I received an Oliver tractor

I received my dad's old Oliver. I was told it was a 70, but looking for the serial number on the left side of the motor gets nothing but a cast number, 185220 M100.

My problem begins there and now the need to get parts. The exhaust manifold has a major (non-repairable) crack. So looking for and not finding a replacement locally leads me to getting a serial number to determine if I am actually looking for a 70's manifold.

Any help will be gladly accepted.

I cant help You much; But I am just glad to see You got a family heirloom! Do You subscribe to the "Oliver Magazine"? TSC used to, & probably still does carry the magazine. Lots of good stuff in there! Only info I can offer.
 
the casting numbers are for a 77.the serial tag will be close to the
right brake drum,or on the lower side of the dash up from the
clutch pedal.if you sent a picture would be the best way to help
you.
 
On the left side of this page, under galleries there is a section for pictures. Go there and type in Oliver and look for one that looks like yours, it will tell you if you have a 70 or a 77. Chris
 
A oliver 70 will have a brass tag on the motor I can trembler
what side it will be in the center of the motor 77 do not have a
brass tag on the motor
 


Steve,

My spec book says a 70 has a continental
engine , the casting number you posted is for
a Waukesha engine, must be a 77.

There are very few manifolds that are not
repairable .

Nice job but how is it doing under extreme temperature changes?
 

Repairs do very well as they are done with the

same material as the manifold . The weld is also

cast iron ,same as the manifold. I do not use

nickel or any arc weld rod, the arc weld will

get you in trouble, use oxy/acet.

Also a link at bottom.

You have a 77. There are several sources to get replacement parts from: Korves Oliver would be a good place to start.
 
That is some fine work. I've used brass on cast before (then peened it) but not on an exhaust manifold sounds good thanks for the info.

You are good: only the good ones know about a spray torch. I usta work for ZIA steel Man. in Anchorage eons ago. and saw the ol boy chuck a 3 inch shaft in a lathe and welded it to 100 Hp. electric motor using a spray torch.
The 3 inch shaft was on a 1900 steam powered 1 inch steel break
 

I do use a spray torch for many things , but
rarely for manifolds. I use o/a torch and bare
cast iron in stick form with flux .Many of the
jobs are preheated in an oven to 1200 degF.
I have both high and low temp spray systems.
Here is a pict of the rod and flux.

Right, right "per heat post heat" ... I just seen your post of a spray torch and that thought came to mind.
Ever heard of Missouri the show me state? Well I'm from West Virgina and you gotta ta show me 'twicet', as I hold up three fingers. :roll:

Again nice work.
