Blown 7's ultra secret timing cover/oil pump

jeepsr4ever

Stage one! Designing the base plate

The baseplate of B7's T-cover is made out of billet aluminum and is 1.25" thick and 12"s wide and 17"s long. Its a nice slab of aluminum. Here we can see stage one of the build and the extra arm is for supporting a chain driven dry sump oil pump that will live near the oil pan on his super charged 401. You can see the extra bolt holes for the chain cover and the counterbored retaining bolts for the baseplate to cover plate. the stock oiling holes have been blocked off in this application.

More updates soon!

Watching as a piece of ultra trick coolness is developed, is also very cool.. keep it up and you guys will be famous..(ok just promise me that if you get a tv show like Jesse James... you put the @#$%$$#@ hat on right!!)

ok, that's what i was thinking..."Why the hell is Bulltear adapting a crank-driven chainsaw? :-| 111!!! :?:

Thats going to be one mighty fine timing cover. Can i get one with the sawzall adapter option? :?:

Dusty

will that be an issue with the alternator? :shock: do it right you could rig that cover like a cummins and have the powersteering pump become gear driven :lo1l:

Why stop there? Heck, make the waterpump, alt, ps, and OBA all gear driven. That would be one complicated timing cover and gearset. :-| :!:

Hey Dusty....not to hijack this thread....but do you ever make it back up to Missoula ever? I was born and raised in the bitterroot, left there last year and miss it something fierce. :smile: :razz:

I miss it everytime i see a picture or an article or talk to a family member. i'll be back some day but my spot is down here for now.

I make it back at least one or two times a year. :!:

Got a wedding on the 15th i have to go back for

This is the final drawing of the backplate. Jeff I will post up a couple pics of the machine work and maybe a quick video of a end mill going to town in the next couple of days here.

Just a couple of linear tolerances to keep in mind

When I was a yonger man and had to crank handles for a livin' I had to do that stuff in my head lol........

tarior

Is it done yet? :mrgreen:

Lots of pics here so bear with me as I try to explain the first stages ok. This is a 3 piece timing cover that will utilize the use of the Morroso 3 stage dry sump pump and free up the distributor gear from having to drive the oil pump. Pics in 3 hours

Here is the first block to be machined. It is approximately 12"s by 17"s and is 1.25" thick. A spendy piece of aluminum :idea: Chucked a sharpie into the spindle and let the machine draw the outline of the part of the aluminum. Piccasso :?: The inside line the the exact path of a 2 flute 3/4" endmill spinning at 5200rpm and 27 inches per minute.

Time to pop some holes

Milling out the cavity for gear and chain clearance

Roughing out the cavity for the dry sump chain

Cavity all clear

Milled down extra stock for a 1.2500 thickness and a flat surface.

Holes tapped and the precision dry sump hole reamed out

RE_FIXTURE..If you look closely you will see the oil control grooves for a no leak condition on a soft gasket. This is the finale staging for the profile on the base plate. From here is will get a counterbore in the back and be flipped over for oil pan seal and tapped holes for the two front pan bolts.

Thats all for now...I know its just a tease but the best I am saving for next.
