During performance of normal periodic maintenance, the mechanic found a small water leak at the bottom of the nine year old port stainless steel riser. While removing the riser, he broke off all four rusted bolts that connect it to the turbo. The turbo is currently at a machine shop that is trying to remove the sheared studs. I am hoping for the best but in anticipation of the worst, where could I find a replacement turbo? I called North Harbor Diesel but they only had one for a 150. Is there a difference between the 150 and the 135 turbo's? Thanks for the help.

I think they are the same. Any decent machine shop should be able to remove broken studs. Next time use penetrating oil before attempting to remove nuts (20-20 hind sight)

Pretty sure the 135's are just oil cooled and the 150's are oil and water cooled.
Even if the machine shop can't get the studs out, they should be able to drill, tap and timesert the holes for you.Even if they have to weld up a big hole and redrill the holes it's likely cheaper then new housings.

Bill, the mechanic at Hawleys removed the riser and I have to assume that he used penetrating oil. I would have. rmacdonald, I did talk to a parts guy at NHD, not sure if it was Bill, and he said that the part numbers were different between the 135 and the 150 but he only had the 150 in stock. Stray Cat, subsequent to my post, I did some additional research and I believe that you are correct, the 150 is water cooled and the 135 is not.
You are all correct in that a machine shop should be able to fix it but I just have not found a machine shop that can do the work in less than three weeks due to work load. I was supposed to head north two days ago.:sorrow: Thanks for the inputs

I have a 1987 135 hp hino and my turbos are diffently oil lubed and water cooled
I did replace my port turbo and I believe This is a 150hp unit. The turbo housing is bigger. I remember that on the old turbo the hardware were studs for mounting.*
on the new turbo one of the holes were threaded so I had to remove one of the studs and drill to make this a clearance hole to allow me to put a bolt in from the back side. Make sure to use antiseeze on the threads. I think I bought the turbo from API or some thing like that over on the west coast. Paperwork on the boat.
I also changed all my water coolant lines and fitting on my turbo. Stock was 3/8" or the metric equivalent. I installed 18 or 19mm (cant remember) fiittings to number 10 AN fittings which is 5/8.
I changed all my coolant lines on my turbo to silicon with heat shields.*
I drilled and resised The fitting comming out of the block where the coolant line feed the turbo. I believe this fitting was a 1/4 " or*metric equivalent I change this to 3/8 NPT to 10AN

Anyone else modify their turbo coolant lines to bigger ones. Earl says that is the difference between a 135hp and 150hp Hino. More coolant flow to turbos=more HP

Maybe yours have been switched out? Difference in model years in the 135's? Steve3218 has an '87 w/135's and his are only oil cooled.

Bill, I do not know if mine are the original turbos but the bearings on mine appear to have oil flowing thru them.

They all have oil flowing through the bearings thats why you should always let the turbos spin down for at least 5 min. after they have been spun up
