Does anybody have experience with the ARP head stud kit for 1HDT? I have been searching everywhere but I couldn't find any info on this. Little bit of background info.. I’m looking to do the head gasket on my 1HDT as a preventive maintenance. The cruiser has 320K KM on it and recently I...

Any update on this? Situation is identical...I left it as is since it was working for the past 100K, but I would like to understand the implications..

The surface around the oil seal looked dry when I took the cover off. Actually the whole cover looked dry...

I'm doing the timing belt/water pump maintenance and I have noticed some oil leak right on top/above the water pump. I did have small wet area under the valve cover (gasket to be replaced now) but I can't really trace the leak down to the water pump area to explain what I'm seeing. Everything...

I did a bit more reading, and if I understand it right option 1 is used with disc brakes and option 2 is used with drum brakes. The hub side seals will differ too. Disc brake version will use seal 90311-62002 on the hub side and there is no backing plate seal. Drum brake version will use the...

Thanks! Now you have got me thinking...the RH backing plate has that rounded lip in the middle (similar to the pic Malahki has posted above) and I thought that is serving as the seal/seal cover. I don't think 90313-93001 can fit in there, and I certainly didn't have it before. That makes me...

Hi, I'm in the process of changing the rear backing plates on my 1991 HDJ81. I have ordered 46504-60050 (LH) and 46503-60050 (RH). Funny enough the RH side came with the oil seal + mounting bolts whereas the LH is missing it. Both are OEM. Can anybody help me out with the part number for the oil...

Thank you for sharing this! After some research I have found a pretty good article about the pros and cons of timing adjustments. They pretty much say what you just said. Adjusting Diesel Engine Injection Timing My pump is custom tuned with custom pin so I'm sure it's outside the factory...

FSM asks for a dial indicator to measure the plunger stroke for the IP, which I don’t have…is there a rule of thumb when it comes to this? I had to replace the intake manifold gaskets and since all the fuel lines were out I figured I try to advance the IP timing (tilting the IP towards the...

Thanks! What a relief! My heart rate went to the roof when I have heard that grinding noise...

Sounds logical. Would this apply to a part-time transfer case too? I don't think there is a centre diff in a part-time system. Is there?

If I'm stationary and in neutral there is no noise, only when in gear and rolling without the Hubs locked. Am I understanding it right that what I'm experiencing is expected (normal synchro behaviour), I should just be careful not to engage the 4wd without the hubs locked while rolling to avoid...

Can anybody test/tell me if what I’m experiencing below is normal for my 5speed HDJ81 with the part time HF1A transfer case. When I’m engaging 4WD (electric switch on dash) without the Hubs locked there is a loud grinding noise coming from the transfer case. Lasts roughly 2 seconds then it’s...

Does anybody know what is the flywheel thickness tolerance for 1hdt? I'm looking to resurface the flywheel but the local shop never dealt with this flywheel before (no surprise )...a reputable shop in BC who worked on these before would be also useful. Thanks
