We have family in the Tyler Texas area and I'm looking for recommendations for a place to periodically stay with our 37 foot pusher. We don't need hookups (lithium batteries) and in fact, enjoy dry camping in cooler weather. Any recommendations wit...
This might belong in Tech but since most of these engines are in motorhomes, I posted it here. If the moderators feel it should be moved, feel free....I have a Cat 3126B in my '98 Ultrasport. Recently, I had my 4th IAPV failure in 145,000 miles. W...
Leaving Baton Rouge a few days ago with my '98 Ultrasport with 140K on the odometer, my Allison 3060 decided to go to neutral and didn't want to move the coach. Thanks to the wonders of the smart phone, I found I was only about 4 miles from "Baton R...
I have a '98 motorhome with a 3126B Cat in it. The turbo downpipe that goes from the turbo to the exhaust brake has a hole in it and I am having a heck of a time finding one. Any ideas on where to get one or have one made? It's a 4 inch pipe with ...
Thanks for the replies. Tyler State Park is very nice (been there) but I was more hoping for someone that might have a private "parking spot" they would like to rent from time to time and we might make a new friend! I have two sites at my home that...
I change my oil every 6000 miles or once a year, whichever comes first. I have had one valve that lasted about 80,000 miles. If I had to guess, I would guess the one that lasted longer had a LITTLE more clearance on the piston and/or the transfer r...
Here's an UPDATE:I was in Tucson (MAN is it HOT there!!) and while there, I replaced the new IAPV I had installed earlier with one of the valves I disassembled and cleaned. The engine ran perfectly all the way home which was a little over 1000 miles...
The valve is located on the rear of the HEUI pump which is mounted about mid height of the block, on the side opposite the intake/exhaust manifolds. The pump is toward the front of the engine which is toward the back of the coach in a pusher. It wi...
Yes Fred. The IAPV is the Injection Actuation Pressure Valve and you have the operation correct. It has been a bit of a problem for many 3126B engine owners. I have replaced 4 on my unit in ~145,000 miles. When it fails, either the engine will be...
