- Where do you buy a main bearing line boring jig , the kind that bolts on the block and powered buy a half inch drill.
- Post by E.
- Pictured above is a pair of Kwik-Way LBM main bearing align boring bar centering fixtures positioned on the bearing saddles in a pan rail section for illustration of a Model A engine block.
This special relationship lead to a factory approved standard for. Dealer rebuilt engines were known as "Wilsonized" engines. These rebuilds had the reputation of holding up better than. This reputation was well earned because Ford, Wilson and the Babbitt companies worked together to make this process successful.
KR Wilson had made some of the tools that were used in the actual production of the "A" and was in a unique position to modify them for dealer use. The dealers also had been. This technique and information was not available to the general motor rebuilding trade. We do know now from hindsight that it was in fact the method that held up best. Pouring Babbitt into a cold saddle still runs.
That neither the block nor jigs be heated for cast iron components prior to the Babbitt pour. They had metalurgical proof that the Babbitt had the best chemical and physical. Ford Babbitt was composed of 3 metals, Tin, Antimony and copper.
The melting points of each of the metals is different tin deg. The "chill pour" method was important because if the molten babbitt does not solidify cool rapidy the metals seperate due to.
Wilson stated it this way "the copper could solidify while the tin. This would cause the metals to seperate and make an unacceptable weak bearing. The result will be a bearing which will not hold. Heating componets that can retain heat will contribute to this negative effect on the babbitt and adversely affect the cooling rate of the babbitt.
Even today many vintage. The block should not be tinned. The "A" engine block as well as any cast iron block that has been used becomes "seasoned".
Its pores become saturated with oil. Heating the. During a pour this vaporizing oil causes porosity and blowholes in the Babbitt. The plain fact is a. Heating the block with a torch.
It is also for this reason you should cut out the old babbitt rather than trying to melt it out. There are two reasons for this. They had to do with the chill pour. Immediately after the pour the babbitt would shrink away microscopic in size from the cooler surface of the block. Peining stretched it back in place. Secondly it insured good contact with the bearing saddle. Good adhesion is. The peining is done while the bearing is still warm and soft. The illustration. The front face of the rear main bearing thrust face were established with a set of jigs.
When the engine was manufactured at the Ford plant the rear-bearing cap holes were used as. It was and is important that any. The left pictures show the drop in jig which. The flywheel housing case which attached to the block had to be miked to the flange of the crank. Because mis-alignment of the case to the. The lack of understanding how important this step is, has probably accounted for. If the above issues where observed and the procedure followed the rebuilt motor was considered to be "Wilsonized" and did in fact enjoy a longer life.
The striped block must be boiled and pressure checked and your crank magnafluxed, ground and miked. Before you send out your block check both the top surface of the block as well.
If they are not flat its a good idea to have them ground decked so they will be flat. This can help eliminate some leaking head gasket problems. The exhaust seats will be put in. The bearing boring bar is setup on the block to remove the old babbitt material. You can use the KW Wilson setup or Kwik-way align boring equipment.
However if you do use the. Wilson setup you must modify the bar to accept adjustable cutters. Originally the bar itself had fixed cutters which were made for standard cranks that were obtainable from the factory. You now need adjustable cutters. I dropped a ball bearing. This way you can hold the cutter in either drag tight fit or solidly tight. You can set the depth of the cutter in.
The HSS cutter is ground. For the babbitt removal stage the cuts should not be greater than. The bar is bolted to the block with its frame resting flat on the bottom of the block and against the dummy camshaft. The caps are fastened to the block with. Wilson quick bolts. The KR Wilson machine is.
The cutter will progress through the bearing at 25 rpm's. Repeat till the process is completed on the bearing. Do each bearing separately. Finally take a small cut into the cast iron. This brings the saddle to new metal.
You need to be cautious here look to see if any rebuilders have done this before. If it looks like the cast iron. Drill out any Babbitt in the anchor holes.
You can add two more dovetailed anchor holes if you like. Take a steel wire brush connected to a drill and. If you don't have a KR Wilson machine the boring can be done with one of the other commercial align boring machines such as the Kiwk-way.
If the Kwik-way is used you will need to. Unfortunately they are no longer in production. Thus unavailble from Kwik-way. You are now ready to pour you bearings in the block. All the oil holes must be plugged with damtite, a material which will not melt, it is pliable and will stop the molten Babbitt from.
For this step use the KR Wilson jig with the pouring blocks. The saddles should be clean but not tinned as explained previously. Each bearing should be poured. I find it easier to remove the jig that way. You will also need at. Prior to placing the mandrel on the block I heated the jig with a torch to. Place the mandrel on the block.
Raise up the cross arms a little with hollow washers. This is done for two reasons, first the bar was. Now bring the first set of collars up to the block where you will pour the first bearing. Repeat this procedure as you pour each additional bearing. Wilson sold a gasoline tin melting rig but I would not use it because of the danger it posed. Originally I was going to use a propane plumber's pot but I was also concerned about the.
Finally I got an electric Babbitt pot which I feel much more comfortable with. The Babbitt is poured from two ladles one on either side of the saddle or cap diagonally. Don't overfill the dams as they will then be very difficult to remove. Preheat the laddles before you dip them in the babbitt. A word about safty here is necessary.
If moisture comes in contact with molten babbitt it will. The Babbitt is heated to cherry red and checked with a pyrometer to be between degrees.
There is a front locating fixture and a rear fixture, which are similar but different. The corresponding hole at the front bearing saddle is also designated as a datum for block machining. Also shown are the pan rail parallel bars on which the Kwik-Way LBM boring bar support bridges are mounted bridges not shown. Where do you buy a main bearing line boring jig , the kind that bolts on the block and powered buy a half inch drill. Thanks, sunny. There are often dark imperfections in the machined surface with reused babbitt, which will cause abnormal crankshaft wear. The bar diameter should be smaller than the standard size Model A crankshaft, perhaps 1.

Welcome Guest Sign In Register. Main bearing babbitt mold. Does it come with instructions? It does not come with instructions but we can help you with any questions you might have.
It can do both the block and caps. Answered By: 23 SEL 14 out of 17 found this answer useful. I Found this information or. Does this mold have something to block off the oil passage holes for when you pour the Babbitt? This item does not include a piece to block off the oil passage holes.
When Ford originally poured babbitt bearings there was no oil hole and these were made to Ford specs. There are not supposed to be holes in the cap itself, the oil goes in the groove where the cap is split against the block.
Answered By: 21 AEL 7 out of 10 found this answer useful. What is the ID of the as cast hole after pouring with this mold.
I have a TA Tobin Arp line boring machuine and i need to know the hole size and also how do you control the gear mesh of the timing gears. When figuring out the gear mesh you need to space the boring bar from the camshaft to get the correct. Re: Babbitt Pouring Fixture? Somebody actually reproduced some a few years aog. Once the babbitt is poured, how will you align bore the rough babbitt to fit your crankshaft?
Are you looking for fixtures to pour connecting rods as well? What type of babbitt are you planning to use? Unknown babbitt properties like the amount of antimony that is lost each time that babbitt is melted, cause babbitt to become brittle. Brittle babbitt causes cracking at the thrust flanges. Thrust babbitt cracking is also from the result of misalignment of the flywheel housing to the block.
Reusing old babbitt often is much harder to machine to a nice mirror surface. There are often dark imperfections in the machined surface with reused babbitt, which will cause abnormal crankshaft wear. This mixture was used throughout Model T production.
Then when the Model A went into production, Ford began using lead babbitt instead of tin based babbitt. The thought was that the smoother running Model A engine could handle the lead based babbitt, with the larger diameter crankshaft and rod journals.
When the Model A engines went to the dealer for rebabbitt, dealer's often used whatever their local supplier had to offer. The Tin based babbitt holds up to the pounding of the combustion strokes much better than the lead based babbitt. Lead based babbitt has a tendency to crack at the thrust flanges quicker than the tin based babbitt.
Lead based babbitt will pooch out of the center mains and the rear mains, especially when the crankshaft is warped.
Most Model A vibration issues are from crankshaft grinders who do not know how to machine a Model A crankshaft. When the Model A crankshaft is measured on a runout fixture, it is not uncommon to find the center main. What about the thrust journals of the crankshaft? The crankshaft must be aligned perfectly in the block from front to rear to allow the correct alignment of the camshaft gear.
Misalignment of the camshaft gear is often the cause of Model A engine power loss, constant overheating and poor running. With the gears cut on a helix, the alignment of the crankshaft is critical in the Model A block. KRW made tools to measure the thrust and align the crankshaft into the block correctly. When a flywheel housing is installed without checking it for out of lateral alignment, the transmission input shaft will be in a bind in the pilot bearing, causing the end of the crankshaft to flex each revolution, the flexing is transmitted to a warped center main, which in turn beats the center main babbitt out of the cap and block.
A cracked flywheel housing can not be made to be in proper alignment with the engine or the transmission. Cracked flywheel housings are common. When the Model A crankshaft is machined true, and balanced and when the flywheel housing is properly installed and is square to the block and is no more than. ASTM designations are used these days for determining the various type of babbitt mixtures.
High speed diesel babbitt often uses nickel, which can be harder to machine. It is very durable and is tin based. Any good tin based babbit should be fine. Magnolia metal company is known for their lead based babbitt. I do not use any Magnolia babbitt. A common name that used to be used years ago was Government Genuine Babbitt.
That was a tin based babbitt, but the name Government Genuine is no longer used with most metal companies. Do a google search for babbitt suppliers and you will get a listing of metal companies to choose from. I only use the original Model T based formula and have had excellent results. Customers do not come back for babbitt failure problems. There are several fixture manufactures to choose from. Quik Way made a pouring fixture that had the oil channel made into the mold.
Some people like them. I like the KRW fixture the best, as all three bearings in the block can be poured at the same time.
