Allis CA

Some stain marks in the cylinders from setting. I think I am going to pull the pistons, hone the cylinders and install new rings. 

Not much happening here, pulled the Allis WD45 last night and it did not run good! Very disappointed. But unless we stay on the coach all day stuff happens.

Today we should be getting a new great Granddaughter. Her name is Cassie. Man I hope she will like orange tractors!

I just don't like the look of the four puck clutch disc. I think its just the amount of surface area?? or lack of? Anyone have info on either clutch disc type? Both are sitting here on the bench. Also I have been told that the puck type doesn't work good if slipping? May damage the flywheel. I don't know, only things I have heard. Open to suggestions.

 Good to hear from you! Thanks for the suggestions/recommendations on the clutch plates!

 I won't be close to the 40 HP so I will go with the standard clutch plate. 

As I took the pistons out of the block today I noted that these are marked AE on the top.

In speaking with Brenda at Sandy lake she mentioned that these would be newer pistons not the original. I plan to hone the cylinders and install and new set of rings. (while I am in there) 

As I rotated the crank I noted that the holes/ depressions, in the center of the rod journals were full of semi hard gunk. Like old grease. The hole is about 3/8 dia by 1/4 inch deep. Is this part of the oil passage system for the rod bearings? If so, then I need to pull the cranks and clean the oil passages. I remember doing something like that on the 45 crank. 

I also noted that the cam lobes look a bit worn! Should that be a concern? I did not pull the cam. Not sure I know enough to measure one correctly. But that looks like it might not be the best.

We went to see and hold our newest great grand daughter tonight. Less than 24 hours old she was amazing! Doing all the things beautiful little girls should do at that age! Would hope to be around when she is ready to pull this CA!

  One of the blowhards insisted he had a CE block in a B puller that he had built with extra stroke and bigger bore. While on a westward trip, I took a 100 mile detour to have a visit with this person. The engine that he claimed to have pressure oiled rods had an inspection hole big enough to pass a softball into just under the magneto. Then he proceeded to claim he had other CE blocks that had pressure oiled rods as well. I insisted that he pull a rod cap and try to run a wire through the hole, after he tried this, he found that the hole had a bottom and did NOT go all the way trough to the main bearing. Next when I asked him to explain the rod oiling holes in the camshaft, he thought they were for piston cooling, really in a CE block! Then I asked why the hole in the rods? If the rods were pressure oiled wouldn't the holes allow loss of oil pressure?

After that the claim that BE/CE blocks had pressure oiled rods died.

 If you would be interested in a high lift reground cam for your CA, I still have a couple that were reground by the Preacherman of N.C. who has sadly passed on. In all my years of pulling the CAs I've tried many different camshaft grinds and none did what his can, most were less performance.

 As I mentioned in my clutch synopsis above: A heavy springed pressure plate will quickly ruin the thrust bearing in a BE/CE block. Aftermarket clutch rebuilders will claim that additional spring pressure will be better for the clutch disc, however it has an averse effect on the thrust bearing.

Well we have made some small moves to get items to bring this CA engine back to working order sometime in the future. A reworked cam and lifters from Paul will get things started. Some things to learn to get that set up correctly. Lots of measuring of the crank journals and the cylinders and pistons. Sandy Lake (Brenda) has helped figure out some of the other components to refurb this engine. New rings have been checked in the bore and the end gap is within the specs of .007 to .017 inches. pistons are being cleaned up. I will hone the cylinders to get a good surface. A new set of main crank bearings at .010 under should tighten up the thrust. So those are on their way also.

The head and flywheel are at the machine shop for improvements. New clutch and pressure plate and complete gasket kit is ready for being included in the assembly.

I am going to clean the block or take it to be cleaned. All the tapped holes in the block have been chased and cleaned out. 

The electrolysis tank needs to get set up again to help clean some of the engine items, like the pan and the front cover. I did get the new stud installed in the front of the engine, replacing the bent one (from when the block fell on the floor).

I will try to get some pictures loaded. Yea lots of work to do on this tractor. 

Tractor pull tomorrow at local show grounds. If the weather is good we will get to pull a stone boat loaded with dirt as the weight classes increase. I am taking the WZ with a bunch of weights loaded on it. Man the jib crane works great to install these weights. Will try to get some pictures too. Kind of a fun pull to let off steam and earn bragging rights.

I am planning to use the std clutch plate as my Hp will be near stock.

We had fun at the dead boat pull today. Not many tractors as the weather was iffy and folks just don't attend if the weatherman says rain.

Probably had 30- 40 hooks. I pulled in 3750, 4000 and 4500 lb class with the WZ. The clutchs are not good in this old Allis but I was able to pull the flat boat loaded with dirt a little farther than several other tractors when loaded up for the 4500 lb class.

Its wasn't pretty but the old Allis got it done!

Thanks to my wife for tolerating me playing in the sandbox with the guys!

  Take a straight edge and measure back to the throwout bearing from the face of the bellhousing, this should be 5". This gives good thread contact on the clutch rod. I have the tab on the jig set to be 4-7/8" from the block face. This give 1/8" clearance at the throwout bearing. This is a bit tighter than the 1/4" that the service manual calls for, however I've found it allows the pressure plate to release cleaner. After installing the engine, I might need to give the clutch rod a 1/2 turn or so to get 1/2" free travel on the clutch rod (not peddle travel).

I did get the CA cylinders honed, Much better. Also did some cleaning on the block. Cleaning pistons, thinking about cams. I did fire up the E-tank and have the CA oil pan in there for cleaning. 

Car shows with the 65 Comet and getting ready for tractor pull Monday night with a test of the WZ. Hope that works out with Cheryl, it is her birthday!

 A couple minor setbacks in the area of CA parts. The bearings are re- ordered. They came as incorrect components. A new set of rings were ordered as one of the oil rings was only 1/2 there, the broken portion was missing. I still have many moves to make, so this is not going to really hold up the project much. I have several full days of cleaning parts and nuts and bolts! 

Some cam shots:

Pretty exciting stuff here!:)
