Hi everybody... im new here. I get on everyday to look at all the stuff being talked about. We just bought a tri axle dump from buffalo ny. We started to drive it home to watertown ny and tranny went bad. tow bill home and tranny fix with a few extras was $7000. yes it was really high. since then we have put a turbo, radiator, air to air radiator, air dryer, new brakes, new brake chambers new slack adjusters, new s-cams, new tires. We finally have most of bugs out of it. Its been a real oney pit and now its working good and making us money. we bought it for $20,000 and figured about 13,000 in parts and labor. its doing great now though and hope to find some odd ball pieces to make it look better. cab is in great shape on from being up here. hope to find a grille and headliner plastic piece for radio over head. other then that a train horn has been added a few led lights. sooner or later we will put some chrome on it and it will look even better. possible winter project is rebuild rear ends and inner frame. hahaha what a joke i know. well i may ask for some help here an there like i already have a few times and i appreciate the help also. i may look for a mack r,u,dm project truck if anyone has one for sale in ny. please let me know. i love macks. My uncle just got done building a u model tandem tractor and it turned out nice. seens how the r model tractor they had someone stole and burned it in the middle of the night. we did buy a parts truck but alot of things we differnt so we sold it to a guy in buffalo. we made 1500 on it and he came and got it so i couldnt complain. I said we may rebuild rear ends this winter but if we do we may do alot more because rear ratio is 5.73 and we want to change it to a 8LL and we cant do that now because 8LL dont have overdrive to make it go fast enough. T2070a is not enough for us when we haul 22-23 ton at a time. but so far so good. nice being on here with everybody that knows alot in case i need help thanks.

thanks

Our truck does not have a Grille and i was looking for one for it. Idc if its used or whatever.. i dont even know where it mounts but to me by looking at truck it looks like it may mount onto the air to air radiator in front of the radiator. also looking for headliner for it where the radio installs above your head. any help would be great..thanks

okay thanks.. just put new compressor on cause it was letting alot of oil in system. so it may be just getting it all cleaned out i hope but will look at it again. if i replace injector pump should i replace injectors?

thanks. someone told me they were machine fit so i wasnt sure. also does anyone know why on the front of the injector pump towards radiator why puff valve leaks oil around it? thanks

dont you take that top cover off with the six bolts and tamper proof bolt to turn up or am i wrong? if thats the case how do you get tamperproof bolt out? i tried one time time but didnt know how to. also what side cover? thanks

Can anyone tell me what kind of injector pump this is? planning on replacng soon. one injector line replaced but still leaks and am afraid to tighten anymore. more info the better thanks.

looking for some parts to our 89' Mack rd690. looking for a grille for it and also the headliner piece where the radio goes in over your head. please let me know thanks A.Clement

broke fitting off manifold that goes to reversing relay. did not have fitting so i took reversing relay off and connected air line together because puff limiter is unhooked too. Can i get away without needing reversing relay? WIth puff limiter unhooked i thought it would have alot of black smoke all the time but only does when you really lug the truck. Boost gauge reads 22-28lbs most time. I dont think truck has all the power. we have replaced air to air radiator and hose to turbo and manifold, fuel filter, brand new reman turbo from D&W, new radiator, new compressor, new air dryer, new rebuilt transmission. next step is a new injector pump. Some repalced one injector line but it still leaks and cant tighten it anymore. Also read on here that injector pump rail can be moved. tried taking cover off but must be we need a special socket to take tamper proof bolt out. any ideas in how to get it out and any other ideas to get more power possibly? should i put new injectors in to when i do pump? thanks A.Clement
