I've double checked everything and done it by the book. I have heard how well they hold, but have also seen a few post here that say their parking brake won't hold adjusted either. and I understand how much faster a driveline brake spins, which is why I would do mechanical, so there is no...

I am looking for some input on a secondary driveline/parking brake. there have been a couple times my parking brake has not held, even though I routinely check and adjust. most of the time it is when I have a load and have to park it on more then a 5% grade. I thought about a pinion...

waste gate is built into the turbine housing, so definitely NOT a GM-8. GM-6 was the center mount turbo used in vans, so my above post was incorrect, the GM-4 was used 94-96, gm-1 and gm-3 were used 92-94(years overlap for small design differences) I'm willing to bet you have the GM-4 turbo...

Can you remove the heatshield and take a pic of the waste gate lever? '96 was an odd year, most seem to have the gm-8 but I have seen a few with gm-4 Sent from my iPhone using Tapatalk

Looks good, where did you get your dash?

I just realized I never updated on the brake fluid being low, but found no leaking axle seals or any leaking lines, and no wheel cylinders were leaking. my airpac has the plug in the rear, so I removed that, but saw nothing. the fluid was low before parking for winter, it had dropped a couple...

I have two more gaskets, well maybe one definitely, for the valve cover, but now that you say it could be bent, that could be a more likely scenario, I noticed Memphis has some NOS ones for 60 bucks, may get one as a spare. I had noticed some rust last time I had it off, so even if I get an...

April is winding down, last week, so I pulled the girl out of hibernation, going through everything. Couple things I noticed, I'm a little low on brake fluid, but have yet to discover any leaks on the lines or at the wheel cylinders(still have 2 to look at) last place to check is my air pack...

Not threaded, it is tapered, a pitman arm puller works sometimes, or even any 2 arm puller sometimes. Sent from my iPhone using Tapatalk

It could certainly be a cause, there is a lot of force being spent when lugging an engine, and it is all being transferred to the crank. Sent from my iPhone using Tapatalk

I would say, now that we know the damage, is that the car hit the truck so hard it hit the curb with the outside of the tires, the middle axle was able to jump the curb because of the chock, this pit the extra stress on the dog bones and spring packs, because one axle was pressed against the...

You might have a gm3 or gm4 turbo, both had mechanical(spring) actuated waste gate controllers, any turbo that came with the electronic injection pump used a vacuum pot to control the waste gate, no vacuum no boost, his being a 97 had the vacuum pot. I took mine(97 engine, gm8 turbo) and cut...

If you run ECU and electronic injection pump, otherwise you need to build or by a "TurboMaster"

Wait! It could be brake fluid, and if it is, it could mean no brakes, double check brake fluid level carefully, if one wheel cylinder fails, you'll have no brakes. Sent from my iPhone using Tapatalk

700r4 has 27 spline output shaft, TH400 has 32 spline output, so transfer cases are not swappable, also 700r4 is about 1 inch shorter then TH400 I am unaware of any differences in the spacer/adapter Sent from my iPhone using Tapatalk

Vacuum pump was used to control boost and emissions if present, nothing else Sent from my iPhone using Tapatalk

Well, found my parts book, but no FSN in them, just Part #'s which I haven't been able to cross reference yet. Now I thought the multi-fuel cables were shorter, so that's why I was hesitant to purchase one online, cause I originally saw those on Ebay Now I also found another cable, NSN...

Thanks, looking up that NSN, looks like a 52.750 to 53.250 length, 3 inch travel distance

Hi all, looking for the part number/and or total length for the locking Hand Throttle Cable for the OA331 gas motor, I managed to misplace my parts book, and the end of the cable that broke-so unable to get full length. My brother has access to Mack truck parts, and we think we may be able to...

Well if the flex plate is straight, uncracked, and bolted tight, it really doesn't leave room for much else. Worse case scenario the crank broke because the Harmonic balancer is bad
