Thanks for you help, the 2oq sounds like a mack part number

Thank you for replies , It is a work truck but maybe a 1000 miles a year

I have it filled with grease but it keeps working out of input shaft

only numbers i can find are 56955762 which seems like a saginaw number

the other number is 2OQCA512

both in casting

I really appreciate your help

thank You

always worried about Ct MVD  seeing it leaking

Hi

I was hoping someone could help me identify the steering box in this truck

It is a manual box , Mack has no info and camerata truck parts  cant figure out what it is

I was hoping to get a seal kit for it, It is fine except for leak in input shaft

Any help would be greatly appreciated Thanks

Ok thanks will Try there

Hi

I need some help. I cant seem to find anything on internet or from mack

I have a 70 U model, with a thermodyne,at least that is what valve cover says.

Purchased truck in 83, we did an in frame overhaul on engine in 2004. All parts available from Mack then

Was running perfectly, but it knocked out a wrist pin bushing, about 25,000 miles since in-frame.

It has a 1-5/8" wrist pin, I don't seem to be able to find these wrist pins or bushings. Mack is no go and PAI also does not show them.

I'm a little confused , i thought all Mack turbocharged  diesels had 2" pins. Wondered if these parts were still available. This engine does not have wrist pin oil nozzle coolers.

Any help would be greatly appreciated. The motor is perfect except for wrist pins, hate to change if we don't have to

Thanks again

it is a Kysor 934029?

The evaporater and heater core 

Come with it

How much do you want for it?

i know this was posted a long time ago, is any of this for sale?

I had a switch in my cab

couple years back Ct DMV stopped me , they wrote me up for it , it was a big deal

had to run the truck through an emission test with it connected so they didnt pull the registration

I ended up shimming the valve to get as much as possoble and staying under legal limit for opacity

Thanky you I will give it a try

Need a speedometer angle drive for my 70 U model

It has a quad box I beleive for transmission

Have not had any luck on finding angle drive from anyone near me

Can not get one from Gabrielli the dealer tells me

My 70 U model had an air starter for years, large air tank on rt side for supply.

a relay valve right under the pyrometer to start truck

Got tired of it about five years ago and installed electric starter,

It was an ingersol rand starter also

Truck was fitted with a governer bypass valve from factory, will put about 150 psi in tank for more starting air

Is the large tank on passenger side an air tank for air starter.?

I had same looking tank on my u-model with an air starter

I guess he dont see signs that say NO THRU TRUCKS and then 2 more that say NO TRUCK ACCESS and then a few more that say NO THRU TRUCKS. Theres a drop off down the road, one of the worst roads in CT

will do

Thanks for all the Help

The vin # is u611t1719

All the parts I have found in the places in Ct have an a on the end of the part #

I think this front axle was a lighter version being it was a tractor

However it lasted all these years and we broke it.

The truck was buried in mud and we were pulling it with excavator from that side , We noticed it was broken right after that

Try and get the picture of truck on today

Hi Rob

I am looking for a right front front spring hanger for the u Model

Part #53qk567 RH

I am in Ct.

I have been searching and not finding the part

I picked up a hanger with correct # with an A on the end, but the spring eylet relation to the front crossmember is different

It Bolts in no problem but the right side of truck sits about 1.5" too high

I have thought about changing the left hanger to match, Not sure if that is crazy or not

Any help would be appreciated

thanks
