you forgot to mention the shifter linkage

If the brinn bleeds like my bert does it's pretty simple. Just crack open the bleeder on the tranny and let it gravity feed for about an hour.

You might want to lube the input shaft. Some guys lube and some don't. I use a dry graphite on mine. Also, spend the extra money and use a long 6" yoke. This will allow enough travel without taking out the tailhousing seal. I require one because I'm using a 4 link suspension, but the 2/3 link won't move near as much.

i would reccomend lubing the shaft, we usually coat it real good wwith antiseize, just to help keep it from sticking. Makes it easier coming apart.
Other than that, bolt it up, connect your clutch line, shifter and fill it with oil. Then go racing.

Yep, its that simple, I thought the cost was too much but after getting one, the simplicity makes up for anything else.

i run a bert in my latemodel but i assume they are similar.
we use redline racing synthetic atf fluid & change about halfway through our racing season.
as long as you only use the clutch when you need to and make sure you have it fully depressed when the car is rolling you should have no problems. i have found it easiest to shift into direct drive at around 4000-5000rpm.
we had a heap of problem bleeding the clutch, but in the end we just used a "mighty vac" vaccuum pump & had no problem.
the other way we have done it is, jack the back of the car up so the bleed nipple is highest, but don't pump the peddle, just depress once, release & bleed.
i bought my bert 2nd hand and am still using it 12 months later hassle free.

use atf fluid and change every other race, it only takes about a quart to fill up. Dont over rev it while trying to take off and once you get it going push the clutch in as hard as you can to make sure the clutchs aren't slipping. I shift mine around 3000 and some guys cant get theirs to shift till 4000+ you'll find the sweet spot after a few shifts.

The hardest habit to break is, if you spin or get spun or have to come to a stop quick the natural reaction of the left foot is to press the clutch in.............BIG NO NO! I dont think once or twice will hurt anything, because i've done it with mine and it still operates fine.

I talked with the guys at Brinn and they reccomended ATF or 20w50 engine oil. They also said not to use synthetic because it was too slick and wouldnt allow the clutches to grip right. We change ours every other race and never have problems. Tranny is 3 seasons old now and still works great. These trannies are virtually indestructible.

He's right the clutch will feel soft not like a regular pedal. You have to get use to it.. easing into the pedal instead of out of it to go. Remember you have to use the clutch in low and reverse only.... if you shift from high to low you wont go anywhere until you push in on the pedal. Oh and i forgot to mention there is no shifting on restarts. you get on the track and get in high gear and go. So if you restart at low rpms, depedning on cam and motor combo it might start to chug a little till you get up to speed. That is a drawback.

It is a mighty good idea to use a winch to get car on trailer, my pit man loaded the car twice this year and drove the car off the trailer twice. He just can't get used to the clutch. I started using the winch after the second time and that stopped it from happening anymore. I use synthetic gear oil but may change now in lite of what you pointed out. The tranny grinds a little when shifting but that is normal. they are straight cut gears.

It's important not to get the 2 confused, Bert uses type f tranny fluid and Brinn's use Dextron/GM tranny fluid or 20w50 motor oil.
Go to: masonracin.com and check out the section on Bert tranny's, it'll tell you everything you need to know about using a Bert or a Brinn.

DO use anti sieze on the input shaft!!! I spent 2 hours in the claim are this weekend. 45min to pull the motor, and 1 hr&15min to get the freaking coupler off of the input shaft.

Also, DO NOT burn out in first gear. It is for nothing else but getting rolling. No dry hops, or cushion checks otherwise you'll burn that little clutch up fast.

We have been running one all year. we change the fluid, ATF, every week and lube the shaft. we also grease the shaft every week as well. We have also used the 6" yolk on ours all year. we have had no issues with ours at all. we are getting ready to end the year and are looking at doing a "freshen up" on it now to keep it in good shape.
