Herb is right on what he told you .I worked for mack in the 60s and i remember those days good just cant remember what i did this moring.I always used 32 qts if filter was on the block and if on frame add another qt. The way to check your stick calibrtation is drain pan and add 16 qts to dry pan and make low mark and add 4 more qts and make hi mark then when that is done dump the rest into filter top and i would always bleed the filter at the fill plug while engine is running the check. The filter # is 236gb340. If you ever have that filter can of do not revere the oil lines or you will need new engine. glenn

I saw some cement mixers in the mid 60s with the 475 scanis the first engine that i ever saw with the centifuge oil filter and that little baby mack engine 465 i guess it always whanted to be a real engine when it growed up and some of the mixers had a 3208 with allison and a 3 speed spicer behind that .I dont remember if the 465 or 475 were turboed or not. that is the last ones i have seen. glenn

That is the best way then you have no stress on the splice.There is no stress behind the trunnion stand on a mack except the weight of the tail lights.I have did this before and end up using mild stell to roll the frame reils and works good. glenn

It is ok to scratch a gear one time but not two times but if in doult about it i can tell you that all trans have magnets in them just for new driver to scratch gears. If it is a play truck you will never need to change the grease. glenn

Are you asking for a wire diagram or what? glenn

Sounds like you have a brake that has camed over and you need or i would put new shoes on both front wheels and make sure your drums are good because i have seen many front drums used that was scored bad and now they have brake problems so to me you dont take short cuts with front brakes. glenn

Go mto caterpillar and check with parts.Cat makes a epoxey that is for that purpose. glenn

Let me tell you what will hapen when you use a 13 or 15 speed behind a maxidyne.First thing is it will work but you will not like your self for doing it because i have seen it done sevral times.the last 600 or 700 RPMs in the torque range is dead on a maxidine for as the torque rise and the RPM splits in a 13 speed is around 300 RPM and maybe 500 RPM in a 15 speed so you would be riseing in toque real slow at the top RPM. A 8LL eaton would be another good trans if you dont like the 6 speed trans.A 13 or 15 speed would be ok if you would pull pump and have calibrated to a 10% to 17% torque rise like a ENDT 250 pump was set then your torque will be better at top RPM.,But you dont have that low end torque like a maxidyne. glenn

I have used some that was not that good. that flywheel is hard to come by I would grind it some but dont try to take the cracks out but enough to clean up and that is for a mack push type clutch and that is not good for much horse power like a hot end 675 or 676 unless it is 2 plate. this was common in there day because if they were not adjusted when need be they would slip and get hot. glenn

Yes you can do that first strech your frame the wheel base you want and if useing a mack set up then slide your tandem in the frame and bolt it down. glenn

I like to jack up one rear wheel and put the trans in high gear in both boxs and get some one to bump over the wheel which a little girl can do while you watch the marks and they will be on bottom of fly wheel or on latter engines on damper or if out of a f model they can be on top of flywheel glenn

If that engine came with out the air comp. try to remember to install mthe oil tube in the end of the drive shaft fore the comp. or it will not last very long. glenn

Do i get 3 trys or is this a trick question? glenn

Ya black box it very bad for engine i no use it, burn up engine if not use pryometer but use pryometer you be ok. glenn

That box you got there is the fastest was short of draining the coolant out of a engine that i know of to burn up some pistons because you are advanceing the timeing too much to kept the exhaust cool. glenn

call him up and tell him to take to rad shop and have them to recore and he will get a new core and they will use his old tanks .that is what i did to mine and you can some times get a bigger and better core. glenn

I think you are looking at what i call a sluge vavle or purge vavle or spitter vavle and it sees water and spits but dont have a signal line and in my eyes ant too good. glenn

now i have enough info to tell you how it will coast if you do it 50.00 dollars per alxe and if shop does it 75.00 dollars so juat be safe bring about 110.00dollars and tell mthe man your are in ahurry and maybe he will save you some time. glenn

I whent to the other web site that you posted and i don see any reason to go back to it again because there is no reason to have to read dirty talk like that is left there. there is better ways of conmucating than that.but to tell you the cost to do a brake job tell us what it is and how old and what kind of brakes is it stopmaster or cam brakes and is out board or inboard and how many axles. is it air brakes?The age of truck does not mean that the brakes are bad . glenn

The reason you dont whant to tow with both in netural is same as any manual trans the main shaft is turning because the rear yoke is on that shaft and the main gears can not turn because they are in mesh with the counter shaft and it cant turn because it is mesh with the input gear and input shaft and it is in the clutch and it is not turning so if you have been towed very far it can burn up the bushing in the main gears on the main shaft of a single counter shaft trans and on a 2 counter shaft trans you will burn the thrust up and the gears on the main shaft . The reason is because they cant get no grease up on them because the counter shaft gears are not turning and the grease in not high enough to get to the main shaft ,I have seen alot of trans burnt up from a new tow truck driver that did not know that .I seen one pulled from okc to tulsa which is 100 miles and the drive line still hooked up and the driver towed it to me and i showed it to him and told him to feel of it and he said i can feel it from here it is hot.You could spit on it and it who spit back at you. glenn

Here is the road speed calulator look on right side for the road speed calulator glenn http://www.roadranger.com/Roadranger/index.htm

Pump only pumps when engine is runing and that trans will wear the bushing out real fast on the main shaft geares. Them gears are hard to come by.I have towed my truck when at idle . glenn

the meritor trans may be eletric instead of air on the range now if it is get under there and see if air is coming out of the trans, breather and if so you know where it is now but if so you should have a shifting problem. glenn
