Early R400 could be had with a Chrysler 413. Is that what you are thinking of? 414 was a IH farm and industrial 6cyl. diesel. Chuck

Hi folks, I spent a good part of the day looking over my parts and parts trucks for enough rod ends and ball studs for my current project. But I may come up short for the next one. I have to imagine with all the trucks, tractors, and other equipment out there that use this style rod end there still must be a source for them. It seems there are plenty for the pickups and vintage cars. Any ideas or sources? Chuck

Hi Folks, I finally got the pictures I promised. You can find them in my album B61S ready to work. I hauled a load of scrap with it this past Saturday. All went very well. Folks at the fuel stop and the scrap yard seemed to really enjoy seeing it. Several people wanted to talk about it. Boy that makes ya feel kinda good! This week it will be a much heavier load I'm hoping for near 20 tons. That will be a better test of it's performance. Chuck

Finally after 10 months in the barn my B61 has been converted to a truck tractor. I'm now working on the last items on the punch list but I did get to take it for a ride pulling my dump trailer. It felt good and I'm very happy I spent the time and money to convert the air system to a primary and secondary system like newer trucks with relay valves. Now the brake timing is perfect for pulling a newer trailer also spring brakes on all four rears makes you feel confident. The power isn't much but I guess thats what the quad box is for. Having working gauges is also a plus and even with a 7.00 rear ratio 50+ MPH on a secondary road was no problem (untill you hit a hill). I'll try to post some pictures soon. Chuck

The loose wedges and a drive around the yard will probably loosen them. Then the next problem willl be the spacer. A good air hammer with a flat hammer on the spoke may help. Then when the spacer is off I like to go over every spoke with my needle scaler. That really cleans the spokes nice. The hopefully if the inner wheel is broken free it will slide right off. Good luck. Chuck

Well I guess I'm not the only one looking for this stuff. I do have some old Mack part mumbers for the welting on the B models I'll check into that. I also went to a local industial supply that specializes in power transmission belts. They seem to have many different options. They are going to check price and availibility for me (the right guy was on vacation). I'll let you folks know what I find out. Chuck

Hi folks, I was wondering what to use for insulating my fuel tanks and brackets. Very little is left of the old stuff and tanks are starting to move around. Also what about the straps what should I use there. Thanks Chuck

Hi folks, Have any of you changed windshields in a CH? It doesn't have a key strip in the gasket. Any suggestions? Do both have to be done at the same time? I've done smaller one piece ones with this type of gasket by wrapping the gasket channel with wire. But this one seems to be a bit large and awkward for this technique. Thanks for any help. Chuck

The torque on the U-bolts is 1400 ft-lbs. and shouldn't be less on a hard working truck. Chuck

Just a couple things to add to what Herb said. The retainer looks like the early factory type. The 3/4" rod goes thru to the other side. If the truck isn't going to work hard consider trying to save the U-bolts. They cost arount $180 for the set. Use only new if it is a working truck. Then the bushings come in several different lenghts. Bring the saddle to a good spring shop and they should be able to suppy the correct ones. There are also two spacers inner and outer they need to be checked for wear as well as the saddle where they contact on hard turns. And lastly the spring needs to fit the saddle with little to no side clearance. Many of these wear points need to addressed in relation to how the truck will be used. Don't take shortcuts on a hard working truck or it may dissapoint you. Chuck

Hi Folks, After talking with Speed about the trucks I've done with hydraulic brakes I remembered they have a web site. So far I built one complete and one cab chassis only for this customer. These trucks are busy all the time sometimes doing two parties each per day. I closed my business over two years ago but still keep in touch with this guy. I was just there to help him with a couple minor problems last week. Since I built the trucks what may be difficult for others is easy for me. Hope you enjoy. www.biggreentruckpizza.com Chuck

Hi Speed, I've never worked on Mack hydraulic brakes but I've worked on others of that vintage. Often the rust will build up between the shoe and lining causing brake drag. The adjusters are generally in two groups, Major and Minor. Major adjusment is for initial set up then minor is for maintenance. One that I have worked on is the Wagner Hi-Tork. That type has five adjusters per wheel and you set the shoe clearance to the drum with a feeler gauge through the backing plate. I have many of the old Motor manuals that cover these early brakes if you need info. As for master and wheel cylinders. My persomal preference is to send them out to be bored and sleeved with brass. I've done a couple trucks that way and it works well. You never have to worry about corrosion in the cyls again. I have the name and number of the shop I used if you need it. The ones I did were 46 and 47 IH KB5. I did these two trucks for a customer who uses them for his catering business. These trucks run nearly every day and with all the equipment weigh in about 15,000. The first one I did actually made it into Wheels Of Time in a feature article. Send me a email if you need any more info. Chuck

The interior is pretty basic, no padded door panels. The headliner and dash look OK but dirty not sure about the back panel. Let me know what you need I also have other junk cabs. I'm in Hamden CT. Feel free to call. 203-641-4419 Chuck

Hi Rob, This R700 is a 78. It's mostly complete only a few pieces have been picked from it, like the grill and headlight bezels. Let me know what you need and I will try to help you with it. You can feel free to give a call if you like 203-641-4419 Chuck

I've got a 866 V8 in a R700 and with the turbo on the back it takes up all the space provided by the longer hood. The R 700 is a parts truck I just brought in so I don't know much about it but I could take measurments . Or even put it side by side with my 1966 R609. Chuck

You may want to check with Mack. There have been some updates required for that trans. Not too long ago I did one for a customer that had a similar problem with a 18 speed in a CL700. There were changes to the range shift clutch pack and the air cyl. Mack will need your vin number and maybe the 11KBA number from the trans. Chuck

I've dealt with a few stuck plungers lately. If you pull the side cover and see one of the springs compressed and not touching the lifter that could stick your rack. I usually put a screwdriver between the coils and ligtly tap down with a hammer. I've had good success with Mack pumps that way. Didn't have good luck with a pump on a Deutz as soom as I touched it with the hammer the plumger broke and the spring snapped open. That pump turned out to be beyond help though heavy corrosion everywhere. The big thing here though is patience. Like Herb said take some time use plenty of pentrant and be sure things work smooth without sticking especially the shutdown. Chuck

The cast trunnion A frames do often crack near the tube. They do take a weld very well if you clean them up stop drill the crack and vee it for the weld. Best way is to remove them to do this. Chuck
