So whilst dismantling the 5th gear assembly of the H55F, the sleeve slid off and the 3 keys and 2 springs popped out. Now I think I've put it back together correctly. So the sleeve can move back and forth over the synchro and keys aligned the the gear. Circled in red is what I'm talking about...

Yeah, I've been getting support from Dave. Will just order the one side and fabricate the other

Been busy stripping the gearbox and transfer down. It seems pretty good, but I know it was whining a little in 5th. I understand that 5th in these H55F's are a bit weak anyway. Otherwise it looks pretty good and bearings quite sound. I'll do some measurements and see if anything needs replacing.

Ok, so I've been spending what spare 'truck time' I have in staging the engine to gearbox and mounting in the engine bay. I need to cut off the old 3B Engine brackets and weld replacements in that align with the 1HDT position. These new engine brackets are like hens teeth. In fact you can only...

That's a different part number. Do you know if it's compatible?

Hey, I've trying to hunt down those brackets: 51421-60140 and 51422-60140 Looks like you cannot get the 51422-60140 anymore, so what would your thoughts be on using two 51421-60140? Not sure how different each of them are to each other. Cheers

Hello, where did you purchase these from? I'm having trouble finding the 51422-60140 so I can fit my 1HDT to a BJ73

Hello, hey just a question on the engine mounting brackets, the ones welded to the frame. Did they fit and bolt up ok? There are so many variants between the HZJ7x, HDJ81 that have the 1HDT or 1HZ engines. Cheers BRACKET SUB-ASSY, ENGINE FRONT MOUNTING, RH51421601401 BRACKET SUB-ASSY...

For my records, been doing some measuring of old to new.... The clutch pressure plate is pretty big. I don't have really accurate measuring tools, so gave some tolerance here and there.

There is probably a solution out there. This was also interesting... 1HZ injection pump signal to BJ70 tachometer sensor

One other thing I've discovered whilst examining the parts collection is that the H55 to 3B bell housing has the tachometer sensor in it. Whereas my 1HZ bellhousing has no mounting point for such a sensor. Don't even know if it would work anyway as it's a different flywheel. So will need to look...

Do you happen to know what the gap is from the front of the 1HDT to the radiator support panel? I'm not planning on moving the gearbox at all.

Yeah I could do. But it's all $$'s. Have spent enough already and will save some money for the rebuild. A spacer is something I can do for free.

Ok, well I've removed the filthy gearbox and transfer from the truck. Will give it a birthday and rebuild it. My new (2nd hand) 1HZ bellhousing arrived today and initial measurements show it to be 5-10mm shorter than the 3B one. I will clean it up, take some more measurements and see how far...
