Engine conversions

[Bob Carriere]

I had the same intention as you Bob of installing the original 1959 modern fully synchro 4 speed but found it would not fit the tight space between the tranny and T case so reverted back to a NON synchro CMP tranny. I assume you have spare CMP 4 speed to install or let me know...

On the water pump...... please look at it very carefully...... you may be able to get away with and fit a short shaft 261 water pump but the location of the fan willbe very low on your radiator and MAY cause some cooling problem.... the 216 water pump installed with an adapter plate will raise and center your fan much better. It will require that you drill and tap your 261 block and is much easier to do with the engine out of the CMP. We have done two conversion at the Barn and are very please with the installation.

We were fortunate enough to locate two 6 blades 216 gun tractor fans which really suck air through the radiator.

Phil's point of matching pulley size is crucial to prevent the jet engine sound and to prevent cavitation from too fast spinning of the water pump. Pulleys also come in various belt width size..... I am running a 7/8 wide belt with matching pulleys including one for the alternator which was easy to procure at a MF tractor dealer...along with the belt.

What are you doing with the oil filter system???? Don't forget .....DO NOT RUN your engine without a filter connected or a temporary bypass external line between the oil outlet and oil intake as you will fry your engine.

I choose to install a dual PH 8 spin on filters set up hidden inside the side frame and had 1/2 lines fabricated to hook it up. I like the extra oil capacity as it doubles for the cooling of the engine.

Would be nice if you showed us some pictures of your beast!!!

Gentlemen;
I hope to get away leaving the waterpump down low but with a 4 bladed fan.if that doesn;t work I will try plan "B" and move the pump.
The original 261 had a canister type oil filter mounted on the manifold. Provided it will fit in/under the doghouse I will use it.
I like the idea of using a modern master cylinder (tucked under the floor somewhere) and would probably go for power brakes.My previous CMPs were never great in the braking department ( except for my first 3 ton with the booster) [I] suspect tghat one of the main causes of high speed wobble might the tremendous amount od semi balanced cast iron that spins around as the wheels turn. Anybody considered disk brakes??? or will this suggestion get me barred from the club and my membership torn up???

On the low 261 water pump make sure the bottom of the fan blades does not it anything.....

Brake wise.... a good totally rebuilt brake system with regular proper adjustments will lock up the wheels on my C15a anytime.

The bad brakes are usually due to leaking axle seals. ........ badly adjusted lining....... pitted drums.....glazed old linings......and lack of regular visual inspection and adjustment.

Still looking for pictures ........
