1987 maxda b2600 diesel conversion part 2

Recommended Posts

1.. i have some 12v glow plugs on hand to change out the one that is fair...! putting the new one in number 1 cylinder!!

2.. old glow plug compared to the new one!!

3..going to check injection pump timing! its 12mm bolt & be very careful that one does not drop the little brass washer that is behind the darn bolt!!

4.. with the glow plugs still out... turn engine counter clockwise with the gauge screwed in to the back of the pump..turn to about a 1/4 to 1/3 from tdc until you hit a spot where the gauge no longer moves at all (dead spot)!!

5..now one can zero out the gauge at the back of the injection pump!

6..Now turn engine clockwise ever so so so slowly & watching your gauge come up, keep turning engine clockwise to 5 degrees past top dead centre..(if look real close i did not really hit exactly 5 degrees past top dead centre.... but its close enough for what i want to know)

1..the gauge has gone around once and has stopped at 10...so this injection pump is set at 1.10 mm lift a 5 degrees past top dead centre!!

2..i wrote out this info on the inside of the timing belt cover with masking tape...and on the outside of the timing belt cover i wrote the approx. mileage of when i want the the timing belt to be changed!!

3..all back together...i have seen enough evidence that this engine was looked after pretty good... :yes:

i`am not going to pull the tappet covers off to check the clearence of the valves..this would have been done recently with the new timing belt and water pump!! ( I was told this when i bought this engine...but sometimes you better check ...this 4d56t engine was in a 1993 delica & was a write off after it suffered a rear end collision,this could explain the grime around the rear engine seal {the automatic transmission took a really good hit from behind})

1..the swap of the motor mounts from the G54B gas engine to the 4d56t or 4d55t diesel is really no big deal.... except one small snag!!!... ok lets start ....one will have to thread out the motor mount nut in order to get at the bolt that holds the mount to the block on the 4d56t or 4d55t diesel !!!

2.. a quick comparison of motor mounts....on the left is the 4d56t ....on the right is the G54B gas engine motor mounts already bolted on the diesel block!!

3..the snag!!! on both 4d56t and 4d55t this darn bolt is in the way for mounting the G54B gas engine`s motor mounts to the diesel and it is on the passenger side !!

4.. take a grinder & make a notch for this to clear!!!(also it makes it a lot easier to work on this with the turbo off) :roll:

5.. swap done ...... pic of passenger side!!!

6...pic of drivers side!!! pretty easy to do!!!

just a little more info on these engines (head removal & timing belt)

1..need an exhaust down tube pipe clamp !! it has metric bolts & nobody in the country has one in stock!!!

2.. so i guess i will have to make the clamp fit from the old d50!!! the bolt spacing in pic 1 is wider then the d50`s clamp.. i have it marked in black marker some what ... & somewhat close to where the new bigger holes should go!!! I have always been taught that in order to move new holes in steel... that one should fill up the hole (weld it) & redrill it...!! but geez... one will have to be bang on for size & spacing of the new holes!!! if one is just out a little bit in redrilling these new bigger holes ...this joint at the turbo exhaust elbow will leak black soot in the engine bay!! so here is my attempt to make a an exhaust down tube clamp!!! :popcorn:

3.. take a small little drill bit & drill around the edge of the black marker line around the hole!!

4..take a small sharp chisel & try to knock out chunks of metal!!

5..get all the metal you can get out of it using needle nose pliers ..!!

6...walk over to the drill press & put in a reaming bit!!

1..and bingo... it looks like this thing might work!!!

2...drill just wee tiny bit more with the reaming bit to make darn sure the exhaust down tube will be centred...

3..and it fits nice & it is a start of my exhaust down tube!!!

:wave: 1... well the tractor is down for a day.....well i might as well work on little diesel truck!!!(john deere tractors are like Spanish onions painted green...the more layers you peel off of it & find out how much its costs to repair it ...... the more it will make you cry!!! )

2.. the 4d56t oil filter assembly has a real weird thread, so i was wondering if anyone knows what type fitting this takes or even know what one would call this fitting!!!(i didn`t get these hoses or fittings when i bought this 4d56t engine)

3..the oil cooler line from 4d55t male end hose that supposed to go into the fitting!!!(looks like a standard power steering hose end to me)

4..this is a fitting off the d-50 ... the fitting i want to know what is it called so i can order 2 of them...(with the correct thread) boy... i never knew about this,that the thread is different from the d-50 4d55t oil filter assembly to a 4d56t oil filter assembly!!!

5...another pic of the d-50 4d55t fitting.... !

6...can`t find a fitting no place that will fit the 4d56t oil filter assembly on 1/4 ton row...so i installed all of the d-50 4d55t oil filter assembly to the 4d56t block!!all because of a darn unknown male thread fitting!!! i robbed this d-50 4d55t oil filter assembly off this 2x4 truck( http://idahoturbodiesels.com/vb/attachment.php?attachmentid=6771&d=1423627596) & I want to rebuild its engine so i will need this fitting someday!!
