Again, cavitation erosion is caused by cylinder liner vibration. The coolant additives create a film around the liner to protect it. I would suspect that there two reasons it is needed on diesels. If the liners are steel, they are more susceptible to erosion that cast iron. Turbocharged...

Cavitation erosion is similar to ultrasonic cleaning in that the cylinder wall vibrates causing the coolant to vaporize into microbubbles. When the cylinder wall moves away from the coolant, the pressure is reduced enough tor the coolant to vaporize. These bubbles inplode on the surface of the...

I am not trying to rain on your parade but I had considered a similar thing in the past. The problem with the gmc M135/M211 is that the low range is in the transmission, not the transfer case. You will be pretty short on gear reduction with the C6. You can retrofit a dual range transfer case...

All of the diesel oils that I have seen are rated for spark (S) or compression (C) ignition engines. There was a recent article in Hot Rod magazine which stated that the diesel oils are better for older engines since they have more of the antiwear additives (ie zinc, etc). I wouldn't use...

Carguy, Do a search on ebay for this number 4645609638. It is a new VDO 24V, electronic 3krpm tach for $9.99. I can send you the instructions for hookup. It also has an hour meter. You would probably want to buy a cup for mounting. It is a nice tach but looks out of place in a deuce...

The deuce tachs on ebay go to 3500 rpm which is plenty. As far as I know, the only issue regarding the mechanical tachs is whether they are 1/2 or at crank speed. I got a tach drive, civvy distributor, and a full flow filter/ oil cooler for $20 from an OH200 at a "local" salvage yard. These...

I would like to add a tach to my '53 M35. I have a tach drive for the gas engine (driven at 1/2 crank speed). Are the multifuel tachs designed for 1/2 engine speed? Does the tach use a 0.104" square drive like most speedometers? I am assuming that the whole dash and gauge panel needs to be...

Took awhile to find the numbers: Fed # 51204736511 Tech Ord # 7078072

Anyone have or know where I can get one of the curved head bolt wrenchs for the R6602 5-ton gas engine? It is like the one for the multifuels but for a 3/4" head bolt.

BFR said it right. No amount of marketing is going to break the laws of physics. I'll believe it when he gets published in a peer-reviewed journal...

Simply increasing jet size and/or advancing timing won't likely gain you anything. There is only so much you can do with low compression and low rpm.

The front case containing the sprag unit can be removed with the transfer case in the truck. There are two sets of sprag clutches; one for forward, one for reverse. The forward sprag will be worn much more than the reverse. It will be obvious when you take it apart. The procedures are well...

Robert, I don't have a multifuel. I had been thinking about swapping one in but have been a little leary after learning of the problems with the multifuel. I have heard about many of the failure mechanisms but I have not had a good explanation of why the multifuel does not last as long as the...

A ~$1k turbo seems like a lot of money to spend on an engine which appears to be ill equipped for anything but minimal additional power. For another ~1k on top of the turbo swap cost, you could swap in a cummins or DT466????

There was a DT466 powered tractor puller here a few summers ago. I don't remember which class it was in but it competed against allisons, rolls royces, and supercharged BBCs. I believe that it won its class...

I second the remark that it is good business practice to ship with insurance and a means of tracking package. My opinion is that a seller's responsibility ends ONLY when the package is received by the customer, not when the seller drops it in the mail.

I am assuming that the multfuel has full flow oil filtering... Most Ford and chrysler spin on oil filters have a bypass valve to allow oil to be diverted around the filter due to either the filter plugging or the oil being too cold (GM has 'em in the block). This is VERY important. Another...

This is really just a feeler to gauge interest. While I haven't put together costing yet, i expect that it will be less expensive than the current offerings from other suppliers. Will 5 amps serve most people? This should be enough to operate most small radios, cell phone chargers, CBs, etc...

I working on a 24V to 12V 5A DC-DC convertor and would like to know if there is any market/interest on this group. It will accecpt an input of 5 to 32V and output a regulated 12V.

Well, I am not going to mess with the multifuel. 30-50k is pretty miserable... From what I've read on this forum, there appear to be fundamental design flaws. I'm either going to stick with the reo gas engine or search out a cummins.
