have handle time on a lathe, :)
Yes the tell tale nub is there. The lathe they used must have been a dandy as the entire cut is cone shaped.

Funny, I was thinking the same thing and I scrolled down to find out others were too. I just got a little 1927 South Bend heavy 9 restored and working nicely.

Wow, they will let you ship that in their flat rate box ?  I'd have thought it was over the weight limit.  Wonder if they toss it around like the other packages ?

Ya there is a weight limit, 70 Lbs. Probably could ship two heads in one of the large boxes.

Interesting - I'd never thought of machining the head flat in a lathe.  I always thought you used a mill for that  ???

A lathe is the only machine tool that can rebuild itself.

A milling machine would always be preferable, due to ease of setting up, and holding the cylinder head.

As the OP has already stated one of the problems with facing a head in a lathe, is producing a faced surface that is concave. Even good manual centre lathes will produce ever so slightly concave surfaces (as this is preferable to having a convex surface)
