Wauk "V" Question For MRXLH

[Bud Tierney]

As you seem to be quite knowledgeable re' Wauks, can I pick your brain on this one???
My older parts catalogs list a Wauk "V" 4cyl, showing up in a 1929 piston catalog as a 4" bore and in a 1930 McCord catalog as both a 4x5 and a 41/4x5.
In looking up 145's in a 94 Clevite catalog re' the 145GZ bearing question posted, I noticed that that catalog shows a 6cyl "V" 41/2 x 51/4 (not VRD/VRG or V-anything, just plain "V") taking the same bearings as the 145's listed.
A 1966 bearing catalog lists both the 4cyl and the 6cyl "V", taking different bearings, so I assume the 6cyl was NOT a development of the 4cyl??
I hadn't noticed Wauk duplicating engine designations before; is this just an oddity, or did they do it occasionally??
Many thxx for any clarification!! Bud

I will do a little poking around and see what I can come up with. My first response to this is off the cuff, but very common with any Waukesha series engine. The difference is more than likely the crankshaft/bearing changes that have seemed to plague Waukesha throughout their history. For example the VHP was introduced in 1966 and is still produced today. There are like 7 or eight different crankshaft/bearing combinations that can be used. Likely this is the case here. Good news is that after the Wauk factory class that I am in this week, I will get a subscription to WED link that might have alot of answers for questions like yours.

Looking in my application book, the 135GK has that bore and stroke arrangment, the latest I go back is to the VC series.

Went back thru my parts catalogs that include engine lists, to see if I'd missed the 6cyl "V" before, and came up with more understandable info:
The 4cyl "V" isn't in a 1917 ring catalog, but shows up in 1929-30 piston and gasket catalogs.
All the various "V's" show as fours up into 44/45 catalogs.
I don't have anything reliable from 44/45 until a 1966 Thompson bearings catalog, which omits the 4cyl "V" and includes the 6cyl "V", listing it as just "V" and not as 6V, as with most other Wauk 6's of the period.
It's a 1968 Am'cn Hamm'rd bearing catalog that lists both the 4cyl "V", as "early", and the 6cyl "V" as "late", which would appear to indicate the engine was enlarged to 6cyl's under the same "V" designation.
Don't waste any more time on this; I'll drop an email to the Hist'cl Soc during the week-they'll probably remember what happened.
I don't have anything on "VC"; I assume it's more modern than my stuff, which is mostly before 80's.
Many thxx for the time and effort. Bud

Bud, the V doesn't stand for "V" configuration, it is just one of the letter designations. Case in point there is a inline 6 which is a VHP series engine. VHP supposedly stood for very high power. As I was told the VR stood for very reliable and VRG stood for very reliable gas. Most of the people who would know this have long since passed and the current staff at Waukesha will tell you engine series letter designations don't mean anything.

I am showing a V80 and a V85 as well as a V122 and a V125 as available parts manuals These were climax engines. With the V80/85 probably being the 4 cyl and the V122/125 being the 6 cyl.
