There is no evidence that this was a design "feature." White Motors fixed this shortcoming when they added a check valve to the oiling system.

I used shim washers to tighten it up and heim joints to allow for flex. No rattles.

New dampers are still available for reasonable cost. There is a hand written note in one of my tractor manuals (using their version of the multifual) indicating that the damper is to be replaced if the camshaft breaks. It is very important for the entire rotating assembly.

The old transmission was a major source of leaks for this truck. Not even a drop now.

Same casting number as the "standard one." The vendor had no idea that he had one with a seal; it just was the one that I was shipped.

This is a military surplus front bearing retainer with a seal. Purchased from a surplus vendor; no, they don't have any more.

A lot of the trailer light converters are unnecessarily complicated involving multiple relays, power from the battery, etc. This one can be done for low cost using three 5A 24V to 12V DC-DC converters. Your lights have a L, R, and tail. Each of these is fed into the 24V input of the DC-DC...

Yes, odometer and hourmeter. I finally got around to programming the speedometer last weekend; very easy.

The speedometer (333-162) and tachometer (437-152) are both VDO Vision; the rest of the gauges are VDO Cockpit. If I could do it over again, I would have used all Vision series which has better lighting. The pics make it look a little harsh but it is not. The tachometer and speedometer are...

Continental really did some interesting research back then. Of particular note is their work on variable compression ratio pistons which were eventually implemented in the "multifuel" platform combined with aluminum heads and an aftercooler. This engine made 350 horsepower at 2800 rpm and 710...

The bearing assembly looks very much like that for the tractor water pump. You can get a kit without the tractor impeller from amazon: https://www.amazon.com/W921350-Water-Repair-Oliver-2-135/dp/B07688PFFD

There was some mention made in this forum about the tractor version of the multifuel having a check valve to prevent the oil cooler and filters from draining out into the pan. Fast forward to 1:45 here to see how it is done: It looks like we would have to add a counterbore and tractor engine...

I replaced the 6 point rod bolts in an engine with the more modern 12 point and found that there is quite a wide variation in rod bolt torque specifications: TM9-2815-204-35 (LDS427-2): 800 lb*in, 66.67 lb*ft Troubleshooting the LDS465-1 Manual (1968): 1200 lb*in, 100 lb*ft Hercules Svc Manual...

At one point, I had the force calculated from the bore and power steering pressure but I am not able to find it. I think that the requirement is 8" for full travel. The threads on the end of the slave cylinder are 0.875 -18NF and the rod end that I used was a Ford D8NN3B539AB which is...

Many have posted difficulty with their alternator overcharging and attributed this to the regulator. I encountered this recently (on alternator after alternator) and discovered that the fault was not with the alternator/ regulator. This alternator uses the excite wire as the voltage sense...

The OEMs who used a lower compression version of the multifuel in tractors blocked off the oil passages in the block/ head and ran external oil lines to the head. Presumably to address the persistent oil leaks. Suggests that this cannot be totally eliminated unless you do the same.

There were two reasons for the custom arm: 1) The stock 5 tom steering cylinder is too long for off the shelf rod ends. 2) There are only two off the shelf rod ends that fit the threads of the steering cylinder. The smaller of which is not rated for the force capable of being exerted by the...

There have been a lot of posts indicating that the "new style" multifuel head gasket with built in fire rings is not to be re-torqued. This is inconsistent with the information in the White Motors service manual... White Motors (and Oliver) used a version of the military multifuel engine in...

The SM420 was eventually fitted with a neoprene seal to reduce leaks. Novak offers a service/ kit to add one to the earlier versions. https://www.novak-adapt.com/catalog/transmission/transmission-parts/sm420-parts/
